Are seed oils actually harmful? Or is this just another wellness myth gone viral?

In this episode, I sit down with Dr. Bill Harris - leading expert on dietary fats - to unpack the science on linoleic acid, an omega-6 fat found in nuts, seeds, and vegetable oils.

We explore the rise of seed oil fear-mongering, the truth about inflammation, cholesterol, oxidation, and why outcome data—not mechanisms—should guide our thinking.

If you’ve been confused by the seed oil debate, this one’s for you.

In today’s episode, I’m joined by Drew Harrisberg, an exercise physiologist, diabetes educator, and founder of Drew’s Daily Dose.

We dive into the science behind Apple Cider Vinegar (ACV)—does it actually help with blood sugar, weight loss, digestion, and overall health, or is it just another overhyped wellness trend?

We also explore the power of anecdotes in the wellness industry, starting with Belle Gibson’s story and the new Netflix series on ACV. How can we separate fact from fiction when faced with bold health claims on social media?

What we cover:

• ACV and blood sugar – does it really help?

• ACV and weight loss – what does the science say?

• ACV vs. other blood sugar strategies (walking, fiber, etc.)

• Potential downsides – acid, teeth damage, capsules, and more

• How to take ACV without ruining your teeth

• Should Simon take Bragg’s ACV as a sponsor? Ethics of podcast ads

Later, Drew shares a moving tribute to his dog, Dennis, reflecting on grief, love, and celebrating life. We also talk about memory dividends and why showing up for the people (and pets) we love matters.

We wrap up with a shocking magic trick, plenty of laughs, and a classic dad joke.

You may have heard claims that C15:0 (pentadecanoic acid) is the first essential fat discovered in 90 years, a powerful longevity booster, and a game-changer for metabolic health. But how much of this is backed by solid science?

In this episode, I sit down with Dr. Bill Harris, a leading expert in fatty acid research, to critically evaluate the evidence behind C15:0. We break down the population studies linking it to health benefits, the key clinical trials testing its effects, and whether the marketing around Fatty15 is ahead of the actual data.

In this episode, we cover:

Is olive oil really as healthy as people claim? How does it compare to other fats? And how do you choose the best product for cooking and everyday use?

In this episode, I sit down with Drew Harrisberg to break down four new studies covering selenium intake, plant vs. animal monounsaturated fats, workout recovery strategies, and resistance training techniques. But beyond the science, we also discuss a critical issue in health communication—the responsibility of podcast hosts when platforming health claims.

Using recent episodes of Diary of a CEO featuring Dr. Mindy Pelz and Dr. Sarah Berry, we examine how misinformation spreads, why extreme views persist, and how listeners can differentiate science from pseudoscience.

Learn why timing matters less than consistency, whether co-supplements like carbs enhance effectiveness, and if creatine affects blood pressure, fertility, or urine production. This is your ultimate guide to making informed decisions about creatine supplementation.
