Christopher Gardner, a nutrition scientist at Stanford University who was not involved in the new study, said that after decades of research but little success in fighting obesity, “it has been disappointing that the message being communicated to the American public has been boiled down to ‘eat less and exercise more.’”
"An underlying assumption of the ‘eat less’ portion of that message has been ‘a calorie is a calorie,’" he said. But the new research "sheds light on the strong plausibility that it isn’t just the amount of food we are eating, but also the type"”
