I have been trying to lose weight but it's just not moving! I am 36 years old, 5ft 6 and weigh 13stone. Not sure what my BMI is. I have been eating a very low fat diet already, will Xenical still work even if I do not eat fatty foods to begin with? My doctor prescribed them today. I have had raised liver enzymes in the past so he is going to keep an eye on that. I really want to lose 2 stone in 3 months... Is this possible? I do excercise also.

Many thanks phoebes
