The condition is not simply a byproduct of getting older. Dr. Veller is explicit: sarcopenia is "a medical condition fueled by lifestyle choices." That distinction matters, because it means the trajectory is not fixed. What people eat, how they move, and how they sleep all directly influence how fast muscle deteriorates.
The stakes are concrete. Weaker grip, slower steps, and everyday tasks that drain energy are among the first signs. Left unchecked, sarcopenia reduces independence and raises the risk of falls and injury — making early awareness the most powerful tool available.
What is sarcopenia?
Sarcopenia is the progressive loss of skeletal muscle mass and strength associated with aging. Unlike general muscle fatigue, it is recognized as a distinct medical condition with measurable clinical consequences, including increased risk of falls, fractures, and loss of physical independence. It is distinct from normal aging in that lifestyle factors — diet, exercise, sleep, and hydration — significantly influence its pace and severity.
Sitting, poor sleep, and low protein: the three habits doing the most damage
Of the ten habits Dr. Veller identifies, prolonged sitting ranks among the most damaging. "Prolonged sitting is the new smoking," the article states — it actively signals the body to break down muscle, particularly in the legs and back. Critically, even regular gym sessions cannot fully undo the harm caused by sitting for hours each day. The fix is simple: standing every 30 to 60 minutes and incorporating short walks.

Sleep deprivation compounds the problem. Muscles repair themselves during deep sleep, and getting fewer than 7 hours per night disrupts that recovery process, increases fatigue, and raises injury risk. Dr. Veller recommends prioritizing 7 to 8 hours and reducing screen exposure before bed to protect sleep quality.
Protein intake is the third major factor. As the body ages, its protein requirements actually increase — yet many older adults eat less, often due to digestive issues or persistent myths about meat consumption. Without sufficient protein, muscle tissue wastes away. Including eggs, Greek yogurt, beans, fish, or lean meats in every meal is the recommended correction.
