Physical Activity (PA): The Modifiable Factor in Your Metabolism



Personal training in Birmingham

Nutrition First, but Exercise Matters Too


Let’s be honest: when it comes to weight loss, nutrition is king. The calories you consume and the quality of your food will always be the most critical factors. But that doesn’t mean we can ignore physical activity. PA isn’t just about burning calories—it’s about building a stronger, healthier body from the inside out. From improving metabolic markers like blood sugar levels to reducing visceral fat and enhancing your longevity, PA is a powerful tool for transforming your health.


Here’s how the different types of PA can help—and why it’s worth focusing on more than just the scale.


The Benefits of Physical Activity Beyond Weight Loss


1️⃣ Resistance Training: Build Strength and Longevity

  • Builds lean muscle, which increases Resting Metabolic Rate (RMR)—helping you burn more calories at rest.

  • Improves metabolic health by regulating blood sugar and enhancing insulin sensitivity.

  • Grip strength, often linked to resistance training, is a strong predictor of a longer lifespan.

  • Metabolic Birmingham Insight: "Resistance training isn’t just for muscle—it’s for long-term health."


2️⃣ Cardio: Burn Fat and Boost Heart Health

  • Reduces visceral fat, the harmful fat around your organs linked to chronic diseases.

  • Improves VO2Max, which is the best predictor of longevity and overall health.

  • Supports cardiovascular health, reducing the risk of heart disease and stroke.

  • Metabolic Birmingham Insight: "VO2Max isn’t just about performance—it’s about living longer and stronger."


3️⃣ High-Intensity Interval Training (HIIT): The Metabolic Booster

  • Combines strength and cardio benefits in shorter, efficient workouts.

  • Increases post-exercise calorie burn through the afterburn effect (EPOC).

  • Enhances cardiovascular fitness and metabolic flexibility, allowing your body to switch between burning carbs and fats more effectively.


PA Complements Nutrition for Fat Loss

While physical activity isn’t the biggest driver of fat loss, it plays a crucial supporting role:

  • Resistance training preserves muscle mass during weight loss, preventing a drop in metabolism.

  • Cardio and daily movement (NEAT) increase your calorie burn, creating a larger deficit.

  • Together with nutrition, PA helps you lose fat while maintaining strength and energy.


How to Optimise PA for Your Health and Goals

1️⃣ Combine Resistance and Aerobic Training

  • Resistance training improves strength, metabolic markers, and bone health.

  • Cardio burns fat, reduces visceral fat, and enhances heart health.

  • Example Weekly Plan:

    • 2-3 strength sessions per week.

    • 2-3 cardio sessions, like walking, jogging, or cycling.

2️⃣ Focus on Longevity Metrics

  • Train to improve VO2Max for better cardiovascular health.

  • Build grip strength through resistance exercises—this is a key marker of long-term vitality.

3️⃣ Don’t Overlook Daily Movement

  • Small, consistent actions like walking, standing, and stretching (NEAT) boost your metabolism and energy levels.

4️⃣ Make PA Sustainable

  • Choose activities you enjoy—whether that’s weightlifting, hiking, or dancing.

  • Focus on consistency over intensity for long-term results.


Key Takeaways

  • Nutrition is King: PA won’t outdo a poor diet, but it complements a solid nutrition plan beautifully.

  • Beyond the Scale: Resistance training and cardio improve metabolic health, reduce disease risk, and increase lifespan.

  • Consistency Wins: Sustainable, enjoyable movement leads to better health and fitness over time.
