AMRA Medical's Analysis Evaluates Liraglutide's Effect on Obesity

Research shows that liraglutide, a medication typically used for diabetes, can also reduce muscle fat in people with obesity who are at high risk of cardiovascular disease. This finding comes from a study involving 128 adults without diabetes who received either liraglutide or a placebo over a 40-week period, in addition to lifestyle changes.

The study was carried out by AMRA Medical, a company specializing in body composition analysis through MRI technology, in collaboration with the University of Texas Southwestern and University Hospital Cleveland. Researchers aimed to examine how liraglutide influences muscle composition, particularly muscle fat infiltration in the thigh.

At the start of the study, participants had an average muscle fat infiltration of 7.8%. Those who were administered liraglutide showed a significant reduction in muscle fat compared to those who received a placebo. Specifically, the muscle fat infiltration decreased by an average of 2.87% among the liraglutide group, while it barely changed in the placebo group. In absolute terms, the reduction was -0.23% for the liraglutide group compared to a negligible 0.01% increase in the placebo group.

In addition to measuring muscle fat, the study also assessed muscle volume using AMRA's proprietary muscle volume z-score. This metric did not show a significant difference between the liraglutide and placebo groups when adjusted for baseline muscle volume. However, the proportion of participants with adverse muscle composition, defined as high muscle fat infiltration and low muscle volume, decreased from 11.0% to 8.2% in the liraglutide group, while remaining unchanged in the placebo group.

These findings underscore the potential benefits of liraglutide in improving muscle composition in people with obesity, aside from its known advantages in weight loss and diabetes management. The improvement in muscle fat infiltration could have positive implications for cardiometabolic health, though further research is needed to fully understand this relationship.

As obesity rates continue to rise globally, the importance of effective treatments becomes increasingly critical. Pharmacological interventions like liraglutide are becoming more integrated into obesity management strategies, traditionally dominated by lifestyle modifications. Understanding the broader impacts of such treatments, particularly on muscle health, is essential to ensuring comprehensive patient care.

AMRA Medical is at the forefront of this research, using their advanced MRI-based body composition analysis to generate normative data on how GLP-1 agonists like liraglutide affect muscle composition. Their technology provides detailed insights into fat and muscle biomarkers, facilitating better clinical and research outcomes.

AMRA recently shared related findings at the European Association for the Study of Diabetes Annual Meeting. They presented data showing that another GLP-1 agonist, tirzepatide, led to significant weight loss without negatively impacting muscle composition.

AMRA Medical continues to push the boundaries of body composition research, offering tools that enhance the understanding and treatment of metabolic diseases, including obesity. Their work is pivotal in shaping future therapeutic approaches and ensuring that treatments do not inadvertently harm muscle health.
