Thermogenic product for weight loss works?

I want to take a thermogenic product, it was recommended to help accelerate my metabolism, which is very slow, I can not lose weight, I work out six months and I still can not lose more than 2 kg, it decreases in food, but I do not lose I wonder if these thermogenics really work.
Expert answer:

For those who produce and sell these products work well (give profit), for those who use do not work much. Seek a doctor, there are good medicines released for the treatment of obesity
