Understanding Weight Gain
Calorie Surplus Explained
Weight gain occurs when calorie intake exceeds calorie expenditure. A surplus of 3,500 calories equals approximately 1 pound of weight gain.
Healthy Surplus Levels
For healthy weight gain, aim for a surplus of 250-500 calories per day. This promotes muscle growth while minimizing fat gain.
Protein for Muscle Growth
Consume 1.6-2.2 grams of protein per kilogram of body weight daily to support muscle growth. Strength training is essential for converting calories to muscle.
Nutrient Timing
Distribute calories evenly throughout the day, with adequate protein at each meal. Post-workout nutrition supports muscle recovery and growth.
