It's water weight loss. Potassium competes with sodium. You take enough potassium and it becomes a diuretic.

- zaptheimpaler 4y agoThis is the right answer!
- quickthrower2 4y agoWhy are they doing studies and not measuring lean mass vs. water vs. fat? Might as well have had shoes on the first weigh in and bare feet on the last one!
- sannee 4y agoThat would probably be way out of budget for them (and would discourage most participants if they had to pay for it themselves). Even here, a bioimpedance body composition thingy is like 10$ and a DEXA scan is around 35$.
- nonameiguess 4y agoThis badly needs to be the top answer, not languishing down at the bottom of the page like it is right now. It never stops amazing me when weight manipulation curious people just ignore the entire history of bodybuilding and weight class sports. A standard American diet, especially if you ever eat out, is very high in sodium, and a high sodium:potassium ratio is one of the chief reasons people retain excess water. Either reducing sodium or increasing potassium is a time-honored way to quickly lose water weight that people in sports have been practicing for decades.
