You could have all sorts of things that are subtle, but when you correct it, you feel better.

And the FLC syndrome, or feel like crap, really improves.

All right, so let's get into it.

What are the core labs that everybody should know about and should track in their bodies, right?

And what do they tell you?

If you can only run a few tests to truly understand what's going on in your body, what would be giving you the most valuable information and why?

So let's break it down into the big categories of what we track and what we need to track.

The first is metabolic health.

And when I say metabolic health, I mean blood sugar regulation and insulin.

This is what's driving most of the disease in America today.

Heart disease, cancer, diabetes, dementia, aging itself, weight gain, obesity.

I mean, the list goes on.

So the things that we track are fasting glucose, which most doctors will check on your checkup.

We also check A1C, even if you're not diabetic, because it changes slowly.

And as I said, anything from over five starting to increase can be a concern.

And we check your fasting insulin.

which is really important because that's the first thing to go up.

Before your blood sugar A1c go up, your insulin goes up fasting, and it's really important to look at that.

So you want to look at what the optimum range is for blood sugar, not the reference range.

And the optimum range is probably 70 to 85, not like up to 100.
