Episode 45: Women’s Health, Fitness, and Cycle Syncing with Ingri Pauline

Episode 45: Women’s Health, Fitness, and Cycle Syncing with Ingri Pauline

May 23, 2022

My guest on episode 45 of the Science & Chill podcast is Ingri Pauline. Ingri is a weightlifting coach, National Strength and Conditioning Association-certified strength and conditioning specialist, and certified nutrition coach. Ingri is unique in that she only works with women, specializing in fitness and nutrition during different transition periods during women’s lives including fertility, pregnancy, postpartum, perimenopause, and postmenopause.

Ingri uses a concept called cycle syncing to optimize the work productivity and athletic performance of her clients, which involves strategically using hormonal fluctuations during phases of a woman’s menstrual cycle to enhance work output. The topic of cycle syncing dominates most of this episode and there is really some fascinating information to be gained here — not just for women, but also for their partners. Trust me, I was taking dutiful mental notes during this entire episode.

If you’re not a woman, you’re probably thinking that this episode may not apply to you, but trust me, there is a ton of great information to be gained from Ingri that men, women, or any other partner to a woman can use to support her. Ingri is also just incredibly knowledgeable about strength, conditioning, and nutrition, and we chat plenty about these topics during our interview.

Episode 44: Optimizing Biomechanics, Healthy Running Habits, and Choosing the Right Footwear with Dr. Heather Vincent

Episode 44: Optimizing Biomechanics, Healthy Running Habits, and Choosing the Right Footwear with Dr. Heather Vincent

May 10, 2022

My guest today is Dr. Heather Vincent.

Dr. Vincent is the Director of Research and Director of the UF Health Sports Performance Center (SPC) in the Department of Physical Medicine and Rehabilitation (PMR) in Gainesville Florida. She is an active researcher of the health benefits of exercise, using physical activity to prevent injury and fight diseases like obesity and osteoarthritis. She is active at the national level with organizations including the American College of Sports Medicine and the Osteoarthritis Research Society International. Since 2008, the SPC has been serving people from all over the USA and internationally. They are quite literally one of the premier sports performance and rehab centers in the entire country, and this is something I can attest to on a personal level. This episode of the podcast was recorded on the back end of my visit to the SPC to undergo a comprehensive running gait and form analysis as well as a long discussion with Dr. Vincent on how I can improve my running form for better health and performance.

Unfortunately, I have been a frequent visitor to see Dr. Heather Vincent’s husband — who leads the running medicine clinic at the University of Florida — to deal with multiple running-related injuries. I have also done another previous gait assessment with Dr. Vincent and her team back in 2018 when coming back from injury. The precision and attention they gave me were unprecedented, and the amount I learned from Dr. Vincent during both of my visits to the SPC is incredible. Getting to speak with her about my results and then delve into a good deal of running-related topics was an extra special treat.

In the first 45 minutes of this episode, Dr. Vincent and I review the results of my running gait analysis. For this reason, I highly encourage you to check out the video of this episode on YouTube or find the corresponding video and images in the show notes to this episode, as it will make following along with what we are saying much easier. But no worries, if you’re unable to watch, there is still a lot of great information to be gleaned from listening to our chat about my running form.

In the second half of the podcast, we talk about healthy running habits, how runners can optimize their form for injury reduction and faster and healthier running, and how to select the best running shoes for you. Dr. Vincent also answers some of the questions posed on Twitter by my audience on several running-related topics. If you are a runner or just interested in improving your own biomechanics and strength, you are going to love this episode.

Episode 43: Supplements and Lifestyle Strategies to Maximize Healthspan and Lifespan with Dr. Brad Stanfield

Episode 43: Supplements and Lifestyle Strategies to Maximize Healthspan and Lifespan with Dr. Brad Stanfield

April 7, 2022

My guest on this episode is Dr. Brad Stanfield. Dr. Stanfield is a medical doctor trained in New Zealand who has a particular interest in optimizing healthspan and lifespan through the use of nutritional and lifestyle interventions. Dr. Stanfield is also quite the expert in supplements with the potential to enhance healthspan and lifespan and, as you will hear in our conversation, approaches supplementation in an incredibly evidence-based way that I really admire. 

In this episode, we talk about what healthy aging and lifespan are, the best ways to promote healthspan and delay aging, the supplements that Dr. Stanfield recommends or is excited about, the supplements that he has stopped taking and the various reasons why — a very interesting part of our conversation, as well as some of the recent controversies in longevity research which Dr. Stanfield has played a role in bringing to the public eye (along with my previous guest Dr. Charles Brenner).

I first became aware of Dr. Stanfield after stumbling upon his awesome YouTube channel where he does comprehensive breakdowns of aging research and supplements. I really encourage you to give him a follow on YouTube and other social media, because he’s producing great content.

If you enjoy this podcast and would like to support it, there are several ways to do so. The first way is by becoming a supporter of Patreon. With Patreon, you can support the podcast with a monthly donation at any level you’d like. You can start showing your support right now by going to patreon.com/bradyholmer or checking the shownotes for a link to my Patreon page.

You can also make a one-time donation to help support the podcast through PayPal or Venmo. These support options can be found on my website by going to bradyholmer.com/donate. There’s also a link in the shownotes to the support page. 

Finally, checking out the podcast sponsors is also a fantastic way to show your support. There are two partners for today’s podcast, both of which are products I use frequently and absolutely love.

The first is LMNT electrolyte drink mix. LMNT is a sugar-free, carbohydrate-free and tasty drink mix containing scientifically-based amounts of sodium, potassium, and magnesium. The single serve packets are great to add to water for any time around a workout or just to have throughout the day. I’m routinely using about 3 of these each day. LMNT comes in a variety of flavors including citrus salt, raspberry, and watermelon. You can try a free 8 pack sampler of LMNT by going to drinklmnt.com/scienceandchill or checking the shownotes for a link to this special offer.

I’ve also partnered with health via modern nutrition (HVMN) to bring a special offer for my audience on their brand-new ketone IQ ketone drink. Ketones are sometimes called the “fourth fuel” and can be used by our muscles, heart, and brain for energy. With exogenous ketone drinks like ketone IQ, you can rapidly elevate your blood ketones and put your body into a state of ketosis. Studies have found — and I have experienced — that taking ketones can help with mental performance and clarity, athletic performance, and maintain energy levels throughout the day. 

If you have not yet tried ketones, I really encourage you to give ketone IQ a try. You can get 10% off your order of ketone IQ by going to their website using the link in the shownotes and entering the code BRADY10 at checkout. Again, use the link in the shownotes to learn more about ketone IQ and when you order, enter BRADY10 at checkout for 10% off your order.

Episode 42: NAD+ Metabolism in Health & Disease and Longevity Science Controversies with Dr. Charles Brenner

Episode 42: NAD+ Metabolism in Health & Disease and Longevity Science Controversies with Dr. Charles Brenner

March 10, 2022

My guest on episode 42 of the podcast is Dr. Charles Brenner

Dr. Brenner is the Alfred E Mann Family Foundation Chair in Diabetes and Cancer Metabolism at City of Hope National Medical Center.  In 2004, Brenner discovered nicotinamide riboside (NR) to be a vital precursor of nicotinamide adenine dinucleotide (NAD+), which is made available by nicotinamide riboside kinases (Nrks) that are conserved between yeast and humans. In 2007, Dr. Brenner’s lab discovered a second pathway by which NR is converted to NAD+ and showed that NR can extend the lifespan of yeast cells by virtue of elevating NAD+ levels and increasing the activity of the NAD+-dependent Sir2 enzyme.

In the past decade, Dr. Brenner has made multiple seminal contributions to NAD+ metabolism, which include engineering a yeast strain to convert inexpensive NAD+ precursor vitamins into NR, solving the crystal structure of human Nrk1, developing the methods for quantitative NAD+ metabolomics, and demonstrating the activity of oral NR in animal models of fatty liver disease; obesity; type 2 diabetes; diabetic and chemotherapeutic neuropathy; heart failure; and central brain injury. Dr. Brenner also led the first clinical trial of NR, which established safe oral availability in humans. He is currently focusing on the maternal and neonatal effects of oral NR and translating animal discoveries into evidence-based safe, human clinical practice for human conditions of metabolic stress.

Dr. Brenner is clearly a well-credentialed scientist, but my main impetus for inviting him to come on the podcast is his recent public criticisms of the longevity field. In particular, Dr. Brenner has several recent posts in which he has directly called out prominent longevity scientist Dr. David Sinclair for what Dr. Brenner describes as spreading misinformation regarding what we know about aging and whether or not we can slow or reverse aging. We spend the last 20 minutes or so of the podcast discussing his critiques and where he believes scientists in the longevity field may be overstepping.

Other topics that we get into include some basics on human metabolism, nicotinamide adenine mononucleotide (also known as NAD) and the importance of the NAD system in physiology, what types of things perturb the NAD system and how this may contribute to diseases and aging, and ways we might be able to boost the NAD system through diet and supplementation.

I will say that at times, we got pretty technical in this podcast, and Dr. Brenner gets into some of the more complex biochemistry surrounding metabolism and the NAD system. But I really encourage you to listen to everything we chat about, because Dr. Brenner is such an eloquent speaker about these topics and I think that even if some concepts are higher level, you’ll learn a lot about biology and physiology through what he has to say — I surely did.
