High Calorie Fruit Smoothies for Weight Gain (RD-Created!)

Whether you’re trying to bulk up for aesthetic reasons or to regain the weight lost after an illness, high calorie fruit smoothies are an incredible tool for adding extra calories and protein to your diet. 

They’re also a great way to eat more fruit. Fruit smoothies are easily customizable, allowing you to mix and match your favorite nutrient-dense foods for endless flavor combinations.

That said, making smoothies from fruit alone won’t be very effective for weight gain since fruit is relatively low in calories. To bump up the calories, you’ll need to add some protein and fat. This will give your smoothies a slightly thicker consistency, like something between a smoothie and a shake, but they’ll still taste delicious.

To get you started, I’ve created three high calorie fruit smoothie recipes using a variety of protein sources and fruit flavors.

3 High Calorie Fruit Smoothies

1. Peanut Butter Banana Smoothie

This peanut butter banana smoothie is perfect for peanut butter lovers! Peanut is the primary flavor, so feel free to add more banana if you like.

How to make your own high calorie fruit smoothies

Don’t be afraid to create your own! You can easily customize your own fruit smoothies by following the guidelines below. Some of these will overlap, which is okay. You just want to make sure that all components are included in your smoothie. 

1. Choose your liquid

When trying to boost the calorie and protein content of your smoothie, I recommend choosing high-protein plant-based milks. These include:

  • Soy milk
  • Pea milk (such as Ripple brand)
  • Other non-dairy milks like almond or oat that have been fortified with additional protein

These types of dairy-free milk alternatives provide about 7-10 grams of protein per cup, compared with 0-2 grams in regular almond, rice, and oat milk.

You can also add fruit juice for a brighter, fresher flavor.

Since high-calorie smoothies tend to have a thick consistency, you may need to add water to help it blend and make it easier to drink through a straw. Avoid making it too thin, however, as you may not be able to finish the whole thing especially when dealing with a decreased appetite.

2. Choose your fruit

This is where you’ll want to think about the flavor profile that sounds best to you. Some of the best fruits for smoothies include:

  • Bananas: add creaminess and calories; mild taste that goes with variety of flavor profiles
  • Mixed berries
  • Strawberries
  • Stone fruits (cherries, peaches, apricots)
  • Mango
  • Pineapple

You’ll likely want to include some frozen fruit to make your smoothie cold enough. Since we’re going for high-calorie recipes, we don’t want to dilute the smoothie with too much ice or water.

3. Choose your protein source

Some of the best vegan protein sources make excellent smoothie add-ins. Choose from:

  • High-protein non-dairy milk
  • Plant protein powders
  • Hemp seeds
  • Chia seeds
  • Nut butter
  • Silken tofu

4. Choose your calorie add-in

Since fat is higher in calories than protein or carbs, you’ll likely need to include a source of fat in your smoothie to bump up the amount of calories it provides. A few examples of calorie-rich ingredients include:

  • Avocado
  • Nut butter
  • Hemp seeds
  • Chia seeds
  • Flaxseed oil
  • Avocado oil
  • Higher-fat vegan yogurt, like coconut yogurt
  • Canned coconut milk
  • Vegan ice cream

5. Choose flavor add-ins

If you aren’t quite happy with your smoothie as-is, try some of the following flavor-boosters:

  • Cinnamon
  • Cocoa powder
  • Maple syrup
  • Agave nectar
  • Jam
  • Instant coffee
  • Chocolate sauce
  • Dairy-free hazelnut spread
  • Fruit juice
