I Got My Body Fat Tested Every Way Possible- Shocking Results!

Quick Overview

The body fat measurement comparison revealed significant discrepancies between methods, with DEXA (6.0%) and Underwater Weighing (UWW, 3.2%) being the most precise, while Bioelectrical Impedance Analysis (BIA) and simple Waist-to-Hip Ratio yielded highly inaccurate results (ranging from 20.4% to 32.8% and 10-14% respectively), leading the presenter to conclude that DEXA and UWW are superior for absolute measurement, but skinfolds are best for tracking relative changes.

Key Points: DEXA scan results showed a body fat estimate of 6.0% (222 lbs) after a fat loss phase, compared to 14.0% (216 lbs) a month prior, indicating significant body composition change. Underwater Weighing (UWW), the scientific gold standard, yielded a result of 3.2% body fat, which the presenter notes is likely skewed low due to his dense bone structure. Bioelectrical Impedance (BIA) methods were highly inaccurate: scale BIA estimated 32.8% body fat, and handheld BIA estimated 20.4% body fat. Skinfold measurements varied widely based on the method used: 3-site estimated 4.13%, 9-site estimated 5.9%, and 7-site estimated 8.3%. The presenter judges Waist-to-Hip Ratio as the least valid method for body fat estimation, citing a 0.79 ratio based on 34-inch waist and 43-inch hips. The presenter estimates his true body fat to be around 7-8%, concluding that DEXA and UWW are the most valid of the tested methods, despite their own minor errors (DEXA's 1-3% error rate). The presenter thanks Dr. James Sackett and the Kinesiology team at Cornerstone University for facilitating the testing.

Context: The video features Dr. Mike from RP Strength comparing the accuracy of various body fat testing methods on himself after a significant body recomposition phase spanning from May 13, 2025, to December 12, 2025. The tests performed include Waist-to-Hip Ratio, BIA (scale and handheld), Skinfolds (3, 7, and 9-site), BodPod, DEXA, and Underwater Weighing (UWW) at Cornerstone University in Grand Rapids, Michigan, with the goal of ranking them from least to most valid.
