Key Takeaways
Protein Requirements After 60
Protein requirements after 60 refer to the amount of dietary protein older adults need each day to preserve muscle mass, support immune function, and maintain overall physical resilience. These needs are measurably higher than the general adult recommendation, largely because aging reduces the body's efficiency at using protein to build and repair muscle tissue.
This reduced efficiency is linked to a phenomenon called "anabolic resistance" — the blunted muscle protein synthesis response to protein intake and exercise that occurs with advancing age.
Why Protein Needs Rise With Age
Most people assume nutritional needs stay roughly stable through adulthood. For protein, that assumption doesn't hold after 60. The body's ability to convert dietary protein into functional muscle tissue becomes less efficient over time — a process researchers call anabolic resistance. The result: older adults need to consume more protein just to achieve the same muscle-building response a younger person gets from a smaller amount.
At the same time, the consequences of getting too little protein grow more serious. Sarcopenia — the gradual loss of muscle mass and strength that accompanies aging — accelerates from the sixth decade onward. Left unchecked, it contributes to falls, fractures, slower recovery from illness, and diminished daily function. Protein is one of the most powerful dietary levers available to slow that decline.

1.0–1.2 g/kg
Recommended daily protein for adults over 60
Supported by the PROT-AGE Study Group and multiple aging nutrition researchers, compared to the standard RDA of 0.8 g/kg.
~3–8%
Muscle mass lost per decade after age 30
According to research published in the Journal of Cachexia, Sarcopenia and Muscle, the rate of loss accelerates significantly after age 60.
25–30 g
Optimal protein per meal to stimulate muscle synthesis
Research in older adults suggests this per-meal threshold is needed to overcome anabolic resistance and maximize muscle protein synthesis.
What the Evidence Actually Recommends
The standard Recommended Dietary Allowance (RDA) for protein — 0.8 grams per kilogram of body weight per day — was established for the general adult population and does not specifically account for the physiological changes of aging. A growing body of research, including guidance from groups such as the PROT-AGE Study Group, suggests older adults are better served by a target closer to 1.0–1.2 g/kg per day, with higher amounts potentially warranted for those who are very physically active or managing illness or injury.
Equally important is how that protein is distributed. Studies suggest that spreading intake across three or more meals — aiming for roughly 25–30 grams per meal — produces a stronger muscle protein synthesis response than eating the same total amount skewed toward one large meal. This is particularly relevant because dinner tends to be the protein-heavy meal for many Americans, while breakfast and lunch often fall short.
Build Protein Into Every Meal
Rather than relying on one protein-heavy dinner, aim to include a meaningful protein source at breakfast, lunch, and dinner. Eggs, Greek yogurt, cottage cheese, legumes, and fish are practical options that fit easily into most meal styles. If appetite is a challenge — which becomes more common after age 65 — see our guidance on eating well when appetite decreases.
Best Food Sources for Older Adults
Both animal and plant proteins can support muscle health in later life, though they differ in amino acid profiles and digestibility. Animal sources — eggs, fish, poultry, lean meat, Greek yogurt, and cottage cheese — provide complete proteins rich in leucine, the amino acid most directly linked to triggering muscle protein synthesis.
Plant sources including tofu, edamame, lentils, chickpeas, quinoa, and hemp seeds can absolutely meet protein needs, but typically require greater volume and thoughtful food combination to deliver equivalent amino acid profiles. This is worth noting — not as a reason to avoid plant protein, but as a practical consideration for meal planning. Our article on common protein myths examines the plant-versus-animal debate in more detail.
Protein and Exercise: A Necessary Partnership
Protein intake doesn't work in isolation. Resistance exercise — lifting weights, using resistance bands, or doing bodyweight movements — is the signal that tells muscles to use available protein for growth and repair. Without that stimulus, even generous protein intake produces limited muscle-preserving benefit.
The good news is that older muscles retain meaningful capacity to respond to resistance training. Combining adequate protein intake with regular strength work produces significantly better outcomes for muscle mass and functional strength than either strategy alone. For a closer look at how to approach exercise in later life, see our overview of strength training after 60.
It's also worth noting that protein isn't the only nutrient older adults commonly fall short on. Our article on under-consumed nutrients in later life covers the broader picture, including vitamin D and B12 — both of which interact with muscle and bone health.
“Protein is not just about building muscle in young athletes. For older adults, adequate protein intake is a foundational strategy for maintaining independence, resilience, and quality of life.”
