Is it possible for me to lose weight?

Set an achievable goal for your weight reduction. If the aim is not practical then you will easily get disheartened and stop following your regime. You must set a target that has a time limit. The amount of weight you want to lose and the time within which you would like to lose it should be decided beforehand. If the time and amount of weight is clearly decided primarily, then your enthusiasm will keep you on the track until you reach your destination.
