Low-carb smoothies are blended beverages designed to minimize sugar and starch content, typically using ingredients like leafy greens, avocado, nuts, seeds, and low-glycemic fruits such as berries, often combined with unsweetened plant-based milk or water. They are a modern dietary adaptation popular in health-conscious and ketogenic communities worldwide, with roots in the broader smoothie culture that originated in the United States in the 20th century.
These smoothies are generally low in carbohydrates, moderate to high in healthy fats and protein, and rich in fiber, vitamins (like A, C, K), and minerals (such as magnesium and potassium). A typical serving ranges from 150 to 300 calories, depending on ingredients like nuts, seeds, or protein powders.
