I'm skeptical that you can derive these conclusions from those assumptions. Here in Canada they are required to post the caloric content of the hot dogs, so even a 10% change in content will be obvious. A 37% cut means they would have changed the signs from 540 calories to 340, but nothing like that has happened.
