Yasmin provides a historical context, comparing modern wellness trends to past health practices such as bloodletting in the 1700s and John Harvey Kellogg’s “electric light bathing” in the early 1900s. She highlights how each era has its own set of health fads aimed at defying illness and promoting longevity.
Notable Quotes:

The Intersection of Wellness and Longevity
Timestamp: [04:17] - [08:22]
Yasmin and Natalie discuss the current administration’s focus on health policies and the proliferation of supplements promising longevity. The conversation shifts to Timothy Caulfield, a professor and research director at the Health Law Institute, who delves deeper into the merging of wellness culture with the quest for longevity.
Notable Quotes:
- Natalie Brennan: “Every day I [see] a different supplement promising to improve me somehow.” ([04:34])
- Timothy Caulfield: “There's this idea that if you're not doing this, there's something wrong with you.” ([05:06])
Biohacking: Science or Hype?
Timestamp: [05:34] - [13:32]
Timothy Caulfield explains the concept of biohacking, distinguishing between its original meaning—incorporating technology into the body—and its modern interpretation involving supplements and extreme wellness practices. He critiques the lack of substantial scientific evidence supporting many biohacking claims.
Notable Quotes:
- Timothy Caulfield: “Biohacking now... includes using some kind of technique or procedure or supplement in order to optimize yourself.” ([05:34])
- Timothy Caulfield: “There is no good evidence to suggest that cold plunges are going to have a dramatic impact on your health.” ([06:45], [08:22])
The discussion includes examples like cold plunges and supplements, highlighting the discrepancy between popular beliefs and scientific validation. Yasmin shares her personal experience with cold plunges, enjoying the immediate benefits but recognizing the lack of long-term scientific support.
Notable Quotes:
- Yasmin Tayag: “I have to admit I have done the cold plunge. I was very skeptical going in, but I really enjoyed it.” ([08:22])
- Natalie Brennan: “I love to jump into cold water... it was the just sweetest moment of my year so far.” ([10:10])
The Placebo Effect and Perceived Benefits
Timestamp: [11:08] - [18:39]
Natalie introduces the concept of the placebo effect, referencing Henry Beecher’s 1955 study and a Harvard Medical School study that found the placebo effect can be up to 50% as effective as real drugs. They explore how belief in a practice, like cold plunges, can result in perceived health benefits regardless of scientific backing.
Notable Quotes:
- Natalie Brennan: “The placebo effect was up to 50% as effective as real drugs.” ([11:37])
- Yasmin Tayag: “If you believe it's gonna make you feel awesome, it will.” ([12:31])
Timothy cautions against attributing longevity to such practices, emphasizing the importance of enjoying activities for their immediate benefits rather than unrealistically expecting them to extend lifespan.
Notable Quotes:
- Timothy Caulfield: “But the promise here is actual sort of biological change, right, that it's going to have a measurable impact on how long you live. And we just don't have good studies to back that up.” ([08:58])
Scienceploitation and Public Understanding
Timestamp: [13:32] - [21:49]
Timothy introduces the term scienceploitation, describing how legitimate scientific language is co-opted to market unproven products. He uses stem cells as an example, showing how their scientific potential is misrepresented in consumer products to create a false sense of legitimacy.
Notable Quotes:
- Timothy Caulfield: “Scienceploitation has become a very, very common marketing ploy. In fact, I think it's almost universal now.” ([16:32])
- Timothy Caulfield: “Assume nothing works.” ([16:57])
He advises consumers to adopt basic, evidence-based health practices such as not smoking, exercising, eating healthy, and building strong communities, rather than falling for high-tech biohacks with dubious efficacy.
Notable Quotes:
- Timothy Caulfield: “The best diet is the diet that's healthy, sustainable, and works for you.” ([09:05])
- Timothy Caulfield: “You don't smoke, you exercise, you know, move, just move.” ([17:32])
Impact on Public Health and Mistrust
Timestamp: [21:57] - [32:56]

Notable Quotes:
- Timothy Caulfield: “...building communities that foster those basic things.” ([32:19])
- Timothy Caulfield: “Aging shouldn't become a contest, you know, that you suffer through to get to the finish line.” ([37:01])

Notable Quotes:
- Timothy Caulfield: “The wellness industry... they're exploiting that issue.” ([28:25])
- Timothy Caulfield: “We have to try to fix the problem, not sell products on the back of the problem.” ([28:47])
Navigating Uncertainty and Embracing Science
Timestamp: [32:56] - [39:33]

Timothy emphasizes embracing the scientific process, recognizing its evolving nature, and avoiding the trap of seeking quick fixes.
Notable Quotes:
- Timothy Caulfield: “Science is a process, right? And if you use that scientific process to come to a conclusion 20 years ago... that's science working, right?” ([33:45])

Key Takeaways:
- Historical Context: Longevity and wellness trends have evolved over centuries, often lacking scientific validation.
- Biohacking Skepticism: Many modern biohacking practices, such as cold plunges and supplements, are popular but lack substantial scientific evidence regarding their impact on longevity.
- Scienceploitation: The misuse of scientific terminology to market unproven products misleads consumers and undermines trust in legitimate science.
- Public Health vs. Individual Pursuits: Emphasizing individual optimization can detract from supporting essential public health initiatives that have historically proven to extend lifespans effectively.
- Embracing Uncertainty: Accepting the inherent uncertainties in health and aging, and relying on evidence-based practices, fosters a healthier and more sustainable approach to longevity.
Final Thoughts:
The episode underscores the importance of distinguishing between genuine scientific advancements and the hype surrounding modern wellness trends. By focusing on proven health practices and fostering community well-being, individuals can pursue a healthier, longer life without falling prey to unfounded biohacks.
