What is the best detox/cleanse system to kick start weight loss for women?

I exercise regularly about 4 days a week lost a good bit of weight dropped from about 140 to 128 and built muscle. But just tried a complete body detox from gnc and its horrible! wish i would have read the reviews before i bought it. all it does is make you bloated as ever, gy, and even constipated!? i just want something to detox/cleanse me and hopefully really give a kick in the for that extra few pounds that needs to go and just to be healthier in general. i dont want something though that im strapped to the toilet for a day or two straight and cant do anything except go haha thank you!
