If you're used to 800, 500 is a pretty huge drop. My intake to maintain weight is about 2600kcal/day as a lightly-moderately active person. I normally do a breakfast of about 400-500 calories, and then 900-1000 for lunch and dinner. So if I weren't just waking up, 500-600 would be very small for me.
