Maple Syrup Diet

I heard about the maple syrup diet which supposedly helped Beyonce lose 22 lbs. Ms Karen Davila, a news anchor in the Philippines swears by this as well. I'm so curious that I want to try it. I got all the stuff for it but at the moment I only weight 6st 11lbs so it's not a good time. If I gain weight I would try it just to see if it's just another fad diet.
