What do you think of this theory that CO2 makes people fat?
The study (published in Nature) says that CO2 is making us fat by affecting neurons called orexins that are involved in metabolism and food intake because of the decrease in our blood's pH (more acidic blood makes us want to eat more?). They put men in a chamber with increasing CO2 levels and found that men who were exposed to more CO2 ate 6% more than the other men and also found they had faster heart rates (they also saw the same results in dogs, cat and mice). So this whole acidic blood pH thing leads to eating healthier (fruits and veggies lower pH) and like, possibly living in the mountains 'cause we expel more CO2 up there.
It's certainly interesting to think about. Do you consider this to be a legitimate hypothesis about the obesity epidemic?
