Any good detox/cleanse to kick-start losing weight? (10 POINTS + 5 STARS)?

I'm planning on losing a quite a lot of weight. I have done my physical and i am ready. I'm 160 pounds and want to be 135-106 preferably. I need a detox that is potent, and that will inspire me to lose weight more weight. I have changed my diet and i am going to the gym. something like a remedy of some sort :) Like a week cleanse (not a day cleanse)! Thanks (im 14 btw)
