people do strange things to loose weight?

I have read a few stories about people detoxing to loose weight?

WHY and what do they do this for? Like they go on some 7/10 days of weird water drinks and eating binge.

I have never had to detox my body. I just STOP eating whats bad.

AND whats with a colonic? Am i spelling that right? WHO in the heck goes to get one of these too loose weight and why?
I have no problems going to the bathroom. LOL None. So i dont have a build up. IS that what they are doing when they get a bowel cleansing?? Ewwww

WHY do they do that?? Thats gross. lol

If you eat right and work out TRUST ME YOU get your own BOWEL cleasings with in the first 3 weeks lol. SO I dont get it. Why do they do that?

I noticed on YOU ARE WHAT YOU EAT they do that ALL the time......WHY!!!?????
