Unsurprisingly, the title is sensationalist and not representative of the study. The study compares energy expenditure across different economic groups i.e. western people sitting in offices versus hunter-gatherers in Africa, and found that difference in energy expenditure does not account for differences in obesity, so points to consumption as the likely reason. The sample dataset explicitly excluded 'athletes', so…

Why unsurprisingly?

This is such a myth and I have no idea where it's coming from. Perhaps it's a nice lie one can tell himself to continue eating junk and not feel guilty about it.

I would say that in practice 99% of people can't outrun a bad diet, but not because of any sort of physiological reason. You simply need to train so much that most people won't ever approach the level of running/cycling/lifting they would need to do so. If you're training like an elite athlete (for me and my at the time roommate that was running 85, or in his case, 100+ miles a week with a few lift sessions) you can,…

> you can, and will, eat just about whatever you damn please and not gain weight

I don’t know if any athlete who can sustain themselves on a junk diet.

Not disagreeing but I think it's worth adding, "but you can outrun a slightly bad diet".

I once worked a night shift stocking job just after college. I was in phenomenal shape without hitting the gym. I was at my lowest weight with a ton of lean muscle as a result of moving heavy loads and stocking paint every night. I also did the math at one point, and given the size of the warehouse I was probably walking quickly 8 miles during my shift. It became a chore to eat enough calories every day. Somewhere around 4000 calories/day, you may still be hungry, but you are generally full. Also food sort of becomes boring, and the desire to eat just isn't as strong.

That said, it was 4-6 hours 4 nights a week. That is a lot of time to spend to burn all those calories. It is really not hard to eat an extra 100 calories per day, but it takes a lot of effort to burn an extra 100 calories. It's the asymmetry here you absolutely have to respect. Further, at least for me, there is another asymmetry in terms of satiation vs hunger. It is much easier to be slightly satiated than it is to be slightly hungry. What this means, is that there is a tendency to be driven to eat slightly more than your body needs. This is partly why the GLP-1 drugs seem so effective, is that they seem to flip this asymmetry in the other direction, which means weight loss is the default, instead of weight gain.

The chicken nugget thing is to avoid food poisoning though, right? It's because McDonald's food logistics results in hyper-consistent food irrespective of where you're at in the world and the last thing an Olympic competitor wants is to risk getting food poisoning from eating foreign food. I don't think Usain eats chicken nuggets on the reg.

I don't know the reason and think your reasoning is probably sound. Although at the same I wonder if chicken nuggets were really the only option? I'll make a grand assumption that most athletes weren't on the chicken nugget diet.

Chickens nuggets aren't necessarily that unhealthy even? They have about as much saturated fat as generic chicken thighs. Inherently food at Mcdonalds isn't that bad for you as long as you don't overeat and take a few supplements.

Whenever the topic of weight loss comes up, I always make the same recommendation: Lift weights. Lifting weights increases your muscle mass. Muscle burns calories, even at rest, which raises your TDEE. (A bodybuilder will burn more calories sitting on the couch than someone who doesn't lift weights). For most folks (myself included) cardio sucks. You _could_ jog for an hour every day and burn x-hundred calories due t…

I'm a fan of weightlifting, and agree that there are numerous health benefits to doing so, but I think the extra calorie burning is over-hyped. From what I've read you get 6-10 calories per pound of muscle per day, at rest. Not nothing, but for folks who aren't looking to body build I'm not sure it makes much of a difference. Or maybe over a long enough time span it does, I dunno.

I do bouldering and I eat fast food multiple times a week, I can definitely outclimb my poor diet... I probably helps that I don't eat breakfast though... It's well known though that as you build muscle, your rest calorie consumption increases, so probably if you build/maintain enough muscle, then you can just outrun your intake, since you consume more without doing anything to start with...

I eat fast food multiple times a week This doesn't mean anything. Just like improving your climbing, what matters is consistency. Count your calories and macros and you'll see that your total intake is reasonable. The processed vs unprocessed argument is negligible when you're only partaking occasionally. When I was younger, I couldn't understand why I was thinner than my friends. We'd go out to eat and I'd stuff dow…

> BMI isn't a useful metric

People these days are generally also significantly taller than malnourished Belgians were back in the 1840s. That skews it a bit since the formula itself is still the same.

I guess it's still a marginally useful metric in some case but now that when can accurately measure body fat, muscle weight etc. there is no point paying attention to it that much.

I think the current default knowledge you could expect a random average person to understand is limited to approximately the following single sentence: “A balance of diet and exercise is the key to losing weight.”

This is technically correct, but is so misleading that I classify it as incorrect.

That statement is exploitative of how the English language is understood, even if not intentionally so, that the lack of any other key points or instructions is itself used as contextual information.

In other words, the sentence likely translates something similar to the following incorrect statement: “A perfectly level 50-50 effort balance of both lowering daily calories to the [2000] calorie limit for [your demographic], because this is the stated necessary calories to support a healthy [demographic] for 1 day, as well as achieving the minimum daily recommended exercise limit of [1 hour for your demographic] plus [1 hour per 100 calories] consumed over [2000 calories] are both of equal value in the goal of losing weight, and are equal requirement to support the other such that one holds no value without the other.”

I think you'd still need to adjust your diet signifiantly. Most powerlifters don't look particularly in shape.

For people that are merely trying to lose weight, it's effectively true. When you're out of shape, you won't have the strength or endurance to exercise long and hard enough to actually burn significant calories.

For athletes that are running marathons or doing powerlifting, yes, it's certainly false. Massive bodybuilders that are already deadlifting hundreds of pounds will have massive diets because lifting that much weight takes significant energy.

But someone like me, with a BMI of 36, I can't outrun a bad diet. I go to the gym, set the treadmill at 5 mph, and I'm completely gassed after 3 minutes or 1/4 mile and have to slow down to 3 mph to recover. I'll go back and forth, but after about 20 minutes, I've gone about 1.3 miles, my legs are stiff and my ankles are sore because jogging at 240 lbs means high impact. Meanwhile, I've only burned probably ~100 calories. Not enough to offset the bad diet.

Given enough time of my routine, sure, my endurance might go up. Eventually I can do it longer, and maybe then I can start outrunning the bad diet. But that's going to take a long time.

Easier to just cut carbs.
