Build Muscle and Burn Fat After 50: How To Do It

Harder To Kill #103

In last week's issue, "The Two Essential Habits Every Man Over 50 Needs to Master to Become Harder to Kill," we covered the foundational practices of resistance training and high-quality protein intake. We emphasized these two high-impact habits as the key strategies for improving health and vitality using the concept of Minimum Effective Dose (MED). This week, we're diving deeper into how to optimize these habits specifically to help you build muscle and burn fat effectively after 50. This complementary guide will provide the exact steps to enhance muscle growth, manage body fat, and achieve a leaner, stronger, and more resilient body.

Can You Gain Muscle and Lose Fat at the Same Time?

Gaining muscle while losing fat is often seen as a challenging goal, especially for men over 50. However, it's not impossible—it just requires diligent commitment to the two key habits: resistance training and high-quality protein intake. By adhering to these habits with consistency and focus, you can achieve both objectives simultaneously, optimizing body composition and improving overall health. Remember, the key is to stay disciplined and make these practices a non-negotiable part of your routine.

Why is Muscle Harder to Gain Than Fat is to Lose?

1. Age-Related Muscle Loss (Sarcopenia):
From the age of 50, most men begin to experience sarcopenia—a natural decline in muscle mass that accelerates over time. Without targeted intervention, muscle mass can decrease by about 1% per year. To combat this, resistance training and adequate protein intake become non-negotiable.

2. Decline in Hormone Levels:
Key hormones like testosterone and growth hormone, which are essential for muscle growth, decline with age. Optimizing these hormones can make a significant difference in muscle-building efforts. We recommend getting comprehensive blood work done and consulting with a physician trained in longevity or functional medicine. Consider tests for free and total testosterone, estradiol, IGF-1, and thyroid function to get a full picture of your hormonal health. Exploring options like bio-identical hormone replacement therapy (BHRT) could help if hormone levels are low, supporting muscle gain and overall vitality.

3. Reduced Anabolic Response:
Older adults have a diminished muscle-building response to stimuli like protein intake and resistance exercise, known as anabolic resistance. To overcome this, higher protein intake and consistent strength training are critical.

Understanding Protein Utilization and Synthesis After 50

As you age, your body’s ability to utilize protein for muscle building changes significantly:

1. Decreased Muscle Protein Synthesis (MPS):
MPS—the process of repairing and building muscle fibers—becomes less efficient after 50. To counteract this decline, older adults need a higher protein intake per meal, focusing on high-quality proteins that contain leucine, a key amino acid that triggers muscle growth.

2. Increased Protein Requirements:
To overcome anabolic resistance, men over 50 need more protein. Experts like Dr. Gabrielle Lyon and Dr. Mark Hyman recommend consuming 1 gram of protein per pound of ideal body weight daily to support muscle growth and maintain muscle mass.

How Does Protein Intake Affect Fat Loss and Muscle Gain?

1. Impact on Gaining Muscle:

  • Higher Protein Needs: Aiming for 1 gram of protein per pound of ideal body weight ensures sufficient intake to stimulate muscle growth. Distribute this protein evenly across meals to maximize muscle protein synthesis.

  • Minimum Protein Per Meal: To effectively stimulate muscle protein synthesis, each meal should contain at least 25-30 grams of high-quality protein. This threshold, which equates to approximately 2.5-3 grams of leucine, is crucial for overcoming anabolic resistance and ensuring muscle growth.

  • Resistance Training is Crucial: Regular resistance training, particularly with compound movements (like squats, deadlifts, bench presses, and rows), is essential to counter anabolic resistance and promote muscle growth. Newcomers to strength training may experience "beginner's gains," where muscle growth is rapid due to new stimuli, while experienced lifters may need more advanced techniques to continue making progress.

2. Impact on Burning Fat:

  • Muscle Mass and Metabolism: More muscle mass leads to a higher resting metabolic rate (RMR), which helps you burn more calories at rest. Maintaining muscle through adequate protein and resistance training is key for fat loss.

  • Thermogenic Effect of Protein: Protein requires more energy for digestion than fats or carbohydrates, slightly increasing daily calorie expenditure and helping maintain a caloric deficit for fat loss.

  • Focus on High-Quality Whole Foods: Prioritize whole foods over processed ones. Men who consume the same macronutrients (protein, fat, and carbs) but derive them from high-quality whole foods (like lean meats, fish, vegetables, and whole grains) often achieve better health outcomes than those relying on processed foods. Whole foods provide essential nutrients, vitamins, and minerals that support muscle growth, recovery, and overall health.

Why the Goal Shouldn’t Be Just to Lose Weight

Many men believe that losing weight is the ultimate goal for improving health and fitness. As a result, they often resort to extreme calorie restriction and chronic cardio sessions. While this approach might help drop pounds on the scale, it can have unintended consequences—especially for men over 50.

When you focus solely on losing weight, you risk losing not just fat but also muscle mass. This muscle loss can have several negative impacts:

  • Decreased Strength: Muscle is essential for maintaining strength, stability, and functional capacity. Losing muscle makes you weaker, less capable, and more prone to injuries.

  • Slower Metabolism: Muscle is metabolically active tissue, meaning it burns more calories at rest than fat. Losing muscle slows your metabolism, making it harder to maintain weight loss over time and easier to regain fat.

  • Diminished Healthspan: A loss of muscle mass is associated with increased frailty, reduced mobility, and a greater risk of age-related diseases. Maintaining or building muscle is critical to staying strong and independent as you age.

Instead of focusing on weight loss alone, the goal should be to lose fat while preserving or gaining muscle. This approach enhances your body composition, boosts your metabolism, and supports long-term health. Achieving this requires a combination of resistance training, adequate protein intake, and a moderate caloric deficit—not chronic cardio or extreme calorie restriction.

By shifting your focus from simply losing weight to building a leaner, stronger, and more resilient body, you set yourself up for sustainable success and a healthier, more vibrant future.

Actionable Steps to Build Muscle and Lose Fat Safely

To help you leverage these principles, here’s a step-by-step guide tailored for men over 50:

1. Get an InBody Scan:
Begin with an InBody Scan or a similar body composition analysis. This provides key metrics like:

  • Body Fat Percentage: The percentage of your weight that is fat.

  • Total Fat Mass: The total weight of fat in your body.

  • Visceral Fat Level: The amount of fat around your internal organs (an important indicator of metabolic health).

  • Skeletal Muscle Mass: The total weight of muscle in your body.

These measurements will serve as your baseline for tracking progress. To find a location near you, visit this link.

2. Determine Your Ideal Body Weight:
Calculate your ideal body weight at 15% body fat—a healthy target for optimal health and performance.

  • Step-by-Step Calculation:

    • Lean Body Mass (LBM):

      • LBM = Current Weight x (1 - Current Body Fat Percentage)

    • Ideal Body Weight (IBW) at 15% Body Fat:

      • IBW = LBM / (1 - 0.15)

Example Calculation:
If you weigh 200 lbs with a current body fat percentage of 25%:

  • Current LBM = 200 lbs x (1 - 0.25) = 150 lbs

  • Ideal Body Weight at 15% body fat = 150 lbs / (1 - 0.15) ≈ 176 lbs

This means your target weight should be around 176 lbs to achieve 15% body fat, assuming no loss in muscle mass.

Note: For a more personalized calculation, use this link to access our Google Sheets model, where you can input your current body weight and body fat percentage to easily calculate your ideal body weight at a given body fat percentage. You’ll need an InBody scan (see link above).

3. Set Your Protein Intake Goals:
Based on your ideal body weight, aim for 1 gram of protein per pound of ideal body weight to counter anabolic resistance and promote muscle protein synthesis.

  • Calculate Your Protein Needs:
    For a man with an ideal body weight of 176 lbs:

    • Daily protein intake = 1 gram per pound of ideal body weight

    • Required protein intake = 176 grams of protein per day.

To gradually reach this protein target, start by consuming 70% of the calculated amount and then increase your intake by 10 grams per week until you reach the full target.

  • Initial Protein Intake Calculation:

    • 70% of 176 grams = 123 grams of protein per day.

  • Weekly Increases to Reach Target:

    • Week 1: 123 grams of protein per day

    • Week 2: 133 grams of protein per day

    • Week 3: 143 grams of protein per day

    • Week 4: 153 grams of protein per day

    • Week 5: 163 grams of protein per day

    • Week 6: 173 grams of protein per day

    • Week 7: 176 grams of protein per day

By increasing your protein intake by 10 grams per week, you allow your body to adjust gradually, improving digestion and absorption, and making it easier to reach your target protein goals comfortably.

4. Goal: Gain 1 lb of Lean Muscle Per Month:
While gaining 1 pound of muscle per month is a realistic goal for many men, particularly beginners, individual results can vary based on training experience, genetics, diet, sleep, and consistency. For those new to strength training, muscle growth may happen more rapidly at first, but as you become more experienced, achieving this rate of growth may require more strategic efforts. For men over 50, factors such as anabolic resistance and slower recovery may also impact the rate of muscle gain. Adjust your expectations based on your unique circumstances, but remain consistent and committed to your plan.

To achieve this goal, focus on:

  • Resistance Training: Train 3-4 times per week, focusing on all major muscle groups with compound movements to maximize muscle recruitment and build functional strength.

  • Progressive Overload: Gradually increase weight, reps, or sets to ensure continuous muscle adaptation and growth.

  • Protein Timing and Distribution: Ensure each meal contains at least 25-30 grams of high-quality protein to maximize muscle protein synthesis. Consider consuming a protein-rich snack or shake post-workout to optimize recovery.

Can You Lose Fat and Gain Muscle at the Same Time?

Many believe that losing fat and gaining muscle simultaneously is impossible, but we've seen otherwise. For men who commit to regular resistance training and follow a high-protein diet, monthly InBody scans often show both a drop in body fat and an increase in muscle mass.

Here's what typically happens: As you work towards your target body fat percentage, you may notice muscle gains, even in a caloric deficit. This is especially true if you’re new to strength training or have a higher body fat percentage. Once you reach your ideal body fat level and increase your calorie intake while continuing strength training with progressive overload, adding muscle becomes easier. The increased calories provide the fuel your body needs to build new muscle tissue while maintaining the progress you've made.

The key is consistency: Stick with your nutrition plan, track your progress, and stay committed to your workouts. You might just surprise yourself with the results!

5. Safe Fat Loss Target:
Aim for a 1-2 lb fat loss per week, translating to about 4-8 lbs of fat loss per month.

  • Caloric Deficit: Create a moderate caloric deficit of 300-500 calories per day by reducing empty-calorie foods and increasing nutrient-dense options.

  • Increase Activity Levels: Include daily low-intensity activities (walking, cycling, swimming) for at least 30 minutes most days of the week.

  • Prioritize Protein and Fiber: Focus on high-protein, fiber-rich foods to maintain satiety and support fat loss.

6. Monitor Progress and Adjust:

  • Regularly Track Metrics: Use the InBody Scan every 4-6 weeks to monitor body fat percentage, muscle mass, and visceral fat changes.

  • Adjust Protein Intake and Workouts: Modify your diet or exercise intensity if progress stalls.

Additional Tips for Success

  • Recovery and Mobility: Include active recovery and mobility exercises to prevent injury, improve range of motion, and ensure long-term adherence.

  • Sleep and Stress Management: Aim for 7-9 hours of quality sleep per night and practice stress management techniques like meditation or deep breathing. Quality sleep is crucial for muscle recovery, hormonal balance, and optimal performance.

  • Hormonal Optimization: Consider comprehensive blood work to assess hormone levels and consult a physician trained in longevity or functional medicine to explore options like bio-identical hormone replacement therapy (BHRT) if necessary.

  • Consider Supplements: If meeting protein needs through food alone is challenging, consider supplements like whey protein (20-30 grams post-workout), omega-3 fatty acids (1-2 grams EPA/DHA daily), or creatine (3-5 grams daily) to enhance muscle growth and recovery.

  • Community and Accountability: Engage with a community or find a workout partner for support and motivation. This helps maintain commitment and consistency.
