PCOS, Insulin Resistance & the Myth of the Willpower Diet

The most common mistake in PCOS nutrition isn't what you're eating — it's the framework you're using to think about food.

Polycystic ovary syndrome affects 1 in 10 women of reproductive age, yet most receive dietary advice that addresses symptoms rather than the underlying hormonal architecture. The standard low-calorie prescription misses the point entirely.

Clinical work with PCOS clients begins with a fasting insulin panel, not a food diary. Once we understand how aggressively the body is converting glucose to fat storage, we can design a carbohydrate distribution strategy that works with — not against — the endocrine system.

This means strategic carbohydrate timing, specific fiber targets that slow gastric emptying, and micronutrient protocols addressing the documented deficiencies common in PCOS: inositol, vitamin D, magnesium, and zinc.

“Insulin is the conductor of this orchestra. Every food choice is a note. We are not restricting the music — we are rewriting the score.”

“After three years of being told to "just lose weight," Dr. Holloway looked at my bloodwork and said: your cortisol is driving this, not your portion sizes. That single reframe changed everything. My cycles are regular for the first time since I was seventeen.”

Gut Integrity

IBS Is Not a Diagnosis. It's a Description of a Problem We Haven't Fully Named Yet.

The low-FODMAP protocol is a diagnostic tool, not a permanent prescription. Most practitioners use it as an endpoint. I use it as a starting line.

Irritable bowel syndrome is the diagnostic code assigned when conventional gastroenterology has ruled out the diseases it knows how to test for. The patient is left with a label that describes their suffering but offers no mechanistic explanation.

A thorough functional nutrition assessment begins with a comprehensive stool analysis, food sensitivity panel, and detailed symptom mapping. The low-FODMAP elimination is then used precisely: as a 6-8 week diagnostic window, not a lifetime sentence.

Reintroduction is where the real clinical work happens. Each food group returns individually, symptoms are tracked with precision, and we begin to understand the specific microbial and permeability signatures driving that individual's reactivity.

“The gut microbiome is an ecosystem. You cannot restore an ecosystem by removing everything from it. You restore it by understanding what belongs there.”

“I had been on a near-elimination diet for two years, terrified of everything. The reintroduction process was methodical and slow, and for the first time I understood WHY certain foods affected me. I now eat 80% of what I avoided. That's not a small thing.”

Performance Nutrition

The Athlete's Gut: Why Your Race-Day Nutrition Is Failing Before Mile Six

Endurance athletes are the most disciplined eaters I work with, and some of the most chronically underfueled. Training load and caloric intake are not having the same conversation.

The most common presentation in endurance athlete clients is relative energy deficiency in sport (RED-S) — not disordered eating, but systematic underfueling driven by training periodization that doesn't account for actual metabolic demand.

A complete sports nutrition assessment includes resting metabolic rate testing, training load analysis, gut tolerance mapping, and a targeted micronutrient panel. Iron, ferritin, vitamin D, and B12 are the most frequent deficits, and their impact on VO2 max and recovery is clinically significant.

Race nutrition protocols are built from the gut outward: we establish tolerance windows, practice the protocol in training, and troubleshoot GI distress with the same rigor applied to interval pacing.

“You cannot out-train a 600-calorie deficit in the third week of a build block. The body will find a way to conserve. That's not weakness. That's biology.”

“I'd been bonking at mile 18 of every marathon for three years. Turned out my iron was at the bottom of normal, my carbohydrate intake on long runs was 40% below what the science supports, and I was chronically dehydrated. Fixed all three. Ran a BQ in my next race.”

Postpartum Recovery

The Fourth Trimester Nutrition Gap No One Is Talking About

Pregnancy depletes. Labor depletes further. Breastfeeding continues the draw. And yet the postpartum nutrition conversation in most clinical settings begins and ends with "eat well."

Postpartum iron deficiency affects up to 50% of new mothers and is significantly underdiagnosed. The symptoms — fatigue, cognitive fog, low mood, reduced milk supply — overlap with expected postpartum experience, making clinical detection challenging.

A comprehensive postpartum nutrition assessment includes a full iron panel (serum ferritin, transferrin saturation, hemoglobin), vitamin D, B12, folate, omega-3 fatty acids, and thyroid function. These are the biological substrates of recovery, and most postpartum care does not test for them.

Meal planning in the postpartum period must account for one-handed eating, time constraints, breastfeeding caloric demands, and the specific micronutrient return needed to restore the body's depleted reserves. It requires precision, not inspiration.

“A new mother's body is doing the most nutritionally demanding work of her life in the context of sleep deprivation, hormonal upheaval, and systemic depletion. She deserves a prescription, not a pamphlet.”

“My OB told me my iron was "fine." Dr. Holloway looked at the same numbers and said my ferritin was critically low for a breastfeeding mother. Six weeks of her protocol and I felt like myself again — genuinely myself, not the diminished version I'd accepted as the new normal.”
