I'm sure you already know this, but your weight loss is likely to slow down quite a bit. Not only will your body get more efficient, but you'll lose less weight the closer you get to a weight that could sustain a 1400 calorie a day diet.
That said, please keep posting your progress. Fucking awesome!@
Yeah there is also some research that says once I reach my maintenance weight, I'll still have to eat less calories than someone who has always been a normal weight, basically my metabolism is permanent fucked.
