Which dietary choice best complements physical activity in maintaining a healthy body composition?

The choice of a low-fat diet can be beneficial in complementing physical activity for maintaining a healthy body composition because it often emphasizes whole foods, including fruits, vegetables, lean proteins, and whole grains. When paired with regular physical activity, this type of diet can help promote fat loss while still providing essential nutrients needed for energy and recovery. A low-fat diet may assist in reducing overall caloric intake, which can lead to weight management while supporting active lifestyles.

Incorporating a variety of low-fat foods can provide the necessary macronutrients and vitamins while minimizing excess calorie consumption that can lead to weight gain. It also aligns with the goals of many physical activity programs aiming to improve endurance and strength without adding excess body fat.

Other options like a vegetarian diet, drinking water, and a low sodium diet each play unique roles in a healthy lifestyle but may not directly address the importance of macronutrient distribution in relation to body composition as effectively as a low-fat diet. For instance, while hydration is crucial, it does not directly affect how body composition is achieved through dietary choices in conjunction with exercise.
