That's a really good point. The majority of the calories people burn is down to maintaining their internal temperature and keeping them alive. Only 8-10% of calories are used in the form of exercise. The basal metabolic rate will naturally reduce, however, to starve to death does take more than 40 days. The main reason people die before they reach that date is because they lose moral and things like that. That releases cortisol and other dangerous hormones that degrade your body much faster. It's as you said TL, the weaker the body, the faster you break down. If a person is able to maintain higher spirits, they are capable of living much longer than a negative person in the same situation. Remember that guy in the car that survived on snow? That was like 34 days or something, and that's just on snow. No calories in water.
