Why did I suddenly lose the desire to eat?

I went through the exact same thing! Infact until this day, I still do! I'll eat like a pig for months, and then BAM- for 2 weeks I'll have ZERO appetite. It's really weird. I know theres nothing wrong with me,and everything is perfectly ok. I just think women have all different types of bodies. Trust me, it will come back within a few weeks. And if it doesn't, talk to your doctor and see what he says. Good luck hun! :)

People are very different. Loss of interest in normal activities can be a sign of depression but more likely it's just "your way". My brother-in-law only eats once a day(in the evenings), has been doing this for years and has no unusual health problems (except his hair style LOL).

I wish I had that problem. I would eat all day if I knew I wouldn't gain 100 pounds!! Have you been under a lot of stress lately. That could be a reason.
