I asked Matt the other day why there are fat people like Honey Boo Boo type families. They don’t seem to ever starve themselves. He said that people are born with certain genetic issues and they also probably eat lots of PUFAs which suppresses the metabolism. It’s true that they eat lots of packaged foods like potato chips that are fried in vegetable oil etc.
I wish there was more proof of this! It seems scary to go in the direction of an endless weight gain.
