The study was conducted on 937 genetically diverse female mice; The mice were divided into five categories: one with unlimited access to food, two with calorie restriction, and two with intermittent fasting. Routine health assessments and blood tests were then performed on the mice throughout their lives to observe the influence of their diet.

Research result:
The study observed that calorie restriction and intermittent fasting increased the lifespan of mice compared to mice that had unlimited access to food. Additionally, it was observed that mice that fasted for one or two days a week experienced longer lifespans: mice that fasted for two days lived longer than mice that fasted for one day. Even when they consumed the same amount of food as their unrestricted counterparts, calorie restriction and intermittent fasting increased their life expectancy.
Gary Churchill, the Karl Gunnar Johansson Chair and professor at JAX who led the research, said in a statement that moderate levels of calorie restriction and intermittent fasting can help improve health and life expectancy.
