Stuart Phillips, PhD, on Building Muscle with Resistance Exercise and Reassessing Protein Intake

Muscle Mass

Stuart Phillips explains that muscle mass is crucial for overall health and longevity. He highlights that maintaining muscle mass is vital for daily activities and reducing mortality risk. Rhonda Patrick adds that muscle mass is a significant component of the frailty index, which predicts mortality in older adults 1.

   

Protein Intake

Stuart Phillips argues that the current Recommended Dietary Allowance (RDA) for protein is too low. He suggests that a minimum intake should be around 1.2 grams per kilogram of body weight, with optimal levels potentially higher for athletes and older adults 2.

   

Aging and Muscle

Aging significantly impacts muscle mass, but physical activity can mitigate these effects. Stuart Phillips notes that inactivity accelerates muscle loss, making regular exercise essential for older adults. He also mentions that disuse events, like illness or hospitalization, can drastically accelerate muscle decline in the elderly 3.
