i don't eat full meals - i eat snack sized portions. i used to do that when i was a bodybuilder because you don't want to let your blood sugar drop or spike and you want some protein in your system all the time. now i'm diabetic and again eating small portions 5 to 6 times per day not only helps me lose weight but keeps my blood sugar from spiking.

and of course, it's a lot easier to grab a pre-measured single portion of something than to cook several things and plate them, then go to the table. this way, i can eat as i work.
