The conventional wisdom, often repeated, is that burning more calories than we ingest prevents us from getting fat. Gary Taubes, health policy investigator for the Robert Wood Johnson Foundation at the University of California at Berkeley and author of the books Why We Get Fat and Good Calories, Bad Calories, discusses why his evaluation of the research leads him to the conclusion that the traditional advice is fundamentally wrong. He joins host Lisa Dandrea Lenell to talk about the research on carbohydrates, not calories, as the culprit in weight gain and the advice he believes will help patients successfully lose weight, and the core perspective change he believes will keep the weight off.
