But the whole picture is not so simple. Weight loss is not always healthy nor is restricting your calorie intake, especially if your BMI is low to start. Some scientists have warned that, depending on evidence in animals, this can negatively affect wound healing, metabolism and bone density. Let’s take a look at the benefits this week – and risk -calorie restrictions.

Eating less animals can be kept alive for longer. This remarkable discovery has been published in scientific magazines for the last 100 years. It seems that almost every animal has been studied – everything from small nematodes and fruits to mice, mice and even monkeys from flies. It can increase the lifetime of rodents between 15 and 60%, depending on which study you see.

The effect of calorie ban is more reliable than the major contenders for “anti-aging” drug. Both rapamycin (an immunospressive drug used in organ transplant) and metformin (a diabetic drug) have been postponed as a possible longevity medical science. And both have been found in some studies to increase the lifetime of animals.

But when scientists saw 167 published studies of those three interventions in research animals, they found that calorie ban was the most “strong”. As His researchPublished in the journal Old age cell On Wednesday, the effect of rapamycin was somewhat comparable, but the metformin was not effective anywhere.

“This is a pity for many people who are now taking off-label metformin for lifetime expansion,” Lecturer at biogerontology at Lancaster University said in a statement. “Let’s expect it or many adverse effects.” Nevertheless, for calorie ban, so far is great.

At least this laboratory is good news for animals. What about people? In addition, on Wednesday, another team of scientists published a separate review of the research that investigated the effects of calorie ban and fasting on humans. The review assessed 99 clinical trials, consisting of over 6,500 adults. (As I said, caloric restrictions have long been an active area of ​​research.)
