Increased intestinal permeability may lead directly to increased hunger, and a higher bodyfat setpoint.

In yesterday's Part 3 in the Body Fat Setpoint series, Stephan lays out his theory about how leptin resistance occurs, and how that affect out body fat setpoint. It's a little bit dense, so I decided to summarize it to the best of my ability here, as well as incorporate some of my own thoughts:


  • Increased intestinal permeability allows inflammatory substances, such as LPS* (lipopolysaccharide), to cross the gut barrier into our body.
  • The inflammatory substances irritate many tissues, including the hypothalamus. The hypothalamus is the main site of leptin's action. Leptin is a hormone which causes increases in energy expenditure and reduced appetite.
  • Irritation of the hypothalamus causes it to become leptin resistant, which means that the energy-increasing/appetite-suppressing effects of leptin are blocked. We get more tired and hungry.
  • There are many things that are known to increase gut permeability: gluten, lectins from grains, legumes, and nightshades(tomato/potato/eggplant), certain substances in dairy, alcohol, capsaicin(hot peppers), saponins, abnormal gut flora, omega 3:6 imbalance, and much more.
  • A paleo diet eliminates nearly all of these offending substances, which helps improve gut barrier integrity.



*Lipopolysaccharide is produced by gram-negative bacteria, and is one of the main component that the immune system uses to recognize these pathogens. LPS causes a strong activation of the immune system.

Body Fat Setpoint by Stephan Guyenet

Hey guys, I hope you're all having a great winter break! I just wanted to share with you a series of articles, written by a fellow husky! He is a graduate student who received his Ph.D in neurobiology from the UW in 2009.

His name is Stephan Guyenet, and he is the writer of Whole Health Source. His posts are some of the most thought-provoking and interesting that I have read, and he takes a very objective and scientific approach to health, all while keeping posts readable and interesting.

Below is a series in which Stephan discusses the concept of our body's set point, what might affect it, and how to change it. I hope you guys read and enjoy it.

I wish you all a Merry Christmas!

Finals Week/Winter Break WODs

Hey guys, we won't be having training this week due to finals. Study hard, ace your finals, and have an amazing Winter Break! Enjoy the time off, but try to stay active, don't let all of your hard-earned progress go to waste just because you're not going to classes for two weeks.

There are also some more WODs at the end that require some basic equipment such as a pullup bar, dumbells, or jump rope.
