You
are slim, your weight is normal, you eat reasonably well and nobody in your
immediate family has diabetes. So, when a blood test shows
elevated blood sugar, it comes as a surprise. You may wonder what you did
wrong. Was it the rice? Should you have avoided the occasional sweet? But there
is another possibility that rarely enters the conversation: you may have too
little muscle.
Muscles
do much more than help you lift weights, climb stairs or carry groceries. They
play a crucial role in regulating blood glucose. And if you have less muscle
than your body needs, you may be at greater risk of developing type 2 diabetes,
even if you don’t look overweight.
Why
muscle matters for blood sugar
The
muscles in your legs, arms and back act as a reservoir for glucose. Insulin, a
hormone produced by the pancreas, signals muscle cells to absorb glucose from
the bloodstream. Muscles use this glucose for energy or store it for later.
With less muscle, there is less tissue available to take up glucose. How
effectively your muscles respond to insulin matters, too.
When
muscle cells become resistant to insulin, the pancreas has to release more of
the hormone to do the same job. For a while, this extra insulin may keep blood
glucose under control. But over time, the pancreas may struggle to compensate,
allowing blood sugar levels to rise.
Why
slim Indians may be at risk
You
can have a normal body mass index (BMI), look slim and still carry more body
fat and have less muscle than another person of the same height and weight.
Researchers describe this as the “thin fat” phenotype, which is relatively
common among Indians.
The
problem is not always visible. Fat can accumulate deep in the abdomen and around
organs such as the liver, making the body less responsive to insulin.
Combined
with lower muscle mass, this can increase the risk of type 2 diabetes and heart
disease.
This
helps explain why South Asians tend to develop type 2 diabetes at younger ages
and at lower BMIs than people of white European ancestry. Family history is one
risk factor, but its absence does not guarantee protection.
When
everyday tasks become harder
Research
following people over time has linked lower muscle strength with a greater
likelihood of developing type 2 diabetes. The relationship can also work in the
other direction: people with diabetes may lose muscle faster.
When
both muscle mass and strength are low, doctors call the condition sarcopenia.
It becomes more common with age. You may notice it in small ways. Perhaps you
once carried a full bucket of water to the balcony but now prefer filling it
halfway because it feels too heavy. Such changes in everyday strength can be
easy to overlook.
Build
muscle, not just step count
Walking
after meals helps muscles use glucose and is beneficial for blood sugar
control. But walking alone may not be enough to maintain muscle strength.
Try
simple resistance exercises at home. Stand up from a sturdy chair and sit down
slowly, do wall push-ups or use a resistance band. Start at a level you can
manage and gradually increase the difficulty. Aim for strength-building
exercises at least twice a week. Regular walking should remain part of your
routine.
Give
protein a place at the table
Muscles
need protein to repair and rebuild. If breakfast is usually poha, consider
adding an egg or a bowl of curd. At lunch, include protein sources such as dal,
chana, rajma, paneer, tofu, fish or chicken, depending on your dietary
preferences.
Pay
attention to how much protein you actually eat. A couple of spoonfuls of dal
over a large serving of rice may not provide as much as you think.
Losing
weight? Protect your muscle
Losing
excess body fat can improve blood glucose, but weight loss can also reduce muscle
mass. Include resistance exercises and adequate protein in your weight-loss
plan to help preserve muscle.
Your weight may remain unchanged
even as muscle decreases and fat increases. So don’t judge your metabolic
health by the weighing scale alone. Maintaining muscle strength is important
even if you have never been overweight.
