Muscle Loss and Aging
Studies show that around 10 percent of people over 50 are
affected by significant muscle loss—a condition called sarcopenia—and by
the time they reach 80, more than half of all people have to deal with it.
Sarcopenia is actually classified into two types: primary
and secondary. Primary sarcopenia is the normal loss of muscle mass that
happens as we age; it happens whether we want it to or not. As we approach
middle age, we start to lose around 3 percent of our muscle mass per year.
Secondary sarcopenia occurs when there are other
comorbidities present. This kind of sarcopenia isn’t just losing some of
the strength that we had when we were young. It’s the drastic loss of
muscle mass and strength that, when combined with other health issues, can
severely limit our mobility and keep us from performing routine tasks.
It’s this latter type of muscle loss that is more worrisome
because it is more prevalent, more dangerous to our overall health and
well-being, and requires more attention to treat. (Of course, focusing on
building muscle is effective at combatting both types.)
Muscle Loss and Poor Diet
Unsurprisingly, poor diet can have a major effect on your
muscles. In his book Clinical
Nutrition and Aging: Sarcopenia and Muscle Metabolism, Chad
Cox, PhD, talks about the link between diet and muscle loss. He writes,
“Regrettably, poor diet is one of the most common problems
practitioners encounter when treating older adults. Many individuals in
this population have low nutrient intakes, for a variety of reasons….
Dental problems in the elderly may make them more likely to choose softer
foods that often lack protein; delayed gastric emptying can reduce
appetite; hormonal changes may cause longer-lasting feelings of satiety. On
top of that, meat is more expensive than foods rich in starch, [so]
individuals living on a fixed income may tend to fill up on cheap,
processed carbohydrates. Lack of physical strength may also make packaged,
processed foods more appealing.”
All this means that it is all the more important to
continue—or start—to develop good diet habits now to support our major
muscle groups that, with a little help, can quite literally carry us into
old age with health and vigor.
Five Ways to Build Muscle
While losing muscle mass may be a function of aging, that
doesn’t mean we have to lie down and take it. There are many things we can
do to build muscle and keep sarcopenia at bay. Here are five ideas you can
implement today to start your muscle-building journey.
- Incorporate resistance
training into your workout regimen. Resistance exercise in particular has been shown
to be effective at building muscle. Resistance training puts stress on
your muscles; your body responds by telling those muscles to grow
bigger and stronger. There is a wide variety of equipment, such as
resistance bands and dumbbells, that you can cheaply acquire and use
at home, or you can incorporate simple body-weight exercises into your
day to accomplish this as well.
- Go on walks. Walking is absolutely the most underrated form of
movement ever. Walking is a free and simple activity that anyone can
do, and studies have shown that people who walk regularly are less
likely to develop sarcopenia—not to mention have a better overall
quality of life.
- Eat more protein. Protein is the building block of muscle tissue,
which means if you want to gain muscle mass, getting enough protein in
your diet is essential. Eating more lean meat is the obvious way to
increase protein consumption, but there are plenty of other
protein-rich foods too: nuts, seeds, and eggs, just to
name a few.
- Make sure you’re getting
plenty of antioxidants in your diet. Antioxidants help reduce the amount of free
radicals in your body, which reduces inflammation and prevents
oxidative stress, both of which can lower your chances of developing
sarcopenia. Be sure to eat plenty of foods high in antioxidants and
especially carotenoids (like spinach, carrots, and bell peppers) and
flavonoids (blackberries, kale, and citrus fruits, for example).
- Get outside in the sun! Your body needs vitamin D for maintaining bone
density and absorbing calcium. But it also plays an important
metabolic role in muscle health, and increased vitamin D has been
linked to increases in muscle mass. The great news here is the
absolute best way to increase your vitamin D intake is to get outside
and enjoy the sun (using sunscreen, of course). If you live in a
perennially cloudy environment (I’m looking at you, Alaska), you can
boost your levels with a supplement.
Muscle loss affects many millions of older people each year,
but you don’t have to be one of them. By focusing on building muscle via a
good diet, exercise, and lifestyle habits, you can age with confidence and
strength.
