I bought the EatSmart Precision Digital Bathroom Scale from amazon recently. Love it! My old digital scale would fluctuate up to two pounds depending on where in the kitchen I had it. I found the spot that always registered the lowest weight.. Hehe. But this new scale is always the same weight no matter where I have it so I highly recommend it for accuracy.
I'd love to know the same thing, because my sister and my Dad both have the same scale and I hopped on my sisters about a 1 and half ago and it said "139" then hopped on my Dad's about 5 days later and it said "141" I know it IS technically possible that I could have gained that weight by water or something, but I'd been dieting and keeping my calories under 1,200 every single day. I'm thinking the scales are not very accurate..
I am lightest in the morning, so I try to weigh myself then too, lol. Whenever I go to the Dr or midwife or something though it is always in the afternoon, after I have eaten etc, so I am always 3-5lbs heavier... I hate that, lol.
i used to have one that you could step on 3 x's in a row...and it would read different each time - I was getting scale OCD! I replaced it and this new one gives the same reading if I did it 10 x's in a row or 2 or just 1...so I got rid of my scale OCD! Anyway, I will check tomorrow to see what brand it is and try to remember to post back! It was around 30-35.00 at walmart and worth it for its accuracy. I never realized how annoying the other scale was until I got a decent one. :0)
