Exactly.

But the critical thing is how does it work? For example, how do you know there is somebody coming to visit you when you are in the house or apartment? that person either rings the doorbell or knocks on the door and you know there is somebody outside.

And then you can, if you have a camera, you know who it is and you can decide whether to answer it or not.

Every cell in the body, whether we had about 30 trillion cells in the body, every cell in the body can use glucose to produce energy.

But glucose has no way of letting the cell know I'm outside.

There is no doorbell for glucose to ring.

That is the job of insulin.

Should these things play a role in diabetes prevention and management? But do you think, or do you think people are getting it wrong?
