I have observed before that a little meat goes a long way with my two type As. For years I was embarrassed that I took bigger helpings of meat than my husband. I was still hungry if I ate the amount that he ate. My daughter eats what I would consider a child's portion of meat, though she is in high school.

Recently I've been noticing that among meats, some fill me up faster than others. I am satisfied with a normal serving of beef and lamb. Four or five ounces is fine. It takes a little more chicken or turkey to get the same feeling of well being. I eat nearly twice what is considered a normal serving of fish.

A six ounce can of tuna, for instance, is supposed to contain two servings. My daughter thinks half a can of tuna is just right. I need a whole can. If all I have is a half a can, I add another protein source - like nuts or a neutral cheese)

I'm thinking about this tonight because I fixed cod for dinner. In the midst of the preparation process we had a crisis. (OK if you must know a cell phone was dropped in the swimming pool) I was still pretty wired when we served dinner. I got one piece of cod, and knew it wasn't going to be enough. I ate a piece and a half and felt much better.
