I have always been quite restrictive with food, but it has got worse in the last year or so and I am very fearful of weight gain. I eat very minimally and if I think I have gained any weight at all I will hold back even more. I never ever eat anything that would be considered a treat, and I think about food at all the time. I am just over 50kg and 5 foot 6 so I think that is a BMI of around 18. I'm just about to turn 38 so not young. Thing is I am not really sure what to do about this. I think it's not a low enough weight to be bothering the GP with and they will have much more urgent cases to be dealing with. I do eat something every day. I know there is BEAT but I do not even know where to start in terms of contacting them.
