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 marathon without proper training, it was a couple of days before I felt like eating anything.

I am not intending to dispute the fact that you ate more to compensate - you say you did, and I don't doubt it. Nor am I doubting that weight gain is a function of net caloric intake; it is just a suggestion of another way exercise may affect this.

FWIW most of my exercise is running, hiking or kayaking. I am not sure (or perhaps that should be 'even more doubtful') that kayaking has the same effect.

You’re so lucky! I wish exercise made me less hungry. I’ve only felt that when going on very long multi-day hikes… being in severe calorie deficit and having almost nothing sound good to eat. Chocolate was one of the only things that I could stomach. Oh and once I went running about an hour after eating tomato soup, and halfway through starting heaving uncontrollably. But normally, running, gym time, weight lifting and biking all make me hungry. :P

There’s no doubt that appetite and everything around dieting and weight loss has a huge range of variation in behavior and what works. In addition to learning to separate exercise from food, the other thing that took me too long to learn is that weight loss is more mental exercise than physical. Figuring out how to trick myself into calorie tracking and habit forming isn’t easy, and my tricks on myself clearly don’t work for everyone.

For me I lose my appetite for about a half hour, I was taught it's simply blood from your stomach being used elsewhere. After a short recovery period I'm definitely extra hungry.

I used this however to cut one meal per day. I'd eat breakfast late, a bit before regular lunch time, and then get hungry leaving work. Riding the bike home made the hunger go away, and it stayed away for about half an hour, enough time to cook dinner.

The result was that I wasn't superhungry when I started eating. I also tried to eat high protein, high fiber meals so I'd stay full for longer.

Intermittent fasting can help repair a lot of things in your body, make you live longer, etc.

Vegans live on average 10 year longer!

The hunger you feel the first day btw is not "real" hunger, it's just your stomach growling and you being used to eat. After you ignore hunger for 3 days, your body stops wanting food. That's if you want to do a cleanse. (I've never done one though)

Short fasting has been shown to have positive health effects when done right. Even short fasting can be dangerous and should absolutely not be done without prior consultation of a medical professional.

That being said 'clesnding' has been disproven scientifically so many times, I think there must be a Necromancer for bad nutritional myths out there. I just can't understand why this myth (together with others) always comes back from the grave.

Regarding vegans. Yes a primarily plant-based diet has been shown in studies to be beneficial to health. Depending on the environment of the test subjects. For practical purposes in western/northern societies that holds true.

The important word is plant based. Because without either taking extreme care of the (especially) micro nutrients as a vegan you either need to substitute or be extra cautious. And of omnivores with a primarily plant based diet also look at their nutritional balance, caloric intake and such, the difference between diets in the studied groups vanished.

So one could say if eating primarily plant based and being mindful of our diet and nutritional needs, there is no difference scientifically.

The only remaining difference is one of personal values and believes. The question of how (or if) do we want to have animals treated to firm our diet. Personally I would add to look at how do we want the humans in the food production chain treated as well and how do we want our diets to have an ecological impact.

But as said - these are existential because deeply personal value questions that can't be scientifically discussed.

Is it known if the meat causes people to die sooner, or is it just that people who are vegan are correlated with people who care about their health so they do other things that cause the 10 year effect?

I feel like a non-lethal poison like a flea killer or something would cause a 10 year lifespan drop, so it would be surprising if meat were as deadly as flea killer poison.

Re:Scientist busts myths about how humans burn calories by fredophile on Friday February 18, 2022 @01:06AM (#30382602)
I'd guess the lack of processed foods is a big part of it. Until recently if you were vegan you pretty much had to make everything from scratch. I'd also guess that the average vegan is more health conscious than the average meat eater.

When compared with the SAD standard american diet, any diet intervention (short of eating double portions of the SAD) is going yield positive results.

I hear this is a very dangerous game if taken to an extreme. You have to be very disciplined once you take it beyond 3 days. David Blaine did it for 44 days and I believe he has liver damage now? He talks about it on Joe Rogan.

Professional athletes cut for several days quite often. It’s well researched area.

But better way for regular people is just do OMAD. You get used to it after first three days, which are brutal. So, strong motivation is required, but still easier than real cut for bodybuilders or fighters.

Interesting if it's actually true. I doubt there are any good studies about that, though.

> exercise suppresses my appetite to some extent

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 feel like from reading through this thread is that everyone has a body that manages hunger and metabolism differently.

Pretty sure this is the same for me, I don't eat before the gym in the morning and if anything feel slightly less like eating after.

From what I've seen and experienced the act of exercising suppresses my appetite. I can't eat a big meal and immediately work out. If I'm a little hungry a few minutes into working out I'm not. But hours later or the next day I'm famished and will eat more. It's like a different kind of hungry--more of a craving.

I think moderate exercise can help with getting used to not over-eating. More strenuous exercise seems to make the body crave larger meals often negating any calories burned.

For me exercise does suppress the urge to eat sugary things. I don't know if it's subconscious or just how my body reacts but on days when I have good exercise, especially long runs I feel less urge to have sugars and more urge to eat chicken, cheese etc.

It doesn't really suppress the urge to eat though. Unfortunately I had to learn the hard way that I must count my calories, I have been counting them for 15+ years now and it has become part of my life.

some would argue that running a marathon isn't exercise and shouldn't be considered as such.

Whether any one in particular subscribed to that school of though or not, marathon running is an outlier event, and isn't what most people would consider as part of a regular, healthy, exercise regime that one might do many times a week.

Re:Scientist busts myths about how humans burn calories by mannykannot on Friday February 18, 2022 @07:29AM (#30384887)
To be clear: I only mentioned that marathon because it was a particularly clear case of the effect exercise seems to have on my appetite, and I am not recommending it as an exercise regimen.

And while it is not for most people (and definitely not me), there are people I know who thrive on running marathons and the training for it, while otherwise living perfectly normal lives. There is a hypothesis that cursorial / persistence / endurance hunting was a a stage in our ancestors' evolution, and that we have inherited some of the traits of that lifestyle.

That's a POV, and you could marshall evidence to defend it.

But it's mostly a hand-wavy assertion too, and there's other evidence against it. There are cultures around the world (low populations, to be sure) where repeatedly traversing 26.2 miles a day would not be considered particularly abnormal.

Re:Scientist busts myths about how humans burn calories by watwut on Friday February 18, 2022 @02:03AM (#30382912)
There is no culture in a world that would consider it normal to run 26.2 miles with no breaks. Walking it in a span of a day is massively different. Anyone who does hiking can do it. The same people however can not run that distance.

Even marathon runners run marathons only on competitions. The chance of injury or sickness after is too high in order to make it worthy. And after, you are supposed to rest for multiple days even if not injured. Again, 26.2 miles is 8 hours of hiking and you are pretty much guaranteed to be ok after it.
