Prevent Muscle Loss After 60

In your 60s, gradual age-related change can be compounded by dieting, surgery, illness or an inactive recovery. Humanic Blue is looking at those vulnerable moments to understand what the evidence says about preserving strength and independence—and what that can tell us about living longer and better.

A 2025 analysis of trials in adults 60 and older found that resistance training—exercise against a load, such as weights—improved lean mass, muscle size and leg strength. Lean mass is tissue other than fat; it is not a measurement of muscle alone. The evidence was uncertain, particularly for adults with physical impairments.

The current US Physical Activity Guidelines recommend muscle-strengthening activity at least twice a week for adults, plus balance activity for older adults; this is population guidance, and CDC guidance says activity should fit a person’s abilities and conditions. During intentional weight loss in the 26-week LITOE trial, resistance or combined training preserved more lean mass than aerobic training alone in adults 65 and older with obesity and mild-to-moderate frailty. That trial does not establish a plan for everyone.

After serious illness or hospitalization, a treating clinician or physical therapist can assess when and how to restore mobility and strength. Grip strength and a test of standing up from a chair five times can help clinicians identify possible sarcopenia, a muscle condition involving low strength and reduced muscle quantity or quality. Neither test is a stand-alone diagnosis. Protein targets are not one-size-fits-all, especially with kidney disease. These findings concern function and independence; whether they extend lifespan has not been tested directly.

Does resistance training still work after 60?

A 2025 review comparing resistance-training trials found gains in lean mass, muscle size and leg strength in adults aged 60 and older. Programs with smaller and larger amounts of training both produced gains compared with no exercise. The reviewers had low confidence in the lean-mass and muscle-growth estimates and very low confidence in the strength estimates. Evidence in physically impaired adults was limited, so these averages cannot predict one person’s response.

Current US Physical Activity Guidelines recommend that adults do muscle-strengthening activities at least two days a week and 150–300 minutes of moderate-intensity aerobic activity. Older adults should also include balance work. The guideline is a population-level minimum, not an individualized rehabilitation plan.

Threat 1: Losing weight

Weight loss is common advice in the 60s, for blood sugar, joints or heart health. Some of what’s lost is muscle and bone.

The LITOE trial, published in the New England Journal of Medicine in 2017, tested exercise modes during intentional weight loss. Sedentary adults 65 and older with obesity and mild-to-moderate frailty were randomly assigned to a control group or to a weight-management diet plus aerobic, resistance or combined training. The supervised trial tested a particular diet and exercise program, not a general prescription for everyone losing weight.

All three exercise groups lost about 9% of body weight, but what happened underneath that number differed. The aerobic group lost more lean mass and hip bone density than the resistance and combined groups. Strength improved much more with resistance and combined training, while the combined group had the largest improvement on the trial’s overall physical-function test. The full results table is in Extra Insights. Exercise-related events included falls, joint or back pain, atrial fibrillation (an irregular heart rhythm) and shoulder injury. The trial was funded by the National Institutes of Health and reported no commercial support.

A 2026 review comparing trials placed that result in a wider evidence base in community-dwelling older adults with obesity. Programs combining nutrition, exercise and behavior change improved performance on groups of physical-function tests, with high confidence in that finding. Effects on fat-free tissue and bone density were very uncertain. Evidence in frail adults, people 75 and older and over the longer term remained limited.

Weight loss with GLP-1 medicines raises the same question, as covered in Prevent Muscle Loss After 40.

Which outcomes belong beside weight change when interpreting the LITOE trial?

How can hospitalization affect independence?

A 2026 review of hospital studies estimated that 27% of older inpatients lost independence in daily activities around their hospital stay. But individual studies reported rates from 5% to 57%. The overall estimate describes a pattern across hospitals; it is not a forecast for an individual patient.

The decline reflects illness, baseline vulnerability and hospital processes—not bed rest alone. A 2024 risk-factor meta-analysis identified frailty, poor physical function, immobility and delirium (sudden confusion) among confirmed risk factors, along with age, the number and severity of other illnesses, dementia and length of stay. Experimental bed-rest findings are covered in Prevent Muscle Loss After 50, but those healthy-volunteer studies do not reproduce the physiology or care of acute illness.

Threat 3: Not noticing

Muscle loss can be missed until everyday tasks get harder. The European Working Group on Sarcopenia in Older People uses low strength—measured with grip strength or a five-rise chair test—to identify probable sarcopenia. Low muscle quantity or quality confirms the diagnosis; poor physical performance indicates severe sarcopenia. Those are consensus criteria, not evidence that annual self-testing prevents disability. Grip strength is covered in Grip Strength and Longevity, and unintended weight loss and slowing are discussed in Can Frailty Be Reversed?.

At 65, many people join Medicare. According to Medicare.gov, its yearly Wellness visit can include an optional assessment of physical-activity and nutrition risks. That’s one place to raise strength concerns, although the visit is not a routine physical examination or a guaranteed sarcopenia screen.

What distinguishes a low-strength screening result from a complete sarcopenia assessment?

Do protein needs change after 65?

Protein guidance does not change automatically at 60. The National Academies’ recommended dietary allowance (RDA) for adults remains 0.8 grams of protein per kilogram of body weight per day, while the 2025–2030 US Dietary Guidelines use a general target of 1.2–1.6 grams per kilogram of body weight per day. The shorthand g/kg/day means grams per kilogram of body weight each day. A separate 2013 PROT-AGE expert consensus proposed 1.0–1.2 g/kg/day for generally healthy people older than 65 and 1.2–1.5 g/kg/day for many with acute or chronic illness. Those standards serve different purposes, and the consensus is not proof that one target fits everyone.

Kidney disease changes the discussion. Current KDIGO guidance suggests 0.8 g/kg/day for adults with chronic kidney disease stages G3–G5 who are not on dialysis. These stages range from mildly to moderately reduced kidney function through kidney failure. The guideline advises avoiding intake above 1.3 g/kg/day when progression is a concern. It also cautions against low-protein diets in people whose metabolism is unstable, such as during serious illness. A clinician or renal dietitian should reconcile kidney, nutrition and muscle risks. The LITOE diet’s approximately 1 g/kg/day applies only to that trial.
