But, you know, they're not like at this conference. We eat at like 7 o'clock and there's always dessert. You're hanging around, you're networking, you're having a friendly conversation. And so, yeah, I'll have a bite or two or some cake or a cookie or something that's around. Does it affect my sleep?
No, because I know I'm not going to get this spike in blood sugar because my insulin is very sensitive. My body can mobilize that and then bring it into the cell and I don't get the hyperglycemic response. And I certainly don't get an increase in heart rate. But everybody's different. So what I tell people is get your continuous glucose monitor and then figure out what you eat.
Again, take a food diary and figure out how big did that lead to an increase in blood glucose and how long did that persist. And then you have to experiment with yourself. And if you're concerned about the health is our number one asset. And if you're concerned about that, don't take my word because what I do may not work for you. You may not have the discipline to do what I do. Yeah.
Somebody else does that, you know, like the Ben Greenfields and the Dave Asprey support. I don't do what they do. It works for them, but it doesn't work for me.
Now, look, it's improving your metabolic flexibility and improving insulin sensitivity. Because people monitor fasting glucose levels. And glucose is bad because it sticks to proteins and renders things dysfunctional. But the inflammation that occurs from that is due to the hyperinsulinemia, the elevation of insulin for prolonged periods of time.
And so if you can improve insulin sensitivity, and that's where muscle mass comes in, because there's three main kind of cell types that take up glucose and are insulin sensitive. It's skeletal muscle, it's the liver cells, and it's the fat tissue. So if you increase in your skeletal muscle, then you're increasing insulin sensitivity, increasing glucose uptake.
And people who don't have a lot of muscle mass, then they're relying on the liver. It overburdens the liver, the fat cells, the adipose cells. And so you're working at 67% instead of 100%.
Yeah, the chronic hyperglycemia. And you monitor this through hemoglobin A1C. And what is that? That's sugar that's stuck to hemoglobin, the blood cell that carries oxygen to all cells in the body. But it's not unique to hemoglobin. It sticks to other proteins. It sticks to enzymes like nitric oxide synthase.
And in enzymology, these proteins have to be flexible and nimble and undergo conformational change to transfer electrons. If you got too much sugar and the sugar stuck to it, it's kind of, it's glue, right? If you spill a soda on the countertop and you come back the next day, what is it? It's sticky. That's glue. It's glucose. It's sugar. Sucrose in that case.
So it does the same thing in the body. Everything sticks together and then you can't, you know, red blood cells can't form. You can't deliver oxygen. develop, you know, coach your neurons, you develop neuropathy. It's just bad news. You have to eliminate sugar.
Certainly at the bottom, it's probably not as bad as smoking or seed oils, but it's certainly not good. I mean, again, it's risk benefit. Are there nutrients in that? There's probably not a lot of healthy protein, probably not a healthy fats. There's a lot of carbs. It's going to disrupt your sleep. It's going to disrupt your sleep. So what do you think, a D?
Yeah, probably an E, yeah, D. Okay, great. We'll put that as a D.
I don't eat breakfast, but I know people who do. If you're going to eat breakfast, a high-protein, quality-fat breakfast is the best. The worst thing you can do for breakfast is eat pancakes and drink milk and things like that. Bacon, it's high-quality protein. It's good fat. And so if you're going to break your fast, then bacon is the way to go. Okay, you like bacon. I like bacon.
No, but it's probably not promoting nitric oxide. So separate from nitric oxide. Okay. Yeah, bacon for breakfast. I think an intermittent fast every day and not breaking your fast in the morning is kind of the best prescription. But if you're going to eat breakfast, bacon for breakfast would probably be a B. Okay, great.
Me too. That's my preference.
No, I agree. But not a high carb breakfast. If you, if you have good metabolic flexibility, the body is designed to maintain optimal blood sugar. We need glucose. We need sugar to fuel cells, especially in the brain. That's a primary energy source for the brain is glucose. If you fast, the body then starts to break down glycogen stores primarily in the muscle and mobilize that as glucose.
So even if you're not consuming it, your body is making it through glycolysis and the breakdown of glycogen. So that's how our body maintains homeostasis.
But if you're not and you don't have a lot of glycogen stores, which a lot of people don't, you can do that through some impedance and figure out then you're going to get some low blood sugar and maybe feel lightheaded and dizziness and develop a little syncope and feel bad. Then I would recommend you probably have to eat. But again, it's the individual. It's the personalization.
Of medicine and nutrition.
Well, I think it's probably one of the worst things you can do. And again, it's not based on opinion. It's based on data, both clinical observational data and then understanding the mechanism of what that does. And so I, you know, I kind of compare it to the chronic use of antibiotics. No matter what physician you go to, here in the U.S.
