Ever notice how some people seem to have boundless energy well into their later years while others start feeling sluggish before they hit 40? That isn’t necessarily genetics—it could very well be their metabolic health. The metabolism isn’t just about burning calories. It’s the foundation of how your body creates energy, processes nutrients, and maintains balance. When it’s running smoothly, you probably feel strong, clear-headed, and resilient. But when it’s out of sync, fatigue, weight gain, and chronic issues creep in.
The good news? You don’t have to accept a sluggish metabolism as part of aging. With the right holistic strategies, you can keep your metabolism strong and adaptable, no matter your age.
What is Metabolic Health?
Metabolic health is your body’s ability to process and use energy. It affects everything—your weight, energy levels, mood, and even your risk for chronic diseases.
Key markers of metabolic health include:
- Stable blood sugar levels: Prevents energy crashes and long-term damage to the body
- Balanced cholesterol and lipid levels: Supports heart and brain function
- Efficient insulin response: Reduces inflammation and supports steady energy
- Healthy gut function: Impacts digestion, nutrient absorption, and hormone balance
Metabolism naturally shifts with age, but it doesn’t have to decline. The right lifestyle choices can keep it working in your favor, helping you stay energized, strong, and mentally sharp.
How Metabolism Changes with Age
Metabolism isn’t static—it evolves with every stage of life. While some changes are inevitable, how you support your body determines whether these shifts work for or against you. Below is what happens to metabolism as you age and how to keep it working in your favor:
In Your 20s and 30s
At this stage, metabolism is generally at its peak. Your body burns calories, builds muscle, and recovers quickly. However, lifestyle habits play a huge role in whether your metabolism stays strong or starts to slow down prematurely.
What Can Help:
- Strength training and regular movement to maintain muscle mass
- Eating enough protein and whole foods to support metabolism and hormone balance
- Managing stress and sleep
What Can Harm:
- High stress, poor sleep, and excessive processed foods can lead to insulin resistance
- Sedentary lifestyles set the stage for a slower metabolism later on
In Your 40s and 50s
This is when many people start noticing weight gain, lower energy, and hormonal changes. Muscle mass naturally declines, and insulin sensitivity can decrease, making it easier to store fat and harder to maintain energy levels.
What Can Help:
- Strength training becomes even more essential to counteract muscle loss
- Prioritizing protein, fiber, and healthy fats to balance blood sugar
- Supporting hormones naturally with stress management, adaptogens, and gut health
What Can Harm:
- Chronic stress leads to higher cortisol levels, which can promote fat storage
- Crash diets or excessive calorie restriction can slow metabolism further
- Neglecting muscle-building exercises accelerates metabolic decline
In Your 60s and Beyond
As metabolism slows, the focus shifts to preserving strength, mobility, and cognitive function. Nutrient absorption declines, making it even more important to focus on whole foods and digestion. Inflammation can increase, impacting everything from energy levels to joint health.
What Can Help:
- Resistance training and functional movement to maintain independence
- Anti-inflammatory foods rich in antioxidants and important nutrients
- Prioritizing gut health for better digestion and nutrient absorption
- Managing stress, social connections, and purpose-driven activities to support your overall wellness
What Can Harm:
- Ignoring muscle loss, leading to frailty and reduced metabolism
- Nutrient deficiencies, especially protein, vitamin D, and B vitamins
- Lack of movement and a sedentary lifestyle
How To Keep Your Metabolism Strong at Every Age
Metabolic health isn’t just about your genetics—it’s about how you support your body daily. The right habits can keep your metabolism running efficiently, helping you feel energized, maintain a healthy weight, and reduce the risk of chronic conditions.
Below are tips for how to potentially keep your metabolism working for you at every stage of life. However, keep in mind that it’s always best to consult with a medical provider before making changes to your diet or exercise program.
Build and Maintain Muscle Mass
Muscle is metabolically active, which means it burns calories even at rest. As you age, muscle loss naturally occurs, slowing your metabolism—but strength training helps prevent this. Maintaining muscle is also important for bone health, reducing the risk of fractures as you get older.
- Consider focusing on resistance training at least 2 to 3 times a week, using weights, bodyweight exercises, or resistance bands
- Prioritize protein intake to support muscle repair and growth
- Stay consistent—muscle maintenance is an ongoing process, not a one-time fix
Balance Blood Sugar Levels
Frequent spikes and crashes in blood sugar can lead to insulin resistance, high blood pressure, inflammation, and a sluggish metabolism. Keeping blood sugar stable helps maintain steady energy and supports long-term metabolic health.
- Eat protein, fiber, and healthy fats at every meal to slow down sugar absorption
- Avoid excessive refined carbs and sugar, which cause blood sugar fluctuations
- Stay active after meals—even a 10-minute walk can help regulate blood sugar
Prioritize Quality Sleep
Poor sleep disrupts hormones that regulate appetite, metabolism, and stress. Chronic sleep deprivation increases cravings for processed foods and contributes to metabolic dysfunction. It can also negatively impact mental health, making it harder to manage stress and energy levels.
- Try to get seven to nine hours of restful sleep per night
- Maintain a consistent sleep schedule to support circadian rhythm and metabolic balance
- Avoid late-night eating and limit blue light exposure (from phones and tablets) before bed
Support Gut Health
Your gut microbiome plays a key role in digestion, inflammation, and metabolic function. A healthy gut helps process nutrients and supports weight management.
- Eat fermented foods (kimchi, yogurt, sauerkraut) to introduce beneficial bacteria
- Increase fiber intake with vegetables, legumes, and whole grains to feed good gut bacteria
- Stay hydrated and avoid excessive antibiotics that can disrupt your gut balance
Manage Stress to Protect Your Metabolism
Chronic stress elevates cortisol levels, which can lead to increased body fat storage, muscle breakdown, and insulin resistance. Learning how to regulate stress is important for metabolic balance.
- Practice deep breathing, yoga, or meditation to lower cortisol levels
- Set healthy boundaries around work and personal life to reduce chronic stress
- Get outside and move daily—nature and movement help regulate stress hormones
Stay Active Throughout the Day
Beyond structured workouts, daily movement and physical activity play a big role in metabolic health. Long periods of sitting can slow down metabolism, while regular movement keeps your body in an energy-burning state. For healthy older adults, consistent movement also helps maintain mobility and balance.
- Take movement breaks every hour if possible—stand up, stretch, or take a short walk
- Incorporate walking, biking, or standing desks into your routine
- Try to get at least 5,000 steps per day (depending on ability and current health)
Support Hormonal Balance Naturally
Hormones like insulin, thyroid hormones, and cortisol impact metabolism. When they’re out of balance, energy levels and weight management become more difficult.
- Eat a healthy diet rich in whole, nutrient-dense foods to provide important vitamins and minerals
- Reduce endocrine disruptors (plastics, processed foods, toxins) that affect hormone function
- Work with a holistic practitioner to test and optimize hormone levels naturally
Optimize Mitochondrial Health for Energy Production
Your mitochondria are the powerhouse of your cells, responsible for converting food into energy. Supporting mitochondrial function keeps metabolism efficient and reduces fatigue.
- Focus on antioxidant-rich foods (berries, greens, turmeric) to reduce oxidative stress
- Get adequate omega-3s from fatty fish, walnuts, and flaxseeds for cellular function
- Consider targeted supplements like CoQ10, magnesium, and B vitamins to fuel mitochondria
Choose Nutrient-Dense Foods for Metabolic Health
A balanced diet of healthy eating helps regulate metabolism and provides the nutrients your body needs to function optimally. Prioritizing healthy meals made from whole foods reduces inflammation and supports long-term well-being.
- Swap processed foods for whole, nutrient-dense options
- Choose fat-free milk as a protein-rich alternative to sugary beverages
- Limit saturated fat intake
By incorporating some of these habits into your routine, you can support healthy aging, sustain energy levels, and maintain a strong metabolism at every stage of life.
Again, it’s always best to consult with a medical provider before making any changes to your diet or exercise routine.
