hmmm.. I am hoping to lose 70 pounds in 4 months but I really doubt its possible... you can only do SO much honestly... work out like CRAZY! get "The Firm" everyone I know who has done that has beautifully toned muscles in weeks... it's TOUGH though and you have to do it every day! You should do cardio 5-6 days a week also..before the firm. Stick to induction adn no cheats.... There's now way you can guarantee that loss but if you do all of that you are bound to look pretty darn good in 3 months
