Pretty neat research on over eating, weight gain with food variety, portions, etc.

Pretty neat little study discussing variety of foods, portion size,
etc., on overeating. Sure makes sense to me! The greater the variety
of foods, the greater the likelihood to overeat. True for animals
(short-term animal studies show about 25% increase in calories) and
also in a group of younger men (not true for a group of older men who
may have been consciously limiting their food intake).

Also snacking, restaurant eating, liquid calories are discussed.

This is one of the reasons I don't want to try a variety of new foods
-- I will find many I want to eat more of than I should.

Yours,
