This conversation with Nick Norwitz was released before the release of a new keto diet study co-authored by today's guest, Dr. Nick Norwitz. Now, this study sparked a lot of interest and a lot of debate online. It was pretty interesting to see the amount of blowback it got
And now, while this new study isn't discussed in the episode, the study that I'm talking about now, the conversation gets into some of these topics and offers valuable context on what led Nick to explore this topic in the first place, including his own health struggles, and now a viral experiment where he lowered his LDL cholesterol by eating a whole sleeve of Oreos a day. It was very fascinating.
He's a character. Welcome to the Dr. Hyman Show. This is Dr. Hyman, and this is a place for conversations that matter. And today, if you're confused about nutrition,
I can't promise you won't be confused in the end, but at least you'll be more educated because we're talking to a MD, almost MD, from Harvard, an Oxford PhD, who's made it his job to understand the science beneath nutrition and metabolic health. His name is Nick Norwitz. He's a graduate valedictorian from Dartmouth. He majored in cell biology and biochemistry. He went to
Oxford to get his PhD in metabolism and study ketones and Parkinson's. He is an enthusiastic person, to say the least. He's very passionate about understanding the underlying mechanism behind our chronic disease epidemic and our metabolic health. He's personally suffered from severe inflammatory bowel disease and cured himself of it through food, which I think is important to take note of.
He's making a name for himself online, and he is also making a name for himself through the academic work on various diets and approaches through scientific literature, including ketogenic diets, cholesterol, lipids, LDL. And he's a great scientific communicator with all kinds of expertise across a array of things that I don't even think I understand. His mantras stay curious.
He loves hard questions. And we went through a lot of hard questions today. We talked about all kinds of things from whether artificial sweeteners are good or bad for you to what does LDL... do in terms of your body's risk for heart disease. And it is at the Boogeyman we thought it was. We talked about carnivore diets, vegan diets, and lots more.
