AI: Evolutionary anthropologist Dr. Hermann Pontzer argues that exercise may not be an effective way to lose weight because the body adapts and reduces energy use in other areas. However, exercise can have health benefits because it diverts excess energy from potentially harmful processes in the body, such as inflammation and stress. Research shows that a person cannot exceed their metabolic budget, and exercise changes the way energy is used, not how much energy is used. Additionally, research from the Hadza group shows that even vigorous movement does not significantly increase calorie burning. This may be because the body strives to maintain the same frame of limited energy, which includes various activities such as immunity and stress response. Thus, exercise can be beneficial to health because it allows the body to expend excess energy, keeping the immune system and stress responses in balance.
