Date: August 26, 2025
Host: Natalie Kitroeff
Guest: Elizabeth Dunn (Food Writer)

Overview

This episode explores how protein became the dominant obsession in American nutrition, tracing its journey from a niche bodybuilding supplement to a ubiquitous ingredient in mainstream food marketing and everyday diets. Food writer Elizabeth Dunn discusses why protein has become a cultural and commercial phenomenon, the science behind its appeal, the rise of “protein-maxxing” influencers, and the effects—both beneficial and questionable—of an ultra-processed, protein-focused food industry.

Key Discussion Points & Insights

1. The Emergence of America’s “Protein Era”

• Protein’s ubiquity: Everywhere from social media to supermarket shelves, protein is front and center.
  • “It's everywhere. You simply cannot escape the protein boom.” — Natalie Kitroeff [01:18]
  • Protein is now being added to traditionally non-protein products (e.g., chips, soda, even popcorn).
  • Influencers on platforms like TikTok and Instagram focus heavily on protein intake and high-protein recipes.
    • “As the protein queen, I do need to try Khloe Kardashian's Protein Popcorn. These legendary chips. 20 grams of protein. Frosted lemonade, protein soda. 90 calories, 20 grams of protein per can.” — Elizabeth Dunn [03:01]
• Product proliferation: The number of products labeled “high-protein” has quadrupled in the past decade. [03:01-03:37]

2. Protein: The Nutritional Essentials

• What is protein?
  • Protein is a macronutrient essential for body function, growth, and repair.
  • Distinct from carbohydrates and fat, as it’s used to build and repair tissue, especially muscle. [04:25]
• Previous lack of concern:
  • Historically, protein deficiency wasn’t on the radar in the U.S. unless due to severe malnutrition.
    • “It was pretty much assumed that you were getting as much protein as you needed.” — Elizabeth Dunn [04:37]

3. The Cultural Ascent of Protein

• Historical timeline:
  • 1950s: Protein powder emerges for bodybuilding niche.
  • 1990s: Fitness culture goes mainstream; high-protein diets like Atkins and South Beach popularize protein for weight loss.
  • “The really big inflection point was when protein started to be understood as a tool for weight loss.” — Elizabeth Dunn [06:07]
• Persistence beyond fads:
  • Even as diets fade (e.g. Atkins, South Beach), focus on protein remains strong, surging especially during the pandemic amid heightened interest in health, home cooking, and self-optimization. [06:47-07:51]

4. The Influencers & Self-Optimization Movement

• Rise of influential voices:
  • Online communities and fitness personalities (CrossFit, “strength training feminists”) push high-protein lifestyles.
  • “What we aren't going to do is tell the world that muscle is inherently masculine because it's not.” — CrossFit influencer [08:38]
  • Notably, two prominent voices:
    • Andrew Huberman: Stanford neurobiologist, self-optimization advocate, huge podcast.
    • Peter Attia: Doctor, longevity expert, podcaster, espouses high-protein, high-exercise regimes.
• Lifestyle impact:
  • Their followers (“Huberman husbands”) methodically optimize diet, exercise, and sleep, centering protein.
  • “They are probably taking Omega 3 supplements... there's a lot of very intentional workout routines. They're wearing Oura rings for sure.” — Elizabeth Dunn [10:33-10:48]

5. How Much Protein Do You Really Need?

• Standard recommendations:
  • 0.8 grams per kilogram of body weight per day (e.g., 54g for a 150lb person) — “doable,” attainable with a normal diet. [12:51]
• Influencer-driven targets:
  • Huberman and Attia recommend 2-3 times the standard (100-150+ grams/day), a level hard to reach without engineered products. [13:15-13:59]
  • “The quest for that golden protein to calorie ratio culminates in what is the platonic ideal of the protein bar—the David Bar.” — Elizabeth Dunn [14:25]

6. The “David Bar” and the Protein Arms Race

• The David Bar story:

  • Created by Peter Rahal (previously founded RX Bar).
  • RX Bar: “12 grams of protein in about 200 calories.”
    David Bar: “28 grams of protein in 150 calories.” [22:46]
  • Uses a patented, modified plant fat (EPG) that delivers almost no calories.
  • “EPG is a modified plant fat that moves through your digestive system mostly undigested. So that means that it delivers 92% fewer calories than, like, a normal fat.” — Elizabeth Dunn [20:30]
  • Massive demand: $1M worth sold first week, projected $180M in sales for 2025. [21:24]
  • Endorsed and invested in by Attia and Huberman, who are also involved in its promotion and product development.

• The business move:

  • David Bar’s parent company acquired Epigee, the exclusive manufacturer of EPG, ensuring monopoly over this “magic” ingredient. [23:03]
  • Ambition: Become a “protein platform,” not just a bar company—first extension is frozen cod as a high-protein offering.

7. Is All This Protein Obsession Good For Us?

• Health consequences:
  • “Unless you have a specific kidney issue, we can eat a lot of protein and it's not gonna be bad for you.” — Elizabeth Dunn [25:53]
  • Real risk: By prioritizing protein, people may be missing out on other nutrients and over-consuming ultra-processed foods.
  • The David Bar (and many others) are “the definition of an ultra-processed food… popular at a time when this other major food trend has been unfolding, which is people becoming increasingly skeptical of and worried about ultra-processed foods.” — Elizabeth Dunn [26:37]
  • Nutrition might become about what you're not eating (e.g. fiber, micronutrients) as much as what you are.

8. The Joy (and Spiritualization) of Protein

• Where’s the pleasure?
  • For many, the joy isn’t culinary but lies in “the process of optimizing…moving ourselves just incrementally closer to a physically perfect version of ourselves.” [27:42]
  • Identity and community: The protein lifestyle is tribal and even spiritual for some, with “almost evangelical quality” and “faith-based activity.”
  • “Nutrition fads have their own prophets... a path to righteousness… that goes way beyond losing weight or gaining muscle. For some people, that's what they're really getting out of this.” — Elizabeth Dunn [29:09-30:11]
  • Yet most Americans may still just be hunting for more muscle, a feeling of satiety, or a simple health boost.

Notable Quotes & Memorable Moments

• On the scale of the trend:
  • “The number of food and beverage products hitting the market with a high protein claim has quadrupled.” — Elizabeth Dunn [03:01]
• On the influencers’ vision:
  • “In Peter Attia's view, the goal at midlife should be to build so much muscle that as we naturally lose muscle as we age, you end up in your 80s and 90s with enough muscle left that you're still gonna be able to pick up your grandkids...” — Elizabeth Dunn [11:52]
• On David Bar’s value proposition:
  • “There is no better bar on the planet when it comes to getting more protein with fewer calories. And it tastes absolutely delicious.” — Andrew Huberman, as quoted by Dunn [22:08]
• On the joy of optimization:
  • “There is a lot of joy in the process of optimizing, in this feeling that by consuming foods like the David bar, we're moving ourselves just incrementally closer to a physically perfect version of ourselves.” — Elizabeth Dunn [27:42]
