2000 calories of protein def fends off hunger. If I know I'm going to be traveling all day, I load up on eggs for breakfast. It beats getting ripped off for crappy snacks at travel waypoints.

whole eggs have substantial fat, as a confounding factor in your analysis

I think OP's statement was cutting corners. Protein and fat both help you stay full for longer. Carbs/sugar do not. Even this statement cuts corners, but overall science supports the general sentiment.

You see this often with middle class city people in their late 20s and 30s. You go from being athletic in high school and walking all day in college to suddenly being in your prime dating age, regularly out eating and drinking with friends or dates, hitting 2-3 cocktails a few nights a week. You start investing more into your ultra-sedentary career, which you drive to, which constantly requires more of your time to g…

I don't think it's a s simple as inactivity. IF this were true, then being active would reverse the weight gains, but it does not, at least not for me and others. I was still as active in my 30s as I was in my late teens and 20s but still gained weight. Likewise, gyms are full of people in their 30s and 40s who are not losing weight despite regular attendance. Despite the popularity of fitness apps, people keep getti…

Nope, people eat too much first, and secondly don't move around enough.

On average man burns ca. 2500 kcal per day, mostly in rest. One hour of reasonably intensive cardio burns 500~600 kcal. If you have two such workouts a week it comes down to an increased energy use of 2*600/(7*2500) = 7%. Or a large meal. Just looking at the numbers it seems spending some time at the gym is not going to do much for loosing weight. Or said differently: eating 7% less is easier.

Of course cardio and strength training are useful for building/preserving muscle mass and general fitness. But for weight loss looking at food seems more effective.

I do wonder if this study is confusing, at some level, cause and effect. Yes, I definitely understand the argument that people blame things on "my slowing metabolism", but then don't seem to notice that the requirements of middle age (e.g. full time job and especially folks with kids) can make it harder to get exercise. At the same time, I don't have kids, and while I've stayed relatively active into middle age I've…

> takes me much longer to recover after strenuous exercise than it did when I was younger

The biggest difference I feel is proclivity to (small but reoccurring) injuries in certain weak spots...

This is from 2021 and was widely reported at the time. I see a lot of know-it-all comments, but the reality is they do not yet know why people gain weight in their middle age. No - the data doesn't show that it's merely due to being sedentary or changing diets.

If you want to reduce weight, then lower your caloric intake. You don’t even need to workout. Just measure your calories and keep decreasing them until the weight falls off. If you want to add in exercise, that’s great too, and then you can eat more calories. But if you studiously count calories and reduce them, you will lose weight - it’s guaranteed. If I put you on a desert island and starved you, you would lose we…

The problem with losing weight without exercising is that it's not only fat but also muscles that are lost.

Mostly bullshit as fat is the primary source for energy in the body and hard to earn protein are not. It's a myth mostly, do fast, do exercise, you will not lose muscle.

The article failed to mention another huge benefit of protein - it makes you feel full for longer. Eating 2000 calories of carbs is super easy. Eating 2000 calories of chicken breast is painfully hard.

> Eating 2000 calories of carbs is super easy.

Is it? That’s about 10 cups of cooked plain boiled rice.

I think carbs only hit the “easy to hit 2k” mark when it’s sugar (maybe?) or when it’s added with fat, especially fried foods.

> Eating 2000 calories of chicken breast is painfully hard.

I think this is about 7 cups of boiled, skinless breast of chicken.

I think this gets back to fat, or lack thereof.

For me personally, lean proteins don’t really fill me up — I have knocked back a pound of chicken breast with fresh veggies and I was hungry a few hours later. It’s mainly fats that do the trick for me for feeling sated — nuts, fat in meat, cheese, oil (esp. for roasting vegetables), etc.

Or two large milkshakes [1], or about 7 doughnuts or chocolate bars, such as Mars or Snickers, or about 500g of any random chocolate candies.

It's not a mystery, but it also sort of pretends that humans are robots. That is, the human body has developed homeostatic mechanisms over billions of years, and a big part of that is that if your body thinks it's starving, it will try its hardest to (a) make you hungry so that you will do whatever you can to eat more, and (b) slow your metabolic rate so you don't die.

The most productive way to lose weight is to cut out the soda, juice, cookies, ice cream, donuts, Captain Crunch, pie, cake, candy bars, pastries, etc.

Not the easiest thing to do, I know.
