I have struggled with weight loss from early childhood. A few months ago I was diagnosed by my doctor with insulin resistance. I was put on metformin and for the last couple of months xenical too. Xenical was to help with the weight loss as I was fast heading down the depression route as I couldn't lose weight no matter what. I am also following the slimming world method too. My big problem is that since starting xenical the weight loss has been very very slow and last week I even put on half a pound. I haven't had any side effects at all, so I am beggining to wonder if xenical is doing anything at all. I am 90% of the time on a very low fat/virtually fat free diet. Could that be the problem? Any advice would be hugely appreciated. Thanks:break_diet:
