How often should I weigh myself?

This is a question that is literally asked daily, so you might want to search the archives. It is my sense from prior threads that most people weigh, but don't necessarily record, daily. However, a significant minority find that they over-react to the day to day fluctuations of the scale - their day is ruined if the scale ticks up a pound or two. Those people tend to weigh weekly or even less often. I think few people use this program to record weight daily. If you are going to record daily, do it in Trendweight, or Libra or a similar app that calculatesa trendline, so you can see the big picture and not day to day noise.

It depends.

If you don't have any issues (mentally) with weighing then you could weigh in daily and take an average of those daily weights across the week. Then compare week to week averages to get an idea of which direction your weight is trending.

Averaging those daily values will smooth out the day to day fluctuations that occur naturally.

That being said, if you get a bit stressed out seeing those day to day fluctuations then that's a good reason to weigh in less frequently, in which case you'd want to strike a balance between getting enough data points (weigh in values) and not exposing yourself to that stress too often.

An alternative could be to select 2 or 3 days per week that you weigh in, but keep those steady from week to week and weigh under identical circumstances.

I weigh Sunday morning. Once a week is all I can do-- those day to day fluctuations wreck havoc on my emotions, so I don't go near the scale except on Sunday morning.

I weigh myself everyday. 8 years ago I lost 50 lbs on Weight Watchers and weighed myself daily.
Life and getting cocky thinking I'd never be fat again brought me here.
I like seeing how I'm doing everyday up or down
