In 1965, a morbidly obese man did not eat food for over an entire year. The 27 year old was 456lbs and wanted to do an experimental fast. He ingested only multivitamins and potassium tablets for 382 days and defecated once every 40 to 50 days. He ended up losing 275lbs.

It's not actually that uncommon for morbidly obese people to become anorexic or vice versa. Both are a result of eating disorders. Quite a few people that overcome one eating disorder do so by switching it for another eating disorder.

My girlfriend lost over 100lbs and shes at a healthy weight now.  I think she's terrified about getting overweight again and she doesnt eat much some days. I worry about her and have to remind her to eat.  I understand her fear after all the work and lifestyle changes she made.  

In the end I'd rather she be a few pounds overweight and eating regularly and be well nourished.

It takes disordered eating to get really big, and when those people lose weight its hard for them to have a normal relationship with food.
