Scales Outdoor, Fitness And Body Fat Key To Health

Scales outdoor, fitness and body fat key to health

bathroom scale can show a good number, but the amount of weight that is fat, not muscle? The new study adds to evidence that the scale does not always tell the whole story when it comes to the health risks associated with weight loss.

Keeping a low body fat is more important for healthy aging are low overall weight, the researchers reported Monday in the journal Annals of Internal Medicine. Another study found that young people who are not physically fit are at greater risk of developing type 2 diabetes later in life, even if your weight is healthy.

Here are some things you should know:

Is it important to not BMI?

The body mass index yes., Or BMI is a measure of a person's weight in relation to their height. For many people, this is a lot of evidence to say if they are overweight or obese, and thus at greater risk of heart disease, diabetes, and premature death. Generally, a BMI of 25 and above indicates overweight, while 30 and above indicates obesity. A person who is 5 feet 9 inches (1.52 meters) to reach the threshold of obesity to 203 pounds. (92 kg)

But it does not fit

Some people have a high BMI because they are more muscular. More common are people who harbor very little muscle and excess body fat, even if the BMI is in the normal range.

body composition changes with age, with the percentage decrease in the ratio of muscle and body fat increases. Slowing down your metabolism, making it easier to put on pounds in middle age, even though people do not change how they eat and how much exercise.


Results Fat

Dr. William Leslie, the University of Manitoba wondering if your body fat measured can not help explain the controversial "obesity paradox", where several studies have shown that to be quite overweight later in life can be good for survival. It tracked 50,000 Canadian aged and elderly, especially women, who have undergone screening for osteoporosis weakens bones. They screening X - ray known as DXA by dual X-ray absorptiometry - measures bone and allows also estimate the fat.

A higher percentage of body fat, regardless of a person's body mass index, was associated with decreased survival, says Leslie. Risk begins to rise when body fat is in the order of 36 percent to 38 percent. Interestingly, the skinny is also associated with decreased survival, may reflect age-related weakness.

"It's not just the amount of body you have, but what you really finished," said Leslie.

Revenue And Fitness

A high BMI is one of the biggest risk factors for type 2 diabetes, but a second study published in Annals Monday showed people still can be risky if they are thin, but the physically fit.

Researchers in Sweden and New York to check the records of 1.5 million Swedish men for 18 years receive a medical examination for military service and monitored how many developed diabetes several years later.

Low aerobic and muscle strength under all conditions associated with an increased risk of diabetes - regardless of whether people were normal weight or overweight. He marks of additional risks.

What were the results?

For diabetes, "ordinary people who can not get advice from lifestyle changes if they persist or are not feasible because of the weight that is lower than the perceived risk," wrote obesity expert Peter Katzmarzyk of the Pennington Biomedical Research Center of Louisiana, he was he did not participate in this study.

The study also shows fitness during adolescence can have a lasting impact.

And Leslie said the physician should consider the patient's body composition, body weight is not just a health assessment.

Most people do not benefit from a DEXA scan to fat, says Dympna Gallagher, who heads the human body composition laboratory at Columbia University Medical Center and believe that this test for research of real life.

Another method to determine the scale balsa body measurement of skin folds "bioimpedance" using a small electric current, but they all have different degrees of fault, said Gallagher. Moreover, normal body fat varies with age and there is no agreement on the best cuts to health, he said.

His Recommendation: 

Control your life, even if normal BMI. Abdominal fat, a character in the shape of an apple, is more dangerous than fat stored on the hips. The government says that men have a higher risk of health problems if their waist circumference greater than 40 inches (100 centimeters) and 35 inches (90 cm) for women.
