On the combat side I always tell my trainees it's ok to have an enormous muscle mass, I do have a decent one after all, but never, ever try to get rid of all your fat because as soon as you get out of supplies or a bit too far from your lines you'll be likely to literately run out of energy about a dozen hour after your last meal in a combat scenario. Adrenaline can't propel anyone on its own.
I put some of the teams I trained through an intense food less training over three days, got half of the team, the gym nuts, failing said test.
Usually after that they got their lesson.
