Question 1

Is BMI accurate for muscular men?

Accepted Answer

No, BMI often misclassifies muscular men as overweight or obese. If you lift weights regularly, use body fat percentage (should be 10-20% for men) and waist circumference (<40 inches) instead.

Question 2

What's the ideal BMI for men over 40?

Accepted Answer

Men over 40 can healthily carry slightly higher BMI (22-27) as muscle mass naturally decreases. Focus on maintaining muscle through strength training rather than just lowering BMI.

Question 3

Does BMI affect testosterone levels?

Accepted Answer

Yes, significantly. BMI over 30 is associated with 30-50% lower testosterone. Losing weight can increase testosterone levels. Optimal testosterone occurs at BMI 20-25.

Question 4

Why is my waist size more important than BMI?

Accepted Answer

Waist circumference indicates visceral (belly) fat, which surrounds organs and is more dangerous than subcutaneous fat. Men with waist over 40 inches have high health risks even with normal BMI.
