@Klaus said in A podcast on Obesity.:
Has anyone actually listened to the podcast or are we going to discuss this based on the title only?
Not the whole thing, but parts of it.
The real tl;dr version is "We don't know what the hell is going on,"
They say that losing weight is (relatively) easy, and keeping it off is (really) hard, but we knew that.
There are so many theories, so many models. You can't blame it all, they say, on genetics, because, as a species, we have pretty much the same genes we had 100 years ago.
Others, like Jason Fung (Insulin resistance theory proponent) attribute it to diet, almost exclusively, pointing to the rise of obesity in China where a rice-heavy diet for centuries didn't lead to obesity. Now, it's endemic in China.
“Asians tend to eat rice, whereas Western societies tend to take their carbohydrate as refined wheat and corn products. It is also possible that changes in Western obesity rates are related to changes in the variety of wheat we are eating.”
