Smoothies for weight gain.

Enjoying a daily, high-calorie smoothie is a great way to help you gain weight. They're quick to make, easy to take with you on the go, and can be made with an infinite combination of ingredients and flavors. Not to mention, they taste absolutely delicious too!

In these smoothies for weight gain, you'll notice many of them contain similar ingredients. If you stock your kitchen pantry with these 8 staple ingredients, you can have a new smoothie every day and help yourself keep on weight or gain weight!

1. Nuts

Nuts and nut butters with spoon dipped in almond butter.

Nuts are chalked full of those healthy fats and can be added to smoothies in a number of ways. They're also a great source of fiber, vitamins and minerals and depending on the nuts you use, can be mild in flavor or extra nutty.

If you have a high powered blender, you can add a small handful of nuts (start with a tablespoon or two) directly into your smoothie and blend until smooth. If you have a low-powered blender or want an extra creamy flavor, try adding your favorite nut butters.

Almonds, almond butter, cashews, cashew butter, peanuts, peanut butter, walnuts and pecans are a great start.

2. Avocado

Similar to nuts, adding ripe avocado to your smoothie is a great way to boost your smoothie's calories and get a good source of healthy fats. Avocados are also great to use if you have a low-powered blender because they are so soft and creamy.

They're also a great addition to high-calorie smoothies because the flavor of the avocado is easily masked by nut butters, cocoa powder, or frozen fruit.

Adding ½ an avocado to any smoothie immediately adds 130 calories!

3. Coconut

Coconut milk, MCT oil, and coconut shreds.

If you are looking to add calories to your smoothies, replacing the water or nut milks with coconut milk is an easy switch. Nut milks like almond milk or oat milk, especially when purchased commercially are heavily watered down and relative low in calories. Coconut milk is made from coconut meat and is high in plant-based saturated fat.

Replace some or all of the liquid in your smoothie with full-fat coconut milk for a rich, creamy, high-calorie smoothie. Just ½ a cup of canned coconut milk contains about 220 calories.

If you don't have coconut milk, try adding a tablespoon of MCT oil or a ¼ cup of shredded coconut.

To start, try one of these high-calorie smoothie recipe ideas featuring coconut milk. You will be blown away by the creamy, luscious texture it provides.

4. Seeds

Adding seeds to your smoothies is very similar to using nuts. This is a popular, easy alternative if you are allergic to nuts. Seeds are also typically easier to blend smooth in a smoothie than nuts like almonds or pecans.

Some of our favorite seeds to use when making high-calorie smoothies are chia seeds, hemp seeds, and flaxseeds. They are very mild in flavor and an amazing source of Omegas and healthy fats.

You can also make high-calorie smoothies with tahini and seed butters like sun butter for a creamy nut butter like taste.

5. Dates

When thinking of making high-calorie smoothies, you may not think to include fruits like dates, but these small tropical fruits are high in calories, fiber, and nutrition. Just a 1/4 cup of chopped dates can contain 100+ calories!

If you have a low-powered blender, we recommend soaking the dates in hot water for 5-10 minutes before adding them to your smoothie to help soften them up. Dates can be pretty tough and sticky and this will help your blender process them until smooth.

And don't forget! Make sure to pit your dates before adding them to the smoothie. If you accidentally leave the pits in, it can damage your blender blades.

Give dates a try in one of these three high-calorie smoothies:

6. Bananas

Three bunches of bananas.

Like dates, you may not associate bananas with higher calories. But bananas are high in carbs and contain about 100 calories per banana. They are much more calorically dense than fruits like watermelon, strawberries, raspberries, or kiwi.

Frozen bananas also make a very creamy, ice cream like texture that is optimal for creamy smoothies and smoothie bowls.

Try adding frozen bananas to one of these favorite high-calorie smoothies for weight gain:

7. Protein Powder

Fruity protein smoothie.

Adding a scoop of protein powder is possibly the easiest way to get a wide array of vitamins, minerals, protein and calories to any smoothie. Depending on the protein powder you use, you can add anywhere from 100 to several hundred calories to your smoothie per serving.

I love the Tone It Up protein powder because it's mild in flavor and works well in baking too.

Use these smoothies as inspiration for a high-protein and high-calorie smoothie!

8. Oats

A wooden bowl and spoon with rolled oats.

Adding oats to a smoothie is one of our favorite tricks for making a smoothie thicker and richer in calories. It's also one of the best ways to add calories to a smoothie while keeping it relatively low in fat. If you've never tried adding oats to your smoothie before, think of it as a smooth, drinkable oatmeal!

All you need is 1/4 cup of rolled oats and you'll boost your smoothie by 150 calories.
