Study: Yo-yo dieting could increase risk of death

New Korean research has found that weight cycling, which is a term for constantly losing and gaining weight, usually due to diet, is associated with a higher risk of death.

Carried out by researchers at Seoul National University (SNU) College of Medicine, Seoul National University Bundang Hospital and Ajou University School of Medicine, Korea, the new study looked at 3,678 Korean men and women and followed them for a period of 16 years.

During this time, the researchers collected data on the participants’ body weight and any health-related outcomes every two years, to see if weight had any effect on the incidence of diabetes and cardiovascular events.

The findings, published in the Endocrine Society’s Journal of Clinical Endocrinology & Metabolism, showed that participants whose weight fluctuate the most were more likely to be obese, have higher blood pressure, and higher HbA1c levels, which are associated with an increased risk of diabetes, at the start of the study than those whose weight didn’t fluctuate as much.

In addition, the researchers also found that weight cycling was associated with a higher risk of death.
