Protein recommendations get more complicated with age, not less. Here’s what the actual research suggests for men over 50 specifically.
What The Research Shows
Standard protein recommendations were largely developed for younger adults and don’t fully account for anabolic resistance, the reduced efficiency older bodies have at using protein to build muscle. Research on preventing sarcopenia points to roughly 25 to 30 grams of high quality protein per meal as a practical target for stimulating muscle protein synthesis in older adults, rather than one large end of day serving.
Total daily intake matters as much as per meal amounts. Research on protein distribution across meals suggests spreading intake evenly, rather than loading most protein at dinner, better supports muscle related outcomes in older adults specifically.
Quality Matters More With Age
Because of anabolic resistance, protein source and completeness become more important than they were at 30. Complete proteins containing all essential amino acids trigger a stronger synthesis response, and this becomes more relevant as the body’s overall efficiency declines.
The Bigger Picture
For men over 50, the honest answer isn’t a single magic number, it’s consistent, complete protein spread across three to four meals a day, in the range of 25 to 30 grams per meal, rather than treating protein as an afterthought at one meal.

Why don’t standard protein guidelines work as well after 50?
They were largely developed for younger adults and don’t account for anabolic resistance, the reduced efficiency older bodies have using protein to build muscle.
Is it better to spread protein across the day?
Research suggests even distribution across meals, rather than one large dinner serving, better supports muscle-related outcomes in older adults.
Does protein source matter more with age?
Yes, because of anabolic resistance, complete proteins with all essential amino acids trigger a stronger response than incomplete sources.
