I was seriously considering if i could get away with weights stuffed in bra. My BMI was 48.8 and was told they wouldn't touch you if you were under 50. So I was stuffing my face (not difficult) with rubbish to up it before my 1st appointment. I was checking every couple of days, and depending on which site you go on it's different so stuck with the nhs one. Got to what I thought was 50.4, but when I got there they measured me an inch shorter than I thought I was, although I couldn't stand up straight because of back problems, and i came in at 52.3, just shows what an inch can do!
