High Calorie Pineapple Smoothie for weight gain.


Because pineapple doesn't count among the fruits with the most calories, it is an inefficient fruit for people who want to gain weight.

But, pineapple is one of the most popular fruits in the United States, according to USDA data.[1]

Therefore, many persons looking to increase their body mass would like to integrate this exotic fruit also named ananas into their diets. One convenient way to do it is to mix pineapple with other more nutritious ingredients into a high-calorie smoothie, just like we did with our pineapple smoothie tailored for weight gain.

As expert creators of weight gain smoothies, we put together the recipe for the High-Calorie Pineapple Smoothie by using our guide for making high-calorie smoothies, a process verified by registered dietitian Iulia Serban.

In addition, to help you follow the recipe, we purchased the required ingredients, blended them, and illustrated the entire process with photographs.

Smoothie's calories

The standard version of the High-Calorie Pineapple Smoothie yields one serving of 568 calories. If you need more calories from the smoothie, however, you can adjust ingredient quantities by following these guidelines:

  • For 1000-calorie smoothie: multiply ingredient quantities by 1.76;
  • For 1500-calorie smoothie: multiply ingredient quantities by 2.64;
  • For 2000-calorie smoothie: multiply ingredient quantities by 3.52.

Ready? Let's explore the recipe.

Equipment

To prepare the High-Calorie Pineapple Smoothie, you need three pieces of kitchen equipment:

  • Blender
  • Knife
  • Scoop (for protein powder)

Ingredients

Ingredients of High-Calorie Pineapple Smoothie.
  • 10.6 oz (300 g) pineapple
  • 1 oz (28 g) cashews
  • 1 scoop (1.13 oz or 32 g) rice protein powder
  • 6.76 fl oz (200 ml) pineapple juice

Role of each ingredient

Each ingredient in the High-Calorie Pineapple Smoothie has a specific role.

Firstly, pineapple and pineapple juice are the ingredients that give a pineapple flavor to our smoothie.

Secondly, cashews have the responsibility of increasing the total calories of the smoothie without affecting its pineapple taste too much.

Furthermore, rice protein powder has the role of boosting the smoothie's protein content. We didn't use whey protein powder because, as confirmed by an Indonesian study on the combination of pineapple juice and milk, the mixing of bromelain found in pineapple with milk proteins results in a bitter taste.[2]

Ingredient substitutions

If you have a nut allergy, you can replace cashews with seeds, like flaxseeds or chia seeds.

Instructions

1. Adapt ingredients to blender size

Think whether all the ingredients will fit inside your blender.

If you use a small blender with a capacity of less than 560 ml (18.9 fl oz), break the ingredients into two or more identical portions, then follow the next instructions for each of them individually.

2. Add ingredients

Adding ingredients of High-Calorie Pineapple Smoothie in a blender.

Add the ingredients to the blender making sure pineapple juice ends up at its bottom.

If you own a blender with an ingredient recipient that installs upside down on the blender, always add pineapple juice lastly. This way, the blades will work smoothly without clogging in other ingredients.

3. Blend

Ingredients of High-Calorie Pineapple Smoothie: unblended vs. blended.

Blend the ingredients until the smoothie develops a fine texture (about 30-60 seconds).

If you own a less powerful blender, you may need to mix the ingredients for longer than 1 minute. Still, to prevent overheating your blender, abide by the recommended blending duration in your blender's manual.

4. Serve

Pouring the High-Calorie Pineapple Smoothie in a glass.

Pour the smoothie into a glass or a shaker bottle, and serve.

Regarding its taste, the High-Calorie Pineapple Smoothie has a pleasant pineapple flavor accompanied by hardly noticeable earthy notes of cashews and rice protein powder.

How to store

As a general rule, although we suggest drinking the smoothie right after blending it to have the best experience, you can safely store it in the fridge for about a day.
