The Fat Switch
January 1, 2012
Five stars for scientific rigor. Three stars for accessibility to the average reader.
Dr. Johnson has written an excruciatingly detailed analysis of how dietary fructose triggers a complex cascade of biochemical events to accumulate fat and reduce energy output. He is not the first expert to arrive at this conclusion, but his book goes into far greater detail than any I have read on the precise physiological mechanism by which fructose causes us to pork up.
Physicians, dietitians, researchers and others with an affinity for chemistry will love this book. But if you're looking for fresh ideas on how to lose weight, you may be disappointed. In fact, you may stop reading long before Johnson ever gets around (in chapter 21) to offering familiar advice on how to avoid or reverse the fructose effect: fewer starches & simple carbs, less sugar & artificial sweeteners, more veggies and prudent exercise. Sensible stuff, but hardly radical.
What sets Johnson's book apart is not his prescription but his diagnosis -- and the depth with which he explains a biochemical basis for the epidemic of obesity in the United States.
A book that is sure to fascinate the technically minded, but overkill for the lay reader.
