High-calorie banana smoothie for weight gain - featured.


If you love banana smoothies but you don’t know to make them high-calorie, you are missing out on a huge boost in your daily efforts to gain weight. What's worse is that if you drink low-calorie banana smoothies, you hurt your ability to gain weight by filling up your stomach and not leaving space for other high-calorie foods and calorie-dense drinks.

From recipe creator's experience: I drink high-calorie smoothies daily and I almost always include bananas among the ingredients I use because I love their taste and I know they supercharge my energy levels.

Happily, from today on, you will be able as well to prepare high-calorie banana smoothies for weight gain by following our dietitian-approved recipe, which counts among the best high-calorie smoothie recipes.

In terms of calories, the main version of this banana smoothie has about 1000 calories (989 specifically) but this number can be modified, depending on your needs. To do so, you just need to adjust the portion of each ingredient by following these instructions:

  • For 500-calorie banana smoothie: use half of the ingredients in the recipe;
  • For 1000-calorie banana smoothie: don’t modify the ingredients;
  • For 1500-calorie banana smoothie: multiply the ingredients by 1.5;
  • For 2000-calorie banana smoothie: double the ingredients.

Equipment

Equipment needed to make high-calorie banana smoothie - blender and spoon.

To make this high-calorie banana smoothie, you need these kitchen tools:

  • Blender
  • Spoon

Ingredients

Ingredients needed to make high-calorie banana smoothie for weight gain.
  • 4 medium (472 g) bananas
  • 6 oz (300 g) 2% fat Greek yogurt
  • 1 oz (28 g) cashews
  • 1.8 oz (50 g) oats
  • 10.2 fl oz (300 ml) water

The main ingredients of this high-calorie banana smoothie are obviously bananas. They give the smoothie a thick consistency, whether you use unripe, ripe, brownish, or frozen bananas.

Sliding to the second ingredient, Greek yogurt adds texture to the smoothie along with a significant number of proteins.

Furthermore, cashews are in the mix because they pack many calories and healthy fats. Moreover, this type of nut has a neutral flavor that won't modify the banana flavor of the smoothie.

Next, oats bring extra carbohydrates to the smoothie, thus more calories.

Last but not the least, although it has zero calories, water accomplishes the important task of thinning the smoothie, so you don't end up with a thick paste.

Instructions

1. Peel the bananas and break them so they will fit in the blender.

2. Think whether all the ingredients will fit inside your blender.

In case you have a smaller blender, like the one we used for this recipe, split the ingredients into 2 or 3 equal portions, then follow the instructions for each portion separately.

3. Add all the ingredients to the blender, making sure the water is at the bottom of the blender.

If you have a blender with an ingredient recipient that needs to be turned upside down when installed on the blender, always add the water lastly. This way, the blades will work smoothly instead of clogging in other ingredients.

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

If you have a weaker blender, you may want to mix the ingredients for longer than 1 minute. Nevertheless, to avoid overheating your blender, respect the blending time recommendation in your blender's manual.

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

Nutrition facts

  • Volume: 40.6 fl oz (1.15 l)
  • Calories: 989
  • Protein: 42 g
  • Carbs: 163 g
  • Fat: 25 g

Having almost 1000 calories, the high-calorie banana smoothie is the drink with the second most calories in our list of weight gain smoothies.

Even though the high-calorie banana smoothie has just a few ingredients, it sports a high level of carbs, a decent amount of fat, and enough protein to replace pre-workout meals for muscle gain, which is great considering that this high-calorie smoothie is made without protein powder.

Most of the carbs of the smoothie come from bananas, which are one of the fresh fruits with the most calories and the 2nd best fruit in the ranking of weight gain foods for females. Oats, however, also bring a fair share of carbs to the smoothie.

The 2% fat Greek yogurt contributes the most to the smoothie’s protein levels while the smoothie’s fat comes mainly from cashews, which count among the high-calorie nuts.

Since this smoothie has only 22% of its calories coming from fat, it joined our list of low-fat high-calorie foods.
