I dont know if you know this but when a doctor calculates your healthy BMI he doesnt just go by your weight and height.
When I saw mine last year he inputed loads of information, i couldnt see what but i wonder if they add in illnesses, how you look to the eye to some extent, and i know they use age.
This gives a more realistic ideal BMI for you.
We get swept away with the height/weight thing as do the likes of weight watchers i have to say -(even though i told my ww leader what my doctor said she had to go 9lbs under it!!!)
Yeh health HAS to be the number one factor in this - it's no good aiming for a weight that is going to make you unhealthy, one you find too hard to maintain, and one to fit a bog standard chart - and if your doctor is telling you something,I'd say listen to them.
apparantly by my doctor it was okay to be 13stone and not go below 12stone as it woud make me unhealthy to be so low (HAHA) who am I to argue?
So yeh, good docotrs visit you had Barb, and it osunds like you have one with a sensible head on her shoulders, as you do get some who are repelled if you are so much as half a stone overweight!
