Do you consider 175 pounds and 6 feet overweight?

Well BMI is normal but it's mostly up to you if you feel well with that weight then you're alright.

I don't get full either, just calculate how much you eat for a few days and mark the times you get uncomfortable after eating.

By this way, You should be able to find your limit easily , just make sure to don't cross your limits.

Also certain foods would make you more uncomfortable then others , careful about those as well.
