10 High-Calorie Snacks for Healthy Weight Gain
Fuel your body with nutrient-rich bites that boost energy and deliver protein and fats.
Gaining weight can be as challenging as losing it, especially if you have a fast metabolism, a demanding lifestyle, or specific medical needs. Consuming more calories than your body burns is essential for weight gain — but not all calories are equal. Dietitians emphasize the importance of choosing nutrient-dense, high-calorie snacks that provide vital vitamins, minerals, protein, and healthy fats. This guide shares effective, delicious snack ideas to help you reach your weight goals without sacrificing health.
Why Choose High-Calorie Snacks?
For many, eating large meals is difficult due to time constraints, small appetites, or full schedules. High-calorie snacks bridge this gap by packing energy and nutrients into small, manageable portions. Such snacks are crucial for:
- Building lean muscle for athletes or active individuals
- Recovering from illness, surgery, or periods of insufficient nutrition
- Supporting growth in children, teens, and pregnant women in need of extra calories
When chosen wisely, snacks can supply the necessary energy while improving diet quality with protein, healthy fats, and fiber.
1. Full-Fat Greek Yogurt
Greek yogurt, especially the full-fat variety, stands out as a protein- and calorie-packed snack. It contains probiotics for gut health and is rich in calcium and vitamin B12. Compared to lower-fat yogurts, full-fat options offer much more energy: a typical serving provides about 220 calories and 11 grams of fat per cup, in contrast to less than 100 calories in nonfat versions. However, it does contain some saturated fat, so portion management is important, as most adults should limit saturated fat intake to about 13 grams per day for heart health.
What makes Greek yogurt versatile is how you can enjoy it:
- Layer it with oats, nut butter, nuts, coconut flakes, and chia seeds to create overnight oats.
- Top with fresh or dried fruits such as berries, sliced bananas, or mango for natural sweetness.
- Blend into smoothies for an extra creamy texture and a protein boost.
2. Trail Mix
Trail mix is a customizable, convenient snack comprised mainly of dried fruit, nuts, and sometimes extras like coconut flakes, banana chips, or dark chocolate. Dried fruit is calorie-dense because it contains much less water than fresh fruit; a handful of macadamia nuts or pecans (about an ounce) provides nearly 200 calories. Combining nutrient-packed ingredients delivers healthy fats, protein, antioxidants, and plenty of calories in a small serving.
Some creative trail mix combinations include:
- Almonds, dried cranberries, dark chocolate pieces, and toasted coconut chips.
- Pecans, banana chips, and unsweetened dried mango for a tropical flair.
- Add to yogurt or oatmeal for crunch and extra energy.

3. Nut Butters
Nut butters — think peanut, almond, or cashew — offer concentrated calories, healthy unsaturated fats, and plant-based protein. Just two tablespoons typically provide around 180-200 calories, depending on the type. Choose options with minimal added sugar and no hydrogenated oils for maximum health benefit.
Easy ways to add nut butter to your diet:
- Spread on toast, rice cakes, or whole-grain crackers.
- Swirl into oatmeal or overnight oats.
- Dip fresh apple slices or celery stalks for a satisfying bite.
- Add a scoop to smoothies for extra creaminess and nutrition.
4. Avocado Toast
Avocados are loaded with heart-healthy monounsaturated fats, fiber, and a range of vitamins and minerals. Half an avocado accounts for about 120 calories and pairs exceptionally well with whole grain bread for a filling snack. Avocado toast can be customized endlessly:
- Smashed avocado with a sprinkle of sea salt, crushed red pepper, and olive oil.
- Add a poached egg, sliced tomato, microgreens, or smoked salmon for extra nutrients and calories.
- Top with crumbled feta, pumpkin seeds, or hemp hearts for a savory upgrade.
5. Granola
Granola mixes rolled oats, dried fruit, nuts, seeds, and sweeteners like honey or maple syrup. Half a cup can contain up to 300 calories or more, depending on the mix. Choose granolas that are made with whole grains, minimal added sugars, and real ingredients to avoid empty calories and excess saturated fat.
Enjoy granola by:
- Eating a handful as a crunchy snack on the go.
- Mixing with milk or plant-based alternatives for cereal.
- Layering on top of Greek yogurt, smoothie bowls, or as a salad topper for added texture.
6. Eggs
Eggs are a nutrient powerhouse, providing protein, healthy fats, vitamins (including the hard-to-find vitamin D), and minerals like choline, which is important for brain development and liver health. A large egg contains about 70 calories, and eggs are easy to combine with other calorically dense foods: mashed avocado on toast, cheese in an omelet, or in an egg salad sandwich.
Snack ideas with eggs:
- Deviled eggs made with Greek yogurt, mayo, or hummus.
- Egg salad sandwiches with whole grain bread and creamy add-ins.
- Hard-boiled eggs as a portable protein boost.
7. Cheese
Cheese, made from full-fat milk, is dense in calories and protein. Different varieties offer different calorie counts, but on average, one ounce of cheese delivers 100-120 calories and 6-7 grams of protein.
Ways to enjoy cheese as a snack include:
- Pair slices of cheddar, Swiss, or gouda with whole grain crackers.
- Toss cubes of cheese with dried fruit and nuts for a savory-sweet combo.
- Spread soft cheeses like ricotta or cream cheese on toasted bagels, rice cakes, or fruit.
8. Dried Fruits
Dried fruits — raisins, dates, apricots, figs, cherries — condense the calories and nutrients found in fruit into a smaller, easily consumable portion. For example, a quarter cup of raisins has about 110 calories. Dried fruit is naturally rich in fiber, vitamins, and antioxidants, making it a valuable snack for weight gain.
Snack ideas with dried fruits:
- Eat alone or as part of a homemade trail mix.
- Stuff dates with nut butter or cream cheese for a decadent bite.
- Add to cereal, salads, baked goods, or yogurt parfaits.
9. Smoothies and Shakes
Homemade smoothies and shakes can be loaded with nutrient-dense choices for maximum calories. Blending together full-fat yogurt, nut butters, milk or plant-based alternatives, oats, frozen fruit, and seeds lets you customize both taste and calorie content. Such shakes are especially effective for those who struggle with solid foods or who want a convenient, quick snack.
Ideas for calorie-packed smoothies:
- Banana, peanut butter, oats, and Greek yogurt smoothie
- Avocado, cocoa powder, almond milk, and honey shake
- Mango, coconut milk, chia seeds, and protein powder blend
10. Whole Grain Breads and Bagels with Nut Butter or Cheese
Whole grain breads and bagels are excellent sources of healthy carbs and fiber. They also provide a sturdy base for a range of high-calorie toppings. A typical large bagel may contain 250–300 calories before you add any spreads.
Easy snack preparations include:
- Bagel with a thick layer of peanut or almond butter, topped with banana slices or honey.
- Whole grain toast with mashed avocado, smoked salmon, or cottage cheese.
- Melted cheese on seeded whole grain bread for a gooey, warming treat.
Additional Tips for Gaining Weight Healthfully
- Eat frequently: Aim for three main meals and two or three snacks per day.
- Choose nutrient-dense foods: Focus on foods rich in vitamins, minerals, and healthy macronutrients.
- Watch for added sugars and unhealthy fats: Select snacks with real food ingredients, and limit trans fats and excessive added sugars.
- Stay active: Regular exercise, especially strength training, supports muscle rather than fat gain.
- Consult with a registered dietitian: Especially important if you have a medical condition or unique dietary requirements.
