For weight loss, people often adapt to different types of dietary and lifestyle changes. However, how the body adapts to the diet helps in impacting the longevity of a person in a positive way. A recent study led by Gary Churchill, The Jackson Laboratory demonstrated how different dietary choices can impact longevity differently. Calorie restriction and intermittent fasting can have significant life-extending benefits, the research confirmed.
The research was conducted on 937 genetically diverse female mice – the mice were divided into five categories – one with unrestricted access to food, two with calorie restrictions and two with intermittent fasting. Then regular health assessments and blood tests were conducted on those mice throughout their lives to observe the effect of their diets.

Results of the study:
The study observed that calorie restriction and intermittent fasting improved the lifespan of mice than the ones who had unrestricted access to food. It was further observed that the mice that fasted for one or two days per week experienced lifespan extensions – the mice that fasted for two days lived longer than the mice that fasted for one day. Even when they consumed the same amount of food like their unrestricted counterparts, the calorie restriction and intermittent fasting added to their lifespan.
Gary Churchill, Karl Gunnar Johansson Chair and professor at JAX who led the study, in a statement, stated that a moderate level of calorie restriction and intermittent fasting can help in improving health and lifespan.

{{/usCountry}}The study challenges the old notion - calorie restriction can alleviate the negative effects of obesity, thereby significantly improving lifespan. However, the study further suggested that there is a more complex model of mechanisms at play that helps in improving longevity with calorie restriction.
