Ivor Cummins, a chemical engineer, has reshaped the discussions around the important risk factors that result in coronary artery disease and cancers. His insightful evaluation of the relative importance of LDL cholesterol, inflammation markers and insulin resistance has refined the understanding of a low-carbohydrate lifestyle. He and Jeffry Gerber, (“Denver’s Diet Doctor”) reintroduced the work of the late pathologist Joseph Kraft who discovered a new classification of insulin resistance. This classification is now a gold standard in evaluating pancreatic function in disease and health. Kraft was instrumental in educating the general public and healthcare professionals about the nuances of a low-carbohydrate lifestyle.
