Avocado, quinoa, and tahini are just some examples of high-calorie vegan foods that may support healthy weight gain.

Gaining weight can be incredibly difficult and often involves modifications to both your diet and lifestyle.

Eliminating animal products from your diet makes it even more challenging to put on weight and can require you to make strategic food choices.

That said, there are plenty of nutritious vegan foods that can add the extra calories to your diet needed for weight gain.

Here are 11 high-calorie vegan foods that can help you gain weight.

Nuts are a great source of protein, healthy fats and calories, making them an excellent choice if you’re looking to gain weight.

For example, walnuts pack 185 calories and over 4 grams of protein in a single 1-ounce (28-gram) serving (1).

A daily handful or two of nuts like almonds, cashews, walnuts or pecans can add enough calories to your diet to support healthy weight gain.

Nut butters, which are high in calories, are a quick and convenient option as well — though you should opt for natural varieties free from added sugar or oils. Add nut butter to snacks, sides or smoothies for a boost of protein and calories.


Nuts and nut butters are especially high in calories and protein. They can be enjoyed in a number of ways.

Avocados are renowned for their creamy texture and delicious, mild flavor.

They also boast an impressive nutrient profile and help promote healthy weight gain by supplying plenty of heart-healthy fats and fiber.

Just one avocado boasts about 322 calories, 13.5 grams of fiber and almost 30 grams of total fat (2).

Avocados are also rich in a range of micronutrients, including vitamin C, folate, pantothenic acid and potassium (2).

It’s also high in calories, as 1 cup (185 grams) of cooked quinoa holds about 222 calories, 8 grams of protein and 5 grams of fiber (3).

Quinoa is one of the few complete plant-based sources of protein, meaning that it provides all nine essential amino acids. Your body is unable to produce these on its own and must obtain them from food (4).

Quinoa also supplies a good amount of manganese, magnesium, phosphorus, copper and folate (3).

It functions as a satisfying side dish and can be added to soups, stews and salads for an easy way to squeeze in more calories.

Rich in healthy monounsaturated fats, olive oil is well known for its health-promoting properties.

Monounsaturated fats have been shown to increase levels of “good” HDL cholesterol, reduce blood triglycerides and help improve blood sugar levels in people with type 2 diabetes (6).

Olive oil is also high in antioxidants, which are beneficial compounds that prevent oxidative damage to your cells and reduce your risk of chronic disease (7, 8).

Plus, with 119 calories and 13.5 grams of fat in a single tablespoon (14 grams), olive oil can also be a healthy way to add extra calories to a meal.

Drizzle it over cooked veggies, mix it into a salad dressing or add it to marinades to bring a burst of flavor and calories to your meals.

Dried fruit is a great way to gain extra calories, vitamins, minerals and antioxidants.

Exact nutritional content can vary based on the type of fruit, ranging from prunes — which have 209 calories in a half cup (87 grams) — to raisins — which have 247 in a half cup (83 grams) (9, 10).

Studies note that dried fruit is rich in fiber and antioxidants and supplies micronutrients that are 3–5 times more concentrated than in fresh fruit (11, 12).

Because dried fruit is also high in natural sugars, it’s best to combine it with a nutritious protein source to minimize the potential effects on your blood sugar.

Mix your choice of dried fruit with coconut yogurt or oatmeal for a high-calorie breakfast, or try it with nuts and seeds as a tasty trail mix. You can also add it to protein shakes.
