For most of us, body fat has a bad reputation. Covily Things Prague Women's thighs for beer bellies that may appear in middle-aged men, fat is typically something we agonize, contempt and try to exercise.
But for scientists, fat is intriguing - and becoming more every day. "Fat is one of Organs most fascinating organs out there," says Aaron Cialy, MD, PhD, Medicine instructor at Harvard Medical School and a research member in the center of Joslin Diabetes in Boston. "We're just beginning to understand fat."
"Fat has more functions in the body than we thought," agrees Rachel Whitmer, PhD, research scientist at the Permanent Kaiser Research Division in Oakland, California, who studied the links between the fat and health of the brain.
.To get slim in fat, Webmd asked four fat specialists - who, not surprisingly, prefer not to be called fat specialists - to fill us.
Fat is known to have two main purposes, says Susan Frito, PhD, director of Boston Obesity and Nutrition Research Center of Boston University and a longtime researcher in the countryside.
- Fat stores excess calories securely so that you can mobilize the fat stores when you are hungry. Fat releases hormones that control metabolism.
But this is the wide image of brushstroke. Read more information on various types of fat - brown, white, subcutaneous, visceral and belly fat.
How To Do Faster Way To Fat Loss - The Truth About Fat
Brown fat got a lot of buzz recently, with the discovery that they are not the most useless greasy scientists had thought.
In recent studies, scientists have discovered that skinny people tend to have more brown fat than overweight or obese people - and that when stimulated, it can burn calories. Scientists are looking at you as a potential treatment of obesity if they can discover a way to increase brown fat or stimulate existing brown fat.
It is known that children have more brown fat than adults, and is what helps them warm up. Brown fat stores decline in adults, but still help with the heat. "We show brown fat is more active in people in Boston in colder months," says Ciay, leading to the idea of sleeping in Chillier rooms to burn some more calories.
Brown fat is now thought to be more like muscle than as white fat. When activated, brown fat burns white fat.
Although the more leaning adults have more brown fat than heavier people, even their brown fat cells are greatly overcome by white fat cells. "A 150 pound person can have 20 or 30 pounds of fat," says Cypess. "They will only have 2 or 3 ounces of brown fat."
But what 2 ounces, he says, if maximally stimulated, could burn 300 to 500 calories a day - enough to lose up a pound in a week.
"You can give people a drug that increases brown fat," he says. "We're working on one."
But even if the drug to stimulate brown fat pans outside, Ciale warns, it will not be a cure - all for weight problems. It can, however, help a person achieve more weight loss combined with a sound diet and exercise regimen.
White fat is much more abundant than brown, experts agree. White fat work is to store energy and produce hormones that are then secreted in the bloodstream.
Small fat cells produce a "good face" hormone called adiponectin, which makes the liver and muscles sensitive to hormonal insulin, in the process becoming less susceptible to diabetes and heart disease.
When people become fat, the production of adiponectin decreases or shuts off, placing them for disease, according to fried and others.
Subcutaneous fat is found directly under the skin. It is fat that is measured using skin fold tweezers to estimate your total body fat.
In terms of general health, subcutaneous fat in thighs and buttocks, for example, may not be so bad and can have some potential benefits, says Ciay. "It may not cause so many problems" like other fat types, specifically deeper and visceral fat, he says.
But subcutaneous fat cells in the belly can be another story, says fried. There is emerging evidence that the danger of large bellies does not only reside in deep visceral fat, but also subcutaneous fat.
involves visceral or "deep" fat around the internal organs and spells problems for your health. How do you know if you have? "If you have a big waist or belly, of course you have visceral fat," says Whitmer. Visceral fat transmits your risk to diabetes, heart disease, stroke and even dementia.
Visceral fat is believed to play a greater role in insulin resistance - which increases the risk of diabetes - than another fat, Whitmer WebMD account. It is not clear why, but could explain or explain partially why visceral fat is a health risk.Whitmer investigated the connection between visceral fat and dementia. In one study, she evaluated the records of more than 6,500 members of the Permanent Kaiser of Northern California, a large health maintenance organization, for an average of 36 years, from the time they were in the 1970s.
.The records included details about height, weight and belly diameter - a reflection of the amount of visceral fat. Those with the largest bellies had a greater risk of dementia than those with smaller bellies. The link was true, even for people with excessive belly fat, but overall the normal weight.
She does not know why belly fat and dementia are linked, but speculates that substances like leptin, a hormone released by belly fat, can have some adverse effect on the brain. Leptin plays a role in the appetite regulation, but also in learning and memory.
Belly fat got a well-deserved reputation as an unhealthy fat. "Understand that belly fat is viscerous and subcutaneous," says Kristen Gill Hairston, MH, MPH, Medicine Assistant Professor at Wake Forest University School of Medicine, Winston-Salem, NC, we still do not have a perfect way to determine which [ of belly fat] is subcutaneous or visceral, except for computed tomography, but this is not economical. "
But if you have an oversize belly, find out how much visceral it is and how much subcutaneous is not as important as recognizing a great belly is unhealthy, she says. How big is too big? Women with a waist circumference more than 35 inches and men with a waist circumference over 40 inches are at increased risk of disease.
Abdominal fat is seen as a greater risk of health than hip or thigh, whitmer and other experts say. And this could mean having a worse effect on insulin resistance, boosting the risk of diabetes, and a worse effect on lipids in the blood, boosting the risks of heart and stroke.
So when you lose weight, what kind or kind of fat did you pour out? "You're losing white fat", fried webmd account. "People tend to lose evenly."
The results change a little, however, if you add exercises to your reduction of calories, it says. "If you exercise more diet, you will tend to lose a slightly more visceral fat of your belly."
"We are in an exciting point in science," says Whitmer, echoing the entrance of other scientists in the field.
Whitmer and others expect more discoveries on fat of all kinds to be made in the near future.
