Although many fat-burning remedies exist on the market these days, many of them are bunk. Commercials full of 'do it yourself' methods are skanky at best, and going to the gym, eating healthy, and getting the body you want over time are DEF out of the question. Really, the only SURE-CURE for getting rid of that pesky waist-side fat would be the one and only.... m-e-t-h
Considering the only downsides include loss of teeth, affinity for addiction-fueled prostitution, and an inability (although one of the upside effects in this case) to sleep, the pros are beyond my limited ability to even count. Considering the large amount of water-weight you will dispel in the first few minutes after getting jacked up, coupled with your obviously unwanted desire to do it the socially acceptable way, this should be right up your alley.
The best places i have found to cop said 'supplement' would be small children in the project district (rarely citizen marshalled by local law enforcement), bareback sex parties at 5am at some closeted republicans after-hours party in his liberal but go-with-the-flow's mothers basement, or, if you're feeling really lucky, the rarely-wiped anus of a freshly 'liberated' yugoslavian illegal alien immigrant, being set free on the street of NYC in the dead of winter. This man will probably charge the most, but i promise you, the shit they cook in his homeland will have the most weight-loss properties per ounce that you desire.
Or lypo. That might work too.
