Low calorie diet longevity, should not use a short life to verify the happiness of eating goods.

research shows that strict food intake can help fish, old Rats and monkeys live longer. But for a long time, similar studies on human beings are rare. Now scientists have discovered that when humans strictly control calorie intake, they can also reduce their metabolism and may delay the aging process. The latest research results are published in cell metabolism. The
researchers found that the biggest difficulty was to find volunteers who were willing to participate, after all, to cancel about 25% of their calories from their breakfast, lunch and dinner, and they had to be unable to be overweight.
eventually the clinical scientist, Redman, found 53 healthy volunteers, 1/3 of them eat their normal diet, and the rest of them have strict calorie control for two years. "I don't know if you understand the severity of this experiment, after all, you must have a strict diet every day." She said, "but the volunteers agreed." After a year of
the volunteers, those who had control of the heat, unintentionally reduced their weight by an average of 25 pounds, while the volunteers in the control group increased by an average of 4 pounds.
but weight loss is not the most important. Redman wants to know whether calorie control affects aging. She asked the volunteers to stay in a special room for 24 hours, which could record their metabolic rates, including oxygen and carbon dioxide. It turns out that those who reduce calorie intake need less oxygen than other groups. So the whole cell and body system become more efficient. And scientists have long proved that if less oxygen is needed in the process of energy consumption, the free radicals of the harmful by-products will also decrease, and the free radicals are generally acknowledged to be the cause of accelerated aging.
this research is published in cell metabolism.
but this discovery does not directly prove that reducing calorie intake can help people live longer, because scientists have to spend a whole lifetime tracking the volunteers, and scientists have to live longer, perhaps to prove it. But it does find that when calorie cuts are cut, blood pressure, cholesterol and triglycerides are indeed lower, and the increase in these values does lead to a disease that shortens life. The real challenge of
is that people may not be willing to control their diets strictly because low metabolism leads to other problems.
a research biochemist at the University of Southern California said that taking care of your own calorie intake at the time of the year might mean a fast increase at the end of the year. Moreover, excessive control of heat can also lead to muscle loss and immune system dysfunction.
but more importantly, long-term control of calorie intake may face a dilemma for most people. It will take a lifetime to verify that he has been able to go on a diet or not to have a long life, or an open belly, which can not overcome the human instinct.
