Lessons in eating

I have eaten over an hour and a half ago.  I realize that I have eaten too much at one time.  It is as if I need a lesson in eating in moderation.  I admit that I do love to eat, but I have to realize that food does not love me back.  At breakfast, I ate only Greek yogurt, and only yogurt.  I wonder if I should have eaten fruit along with it or if I did well enough.  Lunch is pretty much a free for all meal and so is dinner, where I tend to eat the same thing that I eat at lunchtime.  It happens at times, but it didn't happen today.  Today is a lesson that I would like to learn for tomorrow.
