So when you get stressed, cortisol rises, you are going to break down stored glucose from your liver and put it into your bloodstream so that you can run.
And in the olden days, you would run from a bear.
You would use up all that glucose by yourselves and you would go back to normal.
But in the modern world, you are stressed over and over again.
A bad email, a bad meeting, a doctor's appointment.
The internet.
There's so many things.
And so your body is doing what it's trying to to keep you alive.
And yet we are not in a position to even understand it.
So one thing that I think has to go into this discussion is what really happens to your body when this is, because this is a big key I don't think women get.
Glucose goes into your cell via insulin.
We've talked about insulin resistance a couple of times.
So insulin is a hormone that comes from your pancreas.
You eat food, food gets broken down to glucose, pancreas secretes insulin.
I like to think about insulin as a salesman, knocking on the door of the cell, allowing it to open and glucose comes in.
So in a normal world, glucose levels up, insulin up, knocking on the door, door opens, both of them go down back to normal.
What happens is when glucose is higher longer, and that can be because you're eating foods that have what's called a high glycemic index.
A lot of our ultra processed foods cause a bigger glucose spike.
We're eating more frequently.
We're not getting as much sleep, stress like we just described.
