Weight / Fat loss

If you have been eating less calories than expended for 6 months, no amount of overtraining/starvation mode would have held out this long.

Are you keeping a food diary and being completely honest in it, or as you are already doing then see a doctor.

Yep - some days (generally weekends) I'm over but not by ridic amounts and if you take it as energy expended Vs eating over 7 days, I'm under the weekly amount.

I should say I did initially lose a stone over about 3 or 4 months when I started stepping up the exercise at the beginning of the year but the weight loss since April/May has kinda stalled : /
