SHOW NOTES:

  • (11:16) Our brains determine our food intake and regulate our energy expenditure, in a way that works best in our ancestral environment, but not in our modern environment.

  • (24:33) We consume calories for many reasons, hunger being just one of them. Likewise, satiety is just one of many reasons we stop eating.

  • (34:40) As a rule of thumb, eat a diet of omnivorous whole foods that are lower in calorie density.

  • (49:56) Fiber is not an essential nutrient.

  • (58:35) Nutrient-to-energy is important to health, but once you have adequate intake, there's not much benefit in taking in more.

  • (1:04:46) Most people in the US are more susceptible to obesity than others. Whether or not they actually become obese comes down to the environment they choose.

  • (1:15:31) Blood pressure, on a genetic level, doesn't typically change as one gets older.

Okay, Stephen, Guilla Nae, back again, PhD, how's it going?

0:04.8

I'm good, thanks for having me on again.

0:06.8

Yeah, well, I want to go back to the basics of my peak human.

0:10.4

I just love talking to nutrition nerds about things and people who are just in the

0:15.8

literature doing studies writing great books you know that's what I love to do and I hope

0:21.0

the audience loves that as well we going to answer some questions I think that are pertinent

0:26.4

to the audience and not just down in the weeds, right? Like lately people go, how do I be

0:31.0

healthy, right? How do I like lose a little fat you know have a

0:34.1

little better body composition right isn't that pretty much on everyone's mind you

0:38.2

can go really deep in the weeds but tell the audience who you are give us a little recap of Hungry Brain because on the first episode we went into your book Hungry Brain and just a little recap what you're into what you're doing lately.

0:52.0

Yeah, so my name is Stephen Giena. My background is in

0:56.7

neuroscience and obesity research and I was in the academic research world for about 11 years and ultimately decided not to stay in academic research and since then I've kind of maintained a partial role as a science communicator.

1:15.1

In other words, I'm doing a few different things, but one of them is continuing to be a science

1:19.3

communicator, particularly around the issue of obesity and related metabolic issues.

1:26.0

And yeah, the hungry brain comes out of my kind of being in that field of research and seeing all of the really important things that were coming out of it and weren't getting translated to the public and I feel like I'm kind of the lucky person who got to write that book which was the book that needed to be written at that time to help people understand the link between the brain and body fatness, which I think is not necessarily intuitively obvious to people but it helps to recognize that the brain is the organ that generates all behavior and so if you think any behavior is related to body fatness like eating behavior like physical activity

2:14.6

behavior sleep stress anything like that then you have to accept that the

2:20.9

brain is playing a central role in that.

2:23.4

And furthermore, the brain is the only organ in the body that contains a regulatory system,

2:28.2

only, I should say, only known organ that contains a regulatory system for body fatness.

2:35.8

Yeah, so I was the person who got to write that book.

2:38.5

Yeah, I think that's about all I have to say about it.

2:41.8

All's a great book, I suggest say about it. All is a great book.
