Sarcopenic Obesity Increases Mortality by 83%
A 12-year follow-up study has found that the combination of abdominal fat and low muscle mass – sarcopenic obesity – increases the risk of all-cause mortality by 83% in people over 50. Hungary is particularly affected, grappling with one of the highest obesity rates in Europe.
Deadly Combination: Abdominal Fat and Muscle Loss
A large-scale study by a Brazilian-British research team has revealed that the co-occurrence of abdominal obesity and low muscle mass – known as sarcopenic obesity – increases the risk of all-cause mortality by 83% in adults over 50. Researchers from the Federal University of São Carlos and University College London reached this conclusion after a 12-year follow-up of 5,440 participants, with their findings published in the journal Aging Clinical and Experimental Research.
Sarcopenic obesity triggers a self-destructive vicious cycle: adipose tissue produces inflammatory substances that accelerate muscle breakdown, while the decrease in muscle mass slows down metabolism, promoting further fat accumulation. This combination is far more dangerous than either condition alone.
BMI Doesn't Detect It
One of the most important messages of the research is that the traditional body mass index (BMI) is unable to detect sarcopenic obesity. A person with a normal BMI can still be affected if their body composition is unfavorable – with a lot of abdominal fat and little muscle mass. However, the researchers have shown that the condition can be screened with simple clinical measurements: measuring waist circumference (risky above 102 cm for men and 88 cm for women) and estimating muscle mass index are possible without expensive imaging tests.
A 2025 systematic review and meta-analysis, which aggregated data from 578,408 participants, confirmed that sarcopenic obesity increases the risk of cardiovascular disease by 95% and raises cardiovascular mortality by 64%.
Hungary: Particularly at Risk
The discovery is particularly worrying for Hungary. The country is one of the most obese nations in Europe: more than half of the adult population is overweight or obese, and according to OECD data, it is among the leaders worldwide. The situation is exacerbated by the fact that 56% of Hungarians never engage in sports in their free time – well above the EU average – and physical activity is mostly limited to work and housework, not targeted exercise.
The combination of an aging population, a sedentary lifestyle, and a high obesity rate creates a perfect breeding ground for the spread of sarcopenic obesity. The average life expectancy at birth in Hungary is almost 5 years lower than the EU average, in which obesity-related chronic diseases play a decisive role.
The Key to Prevention: Exercise and Protein
The literature is clear: the most effective prevention and treatment for sarcopenic obesity is resistance (weight) training 2-3 times a week, combined with aerobic exercise. The European Society for Clinical Nutrition and Metabolism (ESPEN) recommends that older adults consume at least 1.0–1.2 grams of protein per kilogram of body weight per day, with 25–30 grams of high-quality protein per meal – significantly more than the amount typically consumed in the Hungarian diet.
The researchers emphasize that early detection and treatment of sarcopenic obesity can not only save lives but also reduce the burden on the healthcare system. In Hungary, this would require a transformation of prevention programs: BMI-based screening alone is insufficient, and body composition analysis and muscle strength measurement should become part of primary care.
