One study found that old, fat flies became healthier and lived longer when they went on a diet.

The Paris experiment shows that it is never too late to go on a diet.
Researchers at the University of Connecticut in the US found that fruit flies that ate a diet that mimicked the unhealthy diet of modern humans (△high sugar, △high protein and △high calorie ) showed similar metabolic changes to obese humans. At this point, the researchers conducted an experiment based on the question: “Can old obese flies change their metabolism if they switch to a low-calorie diet?”
First, flies raised on a high-calorie diet lived a short life of 80 days, while flies raised on a low-calorie diet survived about 120 days, 50% longer. The researchers first conducted an experiment on 20-day-old young fruit flies that had been on a high-calorie diet. When the diet of young fruit flies was changed to a low-calorie diet, they survived as long as flies that were on a low-calorie diet from the first day of life.
So, old fruit flies that had been on a high-calorie diet for 50-60 days after birth switched to a low-calorie diet. So, despite the malfunction of the organs and the presence of a lot of body fat, the metabolism changed and the mortality rate dropped dramatically. Although it was not the young flies that changed their diet early, it was confirmed that lifespan increased to some extent.
As a result, the researchers stated: “Flies that have lived a significant portion of their lives on a high-calorie diet may benefit from increased life expectancy simply by switching to a low-calorie diet. Similarly, changing a healthy diet in obese people in later life it may also have a decidedly beneficial effect on their health.” “It suggests it could have an impact,” he said.
In general, obesity means a body mass index (BMI) of 25 or more. Compared to non-obese people, obese people have a higher risk of developing various complications such as hypertension, diabetes, hyperlipidemia, fatty liver, and arthritis. Furthermore, it is easy to get various cancers such as colon cancer, pancreatic cancer, and breast cancer.
As a result, obese people die 2 to 5 years earlier than people of normal weight, and studies have shown that, in the case of severely obese people, their life expectancy is reduced by 6.5 to 13.7 years in the same comparison.
