Fact check: Palantir CEO Alex Karp's body composition report shows 8% body fat, 67.5 kg of muscle mass, and a metabolic age of 43.

Verdict: mostly true — Trust Score 79/100

This post reported by Benzinga, Axios, and recent interview transcripts. While the 'Body Composition Analyzer' scan itself remains an unverified leak, the metrics it contains (8% body fat, 67.5 kg muscle mass) are consistent with Karp's long-documented fitness level, and the 5:30 dead hang claim was indeed made by Karp in a June 2026 interview.
