> if you're optimizing for weight loss and you find yourself hungrier when you exercise, you're likely going to find yourself hungrier when your caloric needs increase in general What I'm observing is that with a cardio session there's an increased craving for food in that moment that is quite intense. While in both cases (weight training and cardio) there is a need for additional energy, its easier to manage through…

> A deficit of about 4000 calories a week is healthy for a loss of about a pound. There isn't really a hard and fast rule here, it depends on the person. If you are obese enough, you can engage in an extended fast with no food whatsoever (just water, vitamins and electrolytes) and lose up to a pound per day in ketosis. But obviously that should only be done with the supervision of a doctor.

That is true. Ideally one would shoot for change that is healthy and sustainable.

> I don't know many 30-somethings (especially in tech) that can work out for a half hour uninterrupted, nevermind an hour. I work full-time in tech, have a wife, two kids, two dogs, and work on my book [1] writing every single day. I still definitely have 30 minutes of free time every day to work out. What I don't have as much of is will-power/discipline/execute function whatever you want to call it. I workout twice…

Kudos on the book. I have two myself (one with Wrox and one with O'Reilly). It's a lot of work and you should be proud. I didn't say I couldn't find an hour just that most people in their 30s I know in tech can't. You also lowered the requirement from the hour the author and I said to a half hour. Keep in mind too unless you want to sit in sweat all day that hour does not include changing cloths and showering. I also…

Yeah, I had all of your qualifiers in mind. I can definitely reliably find 30 minutes or even an hour of uninterrupted time. It's not always at the same time, but I can find it if I gotta.

I think most people can. What's harder is summoning the willpower to use that hour effectively.

You call this "data driven"? Look at his explanation of the supplements he takes: >Grenade Thermo Detonator: A scary name, but essentially a dosage of caffeine from concentrated green tea extract that's meant to be a fat-burner/pre-workout pill. It gives you some energy to focus, and suppresses your appetite. It is not very different from simply taking a packet of coffee. I used these for the first 4 months. >Multivi…

We do not really need as much protein as the supplements industry would have us believe.

Nice job and all but the sheer amount of shirtless photos at different angles just shows how narcissistic you are.

He's proud of what he's accomplished, in a weightloss post-mortem. How does that make him narcissistic?

Look at the number of photos and angles this guy has of himself on the page. We've all seen before / after photos of people who've lost weight. I've never seen this many photos of one dude. It's super narcissistic.

Don't let the fact that he was 24 deter you. Over at r/bodyweightfitness, there are hundreds of people who started above 45 and are in better shapes than 20 year olds. Obesity is now a taboo topic in tech because you might unfortunately step on the toes of a few sensitive people and be labelled a fat shamer. This is not the case.Obesity in tech is a disease on it's own and it needs to be fought with a sharp edged pit…

"Sustainable weight loss is achievable by everyone, whether you're 40 or 50 years or 400 pounds or 600 pounds." While I applaud those individuals that have kept off weight long term, the science disagrees that is an achievable goal for everyone.(only about 5% of people who successfully lose large amounts of weight will keep it off long term) For example here is what happened to the contestants on the biggest loser. h…

From my understanding, they dropped body weight very quickly, not allowing their body to adjust to new eating and exercise habits. They (seem) to go to extremes -- either all or nothing.

I don't buy into your endocrine/metabolic system theory whatsoever. Do you have any evidence that this is even possible?

Hi. Neuroendocrinologist here. Body fat is regulated by specialized circuits in the hypothalamus. We now know that inflammation of these central nuclei is a key feature of weight gain in both animals and humans. There are two sets of neurons: those that promote feeding and slow metabolic rate, and those that suppress feeding and increase metabolic rate. The former class of neurons is GABAergic (inhibitory in neurosci…

Sure but that's all still about 'overeating' and 'hunger' (you feed a mice high fat foods, it triggers overeating)?

So it's still the case that if you keep your calorie intake below your TDEE, you won't regain the weight, whereas a lot of weight re-gainers like GGP claim some vague 'endocrine/metabolic' thing, when we have no evidence for that.

Have you read The Power of Habit?

The focus on willpower is almost inherently demoralizing and absolutely not the best strategy. You should focus on building habits, even one at a time, so that you can let the habits take over without expending much in the way of willpower.

The building of habits is what takes energy, but once they've been built, they almost run on autopilot.

And on a different note, there's a difference between exercise and training. Training for a goal can be a much more productive use of your time and will probably get you better results in terms of fitness and body composition depending on the goal chosen.

If he is super narcissistic, what does that make all the actresses and actors strutting the stages of public shows with a buttload of face paint, hair dyes, plastic surgeries and the like?

Or is it that you casually use the word 'narcissistic' only when disapproving of something you don't like?

Do you have any sources for the 5%? More often than not, the cause of the weight gain is because they fall back to bad eating habits. If you can lose it, you can keep it off. Changing to long-term good habits is extremely difficult though.

http://m.ajcn.nutrition.org/content/82/1/222S.full

Here's one that mentions 20%. But that's at a year. The % changes depending on how long you follow up(drops all the way out to 5 years.). This is study uses keeping off 10% of body weight as the definition of success which is far less than the amount that it takes to move an individual from obese into the normal healthy range.

If you can find a study where a majority of the individuals experienced significant and long term(3 yrs+) weight loss I would be happy to see it.
