Dr. Robert Lustig is a professor in the UC San Francisco Division of Pediatric Endocrinology, and he has previously been featured on UCTV with his talk, Sugar: The Bitter Truth, of which this talk is an update. He argues that fructose (too much) and fiber (not enough) appear to be cornerstones of the obesity epidemic through their effects on insulin.
A little background from Wikipedia:
[Dr. Lustig] practices in the field of neuroendocrinology, with an emphasis on the regulation of energy balance by the central nervous system. He also has a special interest in childhood obesity.
Lustig came to public attention through his efforts to establish that fructose can have serious deleterious effects on human (especially children's) health if consumed in too large amounts. On May 26, 2009, he delivered a lecture called "Sugar: The Bitter Truth" which was posted on YouTube the following July and "went viral" with some 3.47 million viewings (as of Apr 28, 2013). In his lecture, Lustig calls fructose a "poison" and equates its metabolic effects with those of ethanol.
Lustig is the author of Fat Chance: Beating the Odds Against Sugar, Processed Food, Obesity, and Disease (2012).
