GPT-4's Body Fat Estimation: A DEXA Scan Competitor?
2025-05-16
A surprising study reveals that GPT-4o can estimate body fat percentage from photos with accuracy rivaling gold-standard DEXA scans. Using images from Menno Henselmans' "Visual Guides to Body Fat Percentage," the model achieved a median absolute error of 2.4% for men and 5.7% for women. While not a medical diagnosis, this offers a more affordable alternative to DEXA scans, particularly given the limitations of outdated BMI measurements. This could be a game-changer for accessible health assessments.
