David and Renee talk to Gary Taubes, an investigative science researcher, about the low-carb diet we all know as “keto” to better understand how it works. David and I agree on very little in life. That’s a topic for another day. But one thing we’re both curious about is the reason for how we feel when we adhere to a relatively low-carb way of eating. While we still take pleasure in eating, we wanted to learn more about the science behind a more modest intake of carbs. So we sought out one of the most knowledgable and controversial authorities on the topic, investigative science journalist Gary Taubes, so he could elucidate us with his understanding of the science of weight loss following years of research. Here’s what he had to say.—Renee Schettler.
