Appraising the brain's energy budget. In the average adult human, the brain represents about 2% of the body weight. Remarkably, despite its relatively small size, the brain accounts for about 20% of the oxygen and, hence, calories consumed by the body (1). This high rate of metabolism is remarkably constant despite widely varying mental and motoric activity (2).
Determine your goal body fat percentage. Women who are healthy but not athletic, called average by the American Council on Exercise, have 25 to 31 percent body fat, and healthy, non-athletic men have 18 to 24 percent body fat. For women, a body fat percentage above 32 percent is considered obese. In men, 25 percent or more body fat is considered obese.
