It had been like voted as America's top personal trainer and I was going to all these conferences and speaking and I was racing an Iron Man triathlon and I was building my business and you know writing books and doing the podcast and just all over the map but I wasn't a very present

father and husband. Welcome back to the Bossway Podcast. I'm Natalie Alice and I'm your host for this episode. I'm so excited to introduce you again to Ben Greenfield.

He is a biohacker, nutritionist, physiologist, fitness coach, competitive athlete, and New York Times best-selling author of 13 books, including the wildly popular titles Beyond Training and Boundless.

So Ben was actually on the podcast, I think it was about five years ago now and it was a really, really popular episode and I wanted to bring him back to talk about anything that might have changed in the health industry, all of the latest diet fads, what we think about fasting.

We also get into a lot of topics around women specifically, whether it's fertility,

rage and of course 80% of the research it's done anyways is done on males not female is the

However if you look at the actual research on females

then once you exceed around 12 hours you see a down regulation of Kispetin, which is technically a

peptide, and that causes a lowering of FH and L.S.H to key fertility regulating hormones. And so you tend to see almost like this message that a woman's body gets once she gets past 12 hours of not eating that it's a time of starvation or famine and not a good time to bring a baby into

the world even if you're not planning on having a baby. So it kind of down regulates a lot of the stuff

you'd need for libido, for hair, for skin for skin for nails for healthy cholesterol levels and you

know it's not as though you shouldn't fast like almost every blue zone almost every

longevity hotspot has some semblance of religious fasting or some kind of
