Gary Greenberg has been writing professionally for more than 40 years, primarily as an award-winning newspaper reporter and editor. His new book, The Beer Diet: How to Drink Beer and Not Gain Weight, discusses the “beer belly” myth, the nutritional components of the most popular beverage in the world, why he thinks the mushrooming of craft beer micro-breweries is more than a passing fad, how to mitigate the dangers of beer, and the secret to not gaining weight when drinking beer.
