Lucy and Marcy are sorority sisters whose heights, weights, and ages are almost exactly the same. Lucy is studying engineering and walks several times a week for exercise. Marcy is an exercise physiology major who aspires to be a professional tennis player, and runs marathons as a hobby. How would you expect their healthful diets to differ?

Question

Quizplus · Accepted Answer

Marcy's intense exercise regimen (running marathons and aspiring to be a professional tennis player) requires a higher energy intake, and carbohydrates are the primary source of energy for endurance activities like running and playing tennis. Therefore, Marcy would need more calories and more carbohydrates in her diet compared to Lucy, who walks for exercise and doesn't have the same energy demands.
