can you be fat and fit? more health experts say yes - energy storage devices

Health experts now think it is entirely possible to be overweight. -but still fit.
They say measuring just one person's BMI, that is, measuring body fat based on height and weight, can be misleading.
On the one hand, muscles are heavier than fat.
People with developed muscles may actually have BMIs, classifying them as overweight or even obese.
A growing number of health experts say better measures to measure overall health include not only BMI, but also "health" tests. Cardiologist C. Noel Bairey-
Merz is one of these experts.
She is the director of the Women's Heart Center and the Cedar Heart Center for Prevention and Rehabilitation-
Sinai Heart Institute
According to her research, she says "health" is better than "obesity" now ".
"Those who are in good health can walk for 30 to 60 minutes without having to stop, she said;
Who can climb two stairs without win wordy;
Or who can do some mild to moderate aerobic exercise-
For example, take a brisk walk or jog.
Such daily exercises can enhance cardio-pulmonary function, bones and muscles, and how the body handles oxygen.
The higher the efficiency of these functions, the greater the fitness effect.
Fitness can be measured by a simple questionnaire that asks the patient about the level of physical activity.
If the doctor is particularly concerned about health, he or she can perform stress tests, which usually require the patient to walk quickly or jog on the treadmill for a period of time while measuring blood pressure and oxygen levels.
In a study, Thin rey-
Merz found that women with regular exercise and overweight are less likely to have heart disease than women with normal weight who do not exercise.
On the contrary, women with normal weight who do not exercise will increase their risk of cardiovascular disease.
"They don't have cardiovascular reserves," she said . "
"They sit quietly, work on the computer, jump on the internet, watch the dvd, and it's all good.
Everything was fine during the break.
"But when they really have to do something, or when they face real cardiovascular stress ---
Like a car accident, a heart attack or pneumonia. -then, Bairey-
Merz says they don't have a fitness level that can help them do a good job and survive.
She said they will face more risks of premature death, disability and disease, adding that there is evidence that overweight is protective when people are sick.
"Fat is our energy storage device.
In a way, it's kind of like there's something in the bank, "she said.
When weight gain, the HandyA study found that overweight people had a lower mortality rate than their peers who were underweight, obese, or most surprisingly normal weight.
According to Vickrey-
Merz, it may be beneficial to have a few more pounds.
"If you are seriously ill in ICU [
Intensive Care Unit
You are often on a ventilator.
You can't eat, drink water in your veins, and there is a lot of pressure, such (a severe skin)
"Burns, pneumonia, or heart disease are burning calories," she said . "
But is it always OK for the extra 10 pounds as long as you exercise?
Health experts say not necessarily.
When metabolism slows down around the age of 50, men tend to gain weight in the abdomen, while women tend to gain weight in the hips and thighs.
It turns out that one is more dangerous than the other.
Belly fat is worse than fat elsewhere in the body.
Arun S. , an expert in geriatric medicine.
Karlamangla is a professor and clinician at the University of California, Los Angeles.
In a study, he analyzed the health status of more than 4,000 men and women across the country.
He found that the death rate of men with a waist circumference greater than the hip increased by 75%.
For women, the risk gradually increases as the waist size increases.
The researchers don't know why abdominal fat is particularly dangerous, but think it interferes with the body's ability to process sugar.
Abdominal or visceral fat increases insulin resistance, increases the level of insulin floating in the body, increases the amount of glucose in the body, and ultimately leads to diabetes.
Diabetes increases the risk of heart disease and stroke.
To reduce abdominal fat and maintain or enhance physical fitness, the federal government recommends a moderate exercise of 30 minutes per day.
If you want to lose weight, increase your exercise time to 60 minutes a day.
Health experts like Barry
Merz recommends that doctors pay as much attention to "health" as to "obesity.
