Choosing the Right Tool

• Goal clarity: Precise recomposition benefits from DXA + measurements. Lifestyle goals thrive with BIA trends.

• Consistency: Measure at the same time, hydration, and temperature to reduce noise.

• Complementary data: Pair composition with photos, strength logs, and subjective energy scores.

Beyond BMI

Use waist-to-height ratio, WHR, and fat-free mass index to spot cardiometabolic risk earlier than BMI alone.
