Sarcopenia and Metabolism
Captions available
The idea
Sarcopenia, age-related loss of muscle mass and strength, can begin as early as forty, while body fat tends to rise.
In practice
A large study finding size-adjusted daily energy expenditure stable from about twenty to sixty, declining only after that.
Where people slip
The misconception is that metabolism crashes in the forties; midlife weight gain has causes other than a falling metabolic rate.
