Hi. I used to be a bmi of about 18 naturally, then I got anorexia. In an attempt to recover I ended up following a recovery plan of 3-4000 calories online. Now I don't own a scale but I know I'm a bmi of 35-40 from a previous hospital weigh-in. I would really like to lose weight but I need to lose nearly EDIT: I meant 7-8st (I'm 5ft 11 female). The NHS calculator says to eat about 2000 calories though and I have just cut down to 1200 this week but am worried that isn't enough and I don't know if my metabolism ever recovered from my eating disorder? Feeling discouraged that I won't be able to lose it. Also I have lupus so find a lot of activity hard. Any advice?
