Every claim in Glucose Spike Check, checked
This is the book's verification ledger, published in full. Every factual claim was extracted from the manuscript and handed to an independent blind checker — one claim, its cited source, nothing else. High-stakes claims (doses, safety, real diseases, trial numbers) were checked by three checkers who had to agree. Every checker first had to confirm the cited source actually exists.
62claims checked
51verified first pass
11flagged & corrected
The honest part: 11 claims did not survive first contact with their own sources — the checkers flagged them as misstated or unsupported. Each one was corrected in the text and re-verified by a fresh blind panel before the book was published. The table below shows the first-pass verdicts, because that's the honest number: what the machine got wrong before checking, not after.
| id | claim as written | stakes | first-pass verdict |
|---|---|---|---|
| C1 | Front and back matter state a registered, practising, AHPRA-registered Australian doctor read the whole book and checked every factual and clinical claim against current medical guidance before publication, catching overstatements and a citation that did not hold up. | high | unsupported → corrected |
| C2 | States that neither incumbent author is free of a financial stake in the answer she is selling, framed across Ch1 and the closing chapter. | high | verified |

| C10 | Casey Means is "the co-founder of Levels, a company that sells continuous glucose monitors and an accompanying app," the exact product her book's central recommendation points toward. | high | verified |
| C11 | Levels "charges you roughly $500 up front and $250 a month. | high | misstated → corrected |
| C12 | In both books, the single biggest thing you're told to do also happens to be the thing the author's own company sells you. | high | verified |
| C13 | *Glucose Revolution*, published in 2022, followed by *The Glucose Goddess Method* in 2023. | low | verified |
| C14 | *Good Energy*, published in 2024 by Dr. Casey Means with her brother Calley Means. | low | verified |
| C15 | Blood glucose "is supposed to go up after you eat" — eating carbohydrate, protein, or a mixed meal makes blood glucose rise; that is digestion working, not a malfunction. | high | misstated → corrected |
| C16 | Insulin is the hormone the pancreas releases in response to rising blood glucose to bring it back to baseline (into muscle, liver, fat), released as a fast first-phase burst then a steadier second wave; smooth and self-limiting in a healthy pancreas. | high | verified |
| C17 | A home CGM "has no built-in way to tell" a healthy pancreatic response from impaired glucose tolerance; the difference is not visible from the graph alone. | high | verified |
| C18 | Diabetic "time in range" targets were developed for people with diagnosed (usually insulin-treated) diabetes and calibrated to that population's risk; there is no equivalent established consensus target range for a person without diabetes. | high | verified |
| C19 | People without diabetes show a recognizable shared post-meal shape — glucose rises, stays elevated for roughly one to two hours depending on the meal, then returns to baseline. | high | unsupported → corrected |
| C20 | Whether glucose variability itself predicts long-term health in non-diabetic people is "a real, live research question" that "hasn't been settled either way"; current evidence is "too thin" to say it predicts future disease risk. | high | verified |
| C21 | At least one endocrinologist has pushed back on the AGE "cooks you from the inside" causation-vs-correlation problem, noting the AGE-and-aging link "has been debated for years. | high | verified |
| C22 | A well-known 2003 cinnamon-and-glucose study" now carries a "formal expression of concern attached to it by the journal that ran it" — explicitly not a retraction. | high | verified |
| C23 | Meal-sequencing (vegetables first, carbs last) has a real, replicated evidence base in controlled test-meal studies, but at least one dietitian objected publicly that in a real mixed dish "food doesn't work that way. | high | verified |
| C24 | A meaningful share of the foundational research on vinegar and glucose response was conducted in people who already had diabetes or impaired glucose tolerance," not the healthy readership the advice targets. | high | verified |
| C25 | A wellness app watches glucose and, when it rises past an internal threshold, sends a push notification framing a normal physiological event as a problem, sitting next to the product that "fixes" it. | low | misstated → corrected |
| C26 | A CGM app "can show you a line going up after lunch. It cannot show you your risk of type 2 diabetes in 2046" — a short-term graph does not support a long-term metabolic verdict. | high | verified |
| C27 | At least one published review says a bestselling glucose book does not mention class, poverty, or race and caters to "a very niche population" with money and time. | low | misstated → corrected |
| C28 | There is real, published concern" that repeat, obsessive glucose-checking (turning food into something you are evaluated on) "has the potential to contribute to disordered-eating-adjacent anxiety in some users. | high | verified |
| C29 | Reactive (postprandial) hypoglycaemia is "a recognised, investigable clinical phenomenon," happening when post-meal insulin release overshoots relative to the glucose load. | high | verified |
| C30 | A home CGM dip "is not a diagnosis"; confirming reactive hypoglycaemia means correlating genuine hypoglycaemic readings with symptoms and ruling out other causes, sometimes via a supervised clinical test. | high | verified |
| C31 | Prediabetes and type 2 diabetes are common, "frequently silent for years, and a meaningful number of cases in Australia go undiagnosed at any given time." (No numeric figure stated in prose.) | high | verified |
| C32 | Diagnosis of prediabetes and type 2 diabetes in Australia is made using fasting plasma glucose, HbA1c, or an oral glucose tolerance test (OGTT), interpreted against validated thresholds — not a consumer CGM. (No cutoff numbers stated in prose.) | high | verified |
| C33 | Both an underactive thyroid and an overactive one can produce fatigue, weight change, and energy swings that overlap heavily with what people attribute to glucose spikes. | high | verified |
| C34 | PCOS "can present with fatigue, weight changes, and metabolic symptoms" a reader might misattribute to glucose spikes, and is a genuine differential worth ruling out. | high | verified |
| C35 | Red-flag checklist warranting a GP visit: unexplained weight loss; excessive thirst or urination; recurrent fainting or severe shakiness and sweating after meals; family history of diabetes plus any of these; and fatigue that is not improving. | high | verified |
| C36 | Muscle is the single biggest reservoir for glucose disposal," and moving shortly after a meal (e.g. a short walk) is one of the most consistently observed levers for blunting a post-meal rise and supporting glycaemic health. | high | verified |
| C37 | Adequate sleep is linked to metabolic health; short or poor-quality sleep is associated with worse insulin sensitivity and appetite regulation in the broader literature. | high | verified |
| C38 | Eating refined carbohydrate alongside fibre and protein, rather than alone, "has a real evidence base behind it for general glycaemic and metabolic outcomes. | high | verified |
| C39 | Minimising free sugars and refined starch is supported for general metabolic and overall health and is in the Australian Dietary Guidelines. | high | verified |
| C40 | Body weight and metabolic health are linked strongly and consistently across the literature," independent of any glucose-monitoring device. | high | verified |
| C41 | Specific rituals — a fixed food order every meal, a capful of vinegar at a precise interval — "sit on much thinner ground," often studied in small samples or in people with impaired glucose tolerance rather than the healthy readership. | high | verified |
| C42 | Time in range" was built for and validated in diagnosed diabetes; there is currently no equivalent validated "aim for this range" target for healthy people without diabetes. | high | verified |
| C43 | Whether glucose variability itself predicts anything meaningful about long-term health in people without diabetes "is a genuinely open research question right now. | high | verified |
| C44 | Johns Hopkins Bloomberg School of Public Health "published directly on the question of whether glucose monitoring is useful if you don't have diabetes," under the title "Is Glucose Monitoring Useful for Non-Diabetics? | low | verified |
