Milkshakes are typically made from ice cream, milk, and added flavorings like syrup or fruit. They are very high in carbohydrates due to sugar from ice cream and added sweeteners. Standard milkshakes are not suitable for low-carb, keto, or diabetic-friendly eating or drinking. Low-carb versions can be made using sugar-free ice cream alternatives and low-glycemic sweeteners.
