These high-calorie snacks will help you gain weight in a healthy way (2023)

There are a variety of reasons why one may need to gain weight, including genetics and certain medical conditions such as fat malabsorption, cancer treatment, pregnancy, and to improve athletic performance. While foods high in saturated fat may be the first things that come to mind, there are plenty of healthy options, packed with protein and healthy fats, that can help you gain weight. Snacking between meals can be a good start.

"As you increase your caloric intake, try to focus on nutrient-dense, high-calorie choices. You can still prioritize healthy foods while gaining weight rather than resorting to options laden with added sugar and excess sodium.says a registered dietitianStephanie Sassos, Director ofInstitute for Good Housekeepingnutrition laboratory. She adds, "Fat has more calories per gram than protein or carbs, which means you don't have to quantitatively eat as much to get the same amount of calories. Nutritious fats to add to your diet to support healthy weight gain include olive oil, full-fat yogurt and milk, avocado, nut butters, and oily fish."

Many athletes need to consume an increased number of calories per day to maintain and/or gain weight and muscle mass due to the high amount of calories burned during their sport and training. Our team of registered dietitians in theGood Housekeeping Nutrition LabI consulted with college and pro athletes about some of their favorite snack foods for this story.

Nuts and seeds are crammed full of healthy thingsmonounsaturated fats alongside omega-3 fatty acids, fiber, protein, antioxidants, vitamins and minerals. Research suggests that increased consumption of nuts and seeds is associated with areduced risk of cardiovascular disease. While most nuts and seeds are high in calories,MacadamianüsseAndPecannüssecontain the highest calorie count at about 200 calories per ounce. (Compare that to 164 calories per ounce in almonds.)

A handful of nuts is the easiest snack of them all, or mix and match your favorite nuts and seeds with dried fruit to create a DIY student mix. Nut or seed butters (almond butter, cashew butter, sunflower butter, etc.) are great on toast or a bagel, with an apple, stuffed in dates, or added to full-fat Greek yogurt.

Warning: some brands are high in added sugar and sodium. We recommend looking for unsalted or lightly salted nuts and seeds, and when shopping for nut and seed butters, look for brands that don't contain sugar, sodium, hydrogenated oils, or unnecessary additives.

Full fat Greek yogurt

Full-fat Greek-style yogurt is packed with protein, probiotics and calcium, and also contains vitamin B12. Compared to low-fat or skim milk yogurt, full-fat Greek yogurt ismuch more calories (220 calories vs. 90 calories) and fat (11 grams vs. 0 grams), which helps make it a nutrient-dense treat.It contains some saturated fat, so keep an eye on that number. We recommend limiting saturated fat to about 3 grams per meal. Consuming more than the recommended daily limit of saturated fat (about 13 gramson a 2,000 calorie diet) can increaseLDL cholesterol, which increases your risk of heart disease and stroke.

Greek yogurt is super versatile and can be enjoyed in sweet or savory high-calorie snacks. Keep in mind that flavored and fruit-infused options can have a lot of added sugar, so look for brands that keep it to a minimum. For a delicious, nutrient-dense snack idea, try mixing full-fat Greek yogurt with rolled oats, nut butters, nuts, coconut flakes, and chia seeds to make overnight oats. Top it up with fresh or dried fruit when you're ready to eat.

Dried fruit contains more highly concentrated calories in a smaller volume than fresh fruit.Combine dried fruit with mixed nuts — remember that macadamia and pecans are the most calorie-dense at around 200 calories per ounce — and throw in some dark chocolate chunks, coconut flakes, and banana chips and you've created a high-calorie snack. Eat between meals to increase your total calorie intake, or use as a topping for full-fat Greek yogurt or add to oatmeal.

These powders are also high in protein and carbohydrates and are considered a popular way to increase calorie intake, especially among athletes.

Protein powders are classified as dietary supplements and subject to FDA oversight, although the industry as a whole is poorly regulated.We recommend looking for brands that do third-party testing through credible institutionssuch asUSP,NSF,consumer lab,laboratory,Informed choice and informed sportensure quality standards.

For a nutrient-dense smoothie idea, combine full-fat chocolate milk with a banana, 2 tablespoons peanut butter (or nut butter of your choice), and protein powder to create a high-protein, high-calorie snack. You can also add some avocado or full-fat Greek yogurt for extra calories.

Oats are a favorite among the athletes we consulted because they can be a palatable vehicle for other high-calorie foods like nuts and nut butters, granola, dried fruit, dark chocolate, and full-fat yogurt. We recommend sticking with unrefined and whole oats, including rolled, steel cut, and grits, as these are also more effectivelowering cholesterol levels.

Many athletes we spoke to reported that they start the day with eggs for breakfast to get a good amount of protein and healthy fats, and you can eat lots of them without feeling full.

Some egg snack ideas include egg salad sandwiches anddeviled eggsboth of which can be made with mayonnaise, full-fat Greek yogurt, or hummus to create a high-calorie, hearty treat.

Strategies for healthy weight gain

When it comes to weight gain, the simple fact is that you need to add more calories every day. This should be done in a thoughtful manner to gain weight slowly and steadily. Be strategic and follow these four suggestions:

✔️Add to smoothies and shakes:Drinking beverages with meals can make you feel full, so consume high-calorie drinks like smoothies or meal-replacement shakes between meals to avoid overfilling.

    ✔️Eat more often:Instead of eating two to three meals a day, try smaller, more frequent meals every few hours. Smaller meals can be easier to digest, making you feel less full and allowing you to eat again sooner.

    ✔️Add healthy fats:Add dips, sauces, and nut butters to your snacks to boost your calories. Drizzle olive oil over savory snacks like hummus, full-fat Greek yogurt dips, baked potatoes, soups, fish and eggs. Add nut butters to smoothies, Greek yogurt, and oatmeal, and add them to waffles and pancakes as a topping.

    ✔️Avoid low-fat products:Avoid products advertised as diet, light, low-fat, or lower in calories. Instead, look for products made with full-fat, whole milk, olive oil, and other nutrient-dense ingredients.

    The bottom line

    Weight gain can be achieved through a healthy and nutritious diet. We recommend being strategic with your eating plan and eating high-calorie foods frequently, but spread out throughout the day.

    Just remember to stay away from highly processed foods high in sugar and sodium. With any new diet or change to your health plan, we recommend working with a registered dietitian or healthcare provider to first determine if weight gain is indicated for you and how much weight gain is healthy for you and your individual needs. We also recommend working with your healthcare provider to develop a plan that is sustainable for you and will allow you to gain weight within a healthy time frame.
