Some friends and I are currently doing a thru hike of the Appalachian Trail, and only ten days in the four of us clocked 7, 8, 10, and 17 pounds lost... But we're hiking 6+ hours a day with heavy packs. We've been eating easily ~3000kcal each daily. I think at the extreme edges, nutrition science is a lot less well understood. We were very surprised to see we'd lost anything at all, as we're stopping to eat 300 calor…
> “You can’t exercise your way out of obesity,” […] “you can’t outrun a bad diet.” While this article is being a bit dramatic and possibly understating the impact of exercise slightly, I feel a little dumb that I didn’t know this earlier. It took me several decades too long to understand the obvious, that exercise is for building strength, and losing weight happens by eating less. I tried for way too many years to ex…
I think a big part of the issue is that popular fitness and weight loss advice has perpetuated the wrong way to exercise to loose weight. When most people think about exercise for weight loss, they imagine long exhausting sessions on the treadmill, dripping with sweat, and a high calorie burn number. While the short term results may seem great based on the immediate calories burned, it's actually a terrible strategy…
This is a major education/communication issue. When I switched to weightlifting, I started seeing rapid and significant results. And I don't even really sweat from it (except on leg day)

>A lot of people know this already, so it’s not busting everyone’s myths It is still worth mentioning - because it is so easy to overlook. Some simple math: if I go all out on a row machine for 30 minutes, I'll burn 300 calories. If I eat 2 extra slices of pizza, it is easiely 300 calories If I swap a turkey sandwich with healthy options, I can reduce my linch calories by 300 - and I can save even more during dinner…
A few hours on my bike can be 2,000-3,000 additional calories over base metabolic rate. That's not based on made-up calories but actual work from a power meter on the bike. "You can't exercise your way out of a bad diet" - literally not true for a fuckton of endurance-sport athletes for whom the challenge is eating enough calories. It's 100% true for people who think exercising for 30 min means license to eat whateve…
Hello old friend, we meet again.

Riding a bicycle? It's roughly 5x more efficient than running or walking. If you want to lose weight from cycling, you're going to have ride significantly further than 50 miles a day.
It has very little to do with distance. I lose weight much faster with hiit than riding long distance.

> Combining this with the fact that Everest climbers are apparently eating 10K+ calories a day and then up to around 20K on summit day, I have to wonder how these facts jive...if they can really temporarily push the limit, for how long, etc. I think a lot of these stats are myths meant to accentuate the difficulty of the task. Pontzer’s book discusses Michael Phelps and the lack of an actual source to the rumours he…

Not sure what was your starting weight. But 5 kg is within the realm of normal weight fluctuations over a week for an average American.
Are you sure, I get a one or two kg swing, but 5kg of weight seems a bit extreme. I'm not American, but in my part of the world people tend to have gradual trends to weight, not sudden swings.

This is purely anecdotal, with a sample size of one even if it is right, but it seems to me, personally, that exercise suppresses my appetite to some extent. I can't say that this is even real, but if it is, my best guess as to why this might be is that the exercise subtly stimulates/irritates my gut such that I am de-motivated to eat, either by feeling full or subliminally 'sick to my stomach'. After running a marat…
This is my experience as well. I also had a trainer confirm this.
I used to eat before and after a workout because I bought into the idea of the body needing fuel to power the workout and fuel to recover. I ended up eating when I wasn’t hungry and feeling heavy or sluggish.
She said the appetite suppression after a workout could last 30-120min and to only eat when I felt hungry. I felt much better after adjusting my eating habits.

I think everyone is talking past each other here. From the article: > As the athletes’ ran more and more over weeks or months, their metabolic engines cut back elsewhere to make room for the extra exercise costs You clearly burn extra calories when exercising, but the thesis of the article is that it doesn't matter in terms of weight loss because your body will adjust to burn the mean level of calories. The obvious e…
This is well known and true even if the claims made better happened to be entirely false. I’m not dismissing your point, here. I agree fully.
Exercise just doesn’t burn enough calories to really matter. Especially in the face of a poor diet. Running burns ~100 calories per mile (yes, varying based on weight and a little bit based on speed but it’s a close enough rule). A can of soda has ~150 calories. There’s just no competition. Someone trying to lose weight can skip a soda or a candy bar and it’s more effective than running an extra mile.
