When you jog, most of the food energy you burn above your basal metabolic rate (BMR) ends up as internal energy that would raise your body temperature if it were not eliminated. The evaporation of perspiration is the primary mechanism for eliminating this energy. Determine the amount of water you lose to evaporation when running for 46 minutes at a rate that uses 400 kcal/h above your BMR. (That amount is often considered to be the "maximum fat-burning" energy output....

Suppose an individual wants to lose 10 pounds (about 5 kg). The person’s weight has been steady for over a year with well established eating and exercise patterns. In this problem, you will model how different choices affect the weight loss. (a) What can you infer about caloric intake versus caloric use for this person from the problem statement? (b) Suppose the person makes a few changes that result in consuming 10% fewer kilocalories every day, going from 2,400 kcal/day...
