As an exercise physiologist, I’m often asked about the keys to not only living longer but living better. One key answer lies in an area of health that is often overlooked but incredibly powerful: metabolic health. Drawing inspiration from the work of Dr. Peter Attia, a renowned physician in the field of longevity, I want to share some insights on how optimizing your metabolic health can help you unlock a longer, healthier life.
What is Metabolic Health?
At its core, metabolic health is about how efficiently your body processes energy. This involves everything from how your body handles sugar, to how well it responds to insulin, to how effectively it burns fat. When your metabolic health is in good shape, your risk of chronic diseases like type 2 diabetes, heart disease, and even some cancers is significantly reduced.
Why Insulin Sensitivity Matters
One of the most critical aspects of metabolic health is insulin sensitivity. Insulin is a hormone that helps your body use glucose (sugar) from your food for energy. However, when your body becomes resistant to insulin—a condition often driven by poor diet and lack of exercise—it can lead to elevated blood sugar levels and eventually, chronic diseases.
Improving your insulin sensitivity through regular physical activity, particularly strength training and cardiovascular exercise, is one of the most effective ways to maintain metabolic health. By building muscle mass and enhancing your cardiovascular fitness, you can keep your blood sugar levels stable and reduce your risk of developing metabolic syndrome.
Nutrition: Fueling Your Health
We advocate for smart nutritional strategies to support metabolic health. This doesn’t mean adopting a one-size-fits-all diet, but rather finding what works best for your body. For many, this could involve intermittent fasting, time-restricted eating, or adopting a low-carb or ketogenic diet. There is no single, absolutely, positively, without a doubt best diet for every person to follow, always and forever.
What the science does agree on when it comes to nutrition:
- Total calories: consume an appropriate amount of total energy
- Protein: meeting dietary protein targets to optimize lean body mass and mitigate the risk of sarcopenia (muscle loss).
- Fiber: consuming a diet high in fiber from food sources, usually about 30-35 grams per day for healthy individuals
- Carbohydrate and fat: Intake can vary based on personal preference (eg: high/low fat or high/low carb). However, dietary fat intake should be biased towards unsaturated sources (fish/plant sources), with animal-based saturated fats held to approximately 10% of calories or less. One notable exception is that saturated fats from dairy sources (excluding butter) appear to be healthful as well
These approaches can help regulate blood sugar, reduce inflammation, and promote fat loss—all critical factors for metabolic health.
It’s About Healthspan, Not Just Lifespan
While many people focus on living longer, Dr. Attia emphasizes the importance of “healthspan”—the number of years you live in good health. By prioritizing metabolic health now, you can increase not just the length of your life, but the quality of those years. Imagine being active, independent, and disease-free well into your later years—that’s the true goal.
