Heart attacks are the number one killer in america. Fat has nine calories per gram, and protein has four calories per gram. The idea that losing weight requires you to eat fewer calories, therefore eat less fat is not backed up by science. People in the 18 hundreds in America ate literally the same amount of meat as Americans in the 19 fifties. Amer have always had a really high fat diet. And there's another way of thinking about this that is sort of like icares, right? We flew too close to the sun. We tried tomage, and now we have lot. Righta feels bazarre for, like, a conversation that is ostensibly about science.
