46 research-tied claims examined: 1 contradicted 2 overstated 7 context 27 supported 3 corroborated online 6 unverified
"where 99% of patients will never get normal metabolic control after their initial diagnosis." (said at 0:15:40)
No published record matching the claim that 99% of patients diagnosed with type 1 diabetes never achieve normal metabolic control after diagnosis was located; this does not prove the claim false.
"And they're fourfold higher more publications in just pharmacological and technological advancements than there is in nutrition." (said at 0:30:10)
No published record matching the claim that there are four times (or fourfold) more publications on pharmacological and technological diabetes advancements than on nutrition-based diabetes interventions was located; this does not prove the claim false.
"And the American Diabetes Association in 1970s for the first time came out with their first nutritional guidance. And essentially what they did is they modeled the US dietary guidelines that first came out in the 1970s." (said at 0:29:40)
No published record matching the claim that the American Diabetes Association issued its first nutritional guidance in the 1970s modeled on the inaugural U.S. Dietary Guidelines was located; this does not prove the claim false.
"what we found is that when athletes were either on a ketogenic diet or on a high-carb diet doing 6 by 800-meter sprints or a max-effort 1-mile time trial—so the fastest you can run for 4 to 6 minutes in duration—we found that the ketogenic diet did not produce any deterioration in physical performance in these high-intensity athletic endeavors." (said at 0:58:45)
No published record matching the specific study described (evaluating 6x800m sprints and a 1-mile time trial following 4 or more weeks of a ketogenic diet versus a high-carbohydrate diet) was located; this does not prove the claim false. Published randomized trials by the speaker and colleagues have evaluated acute meal-timing effects on 5k and 10k running, but peer-reviewed findings for this specific multi-week sprint and 1-mile interval intervention protocol have not appeared in the indexed literature.
"And what we found is that when we looked at these 160 different studies, when carbohydrates reliably improved performance, David, what was happening is that the placebo group of those studies, 88% of the time, the placebo or control group was seeing a precipitous drop in blood glucose levels." (said at 1:06:45)
No published record matching a review of over 160 sports nutrition studies in Endocrine Reviews reporting that placebo/control groups experienced a precipitous drop in blood glucose levels 88% of the time when carbohydrate feeding improved performance was located; this does not prove the claim false.
"in the blood, not just glucose, but also ketones and lactate, all fuels for the brain, the high carbohydrate athletes and the ketogenic athletes had the same amount of brain energy metabolites circulating in the blood." (said at 1:03:03)
No published record matching the claim that total circulating brain energy metabolites (glucose, ketones, and lactate combined) are equivalent between high-carbohydrate adapted and ketogenic adapted endurance athletes was located; this does not prove the claim false.
