## Summary

This video critiques FDA Commissioner Dr. Marty Makary's recent statements on saturated fat and heart disease, accusing him of spreading misinformation by selectively citing flawed studies while ignoring the broader body of evidence. The speaker dissects Makary's references, particularly the Minnesota Heart Study, and highlights contradictions between his public remarks and official dietary guidelines.

### Key Points

- **Context and Warning** [00:15] — The video presents a short clip of Dr. Marty Makary discussing saturated fats and heart disease, warning that it exemplifies poor science communication that can harm public health.
- **Misrepresentation of Evidence** [00:58] — Makary claims only three large studies failed to show a link between saturated fat and heart disease. In reality, there are at least 14 randomized controlled trials, and meta-analyses show reduced heart disease risk when saturated fat is moderated.
- **Flawed Citation of Minnesota Study** [01:42] — Makary says the Minnesota trial had a low-fat group with higher heart attacks. But the two groups had 39% vs. 38% fat—identical. The study found no differences in cardiovascular events, deaths, or mortality.
- **Critical Trial Limitations** [02:53] — The Minnesota trial was interrupted early with over 80% participant loss, making it underpowered. Issues with trans fats in the 1960s-70s may have confounded results.
- **Selective Use of Autopsy Data** [03:59] — Makary cites autopsy data from 1.6% of participants showing more heart attacks in the intervention group. However, overall cardiovascular events showed no difference, so this subset may not be representative.
- **Contradiction in Guidelines** [06:02] — Despite claiming saturated fat dogma is flawed, the new dietary guidelines Makary helped write maintain the same 10% calorie limit from saturated fat. This inconsistency is called out as dishonest and reckless.

### Conclusion

The speaker concludes that Makary's rhetoric undermines public trust in nutrition science by cherry-picking evidence and contradicting official guidelines. The video urges viewers to look at the totality of evidence rather than isolated, flawed studies.

## Transcript

The FDA commissioner, Dr. Marty Makary, he heads  the Food and Drug Administration in the United   States. He was appointed by RFK Jr. last year. He  just gave an interview on TV where he talks about   saturated fats and heart disease. We're going to  take a look. It's a very short video. I think it's  
a great example of how not to communicate science  to the public. And guys, we're going to try to   stick to the facts. I ask that you help out. We're  not going to politicize this. It's incredibly   dangerous to politicize science. Facts are facts  regardless of which political party we like. Well,  
sure we want to promote healthy fats, but you  know, we were encouraging as a medical field   people for decades to eat egg white, you know,  egg white only eggs. And if you think about that  
recommendation, it was really based on the flawed  medical dogma of Dr. Ancel Keys in the 1960s and   it became medical group think. Three large  studies, gigantic studies, including two of  
the largest databased uh uh studies in the history  of medicine tried to prove the association between   saturated fat intake and heart disease. And all  three failed to show that. Okay, we have dozens  
of studies on saturated fat and heart disease,  not three. And even if we just look at randomized   controlled trials on this question, there's at  least 14 of those, not three. And when we put the   evidence together, what we call a meta-analysis,  and we do that rigorously, we see a lower risk of  
heart disease events like heart attacks or strokes  when saturated fat is moderated. So that's the big   picture in this field. He doesn't mention any of  that. He wants to focus on specific studies. Okay,  
let's see. Including the famous Minnesota heart  study that showed those who had the low-fat diet   in the randomized trial had higher rates of  heart attacks. Okay, there was no low-fat   group in Minnesota. One group was 39% fat. The  other was 38% fat. Identical. There's no low-fat  
group. This isn't some footnote. This is on  top of the first page of the study. It's the   summary of the paper. So, he's on TV bringing  up a study that he's not familiar with. Maybe   he's never read it because the whole point of  the study is to test diets. He doesn't know  
what diets they tested. Okay. He also said they  had higher rates of heart attacks. Same place,   top of the first page. They found no differences  in cardiovascular events, cardiovascular deaths,   or total mortality. Now, it's important to  understand this trial, the Minnesota trial,  
was interrupted abruptly, long before it was  scheduled to end. So, they planned to run it   for 3 to four years because it takes a while for  things like heart attacks or deaths to develop and  
accrue. It doesn't happen overnight. But they lost  almost all of their participants, more than 80% of   participants were lost. 75% lost in the first  year alone. So the trial was aborted and even  
during that short follow-up, the participants were  in and out of the trial. During that period, they   were on and off the diets. So it's not surprising  that they didn't find a significant difference   between the groups. It's totally expected. And  there's more issues with this trial. For example,  
there's a question with trans fats. This trial  took place in the 60s and 70s. A number of foods   had industrial trans fats, margarine, and other  processed foods. At the time, this wasn't well   understood. So, it's very possible that one of  the groups was eating more trans fats than the  
other. Nobody knows for sure because there's no  quantification. Now, much later in the 2010s,   they published some additional data from notebooks  and from a thesis, including some autopsy reports  
for a small subset of participants, about 1 to  2% of the total folks in the trial. Trial started   out with more than 9,000 people. Most of those  didn't die during the trial. Of those who died,  
about 500 deaths. We don't have autopsy reports  for most. So, they got autopsy reports, they   recovered them for about 1.6% of the participants  in the trial. And what they found was in the  
intervention group, 31 participants had at least  one heart attack detected in the autopsy. So,   this could have been a silent heart attack. And in  the control group it was 16 individuals. And these  
folks for whom they recovered the autopsy data,  they had been in the trial for less than a year by   the time they died. So, interesting observation.  But is this even representative of the total  
sample? Because they didn't see a difference in  cardiovascular events like heart attacks overall   when they looked at all the participants not just  this tiny sample. Was this caused by the oils they   were given in the trial? Was it caused by trans  fats in the trial? Was it even caused by foods  
from the trial? Because they've been in the trial  for less than a year. Maybe it's a fluke. Maybe   these heart attacks happened before the trial  started. Nobody knows for sure. My point is,  
you handpick one trial with massive issues. You  ignore the majority of the evidence in this field,   that goes in the opposite direction. Even within  this trial, you handpick one observation in a tiny  
percentage of participants. You ignore most of  what the trial reported. You ignore that overall   there was no difference in cardiovascular events.  And based on this, you go on this rant that all  
scientists are wrong. It's all dogma and group  think. My opinion, this is a perfect example of   how not to communicate science. This confuses the  public and this harms people. And that's because  
when you eradicate fat, you replace it with  refined carbohydrates, which increase general   body inflammation. You don't have to. You can  eat unprocessed carbohydrates, but also nobody's  
saying that you have to eradicate fats. Nobody  in professional nutrition nowadays is saying that   you have to eat a low-fat diet. We moved past that  many years ago, decades ago. These guys are stuck   in the past. This whole endeavor is a straw man  argument, right? It's like the fixation with the  
pyramid. The pyramid was discontinued 15 years  ago. They're still going on and on about the   pyramid, the pyramid. Healthy fats are recommended  almost universally by professionals in nutrition   and they've been recommended for many years.  Extra virgin olive oil, fatty fish, seafood,  
nuts and seeds, avocados. And the main irony  with this is this whole narrative of saturated   fat is misunderstood, was unfairly demonized,  they don't even believe that. They just put  
out national dietary guidelines that they wrote  where they uphold the same limit we've always had,   under 10% of calories from saturated fat. Here  he is in the press conference just last week  
announcing the guidelines. How much saturated fats  Americans should be consuming. I'm going to let   Marty take that since he wrote a book. Look, the  old the old dogma the 1960s when Eisenhower had  
his heart attack and Anel Keys said it was the  saturated fat that's never been substantiated   and so that flawed research has become dogma  over the years and eventually the conversation   was sidelined. In this new guide guidance  we are telling young people, kids, schools,  
you don't need to tiptoe around fat and dairy.  You don't need to push low-fat um uh milk to   kids. And we are maintaining the 10% of calories  as saturated fat in the guidance. Does that make  
any sense to you? It's all flawed research.  It's all dogma. It's never been substantiated,   but we're upholding the same limit on saturated  fat we've always had. What? If you believe that   that gap is not based on good science, then why  are you recommending it to 300 million people?  
Just because the guys before did? Just because  every country on the planet does? Isn't that   the definition of dogma and groupthink and being a  sheep? Exactly the thing they like to accuse other  
people of doing? And if the science does support  that cap, as you said in your official document,   why are you telling people otherwise in  a press conference? Completely reckless,   right? Completely irresponsible, sending people  to an early grave. The truth is this narrative is  
very popular. People want to hear that butter  is fine or even good for you. All scientists   are wrong. It's unfairly demonized. It's a very  popular rhetoric. But in an official document,  
there's a lot more accountability. So there they  don't play these games. They go with the balance   of evidence and what most scientists are telling  them is a good idea, right? So in the future if   there's a lawsuit they can say "well we, we said  under 10% in the document", right? While at the  
same time dog-whistling to the public that it's  all dogma, don't worry about it, just eat all   the butter you want. Do you see how dishonest  that is, to say one thing and do another in an   official document? This is how politicians behave.  It's got nothing to do with science or facts. If  
you find this topic of saturated fat confusing,  we have a video covering all of the evidence and   practical takeaways. So, I'll link that right  here. Check it out. I'll see you in there.
