Time to take it back to the library. What I Eat has been a fascinating trip around the world and through the diets of a huge variety of persons. I doubt there is anyone who would not find something of interest - the photos are memorable , from scenery to people to the tent in a valley in Tibet with satellite dish and solar panels.

It does not always appear to be the more active occupation. Is it the difference in types of foods? Do some foods utilize more calories in digestion than others? We know about glycemic index; does it make a huge difference. Is 1000 calories from junk food worse than 1000 calories from cornmeal porridge, eg.?

I have a whole new area to consider. The web site:
