There's a reason that I qualified the statement. They used a factory-calibrated scales, which uses impedance to measure your body fat percentage. I don't trust the measurements: if you're using impedance to measure it then hydration and the salt balance in your body will dominate any small scale changes in body mass (7kg is < 9% of my body mass). The initial measurements look anomalous, the muscle % and fat % were well out of bounds with my girth/height when compared to the US military-sourced base lines.
