Exercise weight spell

I need a spell that will make me lose more weight when I exercise. Like 1 pounds per minute... About that anyway. Should I just write it a spell? Or is there a spell that will already do that? Do not say it is impossible because I won't pay attention. I'm just looking for a working spell. Maybe 45 pounds in 7 hours? Or more. Thanks!!!(NO NEGATIVE ANSWERS!!!!!!!)

Sorry, no matter how much you try, such spells will not and cannot work. Nor would it be healthy for you if you did. While magic can help you with motivation to lose weight it will not make you instantly drop the pounds. The only way to do that is through proper nutrition, portion control, and regular exercise.
