Registered dietitian and author of Boosting Your Metabolism for Dummies Rachel Berman talked to Brian about the new Coca-Cola commercial that came out, which states that, “All calories count, no matter where they come from.”  Rachel said that while this is true, all calories are not created equally.  “The sugar that you find in sweetened beverages does not act the same in our bodies as sugar from fruit or natural sources,” she explained.
