reduce my weight

My current weight is 51++kg. This week had been with me for more than a year. I had been trying to get rid of at least 2kg, however till now my mission still unsuccessful. I wonder whether any best fat burners work for me or not. There are so many type of fat burners can be found in the market now. At times, I am so tempted to try one of them. But my hubby stops me from taking them. To him, exercises are the best ways to reduce extra fat, other than control our food intake. Again, it is easy said than action.
