Sarcopenia

Sarcopenia is the accelerated loss of muscle mass and strength with aging. It raises the risk of falls, fractures and loss of independence.

Practical use

For whom

Mainly people over 65, those who move little or are recovering from illness or hospital stay.

Not for whom

Not something to wait on: prevention beats recovery, so start early.

In practice

Strength training 2 to 3 times per week plus enough protein (1.2 to 1.6 grams per kilo).

Key caveats

Strength matters more than cardio for muscle; protein without training is not enough.

What we know, and don't

Common misconceptions
"Muscle loss is just part of aging and cannot be stopped."
False. You can slow it considerably with training and protein.Strong evidence
"Cardio alone is enough."
Incomplete. Strength training is essential for muscle.Strong evidence
"It only matters at advanced age."
False. The loss already begins around age 50.Moderate evidence

Heard on podcasts

What popular health podcasts claimed about sarcopenia, checked against the research.

Dr. Gabrielle Lyon · Dr. David ChurchPartly
“People who eat 1.2 grams of protein per kilogram of body weight per day lose more fat mass than those who eat 0.8 grams per kilogram.”

Dr. Mindy Pelz · Dr. Jason FungDoes not hold up
“Fasting does not lead to muscle loss in people with sufficient fat reserves; muscle breakdown is caused primarily by inactivity.”

The Dr. Gundry Podcast · Dr. Steven GundryPartly
“Chronic inflammation leads to muscle loss, osteopenia and osteoporosis.”

Sarcopenia: what's new, and what holds up

We follow the latest research on sarcopenia and listen to leading health podcasts, and we check what they claim. You'll get one email on Thursdays with what matters, and only when there's something new.

You can add more topics later, such as exercise or sleep.
