You're not going to find a solution in a bottle or the medicine cabinet. It's really pretty simple, cut down on your caloric intake, do at least 30 minutes of intense aerobic exercise every day, minimize the consumption of meat, particularly red meat, avoid processed and refined (aka junk) foods and drink lots and lots of water (I only drink distilled water). Not only will your weight (% body fat) come down, but you'll be a lot healthier.
