Weight Gain Diet

If you're trying to gain weight, whether it's because you're underweight or simply want to gain muscle mass, a healthy weight gain diet will help you meet your goals. Making a few simple dietary changes and following a weight gain meal plan will get you the results you need in no time, especially if you're working out regularly.

Calorie Goals

To achieve a healthy rate of weight gain, aim to eat 500 more calories than your usual daily intake. This calorie increase will help you gain a half to one pound per week. To help you avoid feeling bloated or uncomfortable after meals, space out the extra calories evenly throughout the day.

When to Eat

While it may be ironic that the same eating pattern works for weight loss, eating frequent meals throughout the day is also recommended for healthy weight gain. The Academy of Nutrition and Dietetics and Mayo Clinic recommend eating five to six times daily to pack on pounds. Eat every few hours. For example, you could have meals or snacks at the following times:

  • 8:00 am
  • 10:30 am
  • 1:00 pm
  • 3:30 pm
  • 6:00 pm
  • 8:30 pm.

The following healthy, high-calorie foods are beneficial when you're trying to pack on pounds:

  • Nuts
  • Nut butter
  • Seeds
  • Cheese
  • Milk
  • Hummus
  • Avocadoes
  • Plant-based oils
  • Dried fruit
  • Juices
  • Starchy vegetables (peas, corn, potatoes, and winter squash)

Exercise Tips

When you're trying to add mass, exercise is a must to gain muscle instead of just body fat. Resistance exercise in particular is beneficial, according to the American Academy of Family Physicians. You can continue to do cardiovascular exercise as well, but in shorter durations. The McKinley Health Center suggests engaging in two to three 20- to 30-minute cardiovascular workouts weekly and completing two to three sets of four to eight weightlifting repetitions for each exercise (working all major muscle groups) to maximize strength and muscle gains.

Bottom Line

Getting extra calories from nutrient-dense foods throughout the day and regular strength training are the keys to healthy weight gain.
