Hi jokhan,
The forum doesn't advise on which are good or bad diet plans. However, members are free to give you their own opinions and to tell you what has worked for them.
My own personal view (and I emphasise its a personal view) is that I wouldn't go near either of them. Having just looked them up online I see that they are both based on little or no fat but a high amount of carbohydrates. As it is carbs that, as a diabetic, your body struggles to cope with, pumping it full of soluble starch, which appears to be the basis of both diets, would most likely send you blood sugars rocketing. It will also fill you up, but the problem with most starches is that a couple of hours later, you are hungry again.
As Lenny has said, a far simpler way, and a lot cheaper than any of the proprietary slimming brands, is to simply reduce the amount of carbohydrates in your diet. Have a good look round the various forum threads and you will find a great deal of information on what has worked for others.
