Nutrition and exercise interact in weight management by creating a synergistic effect on caloric balance. Proper nutrition provides the necessary fuel for workouts and recovery, while exercise helps to regulate body weight and maintain muscle mass. A well-balanced diet supports performance enhancement, energy levels, and metabolic health, making it easier to achieve weight loss or maintenance goals. Moreover, consuming the right nutrients post-workout can facilitate recovery and muscle repair. Thus, an integrated approach that includes both nutrition and exercise is essential for effective weight management.
