Episode Overview

In this episode, host Tamsen Fadal sits down with Dr. Amy Shah, a physician and author specializing in gut and hormone health for women, especially during midlife, perimenopause, and menopause. Their conversation dives deep into the changes women experience during these life stages, with a special focus on gut health, nutrition, energy, and belly fat. Dr. Shah introduces her practical "30, 30, 3" tool for daily diet, debunks persistent myths about supplements, and gives actionable strategies to feel better, boost energy, and reclaim bodily well-being in midlife.

Key Discussion Points & Insights

1. Understanding Perimenopause & Menopause Challenges

• Lack of Awareness and Medical Training

  • Many women are unaware of perimenopause until they experience it.
  • Doctors, including OBGYNs, often have little formal training in perimenopause.
  • "Most women just feel like they've never been told that there's this thing called perimenopause... And a lot of times they're dismissed." (Dr. Amy Shah, 02:44)

• Societal Myths

  • Cultural narratives often portray midlife as a downhill slope, but Dr. Shah and Tamsen push back:
  • "You can pivot late in your life. You can find gifts you never knew you had." (Dr. Amy Shah, 03:13)

2. Nutrition During Perimenopause: Common Mistakes

• Undereating is a Major Pitfall

  • Many women respond to weight changes during perimenopause by drastically cutting calories, which backfires.
  • "When you under eat... your body tries to adapt... increased cravings, fatigue, less energy expenditure, and possible sleep disruption." (Dr. Amy Shah, 05:37)

• Noticing New Digestive Issues

  • Bloating, changes in food tolerance, and discomfort become common during perimenopause due to fluctuations in estrogen, which affects the gut microbiome.
  • "When our estrogen levels are all over the place... you’re going to see a shift in gut bacteria." (Dr. Amy Shah, 07:37)

3. Gut Health as the Foundation for Hormonal Wellness

• Estrogen and the Microbiome

  • The gut (specifically the trillions of bacteria living inside it) is significantly influenced by hormonal changes, with direct consequences for digestion and even the immune system.
  • "Our trillions of gut bacteria help our immune system figure out what is friend and what is foe." (Dr. Amy Shah, 09:56)

• Autoimmune Issues and Midlife

  • Autoimmune conditions (e.g., Hashimoto’s) often surface in midlife, largely due to disrupted communication between the gut, immune system, and hormones.
  • Nutrition is the primary method to heal the microbiome, with supplements playing a supportive but lesser role.
  • "Supplements are like buying shoes for the race. Nutrition is how you train." (Dr. Amy Shah, 10:50)

4. The "30, 30, 3" Nutritional Tool

(17:18 onward)

• Breakdown of the Tool:

  • 30 grams of protein in your first meal
  • 30 grams of fiber throughout the day
  • 3 servings of probiotic (fermented) foods daily
  • "You can be on any diet. It doesn't require you to buy anything special... I wanted to do something agnostic; everybody could do, no matter what." (Dr. Amy Shah, 17:22)
  • The aim: stabilize blood sugar, nourish the gut, and reduce cravings.

• Fermented Foods as Probiotic Sources

  • Examples: yogurt, kefir, kimchi, sauerkraut, raw apple cider vinegar, probiotic cottage cheese
  • "Pickled does not always mean fermented." (Dr. Amy Shah, 15:43 & 12:53)

5. Real Talk on Supplements

• Only a Few Are Essential (22:43)

  • Magnesium, Omega-3s, Vitamin D are the key supplements with strong scientific backing for women in menopause.
  • "Those three are like slam dunks—especially at this time of life." (Dr. Amy Shah, 22:43)
  • Get protein, fiber, and most nutrients from food.

• Cautions

  • Be wary of fat-soluble vitamin overload (A, D, E, K), weight-loss pills, or exotic supplements without solid evidence.
  • “We’ve seen a lot more liver damage... because people are overusing supplements without knowing the side effects.” (Dr. Amy Shah, 24:42)

6. Trending Topics: What’s Worth It?

• Creatine: Not a magic pill, it only works if you pair with exercise. (26:01)
• Antihistamines for Menopausal Itching/Hives: Prefer non-sedating (Claritin, Zyrtec); avoid Benadryl long-term due to dementia risk. (28:06)
• Other Health Fads – Pass or Keep:
  • Eat kiwi with skin: Keep! (double the fiber, mood & gut boost) (33:54)
  • Freezing bread then toasting: Keep! (more resistant starch, better for gut) (34:30)
  • Lemon water for youth: Pass (overhyped) (35:22)
  • Fiber maxing: Keep! (most people deficient) (35:39)
  • Bone broth: Neutral; good, but not magic. (37:05)
  • Walking after meals: Keep!; "exercise snacks" (mini bursts) better than one long session. (37:53)
  • Green powders instead of veggies: Pass (36:41)

7. Practical Advice for Listeners

• If you do only one thing: Try "30, 30, 3" for a few days and get outside for a “sunny walk.” (32:27)
• Exercise "snacks" throughout the day are better for blood sugar than a single long session. (38:25)
• Gut, hormone, and immune issues are linked—overlap is normal, and fixing nutrition helps all. (39:04)
• Routine screenings: Don't ignore symptoms; get colonoscopies as recommended in midlife. (39:31)

Notable Quotes & Memorable Moments

• On diet mistakes:
  • “Your body knows if it doesn’t send you huge red flags... like when you’re in the wrong relationship.” (Dr. Amy Shah, 06:30)
• On gut changes:
  • “Estrogen has a huge effect on the microbiome.” (Dr. Amy Shah, 08:20)
• On easy supplement strategy:
  • “Supplements are like new shoes for a marathon—they can help, but nutrition is how you really train.” (Dr. Amy Shah, 10:50)
• On health fads:
  • "Eat kiwis with the skin on—keep. This is a way to get double the fiber." (Dr. Amy Shah, 33:54)
  • “Fiber needed a good PR moment.” (Dr. Amy Shah, 35:39)
• On exercise:
  • “Exercise snacks can be your friend—do 10 squats every 45 minutes.” (Dr. Amy Shah, 38:25)
• On the power of food:
  • “Nutrition is the base. When you start to fix that crosstalk—through food, supplements, sleep—you start to improve all of it.” (Dr. Amy Shah, 31:43)

Listener Q&A and Additional Medical Insights

With Dr. Mindy Goldman, OB-GYN & Chief Clinical Officer at MIDI Health (45:38+)

• How do you know you're in perimenopause?

  • Symptoms overlap with menopause: hot flashes, sleep changes, cycle changes (shortening, skipping periods), mood swings.
  • "There isn’t a single test; look at patterns over time.” (Dr. Mindy Goldman, 46:03)

• Can you start hormone therapy before menopause?

  • Yes—and it may help symptoms even before final period.
  • Individualized approaches are key, especially if bleeding is also an issue. (48:11)

• Hormone therapy and cancer history:

  • There are circumstances where breast cancer survivors can use hormones, with options for both hormonal and non-hormonal therapies.
  • “No one should feel like they need to suffer.” (Dr. Mindy Goldman, 50:00)

• Testosterone for women:

  • Not FDA-approved, but evidence shows it may help with libido in postmenopausal women. Data for other uses (energy, mood, muscle) is less established. (52:01)

• Postmenopausal women and hormone therapy:

  • “Don’t let anyone tell you, you just need to suffer... Hormones may not always need to be off the table.” (Dr. Mindy Goldman, 54:49)
