Lifting ranks first when older adults fight muscle loss and fat together

Sarcopenic obesity, the combination of low muscle strength and excess body fat, is highly prevalent among older adults and linked to adverse clinical outcomes. It is a harder problem than simple weight loss, because shedding fat without protecting muscle risks deepening the weakness that makes the condition dangerous in the first place. Options on offer range from resistance training and aerobic work to multicomponent programmes, with or without nutritional supplementation or high-protein intake, yet direct comparisons between them have been scarce. This review set out to rank the strategies against each other rather than judging each in isolation.

Researchers searched PubMed, Embase, the Cochrane Library and Web of Science from inception to November 2025, without language restrictions. They identified 24 randomised controlled trials involving 1,298 older adults with sarcopenic obesity, covering nine distinct exercise and nutrition strategies. A network meta-analysis then compared every strategy against usual care and against each other on body mass index, handgrip strength, fat mass, percentage body fat and skeletal muscle index. Risk of bias was assessed with an established Cochrane tool, the certainty of evidence was formally graded, and the protocol was registered in advance.

Resistance training ranked first for handgrip strength, improving it by a mean of 3.96 against usual care, and was the only approach to significantly cut fat mass, by 2.30 on average. Multicomponent training was the only strategy to significantly reduce body mass index, by 1.08, and ranked top for percentage body fat with a 3.53 point drop; resistance training also lowered body fat percentage significantly. No intervention significantly improved skeletal muscle index, though multicomponent training combined with nutritional supplementation ranked relatively favourably on that measure. Consistency testing, sensitivity analyses and funnel plots suggested the network held together, the findings were robust and publication bias was unlikely.

The result fits the broader picture that exercise is the backbone of managing sarcopenic obesity, but it sharpens that picture by ranking the options directly against one another. Resistance training emerging on top for strength and fat measures echoes what individual trials have suggested, while the strong showing of multicomponent programmes on BMI and body fat percentage adds useful nuance. The failure of any strategy to move skeletal muscle index is the notable gap, since that index sits at the heart of the sarcopenia side of the diagnosis. The authors call for larger, longer trials with direct head-to-head comparisons to settle which combinations work best over time.

For an older adult, or anyone helping one train, the message is that structured exercise carries the load here and the type of exercise matters. This is a reason to think of resistance work as the priority when grip strength and fat loss are the goals, with mixed programmes a credible alternative when overall body composition is the focus. It is equally a reason for measured expectations about supplements, which did not clearly add benefit in these comparisons. And since nothing reliably rebuilt the muscle index itself, quick fixes look unlikely; this is a long game.
