The Diary of a CEODr. Annette Bosworth: Why insulin fuels chronic disease
Through structured ketosis, glycogen depletion, and Dr. Boz blood ratios; Bosworth links brain fog to insulin trash and her sardine challenge
CHAPTERS
- 0:00 – 5:10
Sardine Challenge And The Case For Ketosis
Bosworth opens with her notorious ‘sardine challenge’ and frames ketosis as the key to fat loss, muscle preservation, reversal of some visible aging, and better brain performance. Steven introduces her as an insulin‑resistance specialist and sets up the central claim: excess insulin is a core driver of chronic disease, and sustained ketone production can transform health within a year.
- 5:10 – 19:40
What An Internist Sees: Chronic Disease, ‘Trash’, And Medicine 2.0
Bosworth explains internal medicine as long‑term puzzle‑solving for complex chronic illnesses, contrasting ‘Medicine 2.0’ symptom management with metabolic root‑cause reversal. She lays out her thesis that many subtle complaints—brain fog, midlife weight gain, joint pain—reflect accumulated cellular ‘trash’ from years of high insulin and missed ‘rules of being human’.
- 19:40 – 31:30
Insulin 101: How Late‑Night Eating Ages You Faster
Using Steven’s own eating pattern as an example, Bosworth illustrates how meal timing and composition spike insulin overnight, accelerating aging. She explains insulin’s core role in shuttling glucose and driving fat storage, and why late, carb‑heavy dinners keep insulin elevated well into the next day, even after sleep.
- 31:30 – 34:30
Hidden Insulin Resistance: Skin Tags, Hairless Toes, And Dirty Necks
Bosworth details physical signs of long‑standing insulin resistance that often precede diabetes. She describes how excess insulin alters the skin, hair growth, and fat distribution, and links these seemingly cosmetic issues to deeper metabolic and vascular damage.
- 34:30 – 44:30
Glucose vs Ketones: Draining Glycogen To Unlock Fat Burning
The discussion turns to energy substrates: glycogen, glucose, and ketones. Bosworth explains why many people never reach meaningful ketosis despite ‘doing low carb’ for several days, due to massive glycogen stores and entrenched insulin resistance—especially after pregnancies or years of overeating.
- 44:30 – 57:10
Why Ketones Feel Different: Brain Performance, Mood, And Recovery
Bosworth outlines why ketones subjectively feel so good: they burn cleaner, create fewer reactive byproducts, and feed the brain even when insulin signaling is impaired. She and Steven compare cognitive performance on keto vs high‑carb days, and she describes group interventions where people experience dramatic improvements within weeks.
- 57:10 – 1:10:20
Long‑Term Keto: Sustainability, Performance, And Aging
Addressing concerns that keto isn’t sustainable or harms performance, Bosworth shares data on military personnel whose power increased after prolonged keto adaptation and her own decade‑long experience. She maintains that once people feel the difference, they naturally avoid high‑sugar episodes that bring pain, brain fog, and mood swings back.
- 1:10:20 – 1:21:40
Ketones And Cognition: Dementia, Down Syndrome, And ‘Type 3 Diabetes’
The conversation dives into dementia and Alzheimer’s, which Bosworth and Steven both frame as ‘type 3 diabetes’—a state where brain glucose utilization fails while ketone utilization remains. Bosworth shares a striking Down syndrome case where strict keto improved both weight and cognitive function, potentially reversing an Alzheimer’s diagnosis.
- 1:21:40 – 1:31:00
Measuring Metabolism: Glucose, Ketones, And The Dr. Boz Ratio
Bosworth demonstrates how to use a dual glucose/ketone meter, interprets Steven’s and her own numbers, and introduces the Dr. Boz ratio as a practical marker for fat burning and therapeutic ketosis. A team member’s low ketones illustrate how common it is to be entirely glucose‑dependent.
- 1:31:00 – 1:44:00
Keto Continuum: From Carb Cutting To Multi‑Day Fasting
Bosworth walks through her 12‑step Keto Continuum, a structured roadmap from standard eating to advanced fasting. She describes how each phase builds metabolic flexibility, lowers insulin, and increases the frequency and depth of ketosis, especially for those with long‑standing insulin resistance or serious illness.
- 1:44:00 – 1:54:00
Sex Differences, Hormones, And Menstrual Health On Keto
They discuss how men and women differ in fat loss and metabolic adaptation, and how insulin resistance affects sex hormones. Bosworth pushes back on the idea that keto wrecks women’s hormones, arguing instead that high insulin is already wrecking them and keto can restore communication between hormones.
- 1:54:00 – 2:10:00
Sardines, Fiber Controversy, And The 100‑Day Sardine Experiment
Bosworth explains why she uses sardines as a therapeutic food: simple, cheap, nutrient‑dense, and nearly carb‑free. She recounts a patient, Jane, who did 100 days of only sardines, significantly improving weight, vitamin D, and emotional relationship with food. She then challenges mainstream views on fiber and the microbiome, arguing that butyrate from ketones can substitute for fiber‑driven butyrate.
- 2:10:00 – 2:26:00
Supplements: Vitamin D, Magnesium, Creatine, Methylene Blue, And Exogenous Ketones
They move into adjunctive tools. Bosworth highlights vitamin D as a hormone trapped in fat when insulin is high, magnesium as a universal cofactor, creatine as a brain and jet‑lag aid, and methylene blue as an old drug that enhances mitochondrial function. They also discuss exogenous ketones as a bridge back into ketosis, especially around chemo.
- 2:26:00 – 2:35:00
Keto, GLP‑1 Drugs, And Natural Appetite Suppression
With the rise of Ozempic and related GLP‑1 agonists, Bosworth compares pharmacologic appetite suppression to keto‑induced hormonal changes. She cautions that powerful drugs used for vanity weight loss resemble using chemotherapy to remove leg hair—overkill with potential unintended consequences—when natural GLP‑1 boosting via ketones and butyrate is available.
- 2:35:00 – 2:48:00
Motivation, Purpose, And The Psychology Of Staying Keto
Recognizing that information alone doesn’t guarantee adherence, they discuss motivation, identity, and deep ‘why’s. Bosworth emphasizes that people usually start keto after a health crisis, but long‑term success depends on addressing emotional wounds and core insecurities, as Jane did through her sardine commitment.
- 2:48:00 – 3:12:00
Political Prosecution, Felony Charges, And Rebuilding A Life
In a stark, personal section, Bosworth recounts leaving corporate medicine, treating poor and Native American patients more aggressively than the state liked, and being investigated for Medicaid fraud over IV iron treatment she paid for herself. After that failed, political adversaries targeted her during a US Senate run, ultimately convicting her on twelve felonies over petition witnessing technicalities, sentencing her to 24 years before suspending the sentence.
- 3:12:00
Faith, Daily Practice, And Closing Reflections
In the closing segment, Bosworth answers a question about finding inner peace when emotionally triggered. She shares her daily devotional practice that grounds her in faith, explains how historical and scriptural guidance helps her navigate adversity, and Steven recaps her work and resources for viewers wanting to go deeper.
