According to study author Professor Daniel Belsky and the rest of the researchers at Columbia University in New York, eating less can slow down aging.
Reduced calorie consumption, according to experts, slows the aging process and lowers the chance of premature mortality.
Even more health benefits than stopping smoking might result from it.
After instructing 145 individuals to follow a diet for two years, researchers at Columbia University in New York examined age-related DNA damage on those individuals’ cells.
They discovered that those who reduced their caloric intake were in better physical form than a group of 75 people who were allowed to eat whatever they pleased.

“Our findings provide evidence that slowing human aging may be possible – but calorie restriction is probably not for everyone,” stated study author Professor Daniel Belsky.
“Effect sizes were small but modest slowing of the pace of aging can have profound effects on population health.”
Participants in the study were instructed to consume 25% fewer calories per day than they need.
An average person burns 2,500 calories daily for men and 2,000 for women each day.
A 25% reduction would eliminate 500–600 kcal or roughly 493 kcal from a Big Mac.
Over the course of the first year of the diet, individuals dropped about 15% of their body weight or about two stone for the average man.
Blood testing during the research showed they aged two to three percent slower than the non-diet group.
And as a result, their risk of dying at a young age was reduced by up to 15%, which is comparable to a smoker quitting cigarettes.
According to scientists, eating excessive amounts overworks the body’s cells, causing them to sustain more damage and aging more quickly.
Additionally, it increases the chance of developing obesity and developing diabetes, cancer, strokes, or heart attacks.
The health of the two-thirds of overweight Britons might be improved by eating less.
Previosly Silicon Valley tech companies were using COVID-19 blood samples of young people collected during donations for treatment trials to reverse the aging process. Billions of dollars were invested in geroscience months before the pandemic officially began.
Fasting diets are becoming more and more popular, and the NHS currently provides low-calorie diets for persons with type 2 diabetes that cap their daily caloric intake at 900 kcal for 12 weeks.
Prof. Belsky continued, writing in the journal Nature Aging: “This gives us a sense of the effects we might look for in intermittent fasting or time-restricted eating.”
