The problem with pills is, if they even work, eventually you will stop taking them. Then you gain it all back, plus more. I took Hydroxycut, and Dexatrim after h.s. graduation, and got down to 183. Felt great for a year.. 7 years later I was 361, and in E.R. for CHF. Two years later, I had my ICD ( inter-coronary device ) put in at 29 y.o.
At best it just delays the weight gain, and keeps you from learning how to control your diet. All pills have side effects.
People keep saying they only help temporarily, but that's not true.
They don't even work temporarily.
Most supplements are just caffeine (usually under three or four different names to hide how much there is) and capsaicin (the hot chemical in hot peppers.) The caffeine makes you jittery and the capsaicin makes your face feel hot, so psychologically you connect that sensation of heat with the word "burn," and you believe you're burning fat or calories. You're really not using any more calories, though, and you're putting yourself at a small risk of harm because there's no regulation on how much caffeine they put into each dose.
The prescription ones do work temporarily if you have some sort of disorder where you really do feel hungry when others don't. They work either like an anti-depressant or like an amphetamine to stimulate your nervous system so you think you're not hungry-- but they have the same side effects as other amphetamines or anti-depressants, including mood effects and high blood pressure. If you overeat for any other reason than hunger, those drugs won't work, and the people for whom they do work build up tolerance very quickly; after 9-12 weeks they just don't work anymore. They're really meant as a quick way to get super-obese people down to where they're not at immediate risk of dying from their obesity, or to where they can survive bypass surgery. They're not for people who just need to lose a little weight to look and feel better.
- they are over priced - they are an excuse for those who do not wish to try and change their habits - while they may work temporarily (maybe), they are not a long term solution, and do nothing to help a person learn proper eating and exercising lifestyle changes - they are likely unsafe, but I don't have personal experience to back up this thought
