I'm with amdevelish re eating lc sf treats when you get cravings. However, if you keep reminding yourself that as long as you expend more energy daily than the food you consume you will lose weight. It might be very slow in coming off but if you try hard to keep exercising and push yourself on those days you feel more energetic you'll see the weight come off faster.

Don't give up on lc'ing or the weight and the low blood sugar problems will resume. then you'll have to deal with the possibility of diabetes in the future. Stick to lc sf options and try increase the exercise - you know it'll work!
