There has been quite a lot of new, exciting and actually useful science in recent years about how to have a healthy body, but I think most people only look at calories. Some may look at fat/carbs. And some may also look into excercise as well. But in order to have a healthy body long term it seams you need to look into all of that, and sleep quality, and mindfullness/stress control.

That may sound like a lot, but each piece helps you out a little to keep the other pieces in check. Having a full night of sleep keeps your impulses in check. Excercise helps you sleep, keep muscle mass and fat at desirable levels. Eating healthy makes sleep easier etc. And they reinforce each other.

So keeping yourself in this healthy steady state is actually quite easy, as long as you take a holistic apriach and not over specialize in each area.

This is a hunch of mine though I havent really found any studies that take all of those things into account, just the specific interactions between those things.
