In this premium podcast with Ben Greenfield, Ben answers the following questions about ketosis, Ironman training, nutrition and more:     
Do you use bitter melon to help buffer blood sugar spikes in a effort to continue producing blood ketones? If yes, how important is the timing of taking the bitter melon for this and how much do you take each time?
Have you had any breaks from ketosis where you carb binge?
Please let us know about your experiences with oxaloacetate -- most importantly about the safety of it and how much (in your opinion) it boosted your performance. 
I'm doing your TriathlonDominator.com plan, and am curious as to how you typically train right now... Are you still doing predominantly H.I.I.T. with long Z2 efforts sprinkled in? 
How much does it cost you a month to eat that way? Carbs are so cheap and yummy. 
Is there any advantage to adding hard to find meat like lamb and bison to my diet?
What are your thoughts on barefoot/minimalist  running? ( thinking performance & injury prevention)
Do you recommend anything for me in my first 5K? So far I’ve been working out for the last 2 months, 6 days a week, eating ok, I do cheat but I just pray I make it to the end.
What do you think of Ezekiel bread? I haven’t heard much, but I love bread and people say it is better for you.
I just read some good protein things with brewer’s yeast? Yay or nay?

"Ask Me Anything About Ketosis & Ironman" Premium Podcast with Ben Greenfield

Full show notes: bengreenfieldlife.com/bolt

In this episode, Chandler Bolt and I talk about how we've each landed on almost identical daily systems for running a company, and the one place we still disagree. Chandler makes the case that a book is a business asset rather than an income stream, explains what it actually costs to buy your way onto the New York Times list, and then walks through the routine underneath all of it: a nap he hasn't skipped in years, a morning he refuses to let anyone schedule over, and a phone that geofences itself into work mode the moment he arrives at the office.
 
You'll also hear why he self-experiments relentlessly yet refuses to wear a tracker. We get into the two metrics worth watching if you track nothing else, why the 30-minute nap ceiling is weaker science than you've been told, why a hot tub is harder on fertility than a sauna, what overhead LED lighting does to your afternoon and the BlockBlueLight bulbs I use instead, and why a manual WALKOLUTION treadmill desk beats a motorized one. Chandler also shares the airplane movement trick that got him mistaken for a lunatic by a stranger who later became a friend. Then we close on communication: being a default no, replacing calls with voice memos, and using SocialSweep to surface the connections already sitting in your phone.

How To Build An Ideal Workday With Power Naps, Email Delegation & Deep Work Tactics, Featuring Chandler Bolt

Full show notes: bengreenfieldlife.com/pharma

In this special repeat episode, Dr. Sandra Kaufmann breaks down which pharmaceuticals mimic the effects of things you already do for your health: what replaces a sauna session, what replaces a fast, what replaces a cold plunge (use code BENFORGE for $500 off select products), and what she takes with meals to blunt the damage from glucose spikes. I'm re-airing it now because of a new Nature paper finding that lithium is a naturally occurring brain nutrient, and that losing it may be one of the earliest steps toward Alzheimer's, at a dose in exactly the range Dr. Kaufmann described on this show years earlier.

You'll hear why she prefers pioglitazone over metformin for autophagy, how a Japanese gastritis drug connects to Alzheimer's, and how she worked her way up on an emergency blood pressure medication, starting at a dose that nearly knocked her off her feet and climbing to 100mg with no effect at all. The centerpiece is lithium (code BGL10 for 10% off): why the doses hidden inside popular nootropics are a fraction of what she considers useful, and everything it appears to do beyond mood, from controlling a pore in your mitochondria to building bone and growing new neurons. You'll also get her honest take on gene therapy versus pharmaceuticals, why peptides underperform in an older cell, and which molecule finally knocked astaxanthin off the top of her ranking system.

How to Replace Sauna, Fasting, and Cold Plunge With a Pill (WARNING: Proceed at Your Own Risk!) With Dr. Sandra Kaufmann

Full show notes: bengreenfieldlife.com/505

In this solosode, you'll get the latest on microplastics, spinal disc health, and what a heart scan sees that a cholesterol panel misses. A new seven-day trial pitted five plastic-avoidance strategies against each other, and the results tell you exactly where to spend your effort if you can't overhaul everything at once. You'll hear which plastic sources matter most and what I now take before bed with BrocElite® (use code BEN for 25% off your first month) to help clear microplastics from tissue. Then I get personal about my back. I'll walk you through my full-body MRI results, which show significant degeneration from L1 to S1, and explain why I still have almost zero back pain, from Dr. Stuart McGill's Big 3 to inversion hanging, the couch stretch, the founder stretch from Foundation Training, and my WALKOLUTION® treadmill desk ($100 off, enter your email for a unique code). You'll also learn why running was the only activity linked to healthier spinal discs in a study of more than 4,000 people, and why none of the sports people assume are hard on your back showed harm. Finally, you'll hear what a coronary CT angiography measures that your cholesterol panel cannot, why a 6,061-person study found plaque volume beats any standard risk calculator, what my own scan revealed, and the surprisingly simple thing that appears highly protective even when your plaque is already elevated.
