On the causes of Obesity:
"The first is the natural temperament of the individual (....) The second principal cause lies in the starches and flours which man uses as the base for his daily nourishment....A double cause of obseity reults from too much sleep with little exercise....The final cause of obesity is excess, whether in eating or drinking"
Brillant-Savarin JA (1826)--The Physiology of Taste, or Meditations on Transcendental gastronomy---
this was writen in 1826, almost 200 hundreds of years ago. An it is so simple... EAT LESS MOVE MORE...
But we want to complicate things and lookf or hidden causes of obesity (like genetics...???) or some strange carb to protein ratio or the illusive glicemic index.
Look guys and gals in 1826 people alredy knew (an they were no scientists at all).
Why don't we go to simplicity????
