Aroundone - thirdof all teenager in the UK are clinically fleshy or obese , and it ’s apace becoming one of the large health challenge of our time . Nowresearchers may have identifiedone of the driving forces behind this epidemic , as they have identify something surprising : The number of calories sting by teen as they hit puberty dramatically strike down , go against what we thought we knew about teenaged development .
The bulk of the kilogram calorie we burn are spend maintaining our consistency , from keep organs functioning to warm up our blood , something that is known as our resting rate . It now seems that after the age of around 10 years honest-to-goodness , the number of kilocalorie being consume by adolescent ' trunk sharp drops by around a full 25 percentage . In real full term , this equates to rough 500 small calorie , a not insignificant amount .
The findings by the research groupare reasonably unexpected . With the massive outgrowth squirt have by most adolescents in their teenage class , most presumed that the turn of large calorie burnt would get up to account for this , but that is clearly not what is going on . After the drop at around 10 years sure-enough , the number of take a breather calories burnt does n’t then increase until the stripling hits around 16 years of eld . While the ground behind this sudden drop cloth in the burn of calories during puberty are still unknown , it may have deep evolutionary roots .
“ We can only speculate as to why , but it could be a result of an evolutionary trait to hold open nutritionist’s calorie for increment that may now contribute to a grave emanation in adolescent obesity in cultures where food is in abundance,”explainsProfessor Terence Wilkin , who co - author the paper published inThe International Journal of Obesity . “ It could be that we have evolve to preserve calories to see to it we have enough to substantiate change in the consistency during puberty , but now we know they have sufficient calories each day , the drop in spend means excess free weight profit . ”
But that was n’t all . The surprising pearl in calories seen in the adolescent was also coupled with a drop in the amount of workout that the adolescents take on , a switching that was particularly pronounced in teenage girls . Both of these changes , the authors argue , are sufficient to excuse why there is a sudden increase in the pace of juvenile corpulency when immature hoi polloi hit pubescence , something that had been observed before but never fully explained .
These resultant could have a significant impact on the health and advice given to young teenagers just hit puberty , in an effort to assay and turn off the soaring corpulency rates seen in many parts of the world .
