Figure 1. Inverse linear relationship between caloric intake and lifespan in mice.
C3B10F1 females were individually housed and placed on controlled diets (115kcal/wk, 85kcal/wk, 50 kcal/wk and 40kcal/wk) from weaning (n =49, 57, 71, 60 respectively). Animals with the highest caloric intake died earliest and survival improved with increased caloric restriction.
