The short answer

At least once a week, at the same time and under the same conditions, ideally first thing in the morning. Many people do even better weighing in daily or several times a week and watching the trend rather than any single number. Regular weigh-ins are one of the most common habits among people who keep weight off for years.

Why the scale matters so much in maintenance

The scale is your early warning system. It catches a two- or three-pound gain while it's still easy to reverse. Without it, regain stays invisible until your clothes start to feel tight, and by then it's often ten pounds or more.

How to weigh in

If the scale stresses you out

Weekly is plenty. The goal isn't to judge yourself by a number. It's to get honest information early, so you never have to face a big regain. Treat the scale like a smoke detector: you're glad it's there, and you're glad when it stays quiet.

Know your lines

Decide in advance what the number means: at 5 pounds over your goal, tighten up. At 10, go back to a short, structured reset. Read The Trigger Weight to set yours.
