Can Robert F. Kennedy Jr. put the country on a diet and Make America Healthy Again? Just asking questions. 

The MAHA Report is a 73-page document put out by a government commission headed by Health and Human Services (HHS) Secretary RFJ Jr. Its goal is to "study the scope of the chronic childhood disease crisis and any potential causes including the American diet." The report points out that childhood obesity rates in the U.S. remain higher than in other G7 countries.



We invited Gary Taubes to join us today because he's a science journalist and researcher who has spent more than two decades studying the American diet. His books include Good Calories, Bad Calories, Why We Get Fat, and The Case Against Sugar. He writes about nutrition science in his Substack, Uncertainty Principles, where he has tackled the question of whether ultra-processed foods are the likely culprit driving America's obesity problem.

We also discuss whether RFK Jr. is more likely to improve or derail U.S. health and nutrition research, the recent resignation of one of the National Institutes of Health's top nutrition researchers, and a challenge to Taubes' "sugar hypothesis" from the pseudonymous blogger Cremieux Recueil.

Zach Weissmueller: Can RFK Jr. put the country on a diet and Make America Healthy Again? Just Asking Questions. The MAHA Report is a 73-page document put out by a government commission headed by Health and Human Services Secretary Robert F. Kennedy Jr., which aims to, quote, 

"Study the scope of the chronic childhood disease crisis and any potential causes, including the American diet." 

The report points out that childhood obesity remains higher in the U.S. versus other G7 countries. And we've invited Gary Taubes to talk about this today because he's a science journalist and a researcher who's written about and studied the American diet for more than two decades with books like Good Calories, Bad Calories, Why We Get Fat, and The Case Against Sugar. He writes about nutrition science at his Substack, Uncertainty Principles. 

Gary, thank you for coming on the show.

Gary Taubes: Thank you for having me, Zach.

Liz Wolfe: However you feel about him, you can't exactly deny that RFK Jr. is a pretty major disrupter to the medical establishment. What has your reaction been so far to what he's done at HHS, but also the broader MAHA agenda?

Gary Taubes: I mean, he is a major disrupter to the medical establishment. I have it fall kind of in the mid-range here in that all my research has been about nutrition and chronic disease, and I think that the medical establishment has made some significant mistakes that have led us to where we are today. And yet I tend to trust them more on other issues like vaccines than I do RFK Jr. and his colleagues. So I can comment on the nutrition. The many other ways in which he's disrupting the major medical establishment probably scare me as much as they scare anyone else.

Zach Weissmueller: So yeah, what is your take then on the nutrition aspect? Before we get into the specifics of this report, just your overview, your early impressions of what they're pursuing.

Gary Taubes: Clearly we have a problem in this country that's nutrition-related, a problem around the world, which are obesity and diabetes epidemics that begin to appear when populations Westernize their diets. So anywhere you look, from the Arctic on down, you'll find populations growing obese and diabetic in association with eating Western diets. And then the question is: What aspect of the diet is to blame? And everybody's got an opinion on that. And I think everybody has an opinion because the science has been so bad for the last century that it hasn't nailed anything down the way you would hope that science would give you unambiguous conclusions.

So we have a problem. RFK Jr. admits we have a problem. The previous administration's approach to this was to push for personalized nutrition—the idea that we could somehow identify in advance what everyone's ideal diet would be.
