There is no product on the market that can guarantee what part of your body will lose weight.
The medical evidence for things like this product is at best weak and usually no better than blind placebo tests. Save your money and put it towards a good pair of walking shoes or such which will do you greater benefit in the end.
I make my living as a magician. I know all about the art of the con. The reason why cons work is because the victims WANT it to work. Desire always overrides the facts. Sorry...there are no short cuts.
If such a worthy product could do all that the weight loss industry promises you wouldn't need a review...the inventors will be winning a Nobel Prize and every newspaper in the world would be singing its praises.
Weight loss is about developing a healthy workable lifestyle.
