WHAT IT’S REALLY ABOUT

Measure cortisol first to rebalance hormones, energy, mood, and fertility

  1. Hormones are chemical “messengers” that govern homeostasis, and imbalance often shows up as fatigue, weight gain, mood issues, acne, fertility problems, or disrupted cycles rather than an obvious “hormone problem.”
  2. Chronic stress is framed as the #1 modern driver of hormonal dysfunction, with cortisol positioned as the “great unifier” that can disrupt insulin, thyroid, progesterone, and testosterone—so measurement and stress-response tracking are prioritized.
  3. Metabolic dysfunction is explained through insulin resistance (insulin as the “bouncer”), emphasizing that elevated insulin often precedes abnormal glucose by years and can be improved rapidly via food, movement, and monitoring.
  4. Sex hormones differ mainly by degree (not presence), with key life-stage shifts (puberty, 20s peak, 30s early fertility/androgen changes, 40s perimenopause; gradual andropause in men) and special attention to thyroid autoimmunity in women.
  5. The conversation critiques routine birth-control prescribing for non-contraceptive issues (acne/painful periods) without full informed consent, discusses potential downstream effects, and offers alternatives like lifestyle changes, cycle tracking, and preference for copper IUDs with proper pain control during insertion.

IDEAS WORTH REMEMBERING

5 ideas

Start with cortisol if you feel “off” and don’t know why.

Szal calls cortisol the “great unifier” because high or low cortisol can cascade into insulin issues, lowered progesterone, and reduced testosterone; she recommends measuring cortisol (and/or tracking HRV) before guessing at willpower or mindset failures.

Aim for “optimal,” not merely “normal,” lab ranges.

She distinguishes optimal targets (e.g., morning cortisol ~10–15; afternoon ~5–10) from population “normal,” arguing that feeling well often requires treating toward a Goldilocks zone rather than average values.

Insulin is an early-warning signal—and can improve quickly.

Insulin resistance is described as cells becoming “numb” to insulin, driving fat storage and elevated blood sugar; she notes insulin can shift within days via food/exercise and often changes 7–14 years before glucose abnormalities appear.

Many “personal” struggles can be biological signals, not moral failings.

Fatigue, low motivation, brain fog, and weight gain are framed as potential hormone/stress/thyroid issues that deserve measurement and root-cause work before self-blame—while still integrating mindset and meaning.

Simple evening ‘bookends’ can downshift your stress response.

Instead of defaulting to wine/doom TV, they propose an à la carte menu: short meditation/breathwork, horizon-gazing to relax eye muscles, gentle yoga (even 5 minutes), a short walk (also helps glucose), meaningful reading, cooking as ritual, and a quick partner “vibe check.”

WORDS WORTH SAVING

5 quotes

So with all hormones, I can't think of a single exception, you want it to be in this Goldilocks zone of not too high and not too low.

— Dr. Sara Szal

You know, what happens for a lot of folks is that they feel tired... and they assume that it's some sort of moral failing... And I would say let's start with your biology before we go to the place of moral failing.

— Dr. Sara Szal

When it comes to a hormone like insulin, you can change it with your food and exercise in three days.

— Dr. Sara Szal

Start with cortisol. There's a few reasons for that. Cortisol is the great unifier because it's involved in all of these other systems.

— Dr. Sara Szal

This idea that pain is a normal part of being female and cycling is a myth that we totally have to bust because it's not normal for your periods to hurt.

— Dr. Sara Szal
