Most all good health stores and workout stores will have people there that can talk to you about that and help you out with a product. I know GNC stores here sell everything for everything for your body. Try Natural first !
Here are a few ways to boost your metabolism:
-Take green tea 2-3/day
-drink coffee (caffeine will increase your metabolic rate)
-Add spices to your food (cinnamon, hot sauce)
It would seem like you're looking for additional things to do though to help with weight loss here...which is why I'd also suggest you try out in addition to this: Intermittent fasting.
Fast for 14-16 hours a day, then get all your calories in the remaining hours of the day. You can have less than 50 calories during the fast without breaking it (ex: Coffee with a *little bit* of milk/sugar)...This will help you burn more fat. There are other tricks here as well..
