ISTOCK, STOCKVISUALAn impaired ability to break down fats is associated with later weight gain and metabolic disorders in women, according to a study published today (May 31) in Cell Metabolism. Researchers at the Karolinska Institute found that low levels of a biochemical process known as hormone-stimulated lipolysis were linked to increased weight and complications such as type 2 diabetes 13 years later, offering the possibility of a diagnostic test for obesity risk as well as improved interventions.
“This information could be used by clinicians to determine who would benefit the most from intensified lifestyle interventions such as physical activity, which enhances hormone-stimulated lipolysis and may therefore prevent fat accumulation and metabolic disturbances,” study coauthor Mikael Ryden says in a statement.
Ryden and his colleagues collected fat biopsies from 89 women, and followed up after an average of 13 years. The team found that, compared with women who went on to maintain a stable weight over that period, women who gained weight over the course of the study showed relatively low levels of hormone-stimulated lipolysis and low expression of genes involved in regulating fat breakdown.
The researchers also developed an algorithm to estimate the rates of hormone-stimulated lipolysis on the basis of biomarkers ...
