Shortage and weight gain shorten age

A study published in the latest issue of the medical journal Lancet, version of diabetes and endocrinology, found that being overweight or underweight could lead to life expectancy of less than 4 years compared to expectations. The study, the largest of its kind, involved nearly two million people registered with doctors in the UK.

Researchers who prepared the study found that, at age 40, those at the upper limit of the "healthy" body mass index had a lower risk of dying from illness. Those at the top and at the end of the BMI "risk" were more likely to live shorter lives. It should be noted that the healthy body mass index varies from 18.5 to 25 and that, for doctors, this is the best way to determine whether a person is obese or not. In the context of the study, the life expectancy of obese individuals was less than 4.2 years in men and 3.5 years in women, compared with those with a healthy BMI .

"When the fat is too low, the body can not store sufficient amounts of certain vitamins (A, D, E, K)," said Sader. "The health problems associated with low body fat are also important. accumulate over time, which are stored only in fat Because the fat in the body is important for the formation of nerves and cells, their absence causes an imbalance in the composition of organs and basic functions of the body. Fats also have an important relationship with hormones, women and masculinity, and their low availability can lead to fertility problems. "
