Peanut Butter Diet

Well I'm a girl and I want to lose about ten pounds a week, and I heard about this scheme peanut butter when you eat peanut butter only, can someone tell me about it ?? Thanks :):):)

Just a grilled peanut butter sandwitch whenever you're hungry, do it for one week and next week to spend sandwitch vegetables, keep alternating, just stretch your hunger as long as you can.
