A loss of appetite due to extreme heat. Summer anorexics often will only eat one large meal a day (dinner), only to wake up the next morning and find their stomachs are unusually flat and empty. This seasonal condition begins in late May and lasts until early September, when the stress and pressure of a new school year force the summer anorexic to gain back the weight they lost over the summer (and more).
Laura: Last night, all I had was a triple-cheeseburger with fries and onion rings. When I woke up this morning, my stomach was so flat, but I wasn't hungry! I think I have summer anorexia.
Annai: You probably do. Don't worry, once school starts back up, you'll start eating again.
