I think this is my biggest problem. Yesterday I made spaguetti squash. I went to Fitday to check the nutrition facts. I thought one cup was not going to be enough. Today, I had 1/2 a cup, I ate it slowly and it was plenty. It reminds me of what Ladybelle said about taking the time to realize you're full. I'm so used to not measuring and filling a plate without thinking, and to finish what I have in front of me without stopping to think if I'm full. But by measuring and cutting, during the last two days I only had 1400 calories, vs. the 2,000 I was eating before. (Although I know if I eat something sweet, portion control is almost impossible!)
Yvonne, I am going to take your suggestion and start fixing my meals on a smaller (dessert?) plate.
