I decided not to choose a goal weight as such. I lost alot of weight when I was 17 (I will try to find a photo) and wore a dress (labelled a size 14, it was definitely lying) to the sixth form ball. Said dress is still in my wardrobe so thats my goal, fitting back into that, because I know that weight probably wasnt the only reason i was happy but I was happy with my weight at that point. Weighed something between 10 and 11 stone, not sure what exactly, probably somewhere slap bang between.
The suggested goal of 150 is 10st 10 so its more of a guide for what would be healthy and we'll see when I get there.
