Podcast Summary: The Thyroid Fixer

Episode 559: How to Fast While Eating Food...Really! The Fasting Hack That Gives You All The Benefits Without the Misery!
Host: Dr. Amie Hornaman
Guest: Dr. Chris Rhodes
Date: September 9, 2025

Overview of the Episode

This episode of The Thyroid Fixer is centered around a groundbreaking approach to fasting—achieving the cellular health and longevity benefits of fasting without extended food restriction. Dr. Amie Hornaman interviews Dr. Chris Rhodes, a nutritional biochemist and creator of the supplement "Mimeo," which claims to mimic the effects of fasting at the cellular level. Together, they unpack the science of fasting, its drawbacks (especially for women and thyroid patients), and how Mimeo offers a practical solution for those who struggle with traditional fasting protocols.

Key Discussion Points & Insights

1. Why Fasting? Health & Longevity Benefits

• Longevity & Disease Prevention:
  • Dr. Rhodes: "Fasting is really fascinating because it's one of the only ways that we know of to reliably extend the lifespan in animal models." (11:41)
  • Fasting not only extends lifespan but healthspan (living disease-free longer), reducing cancer risk, neurodegenerative diseases, autoimmune disorders, and cardiovascular illnesses.
• Cellular Mechanisms:
  • Fasting activates innate "repair, protect and maintenance" mechanisms in cells—namely autophagy, reduced inflammation, improved mitochondrial health, and less DNA damage.
  • Quote: "In a fed state...cells have plenty of nutrients. They're not going to care how efficient their metabolism is...In a fasted state, that really gets flipped on its head." (12:55)

2. Fasting vs. Caloric Restriction

• Fasting’s benefits don’t arise solely from eating fewer calories:
  • Dr. Rhodes: "If we alternate day fast animals but don't reduce their calories at all...fasting still has this lifespan extension effect." (15:26)
• Traditional eating schedules contribute to "chronic dietary inflammation," stressing the importance of meal timing, not just calorie amount.

3. Insulin, Weight Loss & Overnutrition

• Frequent eating keeps insulin levels perpetually high, promoting insulin resistance and fat storage.
• Dr. Amie: "Every single time we eat, when we do this grazing...our body's always pushing out insulin." (18:34)
• Overnutrition accelerates "inflammaging"—chronic low-grade inflammation as we age.

4. Downsides of Traditional Fasting for Women & Thyroid Patients

• Extended fasting windows often lead to inadequate protein intake—crucial for aging women to prevent muscle loss (sarcopenia) and increased frailty.
• Fasting is a stressor; excessive fasting can spike cortisol, which may disrupt thyroid function and hormone conversion.
• Many in Dr. Amie’s audience have found long fasts (16–24 hours or more) difficult, unsustainable, or even harmful.

5. From Research to Supplement: The Story of Mimeo

• Inspiration: Dr. Rhodes became fascinated by fasting’s robust self-repair benefits—yet frustrated that they require such a difficult practice to access.
• Developed Mimeo after identifying bioactive metabolites only present in the blood after 36-hour fasts.
• Dr. Rhodes: "I got very, very into fasting...after around two years, there's a weird element of social isolation that comes along...like, our society is not built for people to only eat every other day." (24:36)
• Eventually, the desire was to give people the benefits of fasting "without having to do this crazy alternate day fasting lifestyle." (25:47)

6. How Mimeo Works: Science & Use

• Study Design: 20-person fasting study (10 men, 10 women) identified a unique set of fasting-specific metabolites.
• Final formula: Four synergistic ingredients (nicotinamide, spermidine, oleoyl ethanolamide, palmitoylethanolamide) that recreate anti-inflammatory and longevity benefits when combined.
• Animal Model: Extended lifespan in C. Elegans by 96% (31:55).
• Dosing Flexibility:
  • Mimeo can be taken with or without food, serving as a fasting mimetic or fasting enhancer.
  • For those fasting, it can deepen benefits and reduce appetite/hunger.

7. Eating Quality Still Matters

• Mimeo improved health markers even with a standardized non-fasting meal, though overall results depend on diet quality.
• Dr. Rhodes: "Eating a burger plus mimeo is probably better than eating a burger without mimeo." (35:35)

8. Female-Specific Considerations

• There is a significant research gap regarding the effects of prolonged fasting in women.
• Shorter fasting periods (14–16 hours) combined with Mimeo may strike a healthy balance for women, mitigating risks linked to over-fasting.

9. Mimeo: Additional Benefits and Clinical Data

• Appetite suppression, improved satiety, better metabolic markers (blood glucose, cholesterol, LDL, oxidated LDL), reduction in biological age by 2.5 years in just 8 weeks (pilot study, 47:23).
• Dr. Rhodes: "Nothing knows how to heal a human body better than a human body...The point of mimeo is really to allow us to activate those regenerative systems...on demand." (41:02 & 41:43)

10. Practical & Ethical Guidelines

• Not recommended for pregnant/nursing women or children (48:19).
• Individual ingredients well-researched; full formulation tested in three human clinical trials.

Notable Quotes & Memorable Moments

• On Social Isolation from Fasting:
  "At a certain point, my sister basically told me, 'Chris, you're gonna live longer, but what is the point of living longer if you have to live less?'" — Dr. Chris Rhodes (24:36)

• On Fasting "Biohacking":
  "There is actually a way to kind of hack fasting and get the benefits without the pain." — Dr. Amie (27:19)

• On Naming Mimeo as an 'Essential', Not-to-Miss Supplement:
  “The one category, it could be called essentials, but I call them my no-dust supplements...die [if] you're going to take these every day because there are so many benefits. Why wouldn’t you?" — Dr. Amie (48:19)

• On Women and Fasting:
  “Too much fasting is actually detrimental on the body. Now you're negating the benefits of fasting by not getting enough protein, raising your cortisol, affecting your thyroid. What I love about this is it's the best of both worlds.” — Dr. Amie (37:54)
