The secret to a long and healthy life, according to research

Latest research done on people specifies that calorie-restricted foods can slow down the process of aging at a cellular level and increase longevity.

If you want to live longer? Then resist your internal appetite and eat less. That’s the assumption of numerous studies which link calorie-restricted diets and healthy aging.

The calorie-restricted intakes may improve mood and even protect against age-related illnesses that damage the body. Individuals can use this device to possibly increase their life spans, say experts. One study published in Cell Metabolism journal resolved that cutting calorie consumption by 15 percent over two years can slow down aging and defend against syndromes such as diabetes, cancer, and Alzheimer’s.

The diets work by slowing the metabolic rate and decreasing free radicals related to chronic diseases. A slowed metabolism is associated to longer life in many animal species, said Leanne Redman, Ph.D., associate professor of clinical sciences at Pennington Biomedical Research Center in Louisiana and a co-author of the research, described.

“Energy is controlled more proficiently,” added Rozalyn Anderson, Ph.D., an associate professor at the University of Wisconsin School of Medicine and Public Health. “Resilience pathways are triggered.” Fat, for instance, is used rather than stored.

Garbage in, garbage out

Researchers have long known that calorie-restricted diets can be a strong anti-aging armament. The limitation is that the researches have generally been done on animals. The most current research was one of the first to focus on humans.

Participants were 53 non-obese, healthy individuals between the ages of 21 and 50. The investigators said they revealed that even healthy and lean people can benefit from calorie-restricted diets. Furthermore, several biomarkers for aging were reduced and health improved according to the study.

“One thing is sure,” Anderson said. “If you eat and weigh less, you live longer.” A different, more extreme low-calorie diet research published in Science Translational Medicine exposed that so-called fasting-mimicking intakes practiced for five days a month for three months can help the body with aging. The diet used was plant-based and comprised vegetable soups and energy bars.

Calorie-restricted diets work because it cleans the garbage out of your cells, described Barry Sears, Ph.D., author of the Zone Diet book series and president of the Inflammation Research Foundation.

“The more calories you consume, the more free radicals you produce,” he said. “They can cause damage.”
Yes, new studies on humans are required, say experts. Yet, many information can also be gathered from animals study, say experts. An earlier study published in Nature Communications revealed that calorie-restricted foods stimulated health welfares for monkeys.

And another study completed at Washington University School of Medicine in St. Louis showed that some animals lived up to 50 percent lengthier after knowingly cutting calories.

Energy efficiency is the key

Some specialists fear that people could cut back calories too much or in the wrong way. Thus causing reductions in bone density or muscle mass. “You require fuel to be alive and active,” described Anderson. “The majority of calorie consumption keeps the ocean liner flooded.”

Limiting calorie consumption by 15 percent is not severe, noted Priya Khorana, EdD, a doctor of nutrition education at Teachers College, Columbia University. But a 25 percent calorie reduction wouldn’t be healthy, she said.

“Plus in the long run, these intakes are not as effective as modest nourishments,” Khorana said. “Getting a balanced nutrient-rich diet is vital to success.” And, she adds, exercise is also significant.  So just restricting calories without receiving decent nutritional data could mean missing out on vital minerals and vitamins.

In the two types of research on humans, members took vitamin complements for the surety that the foods were still nutritionally rich. The result is that proficiently using energy is the sign for longevity — accompanied by healthy eating. “All diseases are different,” she said. “But they are all related with aging. And calorie-restricted intakes work.”
