He says 15% protein, but doesn't give a percentage for fat and carbs. I can't imagine they advocate high fat, so again we have a plan that calls for the vast majority of calories to be from carbs. Exactly what caused the obesity problem we see today.

Also, this is still based on calories in and calories out. He says if "Mary" ate a chocolate bar (290 calories) every day, in 2 years she'll put on 26 pounds. But the math is wrong, or they're using some different calculation. 290 multiplied by 730 (number of days in 2 years) is 211,700. If 3500 calories equals 1 pound, you would divide 211,700 by 3500 and come up with 60.48. Why just 26 pounds? Why not 60 pounds?

We all know our bodies are not machines, and CICO doesn't work.

And why model our eating on an orangutan? They're primarily vegetarians, but when fruit becomes scarce, they have been known to hunt for meat (slow lorises, according to an article I read).

Call me skeptical on this one.
