Personally I think any sport will be good for you, choose one you like most, start from there and forget about fat burner... You gotta tune your body into a proper mode before even thinking of going short-cut... You gotta set your goal, type of body you desired, consult a fitness personnel to help you get to your goal.. It's a NO-NO for beginners to go for fat burner.. Check food intake, cut your carbs by half, and be sure drink 3-4 liters of water alone, will help you to lose weight.. Again it depends what you want...
