What's the one thing doctors and patients have been getting wrong about obesity for decades? Okay.

So I obviously was trained in the prevailing paradigm where we basically assume that people are eating too much.

not exercising enough.

So they start to gain weight.

And because of the weight gain in the liver and other places, after a few years, sometimes quicker in some people, sometimes slower in others, they start to have a reduced response when your body reduces insulin.

Okay.

So that process is called developing insulin resistance.

this could possibly happen to you? And did you do the testing and realize that? Oh, yes.

So HbA1c is measuring how much of your hemoglobin has been glycated.

And glycated just means a glucose molecule added onto it.

And it's tested.

And what it shows is how much glucose, what is measuring how much glucose you've kind of had over the last three months.

Okay, so it's kind of like a long-term kind of testing.

Now, there is an issue with HbA1c, right? Because none of these tests are perfect.
