Is there any supplements that has no side effects which makes slim . im so fat?

No: None of them work. I think every physician on healthtap will agree that health doesn't come from taking pills. The key is going to be a change in lifestyle -- eating less, exercising more. This in turn will require you to develop new friends and new pursuits -- i.e., it will take courage. You have it. If you are very overweight, consider bariatric surgery early if offered by your physician.

No magic pills but..: I do not know any pills that will magically make pounds melt away without a healthy diet & exercise, but supplements may help if combined with diet & exercise. See http://www.Lef.Org/magazine/mag2011/jul2011_shed-pounds-by-inhibiting-cellular-fat-storage_01.Htm, also consider saffron, green coffee extract & fucothin. See http://www.Drfuhrman.Com/weightloss/default.Aspx for a good diet to follow.
