I have type 2 diabetes and as a result have to eat a carb free diet to keep my weight down. This kind of diet appeals to me as I am always looking for a new carb free diet to follow to change things up and i like the shakes to this diet. But i have to agree with the majority of the feed back above, the price is crazy for 4 weeks! You can do the same thing with a lean protein shake for about R250 and following a carb free diet. I’ve lost 16kgs over a year and I am 5kgs away from goal.
