I guess it depends on your mindset.

I personally had a 7 month lb stall but continued to lose inches so I know that the scale isn't always even 1/2 the story.

That being said I do check the scale every morning to see how I am doing. I now know my water fluctuations, TOM, when I had lots of salt, when I tried a higher glycemic food, and that I jump each night 4-5lbs from the morning.

Ie., for me it is informational how the body works.

Now if my pants were getting tight I might flip out....
