Center for Science in the Public Interest has just done calorie counts on meals served at Olive Garden and Romano’s Macaroni Grill. Pretty impressive! I don’t think you need complicated arguments about fat vs. carbohydrates to explain why people gain weight when they routinely eat meals like these. While I thoroughly agree that 50 or 100 extra calories a day do not really add up to pounds a year (because metabolism compensates for small differences), we are talking here about thousands of extra calories a day. Italians in Italy don’t eat this much, or at least they didn’t used to.
