Why do women burn fewer calories than men?

Women's bodies are built differently than men's -- women have more fat and less muscle. Less lean body mass means they have lower resting metabolic rates compared with men. Women burn fewer calories on a baseline level. That smaller body size means women burn fewer calories with the same amount of exercise. Also, women's bodies have evolved to hold on to fat stores better in order to produce and nourish healthy babies.
