In this article, we’re diving into 11 of the best high-calorie foods to help you gain weight the healthy way. These aren’t just filler foods—they’ll help build lean muscle, improve your energy levels, and support your overall health. Let’s get into it!
Introduction
Trying to gain weight can feel like pushing a boulder uphill—especially when your metabolism seems to burn through calories like a furnace. While many people focus on shedding pounds, there’s a whole other side to the health and fitness spectrum that struggles with adding weight in a healthy way. Whether you’re recovering from an illness, trying to build muscle, or just naturally have a lean frame, gaining weight the right way is crucial.
But here’s the deal: not all calories are created equal. Loading up on sugary snacks, deep-fried fast food, and soda might increase your weight—but it won’t do your health any favors. The key lies in choosing high-calorie foods that are nutrient-dense, meaning they pack a serious punch of essential vitamins, minerals, protein, and healthy fats along with the calories.
1. Nut Butters (Peanut, Almond, Cashew)
Why Nut Butters Are Calorie Powerhouses
One tablespoon of peanut butter contains nearly 100 calories, and it’s mostly from healthy fats and a bit of protein. Nut butters are a classic go-to for anyone trying to gain weight because they’re compact, rich, and incredibly versatile. Whether you go for peanut, almond, cashew, or even sunflower seed butter, you’re getting a creamy boost of monounsaturated fats, fiber, and plant-based protein.
How to Include Them in Your Diet
The best part? Nut butters are super easy to add to your meals. Slather them on whole grain toast, blend them into smoothies, mix them into oatmeal, or just enjoy a spoonful as a quick snack. You can even add nut butter to yogurt or use it as a dip for apple slices and celery sticks for a balance of carbs, fat, and fiber.
Want a pro tip? Make a weight-gain shake with whole milk, bananas, a scoop of nut butter, honey, and a handful of oats. That’s a calorie bomb in the best way possible!
Nutritional Breakdown and Benefits
Here’s a quick look at the nutrient profile of 2 tablespoons of peanut butter:
- Calories: ~190-210
- Fat: 16g (mostly healthy fats)
- Protein: 7g
- Fiber: 2g
Beyond the calorie count, nut butters provide:
- Vitamin E for skin and immunity
- Magnesium for muscle and nerve function
- Niacin and B6 for energy metabolism
Make sure to go for natural versions without added sugars or hydrogenated oils for the healthiest option.
2. Whole Milk and Full-Fat Dairy
Rich in Calories and Nutrients
If you’ve been sticking with skim milk thinking it’s better, it’s time to switch lanes. Whole milk and full-fat dairy are incredibly efficient when you’re looking to gain weight. A single cup of whole milk has around 150 calories, along with a hearty dose of fat, protein, and carbs. And let’s not forget the calcium and vitamin D content that’s crucial for bone health.
Full-fat versions of yogurt, cheese, and cream offer even more calories in smaller portions, making them ideal for high-calorie snacking.
Best Ways to Consume Full-Fat Dairy
There are so many delicious ways to enjoy full-fat dairy. Pour it into your morning coffee or smoothies, top your cereal with it, or enjoy a glass with dinner. Full-fat Greek yogurt is a powerhouse—rich, creamy, and loaded with probiotics and protein.
Try these:
- Full-fat yogurt with granola and honey
- Mac and cheese made with whole milk and cheddar
- Whole milk lattes with a splash of flavored syrup
- Cottage cheese with fruit or honey
Comparisons Between Skim and Whole Milk
| Milk Type | Calories (per cup) | Fat | Protein | Calcium |
|---|---|---|---|---|
| Skim Milk | 80 | 0g | 8g | 30% DV |
| Whole Milk | 150 | 8g | 8g | 30% DV |
As you can see, the calorie and fat differences are significant—without sacrificing protein or calcium.
3. Rice and Other Whole Grains
High in Carbs, Easy to Digest
When it comes to calorie-dense carbs, rice is king. It’s cheap, easy to prepare, and can easily be paired with just about anything. A single cup of cooked white rice has over 200 calories and practically no fat. It’s a clean source of energy that can be eaten in large amounts without making you feel overly full.
If you’re someone with a fast metabolism or a busy lifestyle, rice can help you reach your calorie goals quickly.
Pairing Rice with Protein and Fats
To make your meals more calorie-dense and balanced, pair rice with high-protein and fat sources:
- Rice with butter and chicken curry
- Stir-fried rice with eggs and sesame oil
- Rice bowls with avocado, beans, and shredded beef
- Burrito bowls with cheese and sour cream
You can also add a dollop of ghee or coconut oil on top for an extra 100+ calories with a boost of flavor.
Best Whole Grains for Weight Gain
Besides white rice, consider:
- Quinoa – high in protein and calories
- Brown rice – more fiber, slightly lower in calories
- Oats – perfect for hearty breakfasts and shakes
- Barley and bulgur – great for soups and sides
Whole grains also deliver B-vitamins and iron, which are essential for energy metabolism and red blood cell production.
4. Red Meats (Beef, Lamb, Pork)
Protein and Fat-Rich Cuts
Red meat is a heavyweight when it comes to both calories and muscle-building potential. Fatty cuts of beef, lamb, and pork deliver not just protein, but also a good dose of saturated fat—key for testosterone production and weight gain. A 6-ounce ribeye steak? You’re looking at nearly 400-500 calories, depending on the cut.
Plus, red meat is rich in creatine, a naturally occurring compound that boosts energy and muscle performance.
Cooking Methods That Retain Calories
To maximize calorie content, avoid draining fats or grilling away juices. Instead:
-
- Pan-fry with butter or olive oil
-
- Roast with potatoes and olive oil
-
- Add cream-based sauces and gravies
-
- Stir-fry with vegetables in sesame or peanut oil
Ground beef is also great for making burgers, meatballs, tacos, and pasta sauces.
Muscle-Building Benefits
Red meat is high in:
-
- Complete protein (all 9 essential amino acids)
-
- Iron – critical for oxygen transport
-
- Zinc – supports immune health and hormone function
-
- Vitamin B12 – vital for energy and nerve health
It’s a great food for athletes and bodybuilders aiming to bulk up quickly and efficiently.
5. Nuts and Seeds (Almonds, Chia, Flax, Walnuts)
Nutrient-Dense and Convenient
Just a handful of mixed nuts or seeds can give you 200+ calories—and they’re ridiculously easy to snack on throughout the day. Almonds, walnuts, pistachios, chia seeds, and flaxseeds are full of healthy fats, protein, and fiber.
They’re also shelf-stable, meaning you can toss a bag in your car, your desk drawer, or your gym bag for an easy high-calorie bite whenever hunger strikes.
Creative Ways to Add Them to Meals
Try these simple ideas:
-
- Sprinkle seeds on yogurt, oatmeal, or salads
-
- Add crushed nuts to baked goods or smoothie bowls
-
- Stir nut flour into pancake or muffin batter
-
- Blend chia seeds into shakes for added texture and calories
Nut-based trail mixes with dried fruit and dark chocolate chips can be a super-charged weight gain snack.
Omega-3s and Healthy Fats
Many nuts and seeds are rich in omega-3 fatty acids, which support heart and brain health. Walnuts and flaxseeds, in particular, are top sources. You’ll also get:
-
- Vitamin E for skin and immune health
-
- Magnesium for muscle recovery
-
- Fiber for digestive balance
6. Avocados
Creamy, High-Calorie Superfood
Avocados are like the golden ticket of healthy weight gain. One medium avocado has around 250 to 300 calories, most of which come from heart-healthy monounsaturated fats. They’re also packed with fiber, potassium, folate, and vitamins C, E, and K. Unlike most fruits, avocados are low in sugar but high in calories, making them a perfect option for gaining weight without resorting to processed junk.
Their naturally creamy texture also makes them a great base or addition to meals. You get a rich, satisfying food that supports not only weight gain but also cardiovascular and skin health.
Great in Both Sweet and Savory Dishes
Avocados are versatile. You can enjoy them mashed on toast, diced in salads, blended into smoothies, or turned into guacamole. You can even use them as a butter substitute in baking! Here are some creative, calorie-dense ways to enjoy avocados:
-
Avocado and egg toast with olive oil drizzle
-
Smoothies with avocado, banana, Greek yogurt, and honey
-
Avocado chocolate mousse made with cocoa powder and maple syrup
-
Stuffed avocados with tuna, chicken salad, or hummus
Want to boost the calorie count? Just add olive oil, nuts, or seeds into the mix.
Vitamins and Heart-Healthy Fats
Here’s what you get in one medium avocado:
-
Calories: ~250
-
Fat: 23g (15g monounsaturated)
-
Fiber: 10g
-
Potassium: More than a banana
Thanks to their nutrient profile, avocados help maintain healthy cholesterol levels and improve nutrient absorption from other foods, especially fat-soluble vitamins like A, D, E, and K.
7. Dark Chocolate
Rich in Calories and Antioxidants
If you’ve got a sweet tooth, dark chocolate is one of the tastiest and healthiest high-calorie options out there. A 100-gram bar of high-quality dark chocolate can pack around 500–600 calories, depending on the cocoa content. It’s loaded with antioxidants like flavonoids and polyphenols, which support heart health and fight inflammation.
Dark chocolate also provides small amounts of caffeine, which can improve mood and alertness—so yes, it’s basically happiness in a square.
How to Eat It Smartly
Choose 70% cocoa or higher for maximum health benefits. Lower cocoa percentages often come with added sugar and fewer antioxidants. Here’s how to incorporate dark chocolate into your day:
-
Add chopped dark chocolate to oatmeal or yogurt
-
Pair it with nuts for a calorie-packed snack
-
Use cocoa nibs in smoothies or baked goods
-
Melt dark chocolate and drizzle over fruits or pancakes
Bonus: Try dark chocolate with peanut butter on toast. Trust us, it’s a game-changer.
Choose the Right Cocoa Percentage
| Cocoa Content | Benefits | Calories (per 1 oz) |
|---|---|---|
| 50–60% | Mild taste, more sugar | 130–150 |
| 70–85% | High antioxidants, less sugar | 150–170 |
| 85–99% | Intense taste, very low sugar | 160–180 |
Besides calories, dark chocolate gives you iron, magnesium, copper, and manganese. Just don’t go overboard—stick to a few squares per day for the best balance of indulgence and nutrition.
8. Dried Fruits (Raisins, Dates, Apricots)
Concentrated Calories and Sugar
Dried fruits are basically fresh fruits with the water removed—so they’re more calorie-dense and way easier to overeat. That’s a good thing if you’re trying to gain weight. A small handful of raisins (about ¼ cup) provides over 120 calories, while dates and apricots offer even more.
Because they’re naturally sweet, dried fruits also make great pre-workout snacks or dessert toppings. Just be sure to choose unsweetened versions to avoid added sugars.
Use Them as Snacks or Toppings
Here are some delicious ways to use dried fruits to your advantage:
-
Add dates to smoothies or shakes for a sweet, thick texture
-
Mix dried apricots or raisins into trail mixes with nuts and seeds
-
Sprinkle chopped figs or cranberries on salads or yogurt
-
Blend dates and almonds to make high-calorie energy bites
You can also soak dried fruits in water or milk overnight for a softer texture and improved digestion.
Natural Energy Boost
Dried fruits are rich in:
-
Natural sugars (glucose and fructose) for quick energy
-
Fiber for digestive health
-
Iron, especially in raisins and apricots
-
Antioxidants, particularly in prunes, goji berries, and cranberries
They’re ideal for people on-the-go who need compact, nutritious calorie sources throughout the day.
9. Whole Eggs
Balanced Protein, Fat, and Nutrients
Eggs are among the most nutrient-dense and cost-effective high-calorie foods you can eat. One large egg has about 70–80 calories, but if you eat them scrambled in butter or made into an omelet, that number can climb quickly. Plus, you’re getting a balance of high-quality protein (all essential amino acids), fat, and crucial micronutrients like B12, selenium, and choline.
Contrary to outdated myths, eating whole eggs—including the yolk—is perfectly healthy for most people.
Cooking Techniques That Preserve Nutrition
The beauty of eggs is in their flexibility. Here are some calorie-maximizing methods:
-
Omelets with cheese, avocado, and veggies
-
Scrambled eggs in butter or ghee
-
Hard-boiled as a protein-rich snack
-
Egg salad with mayonnaise on whole wheat bread
Eggs also work great in high-calorie breakfasts. Think French toast, frittatas, and egg muffins with sausage or bacon.
Debunking Cholesterol Myths
Yes, eggs contain cholesterol—but that doesn’t mean they raise cholesterol in your blood. In fact, many studies have shown that eggs can:
-
Increase good HDL cholesterol
-
Improve eye health (thanks to lutein and zeaxanthin)
-
Support brain health (thanks to choline)
The key is moderation and balance. Eating 2–3 eggs per day as part of a nutrient-rich diet is completely safe for most people—and ideal for weight gain goals.
10. Potatoes and Starches
Starchy Calories That Fill You Up
Potatoes often get a bad rap, but they’re one of the best foods for healthy weight gain when cooked right. A medium potato provides about 160–200 calories, and they’re rich in carbs, fiber (especially with the skin), potassium, and vitamin C.
Other starchy vegetables like sweet potatoes, corn, and peas also deliver a strong calorie punch. Plus, starches help replenish glycogen stores, making them excellent post-workout foods.
Best Starches for Bulk Meals
Here’s a list of some top calorie-rich starches:
-
White potatoes – baked, mashed, or roasted
-
Sweet potatoes – with butter, cinnamon, or honey
-
Corn – fresh, grilled, or in chowder
-
Peas and lentils – in soups, stews, and curries
-
Butternut squash – roasted or pureed
Don’t forget whole grain pasta, brown rice, and couscous for high-carb, high-calorie meal foundations.
Cooking Tips to Maximize Calorie Intake
To boost your intake even more:
-
Add butter, cheese, or sour cream to mashed potatoes
-
Drizzle olive oil on roasted sweet potatoes
-
Cook fries or wedges in healthy oils like avocado or coconut
-
Mix starchy veggies into calorie-rich stews or casseroles
Carb-rich foods like these are great for people with high metabolisms or athletes looking to build serious muscle mass.
11. Healthy Oils (Olive Oil, Coconut Oil, Ghee)
Add to Meals for Extra Calories
If you’re looking for a super simple way to add hundreds of calories to your meals without increasing the volume, healthy oils are the answer. Just one tablespoon of olive oil contains about 120 calories, all coming from fat—mostly the heart-healthy monounsaturated kind.
Oils like olive oil, coconut oil, avocado oil, and ghee are calorie-dense and also rich in beneficial compounds that support your heart, brain, skin, and hormones.
Unlike carbs or protein, fats are more energy-dense—offering 9 calories per gram versus 4 from carbs or protein. This makes oils an efficient way to boost your intake, especially if you have a small appetite or want to avoid constantly eating large meals.
Cooking and Dressing Ideas
Healthy oils are incredibly versatile. Here are some ways to work them into your diet:
-
Drizzle olive oil over salads, pasta, and grain bowls
-
Use ghee or coconut oil for sautéing vegetables and frying eggs
-
Blend MCT or coconut oil into smoothies and coffee
-
Add oil to soups, stews, or hummus for extra richness
You can also use nut oils (like walnut or macadamia oil) in vinaigrettes or drizzle them on top of roasted veggies for both flavor and a calorie boost.
Fats That Support Hormonal Health
Fats are crucial for hormone production, especially testosterone, estrogen, and cortisol. Diets too low in fat can lead to hormonal imbalances, fatigue, and mood swings. The healthy fats found in oils also:
-
Support brain function
-
Help the body absorb fat-soluble vitamins (A, D, E, K)
-
Improve skin and hair health
-
Reduce inflammation
Aim to include at least 2–3 tablespoons of healthy oil in your daily meals when trying to gain weight.

FAQs
1. How quickly can I gain weight by eating high-calorie foods?
Weight gain depends on your current metabolism, activity level, and how many calories you’re consuming above your maintenance level. A healthy rate is around 0.5 to 1 pound per week. To gain one pound, you need a surplus of about 3,500 calories, so adding 500 extra calories a day is a good starting point.
2. Can I gain weight without eating unhealthy junk food?
Absolutely. Junk food may increase your weight, but it often adds more fat than muscle and can negatively impact your health. Instead, focus on nutrient-rich foods like those mentioned in this article to gain lean mass and stay energized.
3. What are the best times to eat for weight gain?
There’s no “best” time, but spreading your calorie intake across the day is helpful. Try:
-
High-calorie breakfasts
-
Snacks between meals
-
Pre- and post-workout meals
-
A calorie-dense meal or snack before bed
Eating every 3–4 hours can keep your metabolism running and prevent you from feeling too full at any one meal.
4. Should I exercise while trying to gain weight?
Yes! Strength training is especially important. It helps convert the extra calories you’re consuming into lean muscle rather than just body fat. Aim to lift weights 3–5 times a week while focusing on progressive overload and compound movements.
5. How do I avoid gaining only fat?
To minimize fat gain:
-
Focus on whole, high-calorie foods with balanced macros
-
Incorporate resistance training
-
Avoid large calorie spikes from sugary, empty foods
-
Get enough sleep and manage stress
This approach helps ensure most of your weight gain is muscle-based.
