The 10 Best Keto Smoothie Recipes

The ketogenic eating plan focuses on drastically cutting carbohydrates and deriving the majority of calories from fats.

It’s used to help children control epilepsy and has also been associated with weight reduction, improved blood sugar regulation, and lower cholesterol.

Because the keto approach restricts carbs, smoothies made with high-carb ingredients like fruit, yogurt, honey, and milk aren’t typically compatible. That can be a problem for people who depend on smoothies as a quick, nutritious breakfast or snack.

Luckily, there are plenty of low-carb, nutrient-dense smoothie options that fit within a ketogenic framework.

Below are 10 top keto smoothie recipes that keep carbs low while emphasizing healthy fats.

1. Triple berry avocado breakfast smoothie

Berries — such as strawberries, blueberries, and raspberries — tend to have fewer carbs than many other fruits. They’re also high in fiber, an indigestible carbohydrate that supports gut health.

Because fiber isn’t metabolized the same way as digestible carbs, people on keto frequently subtract fiber grams from total carbs to estimate net carbs (7, ).

Berries have low net-carb counts and can be included in moderation on keto.

This triple berry avocado smoothie contains 9 grams of net carbs and is satisfying enough for breakfast or a snack. To prepare one portion, blend:

• 1 cup (240 ml) water
• 1/2 cup (98 grams) frozen mixed berries (strawberries, blueberries, raspberries)
• half an avocado (100 grams)
• 2 cups (40 grams) spinach
• 2 tablespoons (20 grams) hemp seeds

Nutrition Facts

2. Chocolate peanut butter smoothie

Zucchini is a summer squash rich in fiber and vitamin C, a water-soluble antioxidant that helps protect cells from damage linked to heart disease and other conditions.

Mixing lemon juice and high-fat milled flaxseed with cucumber yields a refreshing keto smoothie with just 5 grams of net carbs.

Some studies suggest that full-fat dairy might be associated with benefits such as lower blood pressure and triglycerides, plus a reduced risk of metabolic syndrome and heart disease, though more research is needed.

Heavy cream is low in carbs and contains very little lactose (milk sugar), so this indulgent smoothie works well on keto.

To make one serving with 8 grams of net carbs, blend:
