The Sugar Doctor: The Simple Diet That Prevents 80% of Disease!

TL;DR

Dr. Andrew Kutanik, a research scientist with type 1 diabetes and a history of obesity, argues that glucose control — measured by HbA1c — is the single most powerful predictor of chronic disease and that reducing carbohydrates, particularly through a well-formulated ketogenic diet, can normalize glucose, reduce insulin requirements by over 40%, and improve cardiovascular health even when LDL doubl

Key insights

• HbA1c (average blood glucose over 2–3 months) is the strongest predictor of future cardiovascular disease, eye/kidney disease, and mortality.
• Over 68% of Americans are obese; 93% have some form of metabolic derangement; over 20% of children have obesity (quadrupled in 30 years).
• Ketogenic diets have been used therapeutically for type 1 and type 2 diabetes since at least 1796 (Dr. John Rollo) and for epilepsy since 1921 (Mayo Clinic).
