What is Metabolic Age?

Metabolic age compares your basal metabolic rate (BMR) to the average BMR for your chronological age. If your metabolic age is lower than your actual age, your metabolism is more efficient than average for your age group.

Factors Affecting Metabolic Age

Muscle mass (muscle burns more calories at rest), body fat percentage (fat is less metabolically active), activity level, nutrition quality, sleep, stress, and genetics all influence your metabolic age.

Improving Your Metabolic Age

Build muscle through strength training, reduce body fat through diet and cardio, get adequate sleep (7-9 hours), manage stress, eat protein with each meal, and stay hydrated. Consistency is key.

Quick Tips

  • BMI alone doesn't reflect overall health
  • TDEE varies based on activity level
  • Consult a healthcare professional for medical decisions
