His discussion revolves around POMC and melanin.  So the hack is exposure to sunlight.  Not just being out in the sun between 11 and 3pm, but exposure to sunlight, meaning shirt comes off, shorts or trunks replace pants.  And exposure to cold, both, meaning, you'll need to take cold baths.  I knew of bone regeneration in young people from Becker's books.  For example, a kid who has the tip of a finger to the first crease cut off will grow back completely but only up until the age of 11.  

47:00.  Bone doesn't heal; it regenerates completely.  

57:47.  What do I need to do?

And I said, just follow the leptin prescription.  I said go see the sun every day, see the sun rise, get as much sun as you can, but you need to use cold.  You need to start taking cold baths.

58:00.  And he said why?

58:01.  I said, Look, it's not important why, but this is what I'm going to tell you.  Mammals figured out after they came out under the ground that if they get in cold environments, they can make stronger UV light from their own tissues than even the sun provides.  This is what fueled all their evolutionary growth.

58:19.  What?  

58:21.  The process is called wideband semiconduction.  Basically, you take visible light from 250 to 760, you use non-linear Optics, and the things that you use are wide band semiconductors. I said the wide band semiconductors that you know in biology are called hemoglobin, chlorophyll, and melanin.  And, it turns out, for us, the chlorophyll is not a big part of the story; that's the plant side of the story and food's part of the story.  But hemoglobin and melanin, dude, that's the ticket.  I said you need to maximize oxygen delivery and nitric oxide delivery to melanin to renovate it and to create massive amounts of melanin where your body plan put it in.  I guarantee if you have eosinophilic esophagitis that the problem is going to be in the visceral level at the hypothalamic level in your brain.  I can even tell you the tract is going to be in.  I can tell you where the melanin is missing.  So you need to use UVA light and infrared A light through your eye predominantly, and I think it'll go away.  So that's what he did, and 6 weeks later, it was gone after having this for almost 15 years.
