Macro partitioning
Healthy older adults require approximately 40% more protein per meal (approx. 0.4 g/kg or ~35g) compared to younger adults to maximize muscle protein synthesis due to age-related anabolic resistance.
To build or maintain muscle after age 60, you need more protein per meal than younger people. Aim for about 35 grams of high-quality protein (like 4 oz of chicken or 1 scoop of whey plus eggs) at each main meal, rather than the 20 grams often recommended for athletes. This higher dose is necessary to overcome the natural slowdown in your body's ability to use protein for muscle building as you age.
older people require ~ 40% more dietary protein after exercise to maximize MPS, compared to that required by younger adults [21]. For example, a serving of 35 g (~ 0.4 g/kg/serving) of protein is required to maximize rates of MPS for the average US male over 60 years (88 kg) [24].
