Many people overeat. As a result, more and more people suffer from obesity, hypertension, coronary heart disease, cancer and other conditions related to overnutrition. Prolonged overeating also leads to damage to the gastrointestinal system and metabolic disorders. Thus, the accumulation of metabolic waste in the body will generate various diseases.
Researchers have determined that aging can be easily delayed just by reducing the level of calories absorbed by 25%, according to an article published by the British newspaper The Daily Telegraph.
The number of calories recommended per day for women is 2,000, and for men 2,500 calories. Cutting calories by 25% can have many health benefits, preventing premature death.
Researchers at Columbia University conducted an experiment on 220 healthy adults. Half of them were asked to reduce their calorie intake, and half of the people ate according to traditional healthy eating guidelines. The result shows that the rate of aging of the members of the first group slowed down by 2-3%, which means that the risk of premature death decreased by 10-15%. The benefits of this measure are similar to quitting smoking.
A researcher from Columbia University claimed that the result of this experiment proved that delaying aging may be possible.
A calorie-restricted diet requires that intake be lower than the recommended level, but sufficient nutrients must be provided, along with the necessary vitamins and minerals.
Some previous research on worms, flies and mice has shown that reducing calorie intake helps slow aging and prolong life.
The result of research on worms shows that the diet contributes to the extension of life by 40%. Also, the limitation of calories absorbed by monkeys means that the rate of diseases related to age, such as cancer, heart disease, diabetes, has decreased.
New research proves, for the first time, that calorie restriction promotes longer life in healthy people.
It is easy to monitor the aging of short-lived animals, while changes in humans can only be observed after several decades. As such, in human research, by monitoring DNA changes in the blood, researchers can assess, in a relatively short time, the rate of aging.
The researchers also found that the majority of people participating in the experiment could not persist with a 25% reduction in the level of absorbed calories, but only with 20%, which proved that the measure is effective even if the restrictions are not very strict.
The researchers also followed the participants after the experiment was completed, to clarify whether this type of intervention can produce long-term influences on health. A number of previous researches have shown that slowing aging can lead to a reduction in the occurrence of heart disease, disability, stroke and dementia.
Experts aren’t sure why limiting calorie intake can help delay aging and extend life. But he believes the measure is likely effective in improving inflammation and sugar metabolism, protecting cell functions and DNA. In addition, it may help reduce oxidative stress, which damages cells and tissues.
However, some people who have applied calorie reduction have complained of side effects such as decreased bone density, muscle quality and exercise capacity.
