What the scale hides

Water, salt, sleep and cycles: the daily noise on the scale and how to read past it. A 2-minute lesson from the neo academy.

Day-to-day scale changes are mostly water. A salty dinner, a hard workout, poor sleep, travel, or a menstrual cycle can swing the number by several pounds overnight, in either direction.

That's why this app tracks your trend line, not single weigh-ins. The trend smooths the noise and shows the real direction underneath.

A single 'up' morning after a good week is almost never fat gain. Fat change is slow; water change is fast. If the trend is still heading down, nothing is wrong.

Progress photos, how clothes fit, energy levels, and strength are all measurements too. On a flat scale week, check those. They often keep moving.

Judge the trend, not the day. Water noise isn't weight gain.
