A man decides to lose weight by dieting and exercising. He chooses to reduce his caloric intake by 500 calories a day, and he lifts weights daily as his main form of exercise. After strictly following his diet and exercise plan for two weeks, he finds that even though his waist has shrunk by two inches, he has actually gained weight. The man hypothesizes that his caloric intake is still too high. What might be another possible hypothesis?
