- Muscle Mass: ~33 kg
- Protein Need: ~96 g/day
Insight:
This user can now set a protein-rich diet and structured strength training plan to reduce fat and increase muscle mass effectively.
🥗 Practical Example 2: Fat Loss Journey
A person trying to lose weight inputs:
- Weight: 90 kg

🧬 Why Body Composition Matters More Than Weight
Many people rely only on weight, but two people with the same weight can look completely different depending on muscle and fat ratio.

This calculator helps you understand that quality of weight matters more than quantity.
