Most of the conversation around protein and muscle focuses on how much to eat. Less attention goes to when, but for men over 50 dealing with anabolic resistance, timing may matter more than it did at 30.
What The Research Shows
Anabolic resistance means the body becomes less efficient at using dietary protein to build muscle as it ages. Research suggests spreading protein intake evenly across meals, rather than loading most of it at dinner, may better support muscle protein synthesis in older adults. A common recommendation from muscle protein research is aiming for roughly 25 to 30 grams of high quality protein per meal, three to four times daily, rather than a small breakfast and one large protein heavy dinner.
The post exercise window also gets attention in research, though its importance may be somewhat overstated in popular fitness media. What matters more consistently is total daily protein intake and distribution, not necessarily eating protein within some narrow window immediately after a workout.
Complete Proteins Matter More With Age
Because of anabolic resistance, protein quality becomes more important, not just quantity. Complete proteins, containing all essential amino acids in adequate amounts, trigger muscle protein synthesis more effectively than incomplete protein sources. Egg whites are one of the most complete and easily digestible protein sources available, which is part of why they show up frequently in research on muscle preservation in older adults.
The Bigger Picture
For men over 50 working on preserving muscle mass, protein timing and distribution across the day appears to matter more than obsessing over post workout windows. Consistent, adequate, high quality protein at each meal is a more evidence backed approach than any single timing trick.

Does the post-workout protein window really matter?
Research suggests its importance may be overstated, total daily protein intake and distribution across meals matters more consistently.
How much protein per meal is ideal after 50?
Research points to roughly 25 to 30 grams of high quality protein per meal, three to four times daily.
Why does protein timing matter more with age?
Anabolic resistance means older bodies are less efficient at using protein to build muscle, making consistent distribution across the day more important.
