How often should I weigh myself?

I believe its personal preference, like others have said if you obsess over gains then its best to weigh weekly, if you know gains are normal then its ok to weigh daily. I weigh every day, I log it weekly on MFP and daily in a spreadsheet along with my food and water and other information and notes.. just so I can keep track of my progress and maybe see things that work and things that don't work.

I like to use my current weight to help track how I eat, but waiting to do a weekly weigh in just seems to be too long. Is weighing myself twice or three times a week doing more harm than good?

The scale is an evil beast. Personally, I don't like the scale for the 'small' weight loss measurements. It just doesn't tell the whole picture. If you lose .4 pounds, did you really lose some weight? Is it a freak weigh in? 10 lbs, ok, there is a genuine amount of weight gone. The really important part is the composition of your body. Use the scale, it is a great tool, but it does not show the whole story. Measure yourself at your neck, shoulders, bust, upper and lower arms, waist, hips, thighs, lower legs and track those measurements. That will give you a much better story of your progess. What mentally sounds better? I lost 1 pound, or I lost a combined total of 4 inches on my body?

I currently weigh my self daily but am planning to log once a week, on a Friday. Although I been registered for 3 weeks I've only been using the site properly for 2 weeks the first week was a test just to see how much i was actually eating everyday and how much of it was rubbish, was a proper eyeopener,
I find weighing myself daily is a benefit in the fact i am encouraged to keep going by the fact the weigh is dropping even by a tiny amount, but on days it doesnt change, or heaven forbid it goes up it actually motivates me to try harder, no scale is going beat me lol.

I am hoping as i get further in this and a visible change is noticable i will be able to reduce the need for weighing myself everyday and just use the way i look as a measure,

I am so glad i found this site, the phone app is the most useful diet tool and i find all the stories inspirational. As someone with only a stone to lose, i think some of the people on here are amazing and when i read about their stories and their amazing weight losses, its like a virtual kick up the backside. I tell myself if they can, i can.

You can weigh yourself anytime you want as long as you're fine with what you see and don't freak out over little fluctuations.

I've actually fashioned wheels onto mine and I use it as my main source of transportation so I can keep an 18-hour long record of fluctuations throughout the day. Then I log it on my arm, then at the end of the day, I close my eyes, make a wish, choose one of the dozens of logged weights, and viola! That's the weight I decide to be that day.

lmao

I weigh daily, but only log it once a week.

Interestingly, I wrote a blogpost about this exact issue today. Feel free to read it : )
