Weight Gain Strategies

1. Increase Caloric Intake

The most important factor in gaining weight is consuming more calories than you burn. This means increasing your overall intake of food and beverages. Aim to consume an additional 500-1000 calories per day, depending on your current weight and activity level.

2. Focus on Nutrient-Dense Foods

Not all calories are created equal. When trying to gain weight, it’s important to focus on nutrient-dense foods that provide a variety of vitamins and minerals your body needs. Examples include:


Protein is essential for building and repairing muscle tissue. Aim to consume 1-1.5 grams of protein per pound of body weight per day. Good sources of protein include:

  • Lean meats (chicken, turkey, beef)
  • Fish and seafood
  • Eggs
  • Dairy (milk, yogurt, cheese)
  • Lentils and beans
  • Nuts and seeds


Carbohydrates provide energy for your body and should make up a significant portion of your caloric intake. Good sources of carbohydrates include:

  • Whole grains (brown rice, quinoa, whole wheat bread)
  • Fruits
  • Starchy vegetables (potatoes, sweet potatoes)
  • Legumes (beans, lentils)


Fats are important for overall health and can also help you gain weight. Good sources of healthy fats include:

  • Nuts and seeds
  • Oils (olive oil, coconut oil)
  • Avocado
  • Fatty fish (salmon, tuna)

3. Eat More Frequently

Eating more frequently can help you consume more calories throughout the day. Aim to eat every 2-3 hours, and include snacks between meals. This can also help prevent feelings of fullness and make it easier to consume more food overall.

4. Incorporate Strength Training

Strength training can help build muscle mass, which can contribute to healthy weight gain. Aim to perform strength-training exercises 2-3 times per week, targeting all major muscle groups. Examples of strength-training exercises include:

  • Squats
  • Deadlifts
  • Bench press
  • Shoulder press

5. Avoid Skipping Meals

Skipping meals can make it more difficult to consume enough calories throughout the day. Make sure to eat breakfast, lunch, and dinner, and include snacks in between meals to meet your caloric needs.

6. Drink Caloric Beverages

Drinking caloric beverages can be an easy way to consume more calories. Examples include:

  • Smoothies
  • Milkshakes
  • Juice
  • Sports drinks

7. Prioritize Sleep and Reduce Stress

Chronic stress and poor sleep can interfere with healthy weight gain. Make sure to prioritize sleep and implement stress-reduction techniques such as meditation and deep breathing.
