A new study by an Israeli-led team of researchers suggested that reducing liver fat rather than just losing weight is key to minimizing the long-term health risks tied to obesity.
The study, published in the Journal of Hepatology, used magnetic resource imaging (MRI) to track different types of fat in the body, while also examining how different types of diets affected fat deposits over time, according to a press release this week from Ben-Gurion University of the Negev.
The research team recorded a 30 percent drop in the levels of liver fat in those on the Mediterranean diet, which it said was key to curbing obesity-related health risks, such as diabetes and cardiovascular disease. The study also recorded a decrease of 11% in fat around the heart and a 25% reduction in visceral fat, as well as moderate weight loss.
The study included 300 overweight people who were put on the two type different diets and tracked their health changes over a period of 18 months. Full-body MRIs were used to check fat levels throughout the body before, during and after the study.
Ben-Gurion University Professor Iris Shai, who led the team of scientists that included researchers from Harvard and Germany’s Leipzig University, said the study’s findings could help shape medical protocols by tailoring them to address different types of fat.
“Healthy nutrition, while also maintaining consistent, moderate weight loss, has a much more dramatic impact on levels of body fat related to diabetes, heart disease and cardio-vascular disease than we previously thought,” she said in a statement from the university.
A researcher from Soroka University Medical Center, which along with the Negev Nuclear Research Center also assisted in the study, said the findings gave further backing to the effectiveness of MRI technology in measuring liver fat levels.
