Can confirm. Did a year long dirty-bulk on a ketogenic diet while lifting heavy weights, got fat (and didn't really put on that much extra muscle either)...

What was your daily diet like?

Lots of eggs, bacon, beef, cheese, 35% cream and peanut butter.

I've found online reaction to this article quite interesting. Normally data and study minded folks bring out the "anecdotally, this doesn't seem true" responses, and people seem think the article is attacking exercise as a concept. It's not. It's saying that if a person's goal is to lose weight, then adjusting to a good diet is far more important than (a reasonable amount of) exercise. The article does not claim that…

"The education in popular culture around exercising presents it as a magic pill, as being a major driving force behind weight loss. You see this on magazine covers and on tv, "belly fat exercises", "toning exercises"" There's def some of that going on, but there's also a fair amount of fad diets - atkins, south beach, paleo etc etc popping up here and there. The fact that you get the 6 pack by dieting and not by doin…

> "losing weight" != "losing fat"

Does the article say so? And your so called "fad diets" that are low on processed carbohydrates out perform other traditional diets. I doubt that staying away from processed carbohydrates will go away any time soon.

I guess it's just a coincidence that most athletes aren't overweight. It doesn't have anything to do with them exercising?

Amusingly, if you go by BMI, quite a few pro athletes are overweight, or even obese. (This is a good illustration of how idiotic BMI can be...). For instance, Michael Jordan was slightlu overweight according to BMI. Shaquille O'Neal was past overweight and into obese. Wilt Chamberlin was overweight. Leaving basketball for boxing, Muhammad Ali was well into overweight. Mike Tyson was obese. How about American Football…

so true, I've never been in better shape in my life, I recently ran ultra-marathon and can easily bench press my own weight 10 times but my physician told me I am overweight and should loose 15 pounds because my BMI is over 25. I wanted to take his head off.

I'm going to continue to posit that weight is a factor of genetics / epigenetics and / or body function first and foremost. Why is it that some people, regardless of how much they eat and how little they exercise, never put on weight? That, to me, is the elephant in the room. What is going on in these peoples bodies that is kept out of popular science with regard to weight loss? We know that thyroid hormone function…

>There has to be more to it that calories in - calories out = weigh gain or loss.

There is. Read the "physiology" chapter at https://en.wikipedia.org/wiki/Adipose_tissue

TLDR: Blood sugar spikes above certain level are toxic, so the body responds with an emergency action of stashing the sugar wherever possible, including muscle, liver, and fat tissue. The former two are rather limited in their capacity, while the latter is unlimited. At the "hardware" level, that's all there is to obesity.

At the higher levels there are other emerging phenomena:

- This process is prone to overshooting the sugar egress, creating a "sugar crash", which has to lead to another sugar binge. This becomes an unhealthy see-saw. Note that the fat cells are consuming sugar but they can't release it back, they can only release fatty acids, hence sugar deficit must be replenished through food.

- The see-saw may end up messing the appetite and the balance of hormones that partake in regulating the metabolism. This yields the so-called "metabolic syndrome" with all its co-morbid factors: https://en.wikipedia.org/wiki/Metabolic_syndrome

- The hormonal imbalance changes the person's appetite, creating a vicious cycle.

Simple sugars are addictive. Just try going without to see how bad it can get - keep eating the fats, the meats, the complex carbs, just cut out the sugars, starches, and flours.

Exercise makes me ravenous, I'm certainly not the only person for which that is true. Swimming is the worst offender, IME. I can be vigilant, but even knowing that I didn't burn enough calories to counterbalance that meatball sub I want to get after my workout, doesn't help all that much in keeping me from actually buying it anyway. This is similar to the problem of calories in = calories out. Dieting isn't a chemist…

It's really important to stay hydrated, because your body often mistakes thirst for hunger. Drink water every 10m in the pool. Also, I often take a small amount of heavy protein immediately after the workout (~1/2 of one of those 33g protein bars is typical), then jump in the shower. Between these two habits, I've killed the post-swim binge. Hope it works for you too!

> Drink water every 10m in the pool

That means you'd need 5 drinks to complete just one length of an olympic-size swimming pool! :)

you can put your hunger to work for you, but you need to remind yourself that, if you carry extra pounds, hunger is what weight loss feels like. That ravenous feeling if you can keep it going, that right there is the success. celebrate it, and stop killing it.

No, it really isn't. I dropped 15kg with diet moderation over several months a couple of years ago, and I wasn't left feeling hungry apart from the first week (where I was adjusting to reducing the volume of my meals).

thank you. (i actually needed this advice, I experience this)

I went from 190 lbs. to 138 lbs. over 6 or 7 months. The only exercise I did was jogging for 45 min a day. What I noticed was that jogging made me feel better, which somehow got me to consistently eat better. After a days jogging I didn't want to put crap food in me and ruin what I had accomplished and by doing it everyday I felt good enough, often enough to stick with it. So, based on my experience, I simply can not…

To each his own.

Whenever I tried doing cardio exercises, I remember I would come back from the gym so hungry, I would eat a horse. And, I did. I couldn't stop -- I would eat whatever I could lay my hands on.

A couple of weeks later, my weight had in fact, increased. In my life, I have found I have been able to reduce weight only through two methods:

1. Strength training exercises + Protein (read meat) heavy diet 2. Small amount of vegetarian food three times a day

Muscle requires a lot of energy to maintain, so when your calories drop your body starts shedding it to be more efficient so long as you are also inactive . If you stay active you will lose strength on a calorie deficit but you will not lose muscle mass. That's why you can do a cut, and your lifts will go down but you still look great at the lower body fat. The muscle mass is still there. http://fitnessblackbook.com/…

Trained individual on a reasonable diet, taking an intelligent approach to cutting will lose 'some' strength and 'some' muscle when cutting body fat, yes. Someone who is out of shape might actually be able to gain both muscle and strength while losing weight when starting out as long as they are lifting in addition to cleaning up their diet/reducing calories. The less fit they are the better the gains, which I guess…

I wouldn't say it's captain obvious territory. I don't think most people realize how fast muscle development drops off after a year of serious training.
