Ninety-nine percent of patients diagnosed with type 1 diabetes never achieve normal metabolic control after diagnosis.

"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.

William Sansum was the first person in the United States to chemically extract and administer insulin to save a patient's life.

"So, William Sansum, where I used to work, was actually the first person in the United States of America to both chemically extract and also administer insulin to save the life of a patient in the United States of America." (said at 0:28:40)

No published record matching the claim that William Sansum was the first person in the United States to chemically extract and administer insulin to save a patient's life was located; this does not prove the claim false.

In 1925, William Sansum published a paper in JAMA advocating that patients receiving insulin should have enhanced dietary freedom, without support from randomized controlled trials.

"William Sansum the founder of the institute I worked at also published a paper in JAMA in 1925 where he then argued that patients with the ability to administer insulin should now have enhanced freedom in their dietary choices. He made this recommendation in the absence of any serious, rigorous, randomized control trial evidence." (said at 0:29:00)

No published record matching William Sansum's 1925 JAMA paper on enhanced dietary freedom for insulin-treated patients was located; this does not prove the claim false.

The American Diabetes Association issued its first nutritional guidance in the 1970s, modeling it on the inaugural U.S. Dietary Guidelines.

"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)

There are four times more published studies on pharmacological and technological diabetes advancements than on nutrition-based diabetes interventions.

"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.

In 1962, MIT studied 1,3-butanediol for aerospace transport as a shelf-stable, high-caloric-density nutrient.

"So, then in 1962, MIT actually studied 1,3-butanediol, which is in products like Ketone-IQ, for aerospace transport. Why were they interested in that? Because it was a very shelf-stable molecule that could go into outer space with high caloric density." (said at 0:50:20)

High-intensity athletic performance (6x800m sprints and 1-mile time trials above 85% VO2 max) did not deteriorate after 4 or more weeks on a ketogenic diet compared to a high-carbohydrate diet.

"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.

Total circulating brain energy metabolites in the blood—including glucose, ketones, and lactate—are equivalent between high-carbohydrate adapted and ketogenic adapted endurance athletes.

"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)

In a review of over 160 sports nutrition studies published in Endocrine Reviews, when carbohydrate feeding reliably improved performance, the placebo/control group experienced a precipitous drop in blood glucose levels 88% of the time.

"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."
