These shakes have been designed to deliver all the components of a proper slow-digesting natural whole foods meal (Carbs, Proteins, and healthy Fats). When all 3 macronutrients are combined together, the Glycemic Index for the entire shake is lowered. This applies to all meals in your diet. This shake is good for everyone…those who have not worked out to those who had a very intense workout! These shakes are all about a 1:1 ratio with carbs : protein.
