Go ahead, contract.

Okay.

Maybe.

It's a muscle.

Skeletal muscle is the only organ system that you have voluntary control over.

That's it.

Now, if you decide to not hear what I am saying, then if you are someone who has a genetic propensity, maybe you have, I don't know, when you overeat, you get high triglycerides, or you choose not to exercise, we will start to deteriorate your brain

because contracting skeletal muscle is an endocrine organ.

Not only does exercise increase blood flow to your brain, I just wrote a narrative review with a colleague of mine, Louisa Nicola, amazing.

We looked at the influence of resistance training and brain function.

I cannot restore your brain, but I'd love to be able to prevent from the connections to become weaker and weaker and weaker.

So,

You decide not to exercise.

I can do nothing for your brain.

Eventually, you might forget, I don't know, your neighbor's name, your kid's name, your...

anything, what you did, any meaningful memory, if we don't address your brain now, then the potential outcome is clear, right?

Two-thirds of Alzheimer's, the majority of dementia is Alzheimer's dementia, which plays a role in

metabolic regulation, type 3 diabetes of the brain.

If your skeletal muscle is unhealthy, you are likely having not only skeletal muscle insulin resistance, but brain insulin resistance.

No such thing.
