  • NAD / liver toxicity

    Ben had guest on who explained how I could eat Bison/eggs which I need for protein especially for my optic nerves. And yet keep my LDL lower.

    Glaucoma is my eye disease, thankfully a higher protein diet plus nicotinamide ribose NAD, has arrested it.

    I’m 80, exercised, work, and have longevity in my family. Energy is important for my independence.

  • John Jubilee

    I get a lot of good information from Ben but if I know his guest is selling a product I will skip the episode usually. The one with John Jubilee really upset me. The guy claims he can basically cure everything and it gets to the end and the whole time he was selling his product. A lot of integrety there. I’ll probably stop listening after this.

  • I Miss the Ben Greenfield Podcast I Used to Love

    I’ve been following Ben Greenfield for over a decade. I’ve listened to countless episodes, purchased Boundless, and incorporated many of his recommendations into my life. For years, I considered him one of the most valuable voices in health, fitness, and longevity.

    That’s why I’m so disappointed by the direction his podcast has taken lately.

    What once felt like an intellectually stimulating, science-driven show increasingly feels like a platform for religious messaging. Almost every topic some... more

Talking Points

Recent interactions between the hosts and their guests.

Why Fitness, Anti-Aging, Money & Sex Won’t Make You Happy (& The Routine That Builds True Fulfillment), with Vince Del Monte
Q: Did something like that change as you went through this process, as far as what it looked like to actually be connected to God and what it felt like to talk to God?
Del Monte says his faith shifted from familiar, routine prayers to a personal relationship with God. He recalls praying on his hands and knees after his wife ended the marriage and feeling comforted, then building a daily practice of prayer, scripture, journaling, and silence.
The Ultimate Biohacker’s Guide To Pre & Post-Surgical Prep: Technologies, Peptides, Stem Cells, Nutrition, What NOT To Do & Much More, With Dr. Reza Jazayeri
Q: Where do you fall when it comes to the importance of protein, dosing, timing, and amino acids or collagen?
Jazayeri explains that standard protein recommendations are minimums for avoiding malnutrition, not necessarily adequate during surgery and recovery. He emphasizes essential amino acids, especially leucine, to support muscle protein synthesis, and notes that collagen is an incomplete protein for that purpose.
Why Fitness, Anti-Aging, Money & Sex Won’t Make You Happy (& The Routine That Builds True Fulfillment), with Vince Del Monte
Q: What led to losing my marriage?
Del Monte says he avoided addressing repeated conflicts, did not give his wife the time and emotional attention she wanted, and put his business ahead of their relationship.
The Ultimate Biohacker’s Guide To Pre & Post-Surgical Prep: Technologies, Peptides, Stem Cells, Nutrition, What NOT To Do & Much More, With Dr. Reza Jazayeri
Q: How much of a difference does strength training and improving muscular stability before surgery make?
Jazayeri says preoperative strength is a strong predictor of postoperative function. For ACL patients, he aims to reduce the strength deficit between the injured and uninjured leg to below 20 percent, using prehabilitation and, when appropriate, blood-flow restriction or muscle stimulation.
Doctors Gave Him 4 Years To Live: How A Biochemist REVERSED His Heart Disease - With Patrick Theut
Q: Do you think there is a case to be made, especially in the presence of elevated calcium or plaque, for statins or even a PCSK9 inhibitor?
Theut says there may be a case for some people, particularly those with certain APOE variants, and recommends considering genetic testing and other markers. He emphasizes that the appropriate approach depends on the individual.
