How to track your weight

To track your weight, weigh at the same time under the same conditions, write the number, and read the trend across weeks rather than any one day. Daily weights swing, so one reading means little.

Same time, same conditions

Weigh first thing in the morning after using the toilet and before eating, on the same scale, in the same clothes. That removes most of the noise, and the number becomes comparable from day to day.

How often

Once a week is enough for many people, and some prefer a few times a week. Daily weighing shows more swings from water and meals, which can be confusing. Choose the rhythm that keeps you calm.

What to write

The date, the number and, if you like, a short note: late night, big dinner, unwell, period. Notes explain the bumps when you read the page later.

Read the trend

Look at the line across four or more weeks, or the average of each week. A single high number is usually water, not fat. Weight rises and falls for many reasons.

Weight is not the whole picture

Sleep, energy, how clothes fit and how you feel matter too. A body measurement tracker adds another view, and the weight tracker printable gives you a place for both.

When to skip it

If tracking weight makes you anxious or affects how you eat, stop and talk to a doctor or a dietitian. This page is general information and not medical advice.
