In this episode, I sit down with internal medicine physician Dr. Abud Bakri to talk about the thymus, the small gland on top of your heart that trains your immune system and starts shrinking as soon as you hit puberty. You’ll hear what speeds that shrinkage up, from birth control and testosterone therapy to chronic infections, stress and a leaky gut, why Korean eunuchs lived longer, and which blood markers, like the ratio of helper to killer T cells (CD4-to-CD8 ratio), give you a window into how your thymus is doing.

We get into thymulin and zinc, thymosin alpha-1, the Russian thymus extract Thymalin, and whether eating sweetbreads does anything at all. You’ll also hear my bedtime stack of epitalon and Pinealon, why Abud shines red light on his sternum, the overlooked link between the thymus and testosterone, why he takes 40 times my dose of body protection compound 157 (BPC-157) for injuries, and the red flags to watch for before you inject any peptide. We also cover natural killer cell treatments, the libido peptide being tested for weight loss, and why Abud thinks lactoferrin and colostrum are about to catch on.

The Little-Known “Throwaway” Gland That Is CRITICAL For Immunity (& The Unexpected Peptides To Support It) - With Abud Bakri

Full show notes: BenGreenfieldLife.com/lowcarbhighcarb

In this episode, I'm re-airing the first debate ever held on the Boundless Life podcast, with repeat guest Jay Feldman and Duke obesity medicine physician Dr. Eric Westman going head to head on whether your cells run better on carbohydrates or fat. The carbs-are-good, carbs-are-bad argument has only gotten louder, and this is still the best version of it I've heard.

You'll hear Jay's case that burning fat creates more oxidative stress and drives up stress hormones like glucagon and cortisol over time, and Eric's case from decades of reversing type 2 diabetes in his clinic. We get into the KetoSAge study that pulled keto-adapted women out of ketosis, the KETO Trial on keto dieters with very high LDL cholesterol, what a failing heart actually burns, and why keto adaptation can take months.

We close on the membrane pacemaker theory of aging, survival versus thriving, how I scale my own carbs to training and travel, and the three carb levels Eric lays out inEnd Your Carb Confusion. Whether you eat keto, high-carb, or somewhere in between, this debate will sharpen how you think about fuel.

The High Carb vs. Low Carb DEBATE: Which One Wins For Your Metabolism? With Dr. Eric Westman & Jay Feldman

Full show notes: BenGreenfieldLife.com/thyroidhealth

In this episode, I'm re-airing one of the most comprehensive thyroid conversations I've ever had, with repeat guest Dr. Amie Hornaman. Six doctors told her she was normal while she gained 25 pounds in contest prep, and the seventh finally found the goiter.

You'll hear why thyroid stimulating hormone (TSH) on its own misses most of the picture, how reverse T3 can block your active thyroid hormone at the cell door, and why only 2% of hypothyroid patients do well on T4 alone. We get into T2, the thyroid hormone almost nobody talks about, and the Thyroid Fixxr® (use code BEN10 for 10% off) I took to Italy.

Dr. Amie also covers what years of low-carb eating does to T3, whether animal glandulars help or backfire, where iodine and selenium fit, the peptides she uses for Hashimoto's, and why testosterone matters so much for women. If you've been told your thyroid labs are normal and you still feel terrible, this one is for you.
