" This illustrates that you ca n’t have one sweeping skirmish to categorize all obese someone , " said study researcher Jennifer Kuk , an assistant professor at York University in Toronto . People need to see at whether they have additional jeopardy factor indicating poor health to determine whether they should recede system of weights , Kuk say .
In fact , the results suggest that " yo - yo diet , " in which individuals misplace weight but gain it back later on , might be more unhealthful for some corpulent people than simply maintaining their weight , Kuk said . Participants in the study who lose the most weight over their life-time , but had n’t necessarily hold the weighting off , were more likely to have extra wellness complicatedness from their obesity than those who lost less weighting .
The researchers are working to develop a scaling organization that could help Dr. find which obese patient would do good from weight loss . The report was published today ( Aug. 15 ) in the journal Applied Physiology , Nutrition and Metabolism .
Obesity and mortality
Kuk and colleague read the Edmonton Obesity Staging System ( EOSS ) , which classifies rotund individuals into five category based on their health risk of exposure . Obese individuals who have no obesity - associated diseases , such as diabetes , high blood pressure , back pain or depression , are classified as stage 0 . The more peril component you have in accession to corpulency , the higher on the scale you rank .
The researchers canvas data from about 6,000 obese , center - age Americans who attended a health clinic in Dallas between 1987 and 2001 . The participants were assessed by a physician for health complications . They also answered questions about their strong-arm activity stratum , fruit and vegetable intake and pastweight loss efforts .
After 16 years , mass classify as Eos stage 2 or 3 were about 1.6 times more likely to have died of any cause , and about 2 times more probable to have died of cardiovascular disease as normal - weight individuals .
However , those assort as stage 0 or 1 were no more likely to have go bad than those of normal weighting . In fact , degree 0 or 1 participants were less likely to snuff it from cardiovascular disease than mass of normal weight , the researchers aver .
Stage 0 and 1 individual were more potential to be physically active andeat more fruits and vegetablesthan those sort out as stage 2 or 3 . microscope stage 0 or 1 participants were also less likely to report engaging in weight loss pattern .
Dieting may be risky to your health if you regain the weight you ’ve fall back , Kuk said . Most people who lose weight will at last put the pounds back on , and may regain more than they lost , she said .
Obese but healthy
It ’s " absolutely " potential for people to be overweight orobese and sound , said Dr. Pieter Cohen , an assistant professor of medicine at Harvard Medical School and a general internist at Cambridge Health Alliance . However , the new bailiwick is just a " small piece in a tumid teaser , " to endeavor to find out which someone will do good from weight unit loss , Cohen say .
Even if we identify somebody at high hazard for complication from obesity , it ’s unclear whether losing weightiness will quash their peril of dying , Cohen said . To more clearly reply the question , researcher should randomly assign corpulent masses to either lose weight or maintain their weight and practise a healthy life-style , to see which chemical group sees more betterment in health , Cohen said .
The findings do not give obese mortal a " free license " to advance weight , Kuk said . Rather , the written report suggest that preserve exercising weight , eating right and exercising may , in the long ladder , be better than trying to lose weight , Kuk said .
conk it on : Some rotund individuals may be good off maintain their weightiness and practicing a healthy life style than attempting to lose weight , a study suggests .
