Ben je te dik? Deel je taille-omvang door je lengte, en je weet het
Als je wilt weten of je lichaamsvet moet verliezen, deel dan de omvang van je taille (in centimeters) door je lichaamslengte (ook in centimeters). De uitkomst van die rekensom is veelzeggender dan de good old BMI. Dat schrijven Engelse onderzoekers, verbonden aan Leeds Beckett University, in PLoS One.
Studie
Resultaten
Als bij mannen de taille/lengte verhouding boven de 0.53 komt, zijn ze obees. Bij vrouwen is dat 0.54. Als bij mannen en vrouwen de taille/lengte-verhouding boven de 0.59 komt, dan hebben ze teveel buikvet.
Misschien ook wel leuk om te weten: tijdens de studie gaf de BMI-methode bij 14 procent proefpersonen aan dat het tijd was om lichaamsvet kwijt te raken. Bij de taille/lengte-verhouding gebeurde dat bij 37 procent van de proefpersonen.
Conclusie
"This is most definitely the case when people have a 'normal' BMI but high abdominal fat that is often dismissed. Whole-body fat percentage, and specifically visceral adipose tissue mass, are associated with health conditions including insulin resistance, type 2 diabetes and cardiovascular disease, but are not fully accounted for through BMI evaluation."
"Carrying fat around the abdominal area has been shown to be an independent predictor of all-cause mortality in men and women. Put simply, it is more important, especially for cardio-metabolic conditions, that your belt notch goes down than the reading on the scales."
"Our waist-to-height ratio cut-points align broadly to current guidelines that adults and children should keep their waist circumference to less than half their height. In current clinical practice, it is common to calculate BMI for an indication of whole-body fat and waist circumference for abdominal obesity."
"Our research has shown that waist-to-height ratio is a more accurate alternative to these two measures and also a more time-efficient measure. By introducing this alternative, and more accurate, measure into clinical settings, more men and women would potentially be referred to programmes, such as weight management, to receive help in improving their health."
