Popular coverage of diet and weight-loss strategies often summarizes the bottom line with a twist on President Bill Clinton’s campaign mantra, “It’s the economy, stupid.” When it comes to managing your weight, as this line of thinking goes, “It’s the calories, stupid.” But a new study published in the American Journal of Clinical Nutrition challenges this conventional wisdom. “It builds on earlier work that suggests all calories are not the same,” says Dariush Mozaffarian, MD, DrPH, dean of Tufts’ Friedman School and senior author of the study. “All foods have complex mechanisms that help or hinder weight long-term.
