Hacker's Diet
Weigh in every day and read the trend line, not the scale — John Walker's The Hacker's Diet, in your browser
John Walker's The Hacker's Diet treats body weight as an engineering problem. The scale is a noisy instrument: salt, water, and last night's dinner move it by pounds from one morning to the next, and that noise hides the change you care about. Walker's fix is a moving average. Weigh yourself daily, log the number, and read the trend line instead of the reading. This tool draws that line for you, so a three-pound jump stays one point and the direction stays visible.

There is no server, no account, and no upload. The log is written to this browser's storage on this computer, and nothing is sent anywhere. Nobody else can read it — including me.
That choice has a cost: the log does not follow you. To move to another computer or another browser, open Import / Export below, export your log to a file, then import that file on the new machine. Export a copy now and then — clearing site data or browser history deletes the log for good.
