Calorie Restriction and the Heart
Now that funding is coming into calorie restriction studies, more detailed examinations of the health and longevity benefits have been forthcoming. EurekAlert provides one such example: "Studying heart function in members of an organization called the Caloric Restriction Society, investigators at Washington University School of Medicine in St. Louis found that their hearts functioned like the hearts of much younger people. ... Ultrasound examinations showed that the hearts of people on caloric restriction appeared more elastic than those of age- and gender-matched control subjects. Their hearts were able to relax between beats in a way similar to the hearts in younger people. ... This is the first study to demonstrate that long-term calorie restriction with optimal nutrition has cardiac-specific effects that ameliorate age-associated declines in heart function."

Did you know that simply smelling food causes CR diets to almost completely reverse?
@John Doe: in flies, yes it has been shown that sensing food has interesting effects. It remains to be seen how that pans out in mice and humans. See:
