John M. Poothullil, MD, FRCP, practiced medicine as a pediatrician and allergist for more than
30 years, with 27 of those years in the state of Texas.

During his medical practice, John became interested in understanding the causes of and interconnections between hunger, satiation, and weight gain to diabetes.

Recognizing that this theory was illogical, he spent several years rethinking the biology
behind high blood sugar and developed the fatty acid burn theory as the real cause of diabetes.
He continued researching the linkage between obesity, diabetes and cancer, and developed
additional insights into the causes of childhood and adult cancer and possible treatments
involving low-carbohydrate diets to initiate starving of cancer cells by removing their main
source of energy – glucose from grains
