Keto Viante -: Though short, I am going to cover the people that would say that smoothies are not healthy. If you are on low carb diets than smoothies are a nightmare. Yogurt, milk (medium carbs and protein, so not bad), fruits; full of carbs and sugars. If you are on any Atkins or where to buy 7 keto, than this will be awful for your body. While the sugars are seen as good by many, and you will be getting a good variety of vitamins and antioxidants, you can get the same from vitamin pills.
