For more than 10 years, I have been looking at ketones and mitochondria, and it's very clear that ketones can give your mitochondria superpowers.

In fact, I've written about it in a couple of my books. It's in the bulletproof diet. It's in fast this way, and actually the other ones too.

You don't always have to be in ketosis, but when you turn on your ketones, especially at high levels for brief periods, magic can happen.

We're talking better energy, better focus, better endurance, even better hydration.

I've been working with a company called HealthVia Modern Nutrition, or HVMN, that created ketone IQ, a daily ketone supplement drink.

Does have any sugar or stimulants? It's just clean energy for better physical and cognitive performance.

I feel the difference if I'm meditating, if I'm doing neurofeedback, if I'm working out, or just what I need extra energy to do something really intense.

Hey guys, I've got a new cool facts Friday for you. I love doing these things, and it's really just about sharing cool stuff that I think is useful and is certainly interesting.

I hope you enjoyed as much as I do. This cool fact is about how lonely brains crave people. It's particularly relevant right now, because my new book, Fast This Way, just came out.

In it, I talk about how I sat in a cave for four days all by myself with no food. I did that as part of a vision quest, but I did it because I wanted to face my fear of loneliness at the same time.

I faced my fear of hunger, and I learned to overcome both of those, and I share that experience as part of understanding the psychology of fasting.

But this new research is really interesting because we didn't know back when I did this that there are parts of the brain that share hunger and connection.

You've ever been in the situation when you're in a lunch meeting, you're starving, you can't hear a word, your colleague is saying, because you're distracted by food at the table next to you.

It happens because when you're hungry, different areas in your brain light up at the sign of food, and it gets your attention, it's a primal survival response.

Well, researchers found the exact same thing happens in your brain when you see groups of people socializing when you've been deprived of people.

So apparently, just like your brain says, you need this food, it does the exact same thing in the exact same area for social interaction. That means when you're socially isolated, your brain is craving people.

What does it mean for you? We understand how important food is in our lives, and without food, eventually you'd starve and you'd die, but it takes a very long time.

If that same center in your brain lights up for social interaction, this new research says that the impact of loneliness can have a much more significant role in your health than we previously understood.

And I've interviewed a bunch of guests recently on Bulletproof Radio about human connection. Episode 755 is about friendship, 756 is loneliness, and 757 is about social isolation.

So if you're feeling a craving for social connection right now for obvious reasons, at least make it a priority to connect with friends and family via a video chat, and do what you can to get a hug.

It's because it's part of being alive. So do your best to connect right now.
