Fasting inhibit muscle growth? [22:51] Sheila says: Hi Guys! I'm a 56 yr old woman, very lean and fit (5'5", 120 lbs). I do primarily weight lifting 6x/wk. I eat low carb/higher fat, mostly animal protein, above ground veggies, and healthy fats. I also do intermittent fasting... fasting between 16-20 hrs. I usually lift around 11:30am (I also do Kion Aminos before my workout (while fasted)), and have my first meal around 1pm (a post workout shake), and then 2 food meals. I do prioritize protein making sure to get enough (100-140g). I love my eating style and timing, but I'm wondering if the intermittent fasting could be slowing down muscle growth? I'm specifically trying to make Booty-gains, LOL... and it's going very slow despite training this muscle group 3x/wk. Not sure if it's just my age or what (and the fact that I sit all day other than my lifting and short walk after dinner), but I heard something in a podcast about it being better to eat more frequently for muscle growth...but I hope that's not the case because I love IF. Would love to hear your thoughts on this! Thank you so much! Shannon 2. Controlling Insulin - Risk of Colon Polyps [26:55] Shawn says: Hi Rob, Long time listener of the podcast.  Have read both of your books and really enjoy your perspective on diet, training, and especially your jiu-jitsu journey.  I myself started out with more of a powerlifting template around the age of 28.  Currently I'm 41 and doing more of a crossfit type training session 2 to 3 times a week along with the "old man jiu-jitsu" twice a week.  My question surrounds insulin and glucose levels and colon polyps.  I had my first colonoscopy at 33 due to family history of colon cancer.  They found 1 pre-cancerous polyp the first time around.  Five years later they found 4.  I recall Dr. Steven Gundry making the statement that he never saw a patient that had colon polyps that did not also have a high fasted insulin.  My fasting glucose is usually in the upper 90's.  Never had a fasted insulin test (but plan to).  My hba1c has looked good at around 5.0.  My diet is predominantly lower carb, but have always struggled with performance if I go too low.  I've heard others recommend Metformin for helping keep glucose and insulin levels more in check as well.  Just wanted to get your take on the relationship between glucose, insulin, and the risk of colon polyps / cancer. Love the Q/A format.  Please keep doing what you're doing. BTW, would love to train BJJ with you if the opportunity ever arose. Shawn 3. Basement dwelling = Pretty skin? [32:56] Kristi says: Hi, love the podcast etc. So, I'm a 27 year old female. And I spent most of my youth (junior high, high school, up until I was about 25) fearing the sun and sunburn. I would obsessively wear sunscreen, and I was as white as a ghost. I did catch a couple bad burns in junior high, which horrified me at the time, I didn't want to become one of those monster grandmothers that they showed in the future face cameras. After a bit of college, I spent several years as a literal basement dweller -- I woke up in time to play World of Warcraft with my team at 5 pm. I even did most of my grocery shopping at night. However the problem with this was I was pretty depressed, and I soon learned that sunlight, and sleeping more, can be important factors. When I was about 25 I started coming around to my old enemy, The Sun. This year, my goal has been to get as much sun as possible during the short Canadian summer -- without burning -- an
