Step 1: Personal Details
Understanding Healthy Weight Gain
A healthy weight gain is typically 0.25-0.5 kg per week. Gaining weight too quickly can lead to excessive fat accumulation rather than muscle growth.
Step 2: Nutrition & Activity
About Calorie Surplus
A calorie surplus of 500 kcal/day typically leads to approximately 0.5 kg weight gain per week. Muscle gain requires proper nutrition and strength training alongside the calorie surplus.
