I would say no it is not good. The sugar in slim fast can run its course at a to rapid pace. I had other clients that were diabetic and had a negative experience with slim fast. If you are looking to lose weight as a diabetic you need to be careful when choosing a weight loss program. A calorie based program is best. Strip That Fat is a good program that teaches you everything about foods plus you get a database that will plan meals for you based on foods you enter. It is a great program for people with medical conditions.
