All these carb blockers are a waste of money, in my humble opinion.

They generally block the good carbs, and won't block starchy and high glycemic food.

They also prevent you from staying away from unhealthy foods, and they intensify your craving.

I tried them, and never had any good results. And whenever a manufacturer claims that is has been "scientifically proven" but refuses to give reference to that study, you'll know something is "fishy"

Just my 2 cents.
