Gaining weight in a healthy way means focusing on nutrient-dense foods while ensuring you get enough calories. Here are some practical tips to help you reach your goals while keeping your diet balanced.
Why Dietary Fat is Your Friend
Fat is the most calorie-dense nutrient, providing 9 calories per gram, while protein and carbs each contain 4 calories per gram. To gain one pound, you need an extra 3,500 calories, which translates to about 500 extra calories per day for a week.
Best Fat Sources for Healthy Weight Gain
- Animal Fats: Butter, cheese, eggs, fish, meats, full-fat dairy
- Plant Fats: Nuts, seeds, olive oil, coconut oil, avocados
Example of Calculating Estimated Calorie Needs
Let’s say you are 5’11” and 155 lbs. Your baseline calorie burn is about 1,400 kcal/day (before exercise). With activity, you're likely burning around 1,650 kcal/day.
To support weight gain, aim to add 500 extra calories per day, bringing your total intake to about 2,200 kcal/day. While calorie tracking may be helpful down the road, for now, let’s focus on simple, high-calorie additions to your meals.

Boosting Your Protein Shake (From 160 to 500 Calories)
Already have protein shakes at home? Premier Protein, glucerna, Fairlife, and many others are common ones people seek in order to get nutrition. However, they are highly processed, and lack calories and fiber, so they don't often help with weight gain or gut health. A great way to increase your daily calories is by enhancing your protein shakes. Using a blender (a Magic Bullet works well), try these five easy shake upgrades to boost calories while keeping the shake balanced and nutritious.
