Something I don't understand about the problem is rice is junk food, empty calories, but at least some of the stuff people traditionally eat with rice is really good for you. So I kind of limit my carb intake while dumping more good stuff on the plate. So I'm not seeing the problem with portion control or limiting rice intake as an inherent problem. I'll put barely enough rice down to soak up the juice and dump healthy stuff on top like steamed broccoli or grilled shrimps or steamed fish pieces or grilled chicken breast or whatever.
I'm sitting here trying to think of recipes other than blindingly obvious (like fried rice) that must contain heaping piles of rice and can't simply just have more "good stuff" piled on the rice.
Its the same way with unhealthy flavored sauces. I know general tso sauce is nearly pure corn syrup and therefore is bad for me so I use the stuff like people use hot sauce, a taste is enough, a couple drops on each bite and I'm smiling. There's no reason I have to dump the entire bottle of sauce on a couple pieces of grilled chicken.
Given that the "good stuff" tastes better than the rice itself I'm not seeing an appetite or self control problem? Go ahead torture me with extra homemade lemon pepper steamed fish and less of bland tasteless blah rice?
