the calorie war thread intrigues me. it has been proven the base metabolic rate calculated by sites such as fitday, is probably pretty close to a persons true bmr.

problem is, i have been fighting with my body to barely palate more than 900 calories, though i supposedly have a bmr around 1700 calories. i have been eating this way for months now.

my question is, am i doing permanent damage to my body, and if so what are the consequences? or will eating 1700 calories per day fix me up without a hitch?

thanks
