More anecdata, but I find it depends on the type of exercise. An hour of cardio equals several hours of appetite suppression. An hour of heavy weight training equals several hours of unstoppable hunger. What I eat in that state (high carb, low carb, whey protein, etc) doesn't seem to affect satiety much.

I believe this could be the main reason why its almost impossible to eat at a caloric defecit (with surplus protein) and train anabolically at the same time. Some people are able to do that, it's just very rare.

I experience the same effect. Cardio doesn’t make me hungry afterwards, in fact I tend to be less hungrier than I was before I started the workout.

Heavy weights induces a deep visceral hunger that I can only describe as the hunger that you feel when your body is depleted and is starting to burn fat stores. It’s different to the usual hunger pangs. Anyone else felt it? It makes me double over sometimes and I completely lose track of what I was doing whenever I get those pangs. I almost always follow up with a heavy meal.

Yes, same here. It's not just "I'm hungry". It's more "I cannot think about anything other than food".

I'm not sure it has anything to do with burning fat stores though, because I don't get the same feeling after say, a 3-day water fast. At that point I'm definitely hungry, but don't have the same insatiable food craving.

In fact, when I was experimenting with extended fasting, the only reason I stopped at 3 days is because I was lifting lighter weights every day and hit a point where my strength was physically depleted. I could only do about 3 reps instead of finding 15+ easy. Hunger wasn't really a problem after the first day of getting used to it.
