The standard protein recommendation most people grew up hearing is 0.8 grams per kilogram of body weight. This is based on the minimum needed to prevent deficiency in young, sedentary adults. It’s not enough for most adults over 50, and following it can quietly accelerate age-related muscle loss.
Your Target: 1.0–1.2 g/kg Minimum, Often Higher
For adults 50 and older, aim for at least 1.0–1.2 grams per kilogram of body weight per day. If you’re also managing a chronic condition, recovering from illness or surgery, or actively strength training, that target often climbs to 1.2–1.6 g/kg, similar to recommendations for younger active adults.
In calorie-percentage terms, this generally works out to 20–30% of total daily calories, with older adults typically doing best toward the middle-to-upper end of that range.
Why the Recommendation Changes With Age
Starting around age 30, and accelerating after 50, the body naturally loses muscle mass over time — a process called sarcopenia. Aging muscle also becomes less responsive to protein’s signal to build and repair tissue. In practice, this means older adults often need more protein per meal than younger adults to trigger the same muscle-preserving response, not less.
Left unaddressed, this muscle loss contributes to reduced strength, slower recovery from illness or injury, higher fall risk, and loss of independence — all of which are largely preventable with adequate protein intake and resistance exercise.
How to Hit Your Target Without Overhauling Everything
-
- Aim for 25–30+ grams of protein for every meal. Because of anabolic resistance, spreading adequate protein across three meals tends to work better than front- or back-loading it into one large meal.
- Don’t skip breakfast protein. Breakfast is often the lowest-protein meal of the day by habit (toast, cereal, coffee). Adding eggs, Greek yogurt, or a protein shake closes that gap easily.
- Pair protein intake with resistance training, even at a light level. Bodyweight exercises, resistance bands, or light weights 2–3x per week significantly amplify what protein alone can do for muscle maintenance.
- Watch for reduced appetite. Appetite naturally declines with age for many people, which can make hitting protein targets harder even with good intentions — smaller, protein-dense meals and snacks throughout the day can help close the gap.
The Bottom Line
The protein recommendation you may have learned decades ago likely isn’t enough for you now. Aim for 1.0–1.2 g/kg at minimum, higher if you’re active or managing a health condition, spread across meals in servings of 25–30+ grams, and paired with resistance exercise for the biggest protective effect against age-related muscle loss.
