Could Air Pollution Be Making Us Fat?
A new hypothesis proposes that rising levels of CO2 in the atmosphere may be contributing to the obesity epidemic.
The idea proposes that breathing in extra CO2 makes blood more acidic, which in turn causes neurons that regulate appetite, sleep and metabolism to fire more frequently. As a result, we might be eating more, sleeping less and gaining more weight, partly as a result of the air we breathe.
Could diets high in modified sugar substitutes that we can’t easily process be making us fat?
