Fat Loss Calculator for Adults Over 40
After 40, your metabolism changes — but not as dramatically as you might think. The real issue isn't a "slow metabolism" but rather decreased muscle mass (sarcopenia), reduced NEAT, and hormonal shifts. Our calculator accounts for these age-related factors to give you realistic, achievable targets.
Key Facts: Fat Loss Calculator for People Over 40
- ✓BMR decreases ~1-2% per decade after 20 (mostly from muscle loss)
- ✓Sarcopenia: 3-8% muscle loss per decade after 30
- ✓Resistance training can reverse years of metabolic decline
- ✓Protein needs increase with age: aim for 1.2-1.6g/kg minimum
Special Considerations for Over 40
- ⚡Prioritize strength training 2-3x/week to preserve muscle
- ⚡Higher protein intake (1.6-2.0g/kg) is even more important after 40
- ⚡Recovery takes longer — don't train the same muscles on consecutive days
- ⚡Get thyroid levels checked if weight loss stalls despite compliance
