losing weight appropriately does not involve the descriptive words "easy" or "quickly". i'm sure there are gimmicks out there you can ingest that will rid you of several pounds quickly, but the weight you lose will be water weight, not fat. furthermore, the backlash you will suffer as a result will probably make you gain fat afterwards.
the body only loses fat at a certain rate. if you diet too strenuously and eat too little, your body/metabolism slows down because its defending against starvation. your fat will burn more slowly. there is no fast, easy way to lose fat weight. if you want to lose water weight, thats fast, easy, and extremely unhealthy.
