5 Delicious Smoothie Recipes Perfect for the Post-op Diet!

After weight loss surgery, a proper diet and nutrition need to be incorporated to ensure a healthy lifestyle and weight loss. Bariatric smoothies are a great option to make during or after the post-op diet.

Protein powder is a key factor in bariatric smoothies.

General Guidelines for Bariatric Smoothies and Shakes

Add at least one item from each category to create your smoothie. There are some important components of bariatric smoothies, along with other optional components.

Protein powder, fruit, protein base, and liquid are all important components of every bariatric smoothie. Additionally, spice, sweetener, and fiber also help as optional components.

Blending your smoothie fully is important for bariatric patients along with taking small sips.

The Ingredients/Components

Whey Protein Powder

Add one serving of your favorite types of protein powder.

The Protein Source

The protein source is the most important part of any bariatric smoothie. There are many great options, including soy milk, almond milk, fair life, skim milk, cottage cheese, or greek yogurt.

The Fruit

There are great fruit options for bariatric smoothies, although we recommend either fresh or frozen fruit. Some fruits include blueberries, strawberries, raspberries, pineapple, etc.

The Spice

Adding spices may or may not be needed for your post-op smoothie recipe. It all depends on your individual taste buds. If you prefer to add spice, some options are parsley, cinnamon, ginger, and nutmeg. Just a small pinch is probably the best starting point for flavor, then go from there.

The Sweet

Sweeteners may be needed for bariatric smoothies. If so, Splenda or Nutrasweet are your best options.

The Fiber

With constipation as a common problem after weight loss surgery, adding additional fiber can help! Some great sources of fiber include chia seeds, flax seeds, and psyllium husk.

There are so many different varieties of bariatric smoothies, make sure you find the combination you enjoy the most.
