When does excercising turn into over excercising?

[Fiction]

Title says it all really.

Assuming you're not an athlete; when it starts to dictate your life.

[Syvelocin]

When you're burning more than you're eating I would say, which is common when eating as little as we do. Even when you're burning less than that, but a big percentage of your caloric intake. 400 calories isn't much, but when you burn it all and that's how much you've eaten, it's not good.

Ok thank you :)
