Keeping track of the foods you eat is an important strategy for weight loss, but continuing to monitor what you eat is also important to prevent regaining that weight. Now, a new study finds that stopping food tracking is linked to regaining weight. In order to prevent re-gaining weight, people should make an effort four months after starting a diet to refocus on food tracking, according to the study, presented here Sunday (Nov. 13) at the American Heart Association's annual meeting called the Scientific Sessions.
