I am a ghrelin addict.
Ghrelin is a hunger hormone. Your body secretes it when you haven't eaten for some time. It makes you hungry, and blood levels plummet once you eat.
Yet ghrelin is so much more than hunger.
Ghrelin is neurotrophic. It enhances learning and memory -- in fact, it is "essential for cognitive adaptation to changing environments and the process of learning."
Ghrelin stimulates the secretion of growth hormone.
Ghrelin increases cardiac output.
Ghrelin increases the concentration of dopamine in the substantia nigra, the brain's center of reward and addiction.
That is why ghrelin is a rush.
Ghrelin is why hunger motivates…

Great article. I find that I need to be mildly hungry to perform at my best too.

I think a lot of the Paleo community is becoming addicted to ghrelin. Intermittent fasting has grown greatly over the last year.

I never really thought I'd read a scientific article verifying my addiction to hunger. I've heard of great Japanese warriors self inflicting life-long near starvation and, while that's reassuring, I haven't heard the same of intellectuals. I'm just aware of my body and notice that I am both more physically energetic and mentally acute when I'm hungry. I never connected that rush to ghrelin. Thanks for the insight. I am not anorexic either. I eat plenty of high fat foods every day but I just enjoy skipping meals quite frequently too. I suppose between that and low carb I stay pretty thin.

Peggy:
It's nice to be able to function at such a high level, for so long, without crashing, isn't it?
The great part is that since I wrote this article I've become much more attentive to my diet (high-fat paleo/primal, like you), and I can last a lot longer. Â And I don't think my calorie intake has gone down, much...I eat epic meals when I finally do break my fast.
I loved your anecdote "Bacon Makes You Fat??!!", by the way.

Yeah, I wouldn't say my caloric intake has gone down either. I have days when I seem to be making up for lost time and then other days where I'm just not into eating. It evens out, I think.
I'm glad you liked that story. It's sad but true, and a little bit funny. đ

Managed to find this site doing a search for "beta oxidation." It really is an excellent resource. Of course I have been familiar with Paleo eating and have been a "low carber" for some time but thanks for explaining the role of Ghrelin in a completely different way. I'd always considered it a bit of a PITA hormone, serving no good purpose really, but reading your post, will make me relish this little hormone!

The article gave me a much needed change of perspective on fasting - a kick up the **** to get I.F.-ing again! Thank you

Yes, ghrelin most definitely exists for a very good reason...it's not just trying to make you fat. Â It's trying to make you get off your butt and go spear a mammoth. Â Unfortunately that motivation tends to get short-circuited, in modern times, by the refrigerator or Taco Bell.

It's worth it.

I watched a movie about an artist- a starving artist, but not because he did not make money. He said something that makes more and more sense to me: a painter must be hungry to create art.
Now, I never start a painting on a full stomach. I never solved a problem in a painting on a full stomach.
You have to be a bit miserable, a bit driven, so art can work.

Many people have come to this realization instinctively, but it's very interesting to know the biochemistry. At least I think so!
It's also interesting when a metaphor crosses back into literal truth.

As far as learning goes, Ghrelin also acts on the hippocampus to enhance learning.

Me too!! I'm glad to get a little better understanding of the reason behind the extra focus and motivation. Interesting read! Thanks!
