Like JGmma said, high interval training is excellent for fatloss. Only takes 15-20 minutes 3-4 times per week, and the fat will melt off...
Also, switch your macronutrient ratios up a bit. I changed my fiance's ratios, and she's been dropping weight for the past year. That's the only change she's made, and guess what? I actually increased her calories.
As far as fat burners are concerned, save your money. Even the ingredients that are supposedly "thermogenic" are highly overrated. The only time you should ever take a a fat burner is if you're on an extremely low caloric diet, and you need an energy boost.
Green tea extract is probably one of the most promising fat burners, yet you have to take it for 3-4 months to lose an extra 5 pounds or so..
