High Calorie Smoothies for Weight Gain

High calorie smoothies are a great way to add calories and get an extra boost of nutrition. When someone is experiencing unintended weight loss or just needs to gain a few pounds, calories are the answer.

Sometimes it’s hard to get additional calories from regular meals. Adding a high calorie smoothie is a great option to maximize intake. It can be easy to sip on a weight gain smoothie in between meals.

I am a big fan of both high calorie shakes and smoothies. High calorie smoothies are often packed more vitamins and minerals. The key is providing a high calorie beverage that someone will actually drink. Whether it’s a smoothie or a shake there are so many options.

How to Make a High Calorie Smoothie

It’s pretty simple to get started. You just need to add a bunch of ingredients into a good blender. Experiment with what works best. Add more liquid if it’s too thick. Add more solid ingredients if it’s too thin.

Here are some basic ingredients to add to your high calorie smoothies:

  1. Vegetables
  2. Fruits
  3. Liquid
  4. Dairy
  5. Nuts/ Seeds
  6. Add ins

Let’s review some examples of what you add to a smoothie. We’ll end with some sample recipes to get you going! Keep in mind these are just some ideas.


Vegetables for Smoothies

Most vegetables are actually quite low in calories. But they do provide a ton of vitamins and minerals. And they can add some fun taste and even color to a smoothie.

  • Avocados
  • Carrots
  • Spinach
  • Kale

Avocados reign as the highest calorie option here. They are high in heart healthy fats. And they will give a creamy taste to any smoothie. Carrots add a hint of sweetness. And greens often have a minimal taste, but add a nutrient boost.

Fruits for Smoothies

Fruits can be moderately high in calories but are also jam packed with vitamins and minerals.

  • Strawberries
  • Bananas
  • Pineapple
  • Apple
  • Orange
  • Berries

The banana is a great high calorie option. There are around 100 calories in a medium sized banana. It will give some creaminess to a smoothie and tastes good. Sky is really the limit for fruits to add to a smoothie. There are a ton of different options!

Liquids for Smoothies

All smoothie needs some liquids to get them blended up and ready to drink. We do not want to add water to high calorie smoothies. Water has no calories. We want to make sure every ingredient that goes into the blender is high in calories.

  • Whole milk
  • Half and half
  • Soy milk
  • Orange juice
  • Apple juice
  • Cranberry juice
  • Pineapple juice

Half and Half has the most calories of the options listed. It will make the smoothie very creamy and borderline on a milk shake. But any juice or milk option will do here! Some plant-based milks are lower in calories- try to pick the options with the most calories.

Dairy for Smoothies

Dairy products can be high in calories if we use the whole fat options. A couple of dairy items were listed in the liquids section above, but let’s cover some more dairy options you can add.

  • Yogurt
  • Greek Yogurt
  • Cottage Cheese
  • Ice-cream
  • Sherbet

Be sure to read the nutrition labels and get the options with the HIGHEST number of calories.  Often times dairy products are sold as “light” or lower in calories… a majority of the public isn’t looking to gain weight. Food marketers are often targeting weight loss in dairy products.

Nuts/ Seeds for Smoothies

Nuts and seeds are high in heart healthy fats. This is a great option if you have a good blender. If you don’t have the strongest blender and don’t want too much texture, use powdered nuts/seed or pre-made nut or seed butters.

Graphic showing nuts and seeds to add to smoothiesHere are some nuts/seeds to add to smoothies:

  • Peanut butter
  • Almond butter
  • Walnuts
  • Almonds
  • Flax seed
  • Chia seed

Flax and chia seed are high in omega-3 fats. Peanut butter is super high in calories and a tasty edition to a smoothie- depending on the ingredients.

Add ins for Weight Gain Smoothies

But wait, there’s more! Here are some high calorie add ins that don’t necessarily fit into the categories above.

  • Protein powder
  • Powdered milk
  • Honey
  • Oats
  • Instant breakfast
  • Coconut cream

The protein powder will add an extra boost of protein if needed. Honey will add some sweetness along with calories. And oats, while it may seem like a strange ingredient, will add some extra fiber and fun taste. You can use powdered oats, soak oats in liquid 10-20 minutes before blending, or even use raw oats if you don’t mind the texture (they will get ground and softer when you blend).

High Calorie Smoothies Pro Tip: Frozen juice

Tips for more calories: freeze juiceBefore I wrap up the post, I wanted to share a high calorie pro tip. Some people like their smoothies cold. Using frozen fruit is a great way to make a cold frozen smoothie. Some people use ice too. But ice is water. Water has no calories. Don’t use ice.

Instead, you can freeze juice in an ice-cube tray and use this for your smoothies. It will provide an ice-cold frozen smoothie and you won’t be wasting any volume. It will be jam packed with calories!

P.S. You can freeze milk or half and half too.

    1. Coconut milk has 75 calories per cup while oatmilk has 120 calories per cup. Read the nutrition labels, because some brands may have even more calories. I think if you like coconut milk, go for it! It sill has a lot more calories than unsweetened coconut milk (37 calories per cup). Best of luck!

  1. Hello
    This article is absolutely excellent and very much appreciated & I’m
    most grateful to have found it online! The high calorie smoothie
    recipes included are so helpful for
    me as I have not made smoothies
    at home. Presently I am trying to
    gain weight while dealing with a
    growing chronic health condition.
    Thank you for your wonderful and caring work!
    Kind regards,

  2. I don’t have half & half. What’s a high calorie alternative? I plan to make the peanut butter oatmeal smoothie.

  3. Thank you so much for these recipes! I have a dairy intolerance and stay away from whole fat milks, yogurts and creams. Would Oak milk and soya yogurt work as good alternatives?

    1. Yes! Oat milk and soya yogurt are great alternatives. Sweetened oat milks will have more calories than unsweetened. Soy milk is another higher calorie plant based option. One I don’t recommend for high calorie is almond milk. While delicious and a great plant based alternative, it is low in calories.
