Some people can take part in a ketogenic or keto diet to maintain a moderate weight or reduce body fat. The diet limits carbohydrates so that the body uses fats for energy instead, in a state known as ketosis.

According to a 2020 review, the ideal ratios for macronutrients on a keto diet are:

  • 55–60% fat
  • 30–35% protein
  • 5–10% carbohydrates

On a 2,000 calorie per day diet, this means limiting carbohydrates to 20–50 grams (g) per day.

Smoothies are an ideal way to include nutrients in the ratios that someone needs for a keto diet. Additionally, people can add foods, such as spinach, kale, and berries, which contain essential vitamins and minerals.

People could also add medium-chain triglycerides (MCTs) to increase the ketogenic effect. They can also add other supplements such as collagen or protein powder.

Below is a selection of smoothie recipes suitable for keto diets.
