Hi. I have a bmi of 27. Ideally I have at least 2 stone to lose. I was thinking of starting weight loss jabs after seeing 2 friends lose weight. I've just seen that the minimum bmi is 30 though. Friend 1 no way has a bmi of over 25! I don't have any medical issues. Is there no way to sign up for this unless I do it back street style like my friend must be (I won't be doing that).
