I can tell you, without knowing anything else besides looking at magnetic-diet.com that it's a scam. The website starts with the premise that low carb diets are not sustainable and that you constantly crave carbs when you're on low carb diets. This is just not true. It talks about how it's superior to low calorie diets, it's axiomatic that if you burn more calories than you take in, unless you have a medical disease, you are going to lose weight. Anyone who claims otherwise is just lying. Why would someone lie about other diets? Because telling the truth would hurt them, they know there is medical and scientific evidence that supports low carb dieting and low calorie dieting. There is no medical support for magnetic dieting, which makes me wonder how good it can be.
Try one of the low carb diet plans if you're serious about losing weight, atkins, south beach, etc. . . .Good luck.
