Overview
If you’re naturally skinny and struggle to gain weight, you’re not alone. Some people have a high metabolism, smaller appetites, or simply burn more calories than they consume. Gaining healthy weight requires more than just eating junk food it’s about building lean muscle mass with the help of nutrient-dense, high-calorie foods.
This guide explains how to create a safe, effective high-calorie diet plan designed to help you bulk up the right way.
How Weight Gain Works
To gain weight, you need to consume more calories than your body burns in a day a state known as a caloric surplus.
-
Maintenance Calories: The number of calories your body needs to maintain its current weight.
-
Surplus Range: For bulking, aim for 300–500 extra calories per day.
Note: Too much surplus can lead to fat gain instead of muscle.
