Of all of the success stories about Carb Nite, I have one of the most unusual. My 80 year old grandmother is an insulin dependent diabetic who has gained a lot of weight in the last two years. Four weeks ago she started a modified version of Carb Nite and in this time has dropped about 15 pounds and has lowered her insulin dosage by 20 units per day. This program might just give her another 20 years!
