Weighing daily

In reading other threads, it is hard not to notice the divergence in opinion on the appropriate rate with which to weigh oneself.  Personally, I think it is a matter of personal preference more than anything; some people (myself included) seem to be motivated by a daily trip to the scale and others see it as demotivating and prefer a broader view.  Sounds good.

What I don't understand is why so many people seem determined to try to convince others that weighing daily is a particularly bad choice.  I've seen no less than five posts in the last day or so with some variation on a) weighing daily is less accurate, b) weighing daily is demotivating, or c) weighing daily is frowned upon by the (unspecified) experts.  Now, given that a is absurd, b is just a matter of opinion, and c doesn't match the literature (see, for example, Levitsky 2005; Linde et al 2005; Levitsky et al 2006; Wing et al 2006; Butryn et al 2007; Linde et al 2007; VanWormer et al 2008) I wonder what motivates the "don't weigh daily" recommendation.  Can't we all just get along and weigh ourselves when we please?

Edit: PM me with an email address and I'll send you any of the articles I cited above.

I used to believe it was not advisable to weigh everyday but that's because I was remembering long ago when I was so obsessed I'd get on the scale several times a day and get distressed and give up if I gained weight, even a few ounces, from one day to the next (or one hour to the next).  Now, I primarily chart my weight on Wednesdays but I get on the scale when I feel like it and it's worked out to no more than once per day, in the morning before my first meal. 

All your suggestions that weighing daily  is a good way to determine what foods make one retain water or to catch weight gain due to too much food makes sense to me.  I was a little unyielding when I first joined CC a few weeks ago but "to each his own" sounds like a good policy. 

That some of us believe we are unique but just like everyone else made me laugh because it's so true in my case. 

What works for you is what's right for you as long as your eating is done in a safe and sensible manner.  Thanks, all, you help me every day.
