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)
  • Avocado
  • Full-fat milk, yogurt, cheese
  • Red meat, oily fish (salmon), chicken (thigh parts)
  • Whole grains (oats, brown rice, whole wheat bread/pasta)
  • Dried fruits (dates, apricots, raisins)
  • Potatoes, sweet potatoes
  • Olive oil, coconut oil
  • Smoothies (with fruit, vegetables, protein powder, milk/yogurt, nut butter)

Foods to Limit

  • Low-calorie "diet" products
  • Excessive amounts of processed, low-nutrient junk food (would contribute to unhealthy weight gain)
  • Sugary sodas (can create a feeling of fullness and hinder nutritious food intake)
  • Drinking too much water or calorie-free drinks right before meals (can suppress appetite)

Core Rules

  • Eat regularly, 3 main meals and 2-3 snacks per day.
  • Choose calorie-dense yet nutritious foods.
  • Gradually increase your portion sizes.
  • Utilize liquid calories (like healthy smoothies).
  • If you want to gain muscle mass, do resistance training.
