11 High Calorie Smoothie Recipes for Weight Gain – The Healthy Way

Whether you’re looking to build muscle or gain weight for medical reasons, we’re here to get you up and running TODAY.

First of all - here’s what not to do:

It might be tempting to just eat everything - fast food, ice creams, foods rich in unhealthy fats, and added sugars…

Yes, they might cause you to gain some pounds, but you’ll also invite short and long term health damages.

I tried it and ended up feeling tired, total lack of energy, and constantly suffering digestion issues.


It can be almost impossible to find the time (and inclination!) to eat enough of the right foods to get the calories needed to significantly bring your weight up.

When I wanted to finally say goodbye to my skinny look, smoothies came up as one of the easiest solutions, while also being fun to drink.

In this post, you’ll find my 11 delicious recipes for smoothies that will help you do the same.

You'll also learn to choose smoothie ingredients that help you achieve your nutritional goals in the healthiest way.

How Smoothies Can Help You Gain Weight

The key is to use nutritious ingredients that are dense in the number of calories and also provide additional health benefits:

  1. In a blender, process 2-3 fruit portions and 2 vegetable portions. Recommended: banana, mango, avocado.
  2. Add a cup of nuts and seeds. These contain a considerable dosage of healthy fats, which translate into additional calories and a host of health benefits.
  3. Optional: add protein powder or weight gain shake - for extra calories, high protein, and taste.
  4. Add 1 cup of whole milk - you can also use full-fat yogurt or soy milk.

Reasons for Weight Gain

There could be a variety of reasons you'd want to do that:

  • You want to build up more muscle, get stronger, become more athletic and supplement your sports nutrition regimen.
  • Chronic illness or other health conditions, might result in you losing weight or having a significantly decreased appetite. This can include hyperthyroidism, diabetes, digestive issues such as inflammatory bowel disease (IBD) and depression
  • At its simplest, it could be that you’ve lost more than you anticipated when you stopped eating unhealthily and now you need to put a bit back on, as happened to me.

How to Gain Weight the Healthy Way

To gain weight in a healthy way, you need to consume more calories than you burn off.

Putting on weight isn’t about eating as much as you can and of whatever you like, though. A lot of people do go down this road, but there is a right and wrong way to add those pounds. Opting for fatty and sugary foods and junk food is a very unhealthy way to do it.

Here are the easiest, most popular healthy options you can choose:

  • Incorporating high-calorie foods into your diet that are healthy too. Ideally, these will be calorie-dense but also contain lots of vital nutrients. Protein and healthy fats should be your priority, and you can boost your calorie intake through foods that are rich in these.
  • Making smoothies that incorporate high-calorie ingredients - this is one of the easiest and healthiest options.

Whatever option you choose, you want to have a gradual gain, at a pound or two per week, rather than all at once.

If your reasons for wanting to put on weight are on medical grounds, it’s best to consult a medical professional before you start.

Why Smoothies and Shakes are Great for Adding Extra Pounds

Because smoothies are such an easy way to consume calories, they’re perfect for packing more into your day.

Let’s face it; it’s far easier to drink several of those high calorie shakes over the course of a day than to fit in the equivalent amount of “whole” foods - especially if you’re on the go a lot.

You can potentially consume thousands of calories just by drinking smoothies, and best of all, downing them takes a lot less time than cooking and chewing the same foods!

Smoothies are a particularly good option if you don’t have a great appetite as they can be easier to tolerate than whole foods.

The trick is to make sure that your smoothies are full of healthier types of foods, rather than sugary ingredients.

Which Foods Can Help You Gain Weight Healthily?

We've rounded up the healthiest foods to include in your smoothies, that will also help you to gain weight effectively:

#1 Avocado

Picture of the two avocados in the white zinnia

Avocado is full of heart-healthy unsaturated fats, which is why you’re advised to limit portion sizes under normal circumstances. It has tons of additional health benefits.

When added to smoothies, avocado gives a deliciously creamy texture and goes well in lots of different combinations.

#2 Nuts

Nuts contain quite a lot of healthy fats, which unsurprisingly translates into calories too. Some nuts are more calorific than others. Most nuts also contain a good amount of fiber, including almonds.

You can blend nuts into your smoothies or use them in butter form, such as almond or peanut butter, to get the same benefits.

#3 Seeds

Chia, hemp, and flax seeds are a great source of protein, healthy fats, and calories while also offering nutritious benefits. Hemp and chia seeds, in particular, have a good amount of fat, fiber, and protein.

#4 Coconut Oil

Coconut oil contains saturated fats and has had bad press because of this. In fact, 90 percent of it is saturated fat! But this isn’t nearly as unhealthy as it may sound. Coconut oil is now considered to be something of a superfood due to its benefits for health.

The fat content is mostly fatty acids, and studies have shown that people who consume a lot of coconut oil are actually really healthy!

#5 Oats

Picture of oats

Like most whole grains, oats are calorie-rich and also contain a good amount of fiber. They contain more protein and fatty acids than most whole grains.

#6 Full Fat Dairy

Full-fat milk and yogurt are full of protein and fat. They can be a much healthier option than alternatives.

#7 Protein Powders

If you need a bit more of a helping hand in getting protein into your diet, protein powders are an ideal way to do this. They work best if you want to build muscle through workouts.

You can either go or Whey or plant-based protein powders, depending on your nutrition preferences.

Eat More Frequently

Another healthy way is eating more frequently. Underweight people tend to fill up and feel full much faster. It is best to eat five to six smaller meals throughout the day instead of two to three larger meals.

Go for the Nutrient-Rich Foods

When eating these small meals throughout the day, you also want to reach for those nutrient-rich foods, including whole wheat breads, pastas, cereals, fruits and vegetables, dairy products, lean proteins, and nuts and seeds.

Treat Yourself

Throughout your journey, you should never forget to treat yourself so it would keep you motivated. However, you want to be very aware of the sugar and fat you are consuming.

Make sure there is some kind of nutritional value that can go along with those added calories. Yogurt bars, for example, are a great choice and would go well with a delicious smoothie for a quick snack and treat, without spiking your blood sugar level.


Exercise is important whether you are trying to gain or lose weight. Strength training is especially important and can help you put on some pounds by building up your muscles and muscle mass. It is also a good way to get your appetite going.

Consider Your Drink Choices

You should also watch what you are drinking as well as watching what you eat. Some people sip on beverages before and during a meal but doing this can actually hurt your appetite. Instead, drink higher calorie beverages with a snack or 30 minutes after a meal instead of with the meal.

When choosing your drinks, try to avoid diet sodas, coffee, and other drinks that have fewer calories and no nutritional value. This is when you should consider drinking high-calorie smoothies to help you with your weight gain.

  • 1 cup nut milk, e.g. almond milk
  • ½ avocado

2. Mega Calorie Smoothie

For those days when you really need to boost your caloric intake quickly and easily, this smoothie contains a whopping 2000 calories!


  • 2 cups of milk
  • 2 bananas (can be substituted for ½ avocado)
  • 2 scoops protein
  • 1 cup ice cream (preferably similar flavor to the protein powder)
  • 2 tbsp olive oil
  • 1/2 cup oats
  • 4 tbsp peanut butter


  1. Soak the oats before blending them.
  2. The protein powder and peanut butter should be added to the blender after some of the other ingredients have gone in to avoid them getting stuck to the bottom and being difficult to blend properly.

Note: You can make this smoothie recipe less calorie dense by swapping out the ice cream and replacing it with more frozen banana. This will give the same creamy consistency for days when you don’t need to be consuming 2000 calories in one smoothie.

3. Avocado & Berry Yogurt Smoothie

This deliciously creamy smoothie is full of protein and dairy to help you to put on weight in the right way, while pampering your taste buds!


  • ½ avocado
  • ½ cup plain Greek yogurt
  • 1 tbsp chia seeds
  • 1 tbsp coconut oil
  • ¼ cup berries
  • ¼ tsp cinnamon


Blend all of the ingredients together until creamy and smooth.

4. Walnut Protein Smoothie

Picture of the four walnut

This protein-rich smoothie recipe builds on the rich taste of raw or baked walnuts. The fruits add vital nutrients.


  • 1 scoop protein powder
  • 1 cup walnuts
  • 1 cup spinach
  • 1 banana
  • ½ avocado
  • ½ apple
  • 1 tbsp coconut oil


  1. Soak the walnuts in a small bowl of water for about 30 minutes
  2. Add all of the ingredients to your blender
  3. You may need to blend a little bit longer to ensure that the walnuts are fully blended. If you don’t mind nutty bits in your smoothie, you can just blend for a shorter period of time

5. Oat Protein Smoothie

This smoothie is packed full of protein, and the combination of yogurt and banana adds a gorgeous creamy consistency.

Check out this plain greek yogurt-based smoothie!


  • 2 cups whole milk
  • 1 ½ cups oatmeal
  • 2 scoops protein powder
  • 1 cup plain Greek yogurt
  • 2 tbsp almond butter
  • 1 tbsp coconut oil
  • 1 banana


Blend everything together until smooth and creamy. If you like your shakes chilled, add 2-3 ice cubes. 

Yummy recommendation: add one drop of vanilla extract, preferably natural and organic such as this one.

6. Vegan - Paleo Protein Smoothie

You can enjoy the benefits of protein-rich smoothies even if you’re on a vegan or paleo diet and don’t drink animal milk products.


  • 1 banana
  • 2 tbsp coconut oil
  • ½ cup mixed nuts
  • 1 scoop protein powder
  • 1 cup coconut milk (nb: ½ cup if you want fewer calories)
  • 1 cup almond milk
  • Optional: 1 teaspoon maple syrup


  1. You may prefer to blend the mixed nuts before you put everything else into the blender.
  2. The protein powder shouldn’t be added first as it is likely to collect at the bottom of the blender and not mix properly with the other ingredients.

7. Berry, Banana & Oat Protein Smoothie

Picture of the blueberries and raspberries in small containers

Berries are full of healthy antioxidants. Oats and protein powder add some all-important protein too!


  • 1 cup oats
  • 1 cup whole milk
  • ½ cup raspberries
  • ½ cup blueberries
  • 2 bananas
  • 1 peach
  • 2 scoops of protein powder


  1. You may want to blend the oats first so that it’s easier to create a smoother consistency.
  2. Add all other ingredients to the blender and blend until the mixture is smooth.

10. Strawberry, Banana & Peanut Butter Smoothie

Picture of the strawberry, banana & peanut butter smoothie in the glass with the strawberry on the edge of the glass and straw in it

The amount of protein in this smoothie is perfect for our goal!


  • ¾ cup plain yogurt
  • 5 large frozen strawberries
  • 1 banana
  • 2 tbsp organic peanut butter
  • 2 tbsp full-fat milk


  1. Add the milk, yogurt, and banana to the blender and blend.
  2. Add the peanut butter and strawberries and blend everything until smooth.

NB: If you’re not a big fan of nuts, you can make a Strawberry & Avocado smoothie by taking the peanut butter out of the recipe.

11. Banana & Peanut Butter Smoothie

Picture of the banana and peanut butter smoothie in the glass on the red textile

If you don’t feel like a berry-based smoothie, here’s one that still has lots of fiber and protein!


  • ¾ cup plain yogurt
  • 2 tbs peanut butter
  • 1 banana
  • 1/8 cup milk
  • ¾ cup ice (optional)


  1. Add the yogurt, banana, and milk to the blender and combine.
  2. Add the peanut butter and blend everything until smooth.
  3. If desired, add the ice and blend again.


  • It’s best to drink your smoothies straight after you make them. If there’s too much, you can keep them refrigerated for a few hours and have it later.
  • Adding seeds to your smoothies is an easy way to include a good range of nutrients.
  • Yogurt is a great option in smoothies as it provides fats, probiotics, and calcium for weight gain and general health.
  • If you’re lactose intolerant, you’ll want to avoid whey protein (which comes from milk) as well as milk itself. Use plant-based protein powder instead.
  • Remember that your weight gain should come from nutritious foods that also contain a lot of calories, rather than unhealthy foods that are likely to increase your cholesterol levels along with your weight.

Other Foods to Help with Healthy Weight Gain

In addition to all the delicious foods above to include in your smoothies, there are a few other items you may want to have on hand for your journey:

Nuts and Nut Butters

Even one small handful of almonds can provide you with over 7 grams of protein and a ton of healthy fats. They are very calorie-dense and can add calories when needed.

They can be added easily to your smoothies, yogurts, and other snacks and meals. However, keep an eye out for those with added sugar and extra oils. Those are the ones you will want to stay away from. Always check the ingredients list carefully, and only choose the ones that have a single ingredient, such as this one (100% almonds).


This is a low carb source for weight gain and is easy to make. It can also be conveniently added to other proteins to create a well-rounded meal quickly before you head out the door - even if it is just the microwaveable rice.

Rice can also be made ahead so you can prep your meals throughout the week.

High Protein Smoothies

It is always best to make your own smoothies rather than purchase the commercially manufactured smoothies, so you know exactly what it is you are consuming. You also have full control over the flavors.

The recipes on this page are perfect for that! Depending on the type of high protein smoothie you choose from the many recipes above, you may be able to gain an extra 400-600 calories to go alongside a healthy portion of protein and a high amount of essential vitamins and minerals your body needs.
