When I was losing weight a few years ago I went down from 14 and a half stone to under 13 in the space of 4 weeks. However I then seemed to stick for ages round about the 11 stone mark - my target weight was 8 stone. However o can say that 11 stone felt infinitely different from being in the 14s although I was definitely overweight at this weight.
Anyway shout out and much love to anyone and everyone on a weight loss programme - it's bloody hard !
