Overview

A weight gain diet is designed for individuals who are underweight or want to increase muscle mass. The goal is to create a positive energy balance by consuming more calories than expended. However, this does not mean overeating unhealthy foods; consumption of nutrient-dense, calorie-dense foods is important.

Key Benefits

  • Supports healthy weight gain.
  • May help increase muscle mass (in conjunction with resistance training).
  • May increase energy levels.
  • May help address nutrient deficiencies.

What is it?

A weight gain diet aims to increase daily calorie intake to be greater than what the body burns. This is typically done by increasing meal portions, adding snacks, and choosing calorie-dense yet nutritious foods.

Who is it for?

It is implemented for individuals who are below their ideal weight, experience loss of appetite, have a fast metabolism, or athletes who want to increase muscle mass, to gain weight healthily.

Foods to Enjoy

  • Nuts and seeds (almonds, walnuts, peanut butter, sunflower seeds)
