What food a woman over 50 has to eat to maintain and increase muscle mass

Women over 50 can benefit from a diet that includes sufficient protein, carbohydrates, and micronutrients to support muscle maintenance and growth. Here are key recommendations based on insights from the Huberman Lab:

1. Protein and Carbohydrates: Protein, especially leucine, is crucial for muscle synthesis and repair. Consuming 700 to 3000 milligrams of leucine with each meal is beneficial. Carbohydrates also play a role by stimulating insulin, which is anabolic, aiding in the recovery 1. It's advised to obtain amino acids from whole foods, keeping calorie density in mind. For example, animal proteins like meat, chicken, fish, or eggs provide a higher density of essential amino acids than plant-based sources per calorie 1.

2. Micronutrients: Certain micronutrients like vitamin A, zinc, and magnesium are essential for recovery and muscle remodeling. A basic multivitamin can ensure bases are covered 2. Magnesium, in particular, is important, with six milligrams per kilogram of body weight suggested, preferably in the form of magnesium citrate 2.

3. Meal Timing: Early feeding, particularly ingesting proteins early in the day before 10:00 AM, supports muscle maintenance or growth due to enhanced protein synthesis pathways regulated by the BMAL gene 3.

4. Additional Supplements: Other considerations include calcium, vitamin D, and tart cherry juice, which can aid in injury recovery, manage inflammation, and potentially enhance sleep 2.

Remember, it's essential to individualize dietary plans based on health, activity levels, and any medical considerations. Consulting a healthcare professional or a registered dietitian/nutritionist would provide personalized guidance.

Based on insights from the Huberman Lab, here are some meal plan guidelines and key points for maintaining muscle mass, particularly for women over 50.

Meal Plan Guidelines:

1. First Meal (Breakfast)

   • Timing: Ideally before 10:00 AM to maximize protein synthesis due to BMAL gene expression.
   • Protein: 30-50 grams of high-quality protein.
   • Examples: Eggs, Greek yogurt with nuts, protein shake, or lean meats.
   • Carbs: 50 grams from sources like fruits, oats, or whole grains, adding fiber for gut health.
   • Notes: Prioritize protein to set up metabolism for the day.

2. Second Meal (Lunch)

   • Protein: About 30 grams to maintain a positive nitrogen balance throughout the day.
   • Examples: Chicken breast, turkey, legumes, and quinoa.
   • Carbs: Additional 30-50 grams from whole grains, vegetables, or another nutrient-dense source.
   • Note: This meal helps in meeting the daily protein requirements and balancing energy levels.

3. Third Meal (Dinner)

   • Protein: Aim for 30-40 grams.
   • Examples: Fish, beef, tofu, or tempeh to provide complete amino acids.
   • Carbs: 30 grams, consider low-glycemic options such as sweet potatoes or brown rice.
   • Fiber: Include fiber-rich vegetables to aid in digestion and satiety.

4. Optional Fourth Meal (Late Evening)

   • Protein: Casein protein (e.g., cottage cheese, casein shake) to support overnight muscle synthesis.
   • Note: If aiming for muscle hypertrophy, consider incorporating a small meal before bed.

Key Points:

• Protein Turnover: Aging reduces efficiency in protein turnover, hence the focus on adequate protein intake daily. Older adults require higher protein, especially leucine, which is found abundantly in animal proteins 1.
• Insulin Stimulation: Consuming carbohydrates aids in the anabolic process by stimulating insulin 1.
• Mixed Meals: Combining proteins with carbohydrates slows absorption, ensuring sustained nutrient delivery and enhancing muscle protein synthesis than plant protein alone 2.
• Fiber: Include plenty of high-fiber foods to support gut health and manage satiety. Good sources are berries, vegetables, and whole grains 2.

Practical Example:

**Breakfast**: 7:30 AM 
- Scrambled eggs (3 large)
- Whole grain toast (1 slice)
- Fresh berries (1 cup)

**Lunch**: 12:30 PM 
- Grilled chicken breast (150g)
- Mixed green salad with quinoa (1 cup)
- Olive oil and lemon dressing

**Dinner**: 6:30 PM 
- Baked salmon (200g)
- Steamed broccoli (1 cup)
- Sweet potato (1 medium)

**Evening Snack**: 9:30 PM 
- Cottage cheese (1 cup)
- Sliced almonds (20g)

Notes:

• Adjust portion sizes based on individual calorie needs and dietary preferences.
• Consult a healthcare professional or dietitian for personalized advice.

These guidelines and meal examples are derived from discussions and recommendations by Andrew Huberman and Dr. Gabrielle Lyon on the Huberman Lab.

To maintain and build muscle for women over 50, Stacy Sims and Andrew Huberman outline several effective exercises and training principles:

Key Exercises:

1. Heavy Resistance Training

   • Focus on compound movements like squats, deadlifts, chin-ups, and rows. These exercises engage multiple muscle groups and joints, crucial for overall strength.
   • Aim to train with heavier weights rather than high reps to prioritize strength over hypertrophy, which is more beneficial for longevity 1 2.

2. Sprint Interval Training

   • Incorporate high-intensity interval training (HIIT), such as short bursts of sprinting. This is effective for cardiovascular health and helps maintain muscle mass while managing fat 1.

3. Jump Training

   • Engage in jump training or plyometrics to improve bone density and overall muscle strength. This can include exercises like box jumps or vertical jumps. There's evidence that such training can improve bone health significantly, which is particularly important for women over 50 1 3.

4. Unilateral Movements

   • Include exercises that work one side of the body at a time, such as single-leg deadlifts or one-arm rows. These movements can improve balance, coordination, and neural health 2.

5. Supportive Strength Machines

   • Utilize leg presses, leg extensions, leg curls, lat pull-downs, and supported rows if starting with free weights is challenging. These machines can safely facilitate significant strength gains, especially for those new to strength training 4 5.

General Training Principles:

• Intensity and Recovery: Ensure true high-intensity efforts, such as 30-second sprints, and allow ample recovery between sessions.
• Avoid Moderate Intensity: Moderate-intensity workouts, like prolonged spinning or certain fitness classes, may not effectively change body composition and can increase cortisol levels without beneficial hormone responses 6.
• Frequency and Rest: Train the same muscle groups 3-4 times a week or use a split routine if constrained on time. Prioritize adequate rest between heavy training sessions to recover and hit subsequent workouts effectively 2.

Nutrition:

Protein intake is vital for muscle maintenance and growth. Women should aim for 1-1.1 grams of protein per pound of body weight to support muscle recovery and growth 1.

These recommendations from the Huberman Lab emphasize the importance of maintaining muscle and bone health through effective, age-appropriate training strategies and nutrition. Always consult a healthcare professional before beginning any new exercise regimen.
