Compulsive eating is only the symptom.
The rest of her tweet is a little touchy-feely for my taste. But I like this first part. For me, compulsive eating is a learned coping mechanism. The urge to overeat means that something, whether it is nutrition, physical activity, sleep, and/or stress management, is off balance.
So I use the urge to overeat as my own personal barometer and adjust accordingly!
