Accurate Body Fat Estimator

Fat Detective is an AI-powered tool that provides accurate body fat percentage estimates. By entering your height, weight, and uploading up to three photos, you receive a detailed body composition analysis in seconds.

Our AI-powered body fat estimator analyzes the photos you provide, assessing body shape, proportions, and other visual indicators to deliver a scientifically precise body fat percentage.

Fat Detective's AI technology has been validated against gold-standard DEXA scans, delivering professional-grade accuracy with a margin of error of ±0.5%.

To get results from the Fat Detective, you’ll need to enter your height, weight, and upload one to three full-body photos taken from different angles.

When you complete an analysis with Fat Detective, you'll receive a comprehensive and personalized report that includes:

• Your body fat percentage
• A constructive assessment highlighting strengths and areas for improvement in your physique
• If a body fat goal is specified, a realistic timeline is generated, along with a graph-based projection estimating how long it will take to reach your target from today
• Body composition breakdown, including lean mass and fat mass
• A recommended goal (bulking, cutting, or maintenance) based on your current state
• A daily nutrition plan, with calories and macronutrient breakdown tailored to your objective
• Daily hydration target to optimize performance and recovery
• Sleep recommendations to support fat loss and muscle gain
