Older ICU patients (>60 years) require higher protein intakes (approaching 2.0–2.5 g/kg/day) to achieve positive nitrogen balance and stimulate muscle protein synthesis, due to age-related anabolic resistance.
If you are over 60 and in the ICU, your body needs significantly more protein than the standard recommendation to stop muscle loss. Aim for 2.0 to 2.5 grams of protein per kilogram of your usual body weight daily, prioritizing high-quality proteins rich in leucine. This is safe unless you have severe kidney failure. Combine this nutrition with early physical therapy or movement to maximize muscle retention.
The encouraging conclusion, however, is that older patients in the ICU were able to achieve nitrogen equilibrium but only with protein intakes that approached 2–2.5 g/kg/d.
Why this rating
Based on observational nitrogen balance studies and expert consensus/reviews rather than large-scale RCTs specifically for this high-dose protocol in older ICU patients.
