Study finds intense exercise may suppress appetite in healthy humans

I’m not sure what’s behind this, could be endorphins, adrenaline, or something else entirely-- but I wonder if it’s related to that “runner’s high”. The first time I ran a 20-miler on a Sunday, about 3 hours of steady, low-key cardio, I went through an entire box of pasta afterwards and still felt like I needed more food right after. Now, after doing it 20+ times, I don’t even feel extra hunger kick in after the workout.

On days when I wake up and do something intense, like 4x1K repeats or 2x2-mile threshold sets, I feel electric afterwards, but at at the same time thinking about food makes me slightly nauseous. I’m not even close to hungry for hours, which throws off my eating for the rest of the day.

But then there’s carryover calorie deficit. Let's say the next day I wake up for an easy day with a 5-8 miler, I’m sold on breakfast right afterwards, and I can usually eat any amount that's in front of me.

I've experienced this as I've ramped up my morning workouts. I often don't get hungry until lunch.

Same here. When I was into running, I never really ate much when I got back unless it was some big race. Unfortunately injured now :(

Same! I pulled a tendon in my ankle.

The military has worried about lean mass loss in intense training--ranger training, SEAL training, etc. At one point, the National Academy of Sciences did a book on this, of which I recall only the words "exercise-induced anorexia." A search on the press website yields nothing in particular, though.

For intense morning training I always had a small bowl of oatmeal (straight, non salted or sugared) and milk half an hour before, and two very strong coffees right after (before sauna cooldown), then some lean meat, chicken filets or steak as lunch.

When you are in peak form, you actually feel the effects of nutrients in your body very intensely.

I wish I could do that. I have to train fasted in the morning because it feels like my body is processing the food (even plain oatmeal) and taking away from performance. I'll try the coffee before sauna idea tomorrow though - never thought of that order...

Probably also depends on timing and the type of training.

I started with 1 hour of extremely intense cardio. The first 40 minutes you can go through before the sugars from the oatmeal start to hit, but starting around that 40 minute mark, the real burning of your body stored energy starts to kick in and you can realy feel those flows. The next 30-60 minutes I did high rep but relatively low intensity strenght training. This is what the oatmeal was for.

The idea of the high caffeine shots right after training just before the sauna was a hack to make you want the training more. You mentaly fuse the caffeine addiction reward into the workout routine so your brain craves the workout.

I find that, while exercise reduces my own appetite temporarily, it ramps it up later.

Last sentence I read of that article

Thanks for acknowledging you didn't read it, I guess? Why comment?
