Yeah, lately I really feel a difference between eating warm and cold stuff. Before I didn't really notice.
It's not even a warm/cold food thing, it's more like you're low on energy so your body isn't producing as much heat as usual. When it happens to me it's usually before lunch.

I expected that to be the cause, but me eating cold yoghurt to replenish my energy or me eating a hot sandwich makes a big difference, I now notice.
This is known as specific dynamic action, or the thermic effect of food. Your metabolism does actually increase as a result of eating.
