Robert H. Lustig

Robert H. Lustig (born 1957) is an American pediatric endocrinologist. He is professor emeritus of pediatrics in the division of endocrinology at the University of California, San Francisco (UCSF), where he specialized in neuroendocrinology and childhood obesity. He is also director of UCSF's WATCH program (Weight Assessment for Teen and Child Health), and president and co-founder of the non-profit Institute for Responsible Nutrition.

Lustig came to public attention in 2009 when one of his medical lectures, "Sugar: The Bitter Truth", was aired. He is the editor of Obesity Before Birth: Maternal and Prenatal Influences on the Offspring (2010), and author of Fat Chance: Beating the Odds against Sugar, Processed Food, Obesity, and Disease (2013).

Biography Lustig grew up in Brooklyn, New York, and attended Stuyvesant High School in Manhattan. He obtained a bachelor's degree from the Massachusetts Institute of Technology in 1976 and a M.D. from Cornell University Medical College in 1980. In 2013 he completed a Master of Studies in Law (MSL) from UC Hastings College of the Law.

Lustig has authored 105 peer-reviewed articles and 65 reviews. He is a former chair of the obesity task force of the Pediatric Endocrine Society, a member of the obesity task force of the Endocrine Society, and sits on the steering committee of the International Endocrine Alliance to Combat Obesity. He is married with two daughters and lives in San Francisco.

Lustig was a coauthor of the 2009 American Heart Association guideline on sugar intake, which recommended that women consume no more than 100 calories daily from added sugars and men no more than 150.

Reception Lustig's statements regarding fructose as a "poison" and the primary cause of weight gain have been disputed because claims of fructose toxicity are unproven. Excessive consumption of fructose-containing beverages is likely a cause of weight gain and obesity in many people due to the additional caloric intake rather than a specific toxic effect of fructose. Fructose when consumed in excess as a sweetening agent in foods and beverages is associated with surplus calories and greater risk of obesity, diabetes, and cardiovascular disorders as components of metabolic syndrome. Other reviews indicate that fructose has no specific adverse effects compared to any other carbohydrate.
