I say that I am going to weigh myself once a week.
My day is Monday, bright and early first thing in the morning.
From what I've read it's important to weigh around the same time everyday. The pull of the moon and gravity or what not.
I have to fight the temptation to weight myself everyday. I want to see the progress too. All this hard work! But I get really down if I see a fluxuation, so it's best if I stick to the once a day.
Also, I haven't noticed a big difference on the scales, but my clothes are fitting a little better. Honestly, I don't care how much I weigh, I'd just like to be smaller.
The real indication for me is extra room in my previously snug jeans!!
