If you don't mind me asking, what made you choose 1600 as your calories per day? If you don't mind, how tall are you, how much do you weigh, what is your activity level and are you trying to lose or maintain?
(If this is too personal, ignore it, but I thought I might be able to help...)
Have you thought about trying to include more protein in your diet? These last few days, after a regrettable experience with a piece of key lime pie on Friday night, I've been eating nothing but safe foods, which means virtually no protein. As a result, I've been ravenous and have eaten more cals than I really should. I think my normal levels of protein keep me full.
all those years it wasn't IBS - it was celiac!
