Dr. Leland Stillman and Amy Arp examine time-restricted eating through a 2012 study where mice on a high-fat diet stayed metabolically healthy eating only 8 hours a day, without cutting calories. They question whether mouse findings translate to humans, since mice naturally avoid high-fat food and aren't carnivores.

Hello everyone, Dr. Stillman and Amy Arp here today. If you did try to catch this live, we apologize, there was a problem with the link. I won't belabor that point, but you'll get the replay anyway. So Amy, what do you have for us today?
Wonderful. So today we're going to talk about time-restricted feeding, or you might have heard it as intermittent fasting. So we will touch on a couple different aspects of this, and then Dr. Stillman will give his opinion at the end. So let me share my screen. There, I think we can see it.
Yep.
Wonderful. So as I was researching this, there are a handful of really renowned researchers that are doing a lot of research currently on time-restricted feeding or intermittent fasting. And so one of them that I picked up was this guy, Dr. Panda. And so I'm going to be presenting some of his, um, research. This article's from 2012, but he also has more current research that he's doing right now. But this research was what he's basing a lot of stuff on in his current research.
He's one of the biggest researchers in this space. You will see him in all of the biohacking, longevity, health and wellness, whatever.
And it's interesting to go through and see what he's found, and then we can discuss, you know, what we think about that. So this article is titled Time-Restricted Feeding Without Reducing Caloric Intake Prevents metabolic diseases in mice fed a high-fat diet. So in this—
go ahead and guess what they found.
Uh, sure.
I mean, they found that when they restrict the time period of eating— I get bored saying the word feeding— yes, they prevent the changes of metabolic syndrome that we see in humans in mice when they eat a high-fat diet. Now what I find The minute I see a study like this, I think, okay, tell me something I don't already know.
Exactly.
This was 2012.
Mm-hmm.
People have known this for a lot longer than 12 years. This is not new information. The other thing is, I don't know if any of you know this, but mice don't eat high-fat diets.
Yes, correct.
Also, even even the fats that they do eat, highly, highly, um, they're not eating a lot of animal fat. For those of you don't know, mice are not carnivores. However, interestingly enough, and most people don't know this, almost all animals are opportunistic when it comes to feeding. So if you— if a deer in the wild stumbles across a ground-nesting bird and there are eggs, the deer may actually chomp down those eggs. Believe it or not, crazy things happen in nature that are not making it into the public consciousness. Throws huge, uh, kinks into some of the arguments for, well, you know, these plant-based creatures are— it's like, these plant-based creatures are healthy because their organs are completely different, because— and they don't— they would eat They would eat other animals if they could get away with it, but they're not designed to, to catch them and hunt them down and kill them. So yeah, I mean, studies like this are a dime a dozen. Was there anything really interesting or unique about this one that you think we need to comment on?
Well, one thing that was interesting is as I was researching, I was trying to understand why they pick this 8-hour feeding window versus like a 9-hour or a 10-hour or something, let's say. And in this specific, um, article,
