Honestly fat burners, regardless of how many claims they may make, won't target remove fat. Those stubborn areas are simply the last to go, decrease calorie intake and lose weight overall until they are gone. Fat burners will help with overall weight loss and help you in thus way. If I could recommend only one I would suggest you try alphamine, fantastic fat burner, helps maintain muscle mass during your cut, tastes amazing, and improves your mood which can be affected during a long term calorie deficit.
Aside from fat burners there are other potential options, such as reduce XT, if cortisol could be a factor.
