Katie Keen, functional nutrition expert and former law enforcement officer, shares her personal healing journey from chronic inflammation, PCOS, and mysterious weight gain that doctors dismissed as 'all in her head.' After functional medicine transformed her health, she became a specialist helping women address root causes of fertility challenges through personalized nutrition protocols.
Functional nutrition for PCOS, hypothyroidism, and fertility challenges
Key Insights
Actionable Advice
Katie Keen shares her frustrating experience of gaining and losing weight repeatedly while experiencing fatigue, insomnia, and menstrual problems. Despite multiple doctor visits, her OBGYN dismissed her symptoms as psychological and referred her to therapy, even though she was suffering from undiagnosed PCOS, hypothyroidism, and severe inflammation.
After Rosanne recommended a functional medicine doctor, Katie's life changed dramatically. In just 1.5 years, she lost 50 pounds and healed multiple conditions including leaky gut, non-alcoholic fatty liver, and chronic inflammation through targeted nutritional protocols and supplements.
Katie explains how functional nutrition differs from generic dietary advice by addressing root causes through personalized protocols. Rather than telling someone to 'go paleo,' it involves deep-diving into individual health history, lab work, and specific imbalances to create tailored solutions.
Both experts discuss how standard medical lab ranges are based on sick populations and geographic averages, not optimal health. This explains why women can feel terrible while being told their bloodwork is 'normal' - functional practitioners read the same labs through an optimal wellness lens.
Katie emphasizes that everyone consuming modern food has gut health issues, whether they recognize symptoms or not. She addresses how people normalize digestive problems like acid reflux and constipation when these are actually signs of imbalance affecting overall health and fertility.
The conversation covers often-overlooked environmental factors affecting fertility, including toxic particles in household dust from cleaning products and personal care items. Katie teaches practical strategies like wet dusting and recommends an 80/20 approach to toxin reduction to avoid overwhelming perfectionism.
Both women discuss how functional nutrition creates ripple effects throughout families. Rosanne shares how her son Asher now reads food labels and makes educated choices, while Katie explains how her work teaches families to create healthier environments for current and future generations.
“functional nutrition is actually a holistic and personalized approach where you're deep diving into the root causes behind what's causing the imbalances in somebody's body and then fixing those imbalances by different protocols or like nutritional tailored nutritional plans and lifestyle strategies”
— Katie Keen▶ 10:38
Functional nutrition is a personalized approach that identifies root causes of health imbalances through detailed health history and testing, then creates tailored nutrition and lifestyle protocols. Unlike generic advice to 'eat paleo' or 'go healthy,' it addresses your specific deficiencies and sensitivities.
“I specialize in PCOS, hypothyroidism, Hashimoto's, and with all of that comes the insulin resistance, the inflammation, and the GI issues”
— Katie Keen▶ 18:13
Yes, functional nutrition can address PCOS by targeting blood sugar balance, insulin resistance, and inflammation - the root causes. Katie Keen specializes in PCOS and saw her own symptoms resolve along with 50 pounds of weight loss through functional protocols.
“this may be in range for what your doctor learned in medical school, but functionally it's not because it's not optimal for your body”
— Katie Keen▶ 35:08
Standard lab ranges are based on sick populations and vary by age and location, not optimal health. Functional practitioners read the same labs through an 'optimal health' lens, identifying issues that appear 'normal' but aren't ideal for fertility and wellness.
“every single day when I got on the scale, every single day of the week, my weight was going down. Because my inflammation was just dropping and dropping and dropping”
— Katie Keen▶ 8:35
Results can begin within days to weeks. Katie Keen saw daily weight loss as inflammation dropped, while Rosanne Austin noticed changes in 11 days with her personalized protocol. Sleep, energy, and digestive issues often improve first.
“a lot of the protocols that people will go on in the beginning can be temporary things. Like at first, when I had to cut out gluten, and dairy, and eggs, and sugar, and alcohol, and all the things, that was temporary while I was fixing my gut”
— Katie Keen▶ 12:11
Not permanently. Initial elimination phases are temporary while healing occurs. Katie Keen reintroduced most foods after 1.5 years, only avoiding gluten long-term because it triggered inflammation. The goal is strategic, not restrictive.
“there are so many toxins from your air in your house, from the cleaners that you use, from your skin, if you're using toxic chemicals on your skin, your skin sheds, those dust particles are just sitting toxins in your house and you're breathing that every day”
— Katie Keen▶ 38:28
Dust particles containing toxins from cleaning products, personal care products, and air pollutants accumulate in homes. Katie Keen recommends 'wet dusting' after dry dusting to remove these particles you're breathing daily.
Katie Keen's step-by-step approach to addressing fertility challenges through personalized nutrition protocols
Complete comprehensive health assessment
Work with a functional nutrition expert to review your entire health history, current symptoms, and fertility goals through an in-depth consultation
Get functional lab analysis
Have existing lab work read through a functional lens for optimal ranges, or order new testing if needed to identify deficiencies and imbalances
Address gut health first
Begin with gut healing protocols even if you don't have obvious digestive symptoms, as gut health affects all other body systems
Follow personalized nutrition protocol
Implement a tailored eating plan based on your specific health history, lab results, and identified sensitivities or deficiencies
Reduce household toxin exposure
Learn about and gradually eliminate or replace toxic cleaning products, personal care items, and implement practices like wet dusting
Monitor and adjust
Work with your practitioner to track progress and adjust protocols as your body heals and needs change over time
Traditional medicine often dismisses women's health symptoms as psychological, even when serious conditions are present
Katie Keen went to her OBGYN multiple times with weight gain, fatigue, and menstrual problems. After blood tests showed 'normal' results, the doctor told her 'it's all in your head' and gave her a therapist's card, despite Katie having undiagnosed PCOS, insulin resistance, hypothyroidism, leaky gut, and severe inflammation.
Functional nutrition goes beyond general dietary advice to address root causes through personalized protocols based on individual health history and testing
Katie Keen explains functional nutrition as 'deep diving into the root causes behind what's causing the imbalances in somebody's body and then fixing those imbalances by different protocols or tailored nutritional plans and lifestyle strategies' - not just telling someone to 'go paleo' or 'eat healthy.'
Nutritional needs change over time, making ongoing assessment crucial rather than a one-time fix
Rosanne Austin discovered through testing that her food sensitivities in 2025 were completely different from 2022, emphasizing that 'this is a lifestyle change' and 'you're not going to do this for three days and check the box.'
Inflammation reduction can produce rapid, visible results when the right protocol is followed
Katie Keen lost 50 pounds in 1.5 years after her functional medicine doctor addressed her leaky gut, non-alcoholic fatty liver, and severe inflammation. She notes 'every single day when I got on the scale, my weight was going down because my inflammation was just dropping and dropping.'
Standard lab ranges are based on sick populations and may not reflect optimal health for fertility
Katie Keen explains that when doctors say 'everything looked fine,' functional practitioners can read the same labs differently: 'this may be in range for what your doctor learned in medical school, but functionally it's not because it's not optimal for your body.' She also reveals ranges vary by age and geographic location.
Gut health issues are universal in modern life and affect fertility even when symptoms seem 'normal'
Katie Keen states 'every single person on earth who consumes food period has something going on in their gut' and notes that people accept acid reflux, bloating, and constipation as normal when 'that's not normal.' She emphasizes addressing gut health whether you think there's a problem or not.
Functional nutrition benefits extend beyond the individual to create healthier families and future generations
Katie Keen explains her work is 'for your family's life' as clients learn 'how to feed your kids, how to feed your family, how to remove toxins from your house.' Rosanne Austin shares her 8-year-old son Asher now reads labels and makes educated food choices, saying 'that wife of his better have gone through Katie's program.'
Toxin exposure in the home environment directly impacts fertility and can be reduced through education and strategic changes
Katie Keen teaches about 'wet dusting' to remove toxic particles from air and explains how 'toxins from your air in your house, from the cleaners that you use, from your skin' create dust particles 'you're breathing every day.' She emphasizes an 80/20 approach: 'as long as you're cutting out as many things as you can, not even fully nontoxic, just lowering your toxins, you're winning.'

“She said at that time, it's all in your head. She gave me a card to the therapist in the building next door and told me that I needed to go talk to somebody.”
“I'm not kidding when I say I've never had results like this before. Every single day when I got on the scale, every single day of the week, my weight was going down. Because my inflammation was just dropping and dropping and dropping.”

Key Shifts
Conventional 'normal' lab ranges are based on sick populations and miss optimal health markers needed for fertility
Dr. Watkins explains TSH reference range is 0.45-4.5, but someone at 0.057 is 'one bad stressful situation from bottoming out' despite being technically normal. She's seen patients told their thyroid is normal when only TSH was tested, missing Hashimoto's detected through antibody testing.
Hashimoto's thyroiditis is largely environmental, driven by gluten inflammation, pesticides, and gut permeability
Dr. Watkins notes strong scientific evidence linking gluten to thyroid inflammation, plus environmental toxins from food, water, cleaning products, and occupational exposures. She sees genetic predisposition triggered by environmental burden in her practice.
Ninety percent of medical school curriculum focuses on pharmacology, while 80% of medical schools don't require a single nutrition class for doctors to graduate
Calley Means, former pharma lobbyist, reveals that Stanford Medical School and Harvard Medical School are among the institutions that don't require nutrition education, despite food being the primary driver of metabolic dysfunction affecting fertility.
PCOS and fertility issues are fundamentally connected to insulin resistance and metabolic dysfunction, which can be reversed through dietary interventions
Calley's sister Casey, a Stanford-trained surgeon, discovered that patients with fertility issues, depression, diabetes, and high cholesterol all shared root metabolic dysfunction that could be addressed through food and exercise interventions rather than separate medications for each condition.
