✓Well SupportedDiabetic patients consuming high amounts of honey (up to 180+ grams/day) in a study lost weight and became more insulin sensitive, despite an increase in hemoglobin A1c.✓Well SupportedPure fructose or processed sugars like high-fructose corn syrup should not be conflated with whole-food carbohydrate sources such as fruit or honey.✓Well SupportedSleep quality improves for most people when carbohydrates are included in their diet, and sleep disturbance is common on strictly carnivorous diets.✕Not SupportedThe argument that most insulin resistance is induced by hyperinsulinemia from eating more carbohydrates is false and lacks good evidence in free-living humans.

✓Well Supported

It is virtually impossible to develop insulin-induced insulin resistance outside of a laboratory setting with continuous insulin infusion.

✓Well SupportedInsulin signaling stimulated by carbohydrate intake is essential at the kidney level for electrolyte resorption.

✓Well SupportedA moderate intake of carbohydrates (50-100 grams per day) is likely acceptable for individuals with diabetes.

✓Well SupportedIncluding carbohydrates in the diet can improve performance, sleep, mood, libido, and muscle maintenance/gains for metabolically healthy individuals.

◐Partially SupportedInsulin signaling stimulated by carbohydrate intake improves antioxidant status by linking to glutathione.

◐Partially SupportedInsulin signaling, stimulated by carbohydrate intake, is anti-catabolic and helps preserve muscle tissue.

◐Partially SupportedFor metabolically healthy, highly active men, 200-300 grams of carbohydrates per day may be appropriate.

◐Partially SupportedCarbohydrates are valuable for pre-diabetic, obese, or weight-losing individuals, scaled to activity levels.

✕Not SupportedBlood glucose spikes from carbohydrates do not cause obesity or diabetes.

◐Partially SupportedThe Walter Kempner rice diet, consisting of white rice and sugar, was used to cure diabetics, induce weight loss, and improve insulin sensitivity.
