Art De Vany just published a provocative article last month, asserting that fat is really the ultimate fuel for our bodies in the sense that we were designed to burn it very efficiently.  You’ll need a subscription to access the full article, but Art’s work is always thoughtful and very well-researched.

“The next high performance fuel will be fat when the research finally gets it right,” Art writes. “It is simple, our ancestors were capable of amazing performances and did it on fat, not carbohydrate.”
