When most of us think about muscle, images of strength, fitness, or athletic ability probably come to mind, like Arnold Schwarzenegger or Serena Williams! But did you know muscle is a silent hero when it comes to your overall health, especially with insulin sensitivity and managing diabetes? That’s right, building muscle isn’t just about looking toned and enabling us to lift heavy stuff! It also plays a critical role in how your body processes glucose and keeps your metabolism in check.
How Muscle Affects Insulin Sensitivity and Diabetes
Let’s break it down: insulin is the hormone that helps your body absorb glucose (sugar) from the bloodstream and use it for energy. Insulin sensitivity is how efficiently your cells respond to this process. The better your body is at responding, the better it can maintain healthy blood sugar levels. When you have insulin resistance (or low insulin sensitivity), your cells struggle to absorb glucose, leading to high blood sugar and eventually diabetes.
So, where does muscle come in?
Muscle is your biggest glucose sponge! After you eat, your muscles absorb 70-80% of the glucose from your blood. More muscle mass means more glucose is used up, which keeps your blood sugar levels stable and improves your body’s insulin sensitivity. Plus, muscle is metabolically active—it burns calories even when you’re resting, which helps manage weight and prevent insulin resistance.
The Risks of Losing Muscle
As we get older or become less active, we naturally lose muscle mass, which can lead to insulin resistance and increase the risk of Type 2 diabetes. This is why it’s crucial to stay active and keep building muscle, no matter your age. Think of it like this: the more muscle you have, the better your body is at controlling blood sugar and preventing those blood sugar spikes that can wreak havoc on your health.
And this isn’t just science talk— building muscle has real-life benefits that people like Jan, one of our longtime members, have experienced firsthand. Jan, 89, shared with us how she faced a challenge one day while fishing. She had to navigate a wobbly dock without a railing, tackle box in hand. In the past, she thought, “No way can I do this.” But thanks to the strength and balance she gained in our program, she found herself confidently walking down that dock—something she never thought possible. Increasing her muscle mass not only gave her confidence in her balance— it’s also helping her body better regulate insulin and keep her metabolism humming along, giving her the freedom to move and do the things like fishing. She’s living proof that age doesn’t have to slow you down when you invest in building and maintaining muscle.
How to Build and Keep Muscle
So, how can you keep those muscles strong and help manage insulin sensitivity? Here are some key strategies:
- Strength Training: Lifting weights, using resistance bands, or doing bodyweight exercises (like squats or push-ups) are some of the best ways to build and maintain muscle. It’s all about keeping your muscles active so they can help regulate your blood sugar.
- Protein Intake: Eating enough protein is essential for muscle repair and growth. Whether you prefer lean meats, fish, eggs, or plant-based options like legumes, aim for a balanced protein intake throughout the day.
- Move Regularly: In addition to strength training, staying active with activities like walking, cycling, or swimming can help you burn glucose and improve your insulin sensitivity.
- Healthy Eating: Focus on whole foods like fruits, veggies, whole grains, and healthy fats to keep your blood sugar in check and support your overall metabolic health.
- Be Consistent: The most important thing is consistency. It’s not about doing everything perfectly—it’s about showing up regularly and making small, sustainable changes that lead to big results over time.
Muscle is more than just a tool for strength—it’s one of the most powerful allies you have in managing insulin sensitivity and preventing diabetes. Whether you’re lifting weights, walking regularly, or simply staying active in your daily life, you’re doing more than you know to protect your health and enjoy a more vibrant life.
Jan might have started with the fear of stepping onto that wobbly dock, but she walked away with the confidence that her body can handle life’s physical challenges—and that’s what we want for you too. So, let’s keep moving, building muscle, and making lasting changes that not only improve our strength but support our metabolic health for the long haul!
