I'm also finding that it feels sad sometimes to stop when I reach fullness. The other day I had made homemade waffles for breakfast and topped them with some stewed peaches. It was such a delicious breakfast, but I felt full after about 10 bites. I was disappointed because I was going to be in meetings all day and knew that when I was hungry again, there wouldn't be anything as good available. I stopped anyway, but I felt frustrated.
Because I'm not dieting, I don't feel the need to finish everything. If I want, I can use DietSnaps to record how much I left on my plate, but I usually don't bother. I also find that the portion sizes that I learned so well from Weight Watchers and calorie counting are often too big if I'm having several items. In that way, dieting might have actually made me eat more at times, because if I was counting it, I was sure going eat it.
I also realize that since I had the summer off and didn't have my French lessons or my art classes over the summer, it's not surprising that I was bored and using food for entertainment. Having the summer off feels like a luxury, but it's expensive to live a life of leisure -- almost everything we do costs money, so we were either spending too much to entertain ourselves or spending a lot of time doing very little. It was so beastly hot that outdoor exercise wasn't as much fun as it usually is. I'm enjoying the cooler weather now.
