Muscle Stabilizes Blood Sugar
While muscle is important for strength, it’s actually involved in a lot more than that in the body. Few people realize that muscle also helps maintain normal blood sugar levels.
In fact, some experts believe the downward spiral to diabetes begins when insulin is no longer effective at helping muscle clear glucose from the blood.
It stands to reason then, that as muscle mass diminishes, it impairs the ability to keep blood sugar stable. That increases the likelihood of developing insulin resistance and type 2 diabetes.
The opposite is also true. As you build muscle, improvements in insulin resistance follow. Researchers at the Human Nutrition Research Center on Aging at Tufts University studied 62 middle-aged and older adults with type 2 diabetes during 16 weeks of strength training and found that when muscle increased, insulin resistance improved significantly.
