We need to know more about you before we can give any advice...we need to know your age, weight, gender, height, exercise level, etc.
Don't bother with the South Beach Diet, if you lose any weight at all you're going to end up gaining it back double when it's over. You don't need a gimic and there's no quick fix if you want to lose it and keep it off. Not trying to be harsh but that's the reality no matter what the fancy ads try to make you believe!
