How Much Protein After 60: Daily and Per-Meal Targets

https://www.youtube.com/watch?v=lcVdUKo3IcE

The short answer

After 60, protein has a daily target and a per-meal target. Guidance for healthy older adults generally uses 1.0 to 1.2 grams per kilogram daily, with at least 1.2 for those who exercise; a dose study in older men found a per-meal response around 0.4 grams per kilogram. Resistance training belongs beside the food plan, and 30 grams is not a ceiling on usable protein. Chronic kidney disease can change the appropriate target, so a general muscle-building number should not replace a kidney nutrition plan.

What we cover

• The daily target in grams per kilogram for adults over 65, and why expert bodies disagree about the upper end (PROT-AGE 2013)

• What 74 randomized trials found: extra protein showed up as extra lean mass in people 65 and over, and only alongside resistance training (Nunes 2022)

• The per-meal threshold, measured at 0.40 g/kg in men around 71 against 0.24 g/kg in men around 22 (Moore 2015)

• Anabolic resistance in plain language, and the three mechanisms proposed for it (Aragon 2023)

• Why aerobic exercise alone protected muscle least in dieting older adults, 5 percent of lean mass lost against 2 percent with resistance training (Villareal 2017)

• The kidney exception, and the eGFR where it starts (KDIGO 2024, KDOQI 2020)
