Desperate

I am really desperate. I am gaining weight even though my food intake is lesser than before ( I think it is related to my age, which means I am getting old :( Anyway, one of my patient said that in order to have her surgery immediately she need to take a weight loss supplements twice a day and with a combination of 1 full meal a day. She said that for a span of 2 weeks she loss 10 kgs. What if I will try it? Do you think it will work for me? I hope so...
