We wouldn’t advise on this. While the FAST Shakes are nutritionally balanced meal replacements they are not still not as good as real, whole foods which have so many beneficial and essential nutrients. These shakes are not designed for long term use. We have included them in the BT program as they provide you with a simple and convenient food option while we gradually introduce more nutrient dense whole foods back to the diet.
