An engineer and doctor traces how our food changed. Hunter-gatherers ate to fullness and stayed lean. Agriculture 10,000 years ago diluted protein with carbs. Industrial processing refined sugars and oils into products our bodies don't recognize, leaving us eating the same volume but gaining weight.
What did you discover in all of this study as to why you think we're so overfat? So I, you know, I got an engineering degree before I went to medical school, and so I'm really into reverse engineering things. And I figured, okay, the only way to figure out what to do to fix all this stuff is to reverse engineer it and figure out how it occurred to begin with. So in both books, I go all the way back to the very beginning. I zoom out as much as you can, like, what is eating? Exactly what are the nutrients we're eating, how do they get there, where do they come from, and then what happens over time with the food supply to basically change it to the point that we all just eat to satiety like we've always done for, you know, 1.5 million years, except now we're all morbidly obese when we used to have perfect body composition. And so I basically break it all down. I started at the very, very beginning. It's really basics, like what is eating, you know. It's like, right, this is where all of the macros actually come from and get there. And then we about, you know, basically what happened with, you know, first of all, agriculture, you know, 10,000 years ago. This is how we basically upped the yield of carbs and fats, and this is how we got, you know, protein dilution. And then we had the Industrial Revolution and the bulk refining and processing of, you know, refined carbs and fats and sugar and flour and oil, and boom, now everybody's overweight.
