A Big Fat Crisis

October 28, 2013
With a kind but brisk bedside manner, RAND Corporation scientist Cohen (co-author of Prescription for a Healthy Nation) delivers a diagnosis in layman’s terms in this powerful book: two-thirds of American adults and one-third of children are overweight or obese, not because of a lack of self-control, but because of the “modern food environment” that makes it easy to consume too many calories. In the first half of the book, Cohen presents numerous research studies that level myths about “mindful” eating, instead arguing that we’re “biologically designed to overeat” and easily influenced by 24-hour fast-food drive-thrus, oversize restaurant portions, supermarket displays, candy in checkout aisles, and TV commercials. She argues for a “critical paradigm shift”: to view the epidemic as a public health crisis and institute controls that guide eaters to “choose health over heft.” Anticipating resistance, Cohen spends the rest of the book defending government interventions, citing examples like ratings for restaurant hygiene and conjecturing how “common-sense regulations” resembling those on alcohol sales might “make unhealthy foods” less accessible and enticing. While Cohen believes that collective action is the only real solution to epidemic, she also helpfully suggests ways to modify one’s food environment and offers dietary guidelines in the appendix.

Starred review from December 1, 2013
Cohen, an epidemiologist and medical doctor at the RAND Corporation, makes a convincing case that obesity involves far more than a failure of willpower. Were people really more disciplined 30 years ago, when only one in six U.S. adults was obese, instead of the one in three today? Unlikely, she says. Physiologically, our capacity for self-control has not shrunk over the past several decades. She blames both the way humans are wired to overeat when presented with the opportunity and the transformed food environment, which makes large portions of cheap, high-calorie foods too easily available. Little nibbles add up: The average individual weight gain of 22 pounds over the past 30 years in the U.S. can be explained by our eating just seven extra calories per day. Cohen proposes standardizing portion sizes and running counter-advertising against unhealthy food products. Her other ideas include following the model of state limits on the number of places that can sell alcohol: why not do the same with doughnut shops and ice cream parlors? And why not restrict all-you-can-eat buffets, and use warning labels, like those for cigarettes and alcohol? Though some ideas seem far-fetched, Cohen certainly presents a fresh, thought-provoking take on how to fight the obesity epidemic.(Reprinted with permission of Booklist, copyright 2013, American Library Association.)
