Dr. Casey Means: Transform Your Health by Improving Metabolism, Hormone & Blood Sugar Regulation

But this is just one more that I think is fascinating because this was a paper in Nature from โ€“

last year that talked about, and this may actually be one of the most valuable things to people, which is that, again, talking about cravings, we all want to get off the craving grip.

This paper in Nature showed that essentially when people spike their glucose with high-carb, high-starchy foods,

they'll often have a big crash afterwards.

Huberman Lab
Dr. Casey Means: Transform Your Health by Improving Metabolism, Hormone & Blood Sugar Regulation

And the reason for that is because a big spike leads to a lot of insulin secretion and then you soak up all the glucose and sometimes you can actually go below your baseline.

So a small spike usually won't lead to a crash, but a big spike often will.

Huberman Lab

That's called reactive hypoglycemia, postprandial hypoglycemia.

A lot of people think they're dealing with hypoglycemia when in fact what they're really dealing with is that they're spiking their glucose too high and then they're crashing.

And the paper showed that the extent of post-meal dips, the crash after the spike, was predictive of 24-hour energy intake and cravings for carbohydrates.

And this makes sense.

If you crash low, that is a signal to your body, we have to get our glucose back up and it will drive you to eat less.

high-energy foods, carbohydrate-rich foods, and cravings.

So one of the best things we can do, I believe, from my personal experience, from members' experience, and with some data to support this, is that one of the adjuncts we can use to manage our cravings is actually to lower the extent of our spikes so that we crash less.

And so that was a fascinating study looking at CGM data.

Huberman Lab
Dr. Casey Means: Transform Your Health by Improving Metabolism, Hormone & Blood Sugar Regulation

And now they're all โ€“ the latest gen of each of them are all Bluetooth now, so no more scanning, which is kind of nice.

Huberman Lab
Dr. Casey Means: Transform Your Health by Improving Metabolism, Hormone & Blood Sugar Regulation

And the answer is yes.

Huberman Lab
Dr. Casey Means: Transform Your Health by Improving Metabolism, Hormone & Blood Sugar Regulation

There are several different โ€“

um, analytes that we're going to be able to track.

And, uh, Abbott, which is one of the three main manufacturers of CGMs has announced that they're, they have a new product called the lingo, which is going to actually be able to measure ketones, lactate, and alcohol.

Um, continuously, which is pretty interesting from like a metabolic comprehensive metabolic standpoint, different sensors for each, not all in one.
