why calories don't matter

Caloric science is inherently flawed for 5 reasons (at least)

1. it assumes 100% absorption (doesn't count excretion)
   
2. it assumes that the amount of energy released by combustion is the same as released by enzymatic breakdown
3. people in china eat more calories and have less obesity
4. calories from different sources are absorbed differently
5. correlations don't show causation. People who are heavy eat more calories. Did the calories make them fat, or do they need more calories because they are fat? Perhaps they are both symptoms of a deeper problem.

I will go into this deeper at a later time, but it is all explained in my book: The Asian Diet: Simple secrets for eating right, losing weight, and being well. http://www.theasiandiet.com
