This so easy is comical. Most overweight people do not move. You need to burn calories and take your lazy self to the limit. Start slow, drink water, eat healthy, and get your butt off the couch. You need to increase metabolism and that only comes with doing more activity than the body is used to. I know it might seem hard but if you can stay on a regimen, which are easily found on the net, you do not need a pill. Everyone looking for the easy fix. Easy is why you are fat.
I wish you the best, my best fix is to do an activity that is competitive. Tennis, racquetball, hoops or what ever. Always do something with someone else as it will make you push harder than if doing it your self.
Happy weight loss.
