So you want the longevity benefits of regular exercise but you've hit some snags.  Every routine pretty much makes you miserable.  In addition, because of all the conflicting information out there, you aren't even sure if you're getting the full benefits.  This post is for you.  And don't worry about your current physical circumstances.  It works equally well for the overweight, the underweight, and women (no you will not turn into a gross she hulk the moment you touch a weight.  Those women take steroids and train hard for years)  

A sub-optimal plan you stick to is better than the perfect routine you abandon after the first week.  This routine is not perfect.  This routine is optimized for simplicity and low time/mental effort commitment while still getting excellent results.  It is strongly based on the routines from Beyond Brawn by Stuart McRobert, and some of the principles of Starting Strength by Mark Rippetoe both of which have much anecdotal evidence of effectiveness in the training logs of various forums.  If you're looking for published research to back up my claims I have some bad news for you, the literature on resistance training is basically worthless.  A 5 minute perusal of google scholar will show that atrocious methodology such as having "subjects act as their own control" are common, and accepted by the relevant journals.  And that's if you're lucky enough to find studies that aren't about diabetics, or elderly japanese women.  But I'm not going to spend excessive time trying to justify this routine, anyone can do it for a month and see that the results are significant. (I'm open to arguing about it in the comments however.)

 

A note about cardio:  

Cardiovascular capacity (V02 max) has shown a high degree of correlation to all cause mortality.  Why aren't I recommending cardio?  Because the only way to increase V02 max is with high intensity exercise.  Between high intensity weight lifting and high intensity cardio, high intensity weightlifting easily wins for a newbie.  A newbie, especially a significantly out of shape one, will not be capable of a level of cardio exertion that results in a significant adaptation.  This can result in a lot of effort with very little in the way of improvement.  This is soul-destroyingly frustrating.  They can however lift a weight a few times and this will result in an adaptation that allows them to lift more next time.  A few months of a weightlifting routine is going to put any person in a much better position to do longevity affecting cardio if that is their goal.  Cardio is also generally a terrible fat burner for the exact same reason.  

Edit: there seems to be some confusion about this.  The primary problem of exercise is not the optimality of results but instilling the habit of exercising. I believe that cardio is terrible for overcoming this habit forming stage.  

The point of the below program is to get you in the habit of exercising and give you immediate results.  Once you have achieved some basic measure of fitness (~3 month time frame) you can maintain, or use the fact that exercising is now much easier to move on to any program you want. 

 

The nitty gritty:  

You are going to do three exercises 2-3 times per week.  Each session will take ~45 minutes to an hour.  The exercises are

* 3x5 trap bar deadlift

* 3x5 incline bench press

* 3x5 bent over row  (possible substitution for cable rows see below)

What does 3x5 mean?  

3 sets of 5 reps each.  You will assume the correct form, go through the full range of motion for the exercise 5 times, then rest before repeating twice more.  

What weights do I use?  

You will start with the empty bar and add 5lbs every workout for the trap bar deadlift and 5lbs every other workout for the incline bench press and bent over row.  Many are tempted to increase weights faster than this.  You can do what you want but don't come crying when your progress stalls more quickly.  A slow progression that continues for a long time beats a fast increase followed by a time wasting plateau.  

Why these three exercises?  

This routine hits the most muscle mass possible in the smallest number of exercises.  All decent routines include hip extension exercises, pushing exercises, and pulling exercise.  This ensures that you don't create an imbalance that messes up your posture or limits you unnecessarily.  In addition, these exercises require very little in the way of technique coaching, which is really this routine's primary advantage over more popular programs such as starting strength.  It took me 8 months to learn to squat well, but I learned to trap bar deadlift in a single session.  Similarly with the incline press, it carries with it a much smaller chance of injury from poor form than either the bench press or overhead press that are the mainstays of many programs.  

I have no idea what these exercises are, how do I do them?

Here is an article for trap bar deadlift, which is so easy that there aren't really many tutorials online:  

http://www.t-nation.com/free_online_article/most_recent/the_trap_bar_deadlift  

The key is a neutral spine.  You take a big breath at the bottom, squeeze everything tight, and stand up pushing through your heels while maintaining the lumbar arch.  Note not to use the raised handles that many trap bars have which reduces the range of motion.

Incline is similarly straightforward:  

http://www.youtube.com/watch?v=dynoKEIcpoU  

note that you DO want to touch your chest at the bottom, but do not bounce the bar off your chest.  The cue that works for most is to imagine touching your shirt but not your chest.

Bent over row can feel a little weird, but it's not too hard to learn:  

http://www.youtube.com/watch?v=boxbOSGwD4U  

Note that after more real world testing bent over rows seem to cause the most issues of the three lifts.  As the potential for injury is slightly higher with poor form for this exercise than the others I would recommend seated cable rows for those who find they can not perform bent over rows correctly.  I'd additionally strongly recommend that if one is forced to make this substitution they should also do some chinups at the end of each workout.  The goal of this substitution should be as a temporary measure.  One should strive get back to doing bent over rows once physically able to.

Cable row form video here: http://www.youtube.com/watch?v=HJSVR_63eKM

How do I warmup/cooldown?

the best warmup and cooldown is 5 minutes on the rowing machine:  

http://www.youtube.com/watch?v=H0r_ZPXJLtg  

But you can also do an exercise bike or treadmill.  

After the first couple weeks you should also warmup with the empty bar before jumping to your 3x5 work weight on each exercise.  Add additional warmups as the weights get heavier.  

e.g.

1x5 45lbs  

1x5 75bs  

3x5 105lbs  

don't worry excessively about this, it's hard to screw up.  The key is just to prepare yourself, remind yourself of proper form, and get blood flowing.  Don't skip warmups, you're increasing your chance of injury and ensuring that you won't get strong as fast.  

Can I do this once week?  or sporadically?  

You can but you won't see hardly any benefit other than maintenance of your current fitness level.  2 times a week is the bare minimum to disrupt homeostasis to any appreciable degree and 3 is better.  Make no mistake, even 2 times a week on this will get you miles ahead of most people fitness wise.  You should program it like AxxAxxx or AxAxAxx, where A is a workout session and x is a rest day.

Can I sub in X exercise?  

No, the bare minimum nature of this program leaves no room for changes.  Any change necessitates more complicated programming.  If you want to do that just do Starting Strength.  Likewise if you want to add stuff, like ab work.  It isn't necessary.  Edit: cable row substitution for bent row is permissible but only if one finds they absolutely can not maintain good form with barbell rows.  

I didn't complete all my reps this session, what do I do?  

Back off the weights by 10-20% and work your way back up.  Make sure you're eating and sleeping right.  If you keep hitting a wall over and over again it will be time for a more complex routine.  

My gym doesn't have a trap bar.  

Find a gym that does or do a different program.  There is no replacement for the trap bar.  One option that is non-obvious is buying a trap bar for your current gym.  You might be able to negotiate a free month of membership or something but even if that isn't the case the investment is worth it.

What sort of results can I expect?

Most people should expect to be trap bar deadlifting their body weight within 3 months.  This will have several effects.

Strenuous physical activity becomes drastically less taxing.  

Chance of injury during said activity reduced.

V02 max increased.

Bone density and joint health improvements.

Increase in lean body mass.

Improved insulin sensitivity.

Improved blood markers and pressure (increases HDL and lowers LDL)

Decreased chance of back problems.

Improved posture.

Mental benefits:  Most people find the quality of their sleep improved as well as an increase in general energy levels.

 

A note on nutrition:  

80% of body composition is diet.  This won't do much for your body composition if your diet is crappy.  Luckily nutrition is fairly easy, there are only 2 rules to follow:  

*Calories in calories out  

*Eat micronutrient dense foods  

if you follow these rules it's actually surprisingly difficult to mess up.  Most people also find that following the 2nd one makes following the 1st one much easier.  

That's about it, I will answer questions about anything I forgot.  I hope this gets some fence sitters exercising.

Thought this might be a good place to dump some excerptions from evernote:

Review: Energetics of Obesity and Weight Control: Does Diet Composition Matter?

Greater average weight losses (2.5 kg over 12 weeks) have been reported for low-carbohydrate diets (25% of energy) diets. Nonetheless, diets high in protein, but either low or modest in carbohydrate, have resulted in greater weight losses than traditional low-fat diets. We speculate that it is the protein, and not carbohydrate, content that is important in promoting short-term weight loss and that this effect is likely due to increased satiety caused by increased dietary protein. It has been suggested that the increased satiety might help persons to be more compliant with a hypocaloric diet and achieve greater weight loss.

...energy deficits realized by a person will be smaller than the energy restriction because the three components of total energy expenditure (thermic effect of food [TEF], resting metabolic rate [RMR], and the energy expended in physical activity) decrease in response to an energy deficit and weight loss. If a person decreases energy intake, the TEF will decrease by an amount roughly equal to about 10% of the decrease in energy intake. Following energy restriction, RMR will also decrease, first as an adaptive response to the energy deficit and then as a result of smaller body size. Finally, the energy costs of physical activity will decrease for the same physical activities, also as a result of smaller body size (4). When reductions in these three components of total energy expenditure are averaged over a 12-week weight loss, they reduce the predicted energy deficits by one fourth to one third.

Still, the basic relationship between body energy stores and energy deficit shown in the Table [see pdf] suggests the greater average weight losses reported for low-carbohydrate diets are due to a 233 kcal/day greater energy deficit. What might cause this greater energy deficit? Is it due to metabolic advantage, or a difference in energy intake? ... [Exposition of studies for following conclusion -- ketogenic diet referenced]. ...Taken together, these studies provide little support for the hypothesis that a low-carbohydrate diet increases energy expenditure and, if anything, a low-carbohydrate diet may decrease energy expenditure, particularly if the carbohydrate intake is very low.

[Similar conclusion with high-protein diet followed, but results are better than low-carb.]

Combining the results of these studies, there is an effect of dietary macronutrient composition on energy expenditure, but the effect of substituting fat for carbohydrate is generally small and in the opposite direction needed to support the suggestion of a metabolic advantage. In the case of the two studies that substituted protein for carbohydrate, the effects were contradictory. Thus, these observations do not explain the 2.5 kg, or more, greater weight losses reported for low-carbohydrate diets compared with traditional low-fat diets and thus do not support the hypothesis of a metabolic advantage for low-carbohydrate diets.

If the effect of dietary macronutrient distribution on energy expenditure is minimal, what else might explain the greater weight loss observed for low-carbohydrate or high-protein diets? The likely explanation is greater dietary compliance. Thus, on a theoretical basis, low-carbohydrate diets with a high protein content are producing the expected weight loss, whereas low-fat diets are not. Given the minimal effect of macronutrient composition on energy expenditure, the most likely explanation of the greater weight loss is that participants complied with the energy prescription of the low-carbohydrate/high-protein diet, but not the low-fat diet. In support of this, it has been reported that protein has a higher satiating effect than carbohydrate; thus, a high-protein diet may help participants comply with energy restriction.

A second factor that can contribute to improved compliance is the limitation of food choices associated with low-carbohydrate diets. Many foods are not permitted in low-carbohydrate diets because they contain too much carbohydrate.

In addition to improved compliance, low-carbohydrate diets are also known to induce small losses of body water that can contribute to weight loss.The loss of liver and muscle glycogen secondary to carbohydrate intakes below that required to sustain glycogen stores results in water loss of 1.9 kg in the first 10 days of a very–low carbohydrate diet (12). This contributes to the early rapid weight loss often reported by participants consuming low-carbohydrate diets. Aside from the weight itself, this water loss may also help participants comply with their diets during the early phase of the diet, because modest increases in carbohydrate intake will result in the return of the glycogen stores and associated water. The water will result in a small rapid weight gain that may serve as negative feedback and help direct the participant back to compliance.

Review: Diet in the management of weight loss.

Low-calorie diets can lower total body weight by an average of 8% in the short term. These diets are well-tolerated and characterize successful strategies in maintaining significant weight loss over a 5-year period. Very-low-calorie diets produce a more rapid weight loss but should only be used for fewer than 16 weeks because of clinical adverse effects. Diets that are severely restricted in carbohydrates (3%–10% of total energy intake) and do not emphasize a reduction of energy intake may be effective in reducing weight in the short term, but there is no evidence that they are sustainable or innocuous in the long term because their high saturated-fat content may be atherogenic. Fat restriction in a weight-loss regimen is beneficial, but the optimal percentage has yet to be determined.

Which diets result in safe weight loss, have positive long-term consequences for chronic disease risk factors, and are sustainable in the long term? This question has been only partially answered. Comparing dietary trials is difficult for several reasons: diet compositions vary in the amount and type of carbohydrates and fats, amount of protein, and degree that energy intake is restricted, all of which have intricate bearings on weight regulation; diets have specific actions on appetite and food preference that affect drop-out rates; study populations may have different associated diseases that modify outcomes; and the choice of statistical analyses can bias results.

The National Institutes of Health reviewed 34 randomized controlled trials to assess the effectiveness of low-calorie diets for lowering body weight, decreasing abdominal fat and improving cardiorespiratory fitness.8 The review concluded that low-calorie diets can lower total body weight by an average of about 8% during a period of 3–12 months (evidence category A). Weight-loss and weight-loss maintenance interventions lasting 3–4.5 years (4 studies only) resulted in an average weight loss of 4%, well below the definition proposed for successful weight loss (a decrease in 10% of body weight sustained for more than 1 year).7 Low-calorie diets resulting in weight loss also lower the amount of abdominal fat, as shown by a reduction in waist circumference of 1.5–9.5 cm (evidence category A). The National Institutes of Health review also concluded that low-calorie diets alone do not improve cardiorespiratory fitness as measured by maximum rate of oxygen consumption (evidence category B),8 which reinforces the importance of combining diet and exercise programs in weight-loss interventions. Behaviour therapy in conjunction with dietary interventions (including low-calorie diets) has been shown to result in additional weight loss in the short term (1 year) but not in the long term (3–5 years) (evidence category B).

There is a debate regarding the effectiveness of low-fat diets in weight reduction.23–28 Astrup and colleagues26 conducted a meta-analysis of 16 trials of 2–12 months' duration, of which 14 were randomized. They reported that low-fat diets without intentional restriction of energy intake resulted in greater weight loss (3.2 kg, 95% confidence interval 1.9–4.5 kg, p < 0.001) than did habitual, or medium-fat, diets ad libitum. ... The National Institutes of Health review also concluded that lower-fat diets (20%–30% of total energy intake) contribute to lower energy intake; there is little evidence that low-fat diets with no reduction in energy intake result in weight loss.

We still have no definitive answer as to which diets sustain long-term weight loss. The National Weight Control Registry in the United States provides useful information regarding successful weight-loss maintenance strategies.81 This registry includes people who have lost more than 13 kg of body weight and successfully maintained that weight loss for over 5 years. Over 4000 people are in the registry. The dietary pattern generally shared among participants included low amounts of fat (about 24% of the total daily energy intake), high amounts of carbohydrate, and a low energy intake (5460–6300 kJ/d). Most eat breakfast daily, self-monitor weight and are physically active. Other studies report similar strategies for successful weight-loss maintenance, such as monitoring food portion sizes, energy and fat intake, and body weight, and avoiding the use of food to regulate mood.

Overall, low-calorie diets are a safe strategy for weight loss. A sample 5040-kJ diet plan based on Canada's Food Guide to Healthy Eating is outlined in the online appendix (available at www.cmaj.ca/cgi/content/full/174/1/56/DC1). A sedentary woman 45 years of age with a body mass index of 31 kg/m2 (height 167.6 cm [5'6"], weight 87.5 kg [192.5 pounds]) and an energy requirement of 7988 kJ per day (calculated using the Harris–Benedict equation) can achieve a body mass index of about 26 kg/m2 after 6 months on a 5040-kJ/d low-calorie diet. ... Low-carbohydrate diets and diets high in saturated fat are not recommended.

Successful Weight Loss Among Obese U.S. Adults

Purpose: To identify strategies associated with losing at least 5% and 10% of body weight.

Sciamanna and colleagues identifıed 14 strategies reported to be successful for 10% weight loss among a national mail panel survey, reporting the strongest associations for weight loss programs, eating fruits and vegetables, eating healthy snacks, limiting carbohydrates, controlling portions, doing different kinds of exercises, and focusing on the progress they had made. Among members of the National Weight Control Registry, the most common strategies associated with success included restricting types of foods, limiting quantity of food, and counting calories.

Results: Of 4021 obese adults, 2523 (63%) reported trying to lose weight in the previous year. Among those attempting weight loss, 1026 (40%) lost ?5% and 510 (20%)lost ?10% weight. After adjustment for potential confounders, strategies associated with losing 5% weight included eating less fat ; exercising more; and using prescription weight loss medications. Eating less fat; exercising more; and using prescription weight loss medications were also associated with losing 10% weight, as was joining commercial weight loss programs. Adults eating diet products were less likely to achieve 10% weight loss. Liquid diets, nonprescription diet pills, and popular diets had no association with successful weight loss.

The present study has several limitations. Because this is a cross-sectional observational study based mostly on self-reported information, results suggest associations and do not signify causality.Although there is likely reporting bias for body weight,this study demonstrates a high correlation between self-reported current body weight and measured body weight.

My general impression, based on the post and the general tone and content of the author's responses, is that this is yet another attempt at spouting advice without the backing of theory. Main points:

  1. Why should anyone believe this ad-hoc program has a chance of working for them better than, e.g., SS?

  2. Why is improving cardio capacity the only reason to do cardio?

  3. Why subscribe to calories in calories out when it is painfully, obviously wrong?

3.) It is painfully and obviously wrong. We don't burn food, our metabolic processes are vastly different than the measuring techniques used in the lab.

But that doesn't mean that it can't also be right.

I put together a spreadsheet because I thought that calories were clearly stupid; I went around online and found formulas for calculating my caloric requirements. I put in my initial weight, and created two columns; one for my measured weight, and one for my predicted weight. And then I tracked everything I ate, over a three month period, as well as my body weight, and (using an electronic scale), my fat percentage.

And, much to my surprise, calorie consumption predicted body weight.

So, even if the assumptions behind calories have some clear holes in them, they nonetheless (for this sample size of one extremely skeptical individual) have at least -some- predictive value.

Even if everything you say is true (and, e.g., you weren't recording completely bogus fat percentage numbers, you measured your weight consistently, the internet didn't mislead you on calorie counts, etc. etc.), this gives you extremely weak evidence to expect that other people would benefit from doing the same.

Not that this argument hasn't been tried before.

It is weak evidence, bordering on if not outright in anecdotal, which is why I was careful to indicate that the predictive value is limited. And my body fat percentages probably were not precise - it's an electronic scale - but they were at least consistent, which was enough for my accuracy purposes. And yes, I measured my weight consistently; I measured once in the morning when I got up for work, once in the evening while preparing for bed, and averaged these values.

I will also add that I follow a relatively well-balanced diet, and wouldn't expect the results to hold as well if, for example, I consumed significantly fewer carbohydrates.

I started out an extreme skeptic. But I tested the theory instead of rejecting it. Well, to be completely accurate, I rejected it, and mocked some people who held to calories, and then later decided I should test my hypothesis instead of relying strictly on my intuition on how food works, and was entirely taken aback by the results.

As for your link, I'm not arguing for a position I think is a good one; if anything, my bias going into the experiment was expecting it to fail miserable. I'm defending one which I initially opposed, and still think is probably bad, but nonetheless works at least some of the time.

Congratulations. I revived this account, which I haven't used for years, just to downvote your crazy ass.

The evidence for the general principle - that weight change tracks the difference between calories eaten and calories expended - is overwhelming.

I have seen no fitness advice that suggests it isn't true. I have seen no fit person who doesn't accept it.

For the past 6 years, I have reduced weight and controlled it very effectively based on this principle. Time and time again, I have become fatter when I stopped counting calories and ate to my heart's content. Time and time again, I got my weight under control after I resumed calorie restriction.

If you want to show that calorie restriction doesn't work, you first have to overthrow conservation of energy. And then, explain how come no one was fat in Dachau.

If someone sounds crazy to you, maybe you have misinterpreted them.

The original post said that nutrition was "fairly easy", and that one should follow the rule of "calories in, calories out" and that one should eat "micronutrient dense food." CI:CO is broken because it's difficult to measure CI with any accuracy and intractably hard to measure CO. It ignores all sorts of subtleties like getting enough protein in your diet and the difference between bulking and cutting.

For example, good luck seeing gains if you're eating 20% fat, 70% carb, and 10% protein on a 10-15% caloric deficit. All the micronutrients in the world won't save that diet. But you're still following CI:CO!

Sigh. If this point is really so hard for people to get, maybe it's just not worth making. It's probably easier to let LW devolve into a bunch of badly-sourced self help advice than to continue tilting at windmills.

It's not so hard to measure calorie intake. Just memorize the relative base amounts of calories in the composing parts of one's meals, and learn to judge when one is hungry from physiological cues (ergo gratia consistently drinking water in sufficient amount that the scratchy, parched feeling at the back of one's throat indicates hunger and not thirst, the difference between digestive sensations and starving sensations, where one's stomach is, etcetera).

Once one learns how to tell when one is hungry, and how hungry, they can estimate how many calories lasts one how long, and thus measure one's average caloric need per hour, and therefore one's caloric need per day. Since it takes about twenty minutes to have an accurate sensation of hunger or satiety, at first one's estimates will only be accurate to within about 100 calories. As one tests their predictions of how many calories one needs per hour by: eating, judging when one will next be hungry based upon the estimated amount of calories consumed, then losing oneself in a non-stressing activity until one feels hunger sensations; noting the time one feels the sensations, if the time is when one predicted they would next be hungry, and if one is fairly certain one isn't guilty of a bias or a bias blind spot (good on one if they can detect these); one can accurately estimate to within about 50 calories their caloric intake.

Caloric outtake could then be measured by being slightly hungry when going to sleep, and tallying up the total amount of ingested calories that day (caloric intake per 10-16 waking hours).

Note this may take one a couple of years.

[...]

Note this may take one a couple of years.

Please recognize that this advice is really quite far from what the original poster was proposing, and uses a radically different assessment of difficulty.

Your method of measuring caloric outtake is wrong, because the body doesn't use only the calories ingested that day during that day. (Yes, perhaps the calories ingested from the past and used today can be balanced out by the calories ingested today and stored for the future, but that assumes a whole host of processes are weakly varying over a long period of time.)

Having said that, I prefer your method to any other method I'm familiar with, perhaps even to the point of implementation...

Your method of measuring caloric outtake is wrong, because the body doesn't use only the calories ingested that day during that day.

I suppose so, but as long as one's caloric intake caters to cues from physiological needs (which can be co-opted by MSG and to a lesser extent HFCS and sugar alcohols, and should thus be avoided at most costs), measuring one's caloric outtake doesn't really matter so much. I'm trying, but can't see how knowing caloric outtake would be necessary when the sole criterion for calorie intake levels is physiological need, as determined by learning the cues. If one learns their average hourly caloric need at relative metabolic rest, one can judge whether they have over- or under-eated. Learning one's average heart beats per minute, and what different degrees of elevated bpm feel like, they can additionally learn by what estimate exercise increases their caloric need.

The one caveat to this, though, would be if one has imbalanced ghrelin and leptin levels - that would disable one's ability to trust their body's cues. If this condition is a concern, I think it can be tested through blood work.

However, maintaining a steady rate of metabolic activity is crucial to learning one's average caloric need per hour. Drinking cold water to just adequate levels of hydration (as judged by urine color), and consuming calories at a rate sufficient to maintain near-constant levels of digestion are of tremendous help in achieving this. I'd recommend erring on the side of unnecessarily diligent hydration (consistently clear urine) when learning what is the 'just-right' amount of hydration for one's body; learning what this amount is may take a while.

I can go into detail about why maintaining near-constant levels of digestion is helpful, but I think it might be unnecessary, and will thus abstain.

Having said that, I prefer your method to any other method I'm familiar with, perhaps even to the point of implementation.

As you may have gathered, this is essentially what I do (at the most basic level). I cannot yet accurately judge its effectiveness as a strategy, considering I may still be young enough for my naturally-high metabolism to significantly confound other variables' effects. There are also many other factors to consider, like blood sugar levels, inflammation, certain types of foods' effect on immunological processes and such processes corresponding effects upon digestion, etcetera.

In general, though, the logic should be sound. In regard to its difficulty, since becoming fluent enough with one's physiological cues takes a while, the effort expended may sum to a very high net amount of expended effort. During acclimation, however, only minimal amounts of effort would need to be expended at any one time (even less if one already has self-control/self-discipline).

I suppose so, but as long as one's caloric intake caters to cues from physiological needs (which can be co-opted by MSG and to a lesser extent HFCS and sugar alcohols, and should thus be avoided at most costs), measuring one's caloric outtake doesn't really matter so much. I'm trying, but can't see how knowing caloric outtake would be necessary when the sole criterion for calorie intake levels is physiological need, as determined by learning the cues.

We're in complete agreement here.

What I'm arguing against in my comments above is the standard implementation of "calories in, calories out" (as seen in popular self-help dieting books and even in such august bodies as r/fitness, for example) does not involve learning physiological cues at all (rather, usually, ignoring them as "bad") but instead attempting to count the calories in the food one eats, come up with some justification for a value for BMR, estimating additional expended calories due to exercise, and so on.

The more I think about your method, though, the more I like it.

I haven't checked this thread for a while, so sorry for the late reply.

You make it out as though diet by CI:CO is too difficult to be practical. Maybe it is, for people who can't track stuff to save their lives.

For me, it's been easy. When I'm dieting, I have a spreadsheet where I record the calorie and protein content of everything I eat.

Yes, calculating calorie content for homemade meals is a fair amount of work, and takes dedication. It takes me up to 30 minutes of lookups and calculations to calculate calorie and protein content in a meal, and that's after my wife has weighed and recorded all the ingredients.

Because of this complexity, I stick mostly to prepared foods that display their calorie content, or homemade meals made of well-known ingredients in well-known proportions.

I have a fair amount of confidence in my calorie calculations. I know from experience that when I keep the daily sum of calories under a certain level, my waist size goes down. It works.

I don't know anyone else who brings this level of dedication to their diet. I know people who don't, and so they're fat.

I accept your argument that CI:CO is hard for people lacking conscientiousness, but this is different from saying that CI:CO doesn't work.

Also, for people lacking conscientiousness, chances are that no diet is going to work.

My argument had nothing to do with conscientiousness.

There is currently no convenient way to accurately track your caloric intake and caloric expenditure. Attempts to do so have all the usual sources of error that this thread already covered.

In particular, adding up the numbers on the labels of the things you eat is not a sufficiently accurate method of determining caloric intake, see for example the FDA's Food Labeling Guide, questions N30-37. That's before we begin to talk about preparation loss ratios, nutrient bioavailability and the vagaries of the human metabolic system.

So when somebody recommends CI:CO, they're recommending either 1) vapid numerology or 2) a time-sink that is also largely numerology. It's unreliable, and therefore not something I would ever suggest to somebody else.

All your self-congratulatory narcissism is also largely off-topic. In particular,

I don't know anyone else who brings this level of dedication to their diet. I know people who don't, and so they're fat.

is such a bizarre source of evidence that I can't imagine why you bothered stating it. Is it really so controversial that pseudoscientific magic is bad advice?

If that's the case, why does it work?

I agree that calorie content of any particular meal is hard to measure accurately, but over time, the calorie content of many meals should gravitate towards the average.

You're going overboard by stating, not just that CI:CO is hard, but that it's impossible.

You're saying that my positive experience with CI:CO over the past 5 years, which I was able to confirm numerous times, is a fluke.

It doesn't only work for me. It's how most people I know, who are into fitness, manage their weight. The "Calories In" part is not eating too much. The "Calories Out" part is maintaining your metabolism by eating small meals regularly, exercising, and eating lots of protein to gain and preserve muscle mass.

It works. It works for a lot of people.

In fact, aside from gastric bypass surgery, it's the only reliable way to lose weight that I know. And gastric bypass surgery is a form of CI:CO!

And then we have a bunch of people on Less Wrong, all of whom appear to be convinced that human bodies can somehow violate the rules of thermodynamics. Or that the calorie content of foods varies so wildly no one can ever track it well enough to lose weight. Then when challenged, you resort to arguments like this:

  • The sun is dark green.
  • No, it's bright yellow, I saw it this morning.
  • That's anecdotal evidence. It's no good as science. It's green, stop spreading your bullshit.
  • I'm pretty sure that it was yellow every time I saw it in my life. It was never green.
  • More anecdotal evidence. What you see is not what other people see. Learn to science, man!

  1. It won't work better than SS. It is explicitly not supposed to be an improvement to SS in terms of results. It is an improvement to SS in terms of time/mental commitment. The 5 exercises SS asks you to learn are all difficult and require a willingness to watch videos, read articles, and continuously check your form. The 3 exercises from this routine can be learned ridiculously quickly. People who use it will see a result close to the results from SS.

  2. This article is mainly for people who don't like exercise and thus are interested in health benefits with minimal input. If you're interested in cardio for some other reason, great, have fun.

  3. If it is painfully and obviously wrong there should be plenty of studies on people who maintain their caloric consumption and activity level but change whatever you think is the true culprit and lose weight. The main reason people think CI:CO is not true is due to errors related to not accounting for BMR and TDEE change.

  1. Already covered by wedrifid elsewhere, and I largely agree with his analysis of your routine.

  2. "Health benefits" does not mean the same thing as "reducing mortality", which in turn does not mean the same thing as increasing cardio capacity. You dismissed cardio because of the third, but addressed it to people looking for the first.

  3. Who is your audience? Now it seems like it is people who don't like exercise but are also willing to do enough calculation and lifestyle management to make CI:CO even remotely applicable. It seems far more likely to me that a significant proportion will fall into one of the well-documented failure modes associated with such advice, e.g., malnutrition, neuroticism, burnout, and etc.

Why subscribe to calories in calories out when it is painfully, obviously wrong?

There are two ways to represent the statement "calories in calories out".

The first way assumes that if you eat X calories - then you will gain X calories-worth of fat. This is painfully and obviously wrong. One calorie (as measured in the lab) does not equate to one calorie of body fat. There are all sorts of complicated reasons why this is so.

The second way is to realise that if I ate no calories, and only expended them - I would have a net loss of fat. If I ate way too many calories,and expended none - I would have a net gain of fat.

So... 1 calorie in does not exactly equal 1 calorie of fat gained... but there is still obviously some correlation between intake of calories and the laying-on-of fat.

Therefore, if I restricted the intake of calories (ie reduced calories in) while maintaining the calories out... I would at some point expect to see a reduction in the amount of fat on my body. Likewise if I increased the calories going out (while maintaining the calories coming in) I would also see a reduction in my body fat.

Therefore "calories in... calories out" DOES work as long as you don't assume that "calories in - calories out == 0"

because THAT would be painfully and obviously wrong.

I know you said you don't want to put in the effort to justify this program, but I'm curious what your evidence is that it works close to as well as Starting Strength. SS was optimized empirically over the course of years and large numbers of people, so just porting over the theory from SS seems unlikely to be enough to get good results. Note I'm not claiming that's what you're doing, just explaining why I'm initially skeptical. I currently am in a position where many newbies ask me for workout recommendations, so I would love to be able to recommend something easier than SS, as long as it actually works.

Note that I think SS (with Power Cleans substituted out) is not actually very difficult, provided you have someone competent around to critique your form. The main disadvantage I see is that many gyms don't have a squat rack, so it's harder to find a good place to do the necessary lifts.

this is based more strongly on a popular Beyond Brawn routine than SS. The rep scheme is SS. The major change is incline bench instead of switching back and forth between flat bench and overhead press. EEG scans of muscle activation is some evidence this is fine (works pecs, anterior delt, and triceps about equally). the reason for the SS rep scheme instead of the original BB one is that the success of SS shows that newbies can handle a bit more volume than he (Stuart) thought.

As the laws of thermodynamics, yes; applying it to fitness is intractably hard, and attempts to approximate caloric intake/expenditure for that purpose have all been intractably difficult or laughably bad.

So while you are learning to do double unders, I would maybe just do 5-6 sets of regular jumping to a certain number so that the last 3 sets are very challenging. One or two sets won't cut it.

Thanks for sharing this - from my understanding of exercise response it seems like an excellent program for building fairly significant improvements in strength, muscle mass and thereby weight loss. I'll endorse almost any program that advocates:

  • Several multiple muscle group exercises distributed such that most key muscle groups get to play in at least one of them.
  • Keeps the sets moderate (3 is about perfect) and reps moderate to low.
  • Does not include an excessive number of exercises (ie. No overtraining specific musclegroups by doing 5 different bicep exercises, etc.)
  • Recommends no more than 2-3 weekly weight training days per week.

Some of the net negative response you have received so far may be because you set up expectations that your program would be something else entirely. This is decidedly not the "minimum viable workout routine". It isn't even close to the minimal viable workout routine on any of:

  • Time spent - Off by an order of magnitude. Three days doing three different high intensity weight bearing activities isn't the best overall workout program but it is certainly viable and far more minimal. It would give acceptable (but less) muscle growth and far better cardio improvements.
  • Efficiency - This is a good, moderate workout program, but not minimal effort for maximal results.
  • Difficulty - None of those exercises are particularly simple for beginners and require more than average amount of practice to get form right in order to be safe.

The justification for (but not necessarily the conclusion of) "don't do cardio" as well your "just calories in calories out" emphasis really distract from your actual program. We become tempted to write off your advice as uninformed based on your somewhat eager defense of those two side-notes. Yet once I force myself to look past the extra crap and actually look at the workout program the weightlifting advice seems sound.

I've never actually used the trap bar. You've prompted me to try it out. Back squats annoy me and I'm not a huge fan of deadlifts. The reduced back-strain potential for this exercise may make it worthwhile. The main downside may be the strain on the wrists - my right wrist is my weak point so I avoid too many exercises that rely on plain tension at the wrist.

If you are not having fun, there is little chance of long-term success. Personally, I hate workouts, and any kind of weight lifting bores me out of my skull. Instead I go play ping-pong, or badminton, or beach volleyball (when in season) instead. The downside is that you need a partner or a team, and your workout is not overly scientific, the upside is that the time passes quickly as you socialize as well as exercise. Which leads me to the most important upside: looking forward to doing it again, instead of dreading it. YMMV.

I like this post, since it is pretty useful content, and, based on my limited knowledge, seems reasonable. However, there are many nearby recommendations in this space that would probably not be as reasonable, and many people would be unable to judge. I think it would be good to have some community norm around "recommendation" posts like this that filters for reasonable advice. I'm not entirely sure what the best thing to do is, but one idea would be to ask such posts to make concrete predictions, and have people follow up with their reports later of whether the predictions held.

For instance, in this case, RomeoStevens can probably make fairly concrete predictions of what sort of strength and other gains people will have conditioned on doing these lifts twice a week for a month (or two months perhaps). I think making those predictions explicitly would be useful, both for vetting the method and for calibrating against possible oversights (for instance, I've found that women are quite different from men when it comes to strength training, so perhaps this advice works really well for people sharing RomeoStevens' gender but not for the opposite gender, or maybe it works really well for both genders).

For this post, I would guess the prediction is steady progress for at least 6 weeks (for males) before the given linear increase rule necessitates a reset. I suspect females need to progress more slowly to get ideal long-term gains, but I'm not sure.

From my experience as a female lifter who trains with other females, females do not need to progress more slowly to get long term gains. 5 lb increases per week on a deadlift and every other week on the other exercises is very, very reasonable (possibly too reasonable) in non-skill based moves like these. Even females should be able to experience a few months of lifting heavier each time if they follow the weight increase guidelines here.

However, smaller females (less than 110lbs) or those who have never really worked out might need to start with a lighter bar for rows and the incline bench press. Most gyms have mini-bars with weights permanently attached to the end, usually ranging from 10-80 lbs (how heavy they are should be listed on the side), so look around for those if you don't think you can bench 45 lbs or you don't have a spotter.

While I have never done a trap bar deadlift, I am going to assume its similar to a regular deadlift in terms of weight, but with less pressure on the back. So I would say that deadlifting just the bar (trap or not) shouldn't be a problem even for smaller women.

My prediction is that non-very overweight people should make it to bodyweight trap bar deadlifts with maybe 1 or 2 stalls on the way before hitting a wall. Young underweight males who start eating more calories will make it significantly farther.

Bodyweight is around where people start to stall on squats in SS when they don't have their diet on track. Most people can lift a little more with the trap bar than in squats.

Upper body is a bit harder to judge, some people struggle quite a bit, others make fairly steady progress (including some women).

Minimum viable workout routine

Kettlebell swings tabata. 4 minutes. Every second day. Will raise V02 max at a rate acceptably close to as fast as possible and give a strength adaption that is fairly general. Fat burning is increased both from the metabolic effect from the high intensity work and the increase in muscle mass.

This is minimal in terms of time, the complexity of the routine and materials needed. For the 4 minutes in question it is not minimal. It is more brutally intense than most things you can do short of physical combat.

I seem to disagree with your advice. It is approximately backwards. Running out of gas is kind of the point. High intensity is the point. Beginners should increase the rest time between high intensity excersions (for example 20 seconds on, 30 seconds off instead of 20 seconds on 10 seconds off). Doing just weights is a massive copout. Especially for beginners whose lack of neuromuscular adaptation ensure that they can't even perform at their full intensity at raw weight lifting when trying to.

Beginners for most part physically can't get burned enough to cause significant cardiovascular adaptation when weightlifting. This is why your workout proposal is quite good as far as a selection of exercises for muscle growth goes but the justification that it is somehow better in the cardio section is a little too eager.

I love weights, these days I do more weight training than running despite the fact that I'm training for a marathon. But choosing weights over high intensity cardio is a tradeoff, not a free-lunch improvement across the board. More muscle growth, more fat burning, much more cosmetic improvement, less cardiovascular improvements (including less VO2 Max). This applies to beginners at least as much as others.

I would make the same recommendation and add that cosmetic changes, the 'toughness feeling' and the comments from others will be a much more powerful reinforcement. The beginners also get much, much more perception of improvement in the initial stages of weight training than with cardio. Nearly all of the improvements are neuromuscluar as the nerves stop sending signals to the muscles that are utterly incompetent but even so ability to lift weights improves dramatically. You can't do the same thing with cardio; "Lungs! Absorb more oxygen and heart pump and stuff. Capillaries, grow!" is harder than "Opposing muscle groups, don't fire at the same time, dumbasses!"

"calories in calories out" still applies on the paleo diet, technically it applies to everything since it's just a restatement of conservation of energy.

It's just that effective diets typically reduce hunger, causing an automatic/involuntary reduction in calorie intake. Most likely by restoring the proper function of endocrine systems that are supposed to regulate hunger in response to feedback on fat mass (lipostasis).

That sort of thing is precisely why conservation of energy does not imply that calorie restriction must be an effective means of weight control. You have to know the causal relationships, not merely the correlations, even when the correlations follow from fundamental physics.

Fun anecdote: there was a period in my life, lasting several years, when I ate -- had to eat -- literally twice as much as I do nowadays (and I only use "literally" to mean "literally", never "hyperbolically"). I only weighed about five pounds more. If you want to imagine where it all went, go right ahead. (Yes, there was something seriously wrong. I got better, thank you.)

Yes, but people confuse "counting calories isn't a good strategy for losing weight" with "effective weight loss must occur by some mechanism that doesn't involve changes in calorie intake and expenditure- such as metabolizing different foods at different efficiencies."

I'm trying to clear up that confusion- calorie balance is critical to understand what's going on physiologically when people lose weight, however it's not very useful to track numerically when actually trying to lose weight.

Sure, you can make it a scientific tautology if you like... so long as when you say "calorie" you include every kg of mass absorbed, excreted or otherwise released as 2.2 × 10^16 'calories'. But if you want to talk about the numbers printed on the back of the food packet under "calories" you are talking about something entirely different.

You know, the first law of thermodynamics was discovered before special relativity.

OK, we're not interpreting “calories in calories out” that literally, but there are non-literal interpretations of it which still are very good approximation. If you interpret it to mean “it doesn't matter to anything at all whether you eat 2000 calories of proteins or 2000 calories of sugars” it's false, but if you interpret it to mean “the total number of calories you eat is usually way more important than where or when you get them from in determining how much weight you'll gain or lose, provided you're healthy enough and your diet isn't terribly unbalanced”¹ it is essentially true, and the main idea behind The Hacker's Diet by John Walker. ETA: And I don't think the next order of approximation should involve lumping wholemeal rice and high-fructose corn syrup together as “carbs” and extra-virgin olive oil and hard margarine together as “fats”.

  1. Or, more fancily, “If you e.g. eat epsilon more calories per day from fat and epsilon fewer calories per day from carbs, or epsilon fewer calories for breakfast and epsilon more calories for dinner, all other things being equal, the change in your medium-term weight-loss rate divided by epsilon will be quite small.”

I disagree, when people are losing weight quickly they almost invariably are eating far fewer calories. There's some technical exceptions (such as that different nutrients are absorbed at different efficiencies, etc.) but they're not large enough to make a huge difference in practice.

A lot of people think low carb or other weight loss diets work simply by preventing fat cells from uptaking glucose, in a low insulin environment. This is wrong, people losing weight on low carb diets are eating much less calories than they used to: if you were to force feed your old high calorie intake as fat instead if carbs, you wouldn't lose weight. You can argue about the biochemical mechanism by which hunger is reduced but the reduced calorie intake is obvious and significant.

For the most part, calories printed on the back of a box are a good approximation of how much energy your body will actually absorb from them. It's not something "entirely different." Diets work mostly by reducing hunger, not by decreasing metabolic efficiency or energy absorption from food (see the link I added to my original post).

The obesity epidemic has been accompanied by a massive increase in calorie intake... however before the obesity epidemic people weren't counting calories- they were just satisfied with less calories because their hunger was being regulated properly.

Then in as much as you yourself tried to make the claim a scientific tautology, a restatement of conservation of energy, you are plainly and trivially wrong.

Physics conserves energy as one of its fundamental properties. It so happens that humans are also good at conserving energy - and even reasonably good at treating our three main macronutrient sources as fungible - at least with respect to their use for energy production. That's the rather impressive product of billions of years of evolution. But saying that humans are able to do this because "technically it applies to everything since it's just a restatement of conservation of energy" is a ridiculous equivocation.

I never said or implied that humans can interchange nutrients from one form to another because of conservation of energy, there's plenty of examples of chemical energy that the human body can't do anything with. That isn't related in any way to the point I am trying to make.

I don't think I communicated clearly what I was trying to say, so I'll restate it:

You are right that merely considering estimated calorie intake, and estimated calorie expenditure is a drastically over-simplified model of what's going on that fails to account for many things.

However, it's accurate enough to meaningfully model weight loss in humans. When someone switches to a paleo diet and is losing 2lb/week (as happened to me for a solid 6 months when I did), it's not because they're using lots of energy by some mechanism not accounted for in the over-simplified calories in/calories out model.

If you estimate food intake, you will find that a person losing 2lb/week on a paleo diet is in fact eating roughly 7000kcals a week less food than they used to.

The paleo diet doesn't cause some metabolic condition under which the estimated calories in/calories out model is drastically inaccurate: it primarily causes overweight people to eat much less food.

I agree that compound lifts should form the bulk of your training, but I think most people will eventually need some isolation exercises too. If one muscle needed in the lift is less developed, people naturally compensate with other muscles, letting the weak muscle stay weak and the others grow until it becomes impossible to maintain good form.

My back squat and deadlift both stalled because of weak abs. They did not resume improving until I started doing ab wheel rollouts and various types of planks. Likewise, my bench was bottlenecked by relatively weak triceps and stalled until I added dips.

I also notice you're lacking any direct biceps work. This seems common with beginner routines, and I think it's because of the assumption that biceps curls are so popular that people will do them anyway even if they aren't listed. I did weighted chinups, but my back is much stronger than my arms so they didn't do much for my biceps. This isn't just an aesthetic issue, because biceps are important stabilizer muscles in many lifts, and you risk elbow injury if they are too weak. Don't go crazy with curls, but also don't completely ignore them in a misguided signaling attempt ("I'm not a curlbro").

It might also be a good idea to add a bit of knee flexion (eg. leg curl/GHR) so your hamstrings aren't just doing hip extension all the time.

I wouldn't necessarily limit these percentages to adding up to 100%. My genetic predisposition to cheat (against limitations but not rules I endorse) has to count for something and helps with body composition much more than nearly anything can. In fact the primary aspect of extreme success in any endeavor that seems to be heavily genetically influenced is that of extreme motivation.

The above said, I really do claim that for the same amount of differentiation from the mean in terms of genetic privilege or differentiation from the mean in control of calories it is the genetics that is the stronger factor.
