What smoothies are good for weight gain?

While drive-thru smoothies, store-bought smoothie mixes, and pre-made shakes tend to be high calorie, they’re not always healthy! It’s best to make a homemade weight gain smoothie with minimal added sugar and nutrient-dense ingredients.

The best approach is to gain weight in a healthy way with high-calorie whole foods and nourishing ingredients.

The best foods to gain weight typically contain plant-based or animal protein, healthy oils and fats like nut butter, complex carbs, and full-fat dairy.

High Calorie Ingredients:

These high-calorie ingredients will quickly boost the calorie count of any smoothie! Here’s a few ideas to get you started:

a bowl of oats.
  • Chia seeds – One ounce of chia seeds has 138 calories, 4.7 grams of protein, and 9.8 grams of fiber! They’re full of antioxidants, essential minerals, and omega-3 fatty acids. They can go in ANY type of smoothie. Start with a tablespoon to see if you like the taste and texture.
  • Avocado – A medium avocado contains 240 calories and 25 grams of fat. Avocados taste delicious in a chocolate and peanut butter smoothie. They give it a luxuriously creamy texture.
  • Canned coconut milk – This ingredient really packs in the calories! One cup of canned coconut milk reaches 445 calories. This is a good ingredient to use if you need to gain weight quickly.
  • Oats – One cup of oats features 307 calories, plus they add a slight chew and oatey texture. Start with 1/4 cup, then move up to 1/2 cup if you like the taste and texture.
  • Nut butter – Nut butters of all types are high calorie and full of protein. Look for brands without added sugar.
  • Protein powder – Not all protein powders are created equal. Look for a brand with minimal added sugar and no additives.
  • Greek yogurt or cottage cheese – Unsweetened is best to avoid excess refined sugar. For the most calories, buy full-fat options.
