Energy balance is the state in which the number of calories eaten equals the number of calories used. This balance is affected by physical activity, body size, amount of body fat and muscle, and genetics.
Steering our calorie intake to lose, maintain, or gain weight together with measuring appropriate protein, carbohydrate, and fat intake is essential to optimizing our lifestyle, nutrition, and training.
Lifestyle is about healthy habits and daily rituals. Nutrition is about losing fat, supporting lean mass or maintaining weight.
Training is primarily how we gain, maintain muscle mass and improve our body's potential. Learn the difference and succeed.
