Women who regain weight straight after dieting display a change in a particular protein in their body, prompting hopes that a test could be developed in the future to identify those who are at risk of regaining weight.
Recent studies have shown that more than 80 percent of dieters suffer from the "yo yo effect" and regain weight within a year of dieting. Researchers from the Maastricht University's Department of Human Biology analyzed more than 100 women aged between 20 to 45 years with half of them managing to avoid regaining their weight after dieting.
Researchers found that those who gained weight quickly after dieting displayed higher concentration a protein, known as angiotensin I converting enzyme (ACE), when they were dieting.
"We do not yet have an explanation for the results, but it does appear that it should be possible within a few years to use this finding to develop a test to show who is at high risk of putting weight back on after a diet", lead researcher Edwin Mariman said in the study which has been published in the online scientific journal PloS ONE.
