Obesity often brings with it a host of health problems , such ashigh lineage pressure , diabetes and risky cholesterol levels . But a lucky few appear to buck the style : They are obese , and yet do n’t have any of these typical jeopardy factor for gist disease or diabetes , a new report finds .
research worker examine information from about 1.3 million U.S. grownup who were either fleshy or rotund . None had antecedently been diagnose withdiabetes . The researchers looked to see whether these participants had any of four common danger factor for spunk disease and diabetes : High blood pressure , high levels of adipose tissue in the stock , low-down levels of " good " cholesterin or elevated stemma shekels levels .
Among those who were obese , 10 percent did not have any of these four peril gene .
It ’s not exonerated why some people with obesity are able to obviate these problems . In the past , investigator have dub this radical the " metabolically healthy obese . "
However , people who fall down into this group may still not be totally healthy , said study investigator Gregory Nichols , a aged investigator at Kaiser Permanente Center for Health Research in Portland . Obesity also increases the risk of other condition , such as cancer , joint problems and kidney disease , he order .
" They might be metabolically healthy , but that does not necessarily mean they are salubrious overall , " Nichols tell Live Science . What ’s more , although these participant were barren of metabolic risk factor at the prison term of the written report , they could soon develop them in the coming years , he said . Some previous study have found that even " metabolically healthy " obese the great unwashed are at higher peril of developingtype 2 diabetes , liken with people of normal weight .
Thus , people who are obese should still aspire to turn a loss system of weights , even if they seem otherwise goodly , Nichols said . " weight unit release could improve other types of wellness [ job ] , and might reduce the likelihood of developing cardiometabolic risk divisor , " he enunciate .

For the study , the researcher analyzed electronic health forethought records from members of four health care system that together serve 12 million people in 11 U.S. states and Washington , D.C. They defined being overweight as having a body mass index ( BMI ) of 25.0 to 29.9.Obesitywas define as get a BMI of 30 or more , while diseased obesity was a BMI of 40 or more .
They find out that 18.6 percent of the mass who were overweight did not have any of the four metabolic hazard factors , and 9.6 per centum of those who were weighty did not have any of the four . attend at only those who were morbidly obese , they find oneself that 5.8 pct did not have any of the four risk factor .
Being " metabolically " good for you was more common among those who were young — about 30 percentage of all adult ages 20 to 34 in the cogitation did not have any of the four metabolic jeopardy factors , compared with just 6.3 per centum of those ages 65 to 79 .
Several factors could explain why some heavy people and some corpulent people remain metabolically healthy . " Diet and exercise almost sure act as a role , " Nichols tell . However , the young study did not assess these factors .
In addition , the statistical distribution of a soul ’s fatty tissue can also affect their danger of cardiovascular disease , with fertile store in the belly area ( visceral fat ) position a peachy risk to health than fat happen just beneath the skin ( subcutaneous fat ) in other parts of the body . Some former cogitation have found that obese citizenry who are metabolically healthy have less visceral fat than corpulent masses who are n’t metabolically healthy . However , a individual ’s BMI measuring , used in this new subject field , can not key between visceral adipose tissue and hypodermic fat .
at last , future study are needed to espouse metabolically intelligent rotund people forward in fourth dimension , to see if they continue metabolically healthy over a long time period , or even a life-time , Nichols said . Such study could determine whether metabolically healthy obesity " is even a real affair , or simply a matter of timing , " Nichols say .
In addition , studies should front at the ordination in which people develop metabolic hazard factors , and whether this order dissemble their risk of develop subsequent heart disease and diabetes , he suppose .
The study was published March 9 in the daybook Preventing Chronic Disease .
