Study: Eating Less Can Prolong Your Life

Study: Eating Less Can Prolong Your Life

Preliminary research indicates that even moderate reduction of caloric intake could impact your lifespan.

In case you need additional motivation to finally go on a diet, a new study might provide it. The paper, published in the journal Cell Metabolism, revealed that people who cut their caloric intake by 15 percent over two years had a significant decrease in their metabolism. They’ve also seen improvements in biomarkers associated with slower aging and longer lifespan: namely, participants in the study they developed a lower core body temperature, lower blood sugar and insulin levels, and significant drops in hormones that moderate metabolism.

Or, in other words: after two years of eating less, the participants in the study had results consistent with those of people with a longer lifespan. The connection between long lives and caloric intake has already been noticed in animal trials, but the study conducted at the Pennington Biomedical Research Center is the first to confirm it when it comes to humans.

53 healthy men and women between the ages of 21 and 50 participated in the study that lasted for two years. They were divided into two groups: one didn’t change anything about their diet, and the other group cut back on their caloric intake. Even though none of the participants were obese, the group lost around 20 lbs on average, but it’s not the weight loss that sparked the excitement of scientists (it was more of a perk for the participants). The real reason is that the study offers new insights into the aging process, or, rather, gives confirmation of previous findings.

Even if there were no slow aging perks to eating less, we know that certain forms of reduced caloric intake, such as intermittent fasting, have proven to have significant health benefits for some people. However, that doesn’t mean that calorie restriction is something that works for everyone: before you make any drastic changes in your diet, it’s best to consult with your MD. Considering how much influence nutrition can have on our wellbeing, it’s vital not to take any chances: talking to a professional is the only way to ensure you’re making the right choice!
