Nutrition Experts Urge 20-30 Grams of Protein Per Meal for Healthy Aging

Q: Your body resists building muscle after 40. How much more protein do experts now say you need at every single meal?

Experts now generally say adults over 40 should aim for about 25 to 35 grams of protein at each meal, with some research suggesting closer to 35 to 40 grams may be needed in later years to overcome age-related “anabolic resistance.” That is higher than the baseline advice in the news story, where dietitian Joan Salge Blake recommended 20 to 30 grams per meal for satiety and steady muscle synthesis. The added reporting shows why the target rises with age: after 40, muscle becomes less responsive to protein, so the body needs a stronger amino-acid signal at each meal to stimulate muscle protein synthesis. In practical terms, many experts now treat roughly 30 grams per meal as a useful target for midlife and older adults, especially if preserving muscle is the goal. Some sources cited in the background put the effective range at 25 to 40 grams per meal, but the most consistent takeaway is that 25 to 35 grams per meal is the new benchmark for people whose bodies are less efficient at building muscle. Experts also stress that timing matters. Spreading protein evenly across breakfast, lunch and dinner works better than eating most of it at night, because the body does not store protein the way it stores fat or carbohydrates. Pairing that intake with resistance exercise is considered the most effective strategy for maintaining strength and healthy aging.

Nutrition experts say two simple daily habits—drinking water early and eating protein at every meal—can help support metabolism, muscle mass and long-term health as people age.
20 to 30 grams of protein per meal can sustain muscle synthesis throughout the day, while protein-rich foods also increase satiety and may help control hunger and weight.
A 25-year NIH study linked good hydration—measured by healthy serum sodium levels—to healthier aging, lower risks of conditions including heart failure and dementia, and longer life.
Experts frame the advice as an easy routine change rather than a major overhaul, arguing that consistent hydration and meal-by-meal protein can help people stay stronger and more active over time.
