Not a lot new if one has read In Defense of Food, but it's much more "punchy." I hadn't previously been exposed to the "wordoid." Loved it! Other thoughts I will keep:
If you're not hungry enough to eat an apple, then you are not hungry.
You should eat no more food at a meal than would fit into the the bowl formed by your hands when cupped together.
No, a desk is not a table. :-)
