wow, you are really lucky or maybe have a health issue? but my guess is that if you had a health issue, you would be experiencing some kind of negative side effects which u are not.
personally i think if u can eat that much and don't have a health risk, then go ahead. however, i'd still be careful when choosing foods (not too fatty, sodium, etc).
if you want to curb your apetite anyway, drink a lot of water, eat more whole foods (unprocessed), stay away from white flour products, eat protein. protein does a lot for apetite control.
i have a huge apetite too, for a female
