Why Two Indians Of The Same Age Can Look Worlds Apart Doctor Explains How Muscle Mass May Shape The Way You Age

While genetics often gets the credit for these differences, muscle mass could be one of the key factors shaping how the body ages.

He pointed out that even among people of a similar age, differences in physical appearance and body composition can be significant. “Same age. Similar lifestyle. Very different body composition. But one thing is completely different. This difference is mostly due to muscle mass,” Dr Gupta said.

“Around the age of 30, muscle mass can start decreasing slowly. For this, strength training and protein are very important at this age,” Dr Gupta said. The decline is not simply about losing muscle definition or physical strength. Skeletal muscle plays an important role in supporting movement, maintaining stability and helping the body perform everyday activities.

It can be easy to attribute differences in body shape, strength or ageing to genetics. However, lifestyle factors, including physical activity, nutrition and maintaining muscle mass, can also play an important role. “But we very casually call this genetics,” Dr Gupta said, highlighting how muscle loss can sometimes be overlooked when assessing differences in how people age.

Lower muscle mass can affect more than appearance. Reduced strength may make everyday movements harder and can contribute to poorer balance and mobility as people get older. “Low muscle mass means weak bones, loose balance and fear of falling behind in old age,” Dr Gupta said.

The key takeaway is simple: ageing well isn’t only about eating healthy or staying at the same weight. Maintaining strength and muscle mass can also play an important role in staying active and independent as you age.
