When talking about portion sizes in the standard American diet, it's really frightening to see those huge plates in restaurants and in home kitchens. Where did all this food come from (for a single meal, anyway)?

Those larger portions are causing many of us to overeat, and endocrine disruptors like MSG (and similar glutamic acid variants like yeast extract) make us continue eating way beyond when out body is full. In other words, more food sales at the expense of more obesity. Not good.

The way to break the overeating cycle would be to avoid MSG and yeast extract in your foods (which takes a large effort, trust me) or write down that you'll only eat so much -- then stop eating once that goal is reached (no matter how much food is left).
