Calories vs. Carbohydrates – Gary Taubes (AHS12)

Gary Taubes’ excellent talk, “Calories vs. Carbohydrates: Clearing Up the Confusion Over Competing Paradigms of Obesity”, from the Ancestral Health Symposium 2012 (AHS12). Of particular interest to me is his discussion of the competing paradigms of obesity: the result of an individual’s failure to regulate consumption vs. a problem of adipose storage mechanisms. Well worth watching.

Note: If you have trouble with the video below, try viewing it here. It seems like there are some problems with hosting permissions that vimeo/AHS needs to work out.

New recommendations for _maximum_ sugar consumption is 150 calories sugar a day for men, and 100 calories sugar a day for women. That works out to about 37 grams of sugar a day for men, and 25 grams of sugar a day for women. For reference, Again, that’s the _maximum_ recommended intake by Dr. Robert Lustig.

Dr. Robert Lustig – The Skinny on Obesity – Episode 4

In this the fourth episode of the series, Dr. Lustig looks at sugar’s effects on brain chemistry, specifically, how our reward system (mediated by dopamine in the nucleus accumbens) is changed in response to chronic overconsumption of sugar.

Specifically, Lustig asserts that sugar downregulates the same dopamine system in the nucleus accumbens (reward center of the brain) that drugs like cocaine do. In this sense, an addiction marked by domamine resistence in the pleasure center is an additional driver of obesity in addition to the leptin and insulin resistence he described in previous videos. All, of course, are the result of sugar consumption
