Okay, so we'll get into all that. But let me first tell you the background on some of this. So stemming from those Ultraman studies and our sleep was sort of linked into this. So if anyone can remember, those old shows were giant weight loss shows on television that existed for a long time, the Ultraman. The TV talking heads would always say, stop it. There's a cutoff time. There's a cutoff time.

And I remember being a grad student at the time or even undergrad at the time and thinking, well, everybody I know eats at night and they're all very much fit and in shape and have no problem. And so this dichotomy is going on. I'm thinking, I don't know. I've never seen a paper on it. I'd love to see that and started looking at it a little bit here and there.

And then finally, you know, when I was independent investigator, was it? started on that path.

First one in my own lab at Florida State. We got some small funding for it, and we decided, let's see what happens. And then 15 years later, we're designing two new ones right now. Okay. Let me take you on that story. Please. Yeah. So that was going on. People were saying, don't eat at this time. Don't eat. I'm thinking, I don't know. I know a lot of people.

Plus, in the bodybuilding circle, the figure world, people would purposefully eat at night, or they would purposely, if they had to wake up to use the bathroom, they'd have a protein shake sitting right there in the bathroom.

It was super common. So there was just these different worlds. And so clearly, they were like, we've got to start somewhere. What's happening here? So we started looking through the literature. And this was about 2010. And there was really nothing that existed in the way that we are thinking about pre-sleep feeding and what to eat before bed.

There was some data in large mixed meals like having your full-on dinner before bed late at night that weren't very good. So 1993, Roman did a study where – I remember they gave 544 calories and they gave you this in the morning, in the afternoon or in the evening. And they just measured your metabolic response to the meal. And it was just a stair step.

And they just measured your metabolic response to the meal. And it was just a stair step.

So if you had it in the morning, you had the best response. In the middle of the day, you had a medium response. If you had it at night, you had a very low metabolic response to that meal.

Exactly. Yeah. More to the story, but... And in reverse, they'd say, if you had your calories at night, you're going to get fat. Bingo. You're going to gain weight.

And then several other things have happened along the way. There was a study in 2004 from DeCastro, and that looked at like, when do you feel the hungriest and when do you eat the biggest meal? And they're always in the evening. And so all the data were lining up that your hungriest at that time, your ability to like control your caloric intake. It's worse at that time.
