Body Fat Classification (Essential Fat, Athletic, Fitness, Average, or Obese)

Formula Used:

📌 U.S. Navy Method (more accurate, based on body measurements)

For Men:
BF% = 86.01 × log10(Waist – Neck) – 70.041 × log10(Height) + 36.76
For Women:
BF% = 163.205 × log10(Waist + Hip – Neck) – 97.684 × log10(Height) – 78.387

📌 BMI-Based Method (simpler but less accurate)

BF% = (1.20 × BMI) + (0.23 × Age) – (10.8 × Gender) – 5.4
(Gender: Male = 1, Female = 0)
