Sure, sure.
As you were saying that, I was in my head going, okay, okay, okay. So many problems. I got the comments section. I got you guys.

I visited his lab a couple of times a long time ago, but a ton of great work over the years.

Walk us through what that is really quickly. Yeah. It's exactly what it sounds like, but โ

Right. So what you're doing is you're putting a small needle in somebody's belly fat so you can measure exactly how much fat is being burned. The other way to do it is you collect the gases that they're breathing out of their mouth.

Really quickly, What does glycerol have to do with fat?

Right. So what you're able to look at is directly from the tissue, whereas if you're on a metabolic cart and measuring gases, it still sounds and feels like you're measuring fat burning. But as you said earlier, you're not. One is measuring the entire body.

and how much actual carbon dioxide you're breathing out and what you're measuring directly is how much and if you're not familiar with this is lipolysis this is the breakdown of fat and you mentioned this quickly but really making sure folks don't miss it fat burning And fat loss and fat oxidation are not necessarily the same thing. They sound similar.

They sound similar.
This is where we can get lost in science a little bit. But it's really important if you're going to make a claim about what happens to somebody's fat burning with, in your case, what you eat before bed. measuring directly in the tissue itself is going to give you a significantly different answer than measuring a resting metabolic rate or on a car or something like that.

So to tie that together, if the 1993 paper held true and โ the follow-up paper held true and eating before bed was going to make you fatter. What you should have saw in your study is you should have saw the rate of lipolysis go down. You should have seen less fat burning. We're going to refer to it like that.
