The Keto Lemon Blueberry Smoothie is a refreshing, creamy, and vibrant low-carb drink that perfectly balances bright citrus notes with the natural sweetness of blueberries—all while staying fully keto-friendly. Smoothies are often considered off-limits on a ketogenic diet due to their reliance on bananas, honey, dates, or other high-carb fruits. However, with the right ingredients and careful portion control, smoothies can absolutely be part of a healthy keto lifestyle.
This smoothie is inspired by the classic lemon-blueberry flavor combination, often found in muffins, cakes, and desserts. Here, it’s transformed into a nutritious, sugar-free smoothie that delivers freshness, creaminess, and satisfaction without spiking blood sugar levels. The lemon adds a zesty, refreshing kick, while blueberries—used in moderation—provide antioxidants, color, and a subtle fruity sweetness.
What makes this smoothie especially keto-friendly is the inclusion of healthy fats such as heavy cream or coconut cream, which slow digestion and help maintain ketosis. The result is a smoothie that’s not only delicious but also filling and energizing, making it perfect for breakfast, a post-workout refreshment, or a light dessert.
Whether you’re new to keto or a seasoned low-carb eater, this Keto Lemon Blueberry Smoothie proves that you don’t need sugar or high-carb fruit to enjoy bold, refreshing flavors.

Keto Lemon Blueberry Smoothie
Ingredient Notes
Unsweetened Almond Milk
Unsweetened almond milk is an excellent low-carb base for keto smoothies. It has a mild flavor, low calorie count, and typically contains only 1–2 grams of carbs per cup. Always choose unsweetened varieties and check labels to avoid hidden sugars.
Heavy Cream or Coconut Cream
These ingredients provide the fat content necessary for ketosis and help create a creamy, milkshake-like texture. Heavy cream gives a rich, classic flavor, while coconut cream is ideal for dairy-free or paleo keto versions.
Blueberries
Blueberries are one of the lowest-carb fruits available, but they must be used in moderation on keto. A small portion adds antioxidants, fiber, and natural sweetness without pushing carb intake too high. Frozen blueberries also help thicken the smoothie.
Lemon Juice
Fresh lemon juice adds brightness and acidity, balancing the richness of the cream. It enhances the blueberry flavor and gives the smoothie a refreshing, clean taste.
Lemon Zest
Lemon zest contains aromatic oils that intensify lemon flavor without adding extra carbs. It’s a key ingredient for achieving a bold citrus taste.
Sweetener
Powdered erythritol or monk fruit sweetener blends seamlessly into smoothies and provides sweetness without calories or blood sugar spikes. Adjust the amount based on taste preference.
Vanilla Extract
Vanilla extract rounds out the flavors and adds a subtle dessert-like warmth that complements both lemon and blueberry.
Chia Seeds or Flaxseed Meal
These are optional but recommended for added fiber, omega-3 fats, and thickness. They also help keep you full longer.
Ice
Ice gives the smoothie a thick, frosty texture and makes it more refreshing, especially in warm weather.
