serious weight fluctuation questions

I weigh multiple times a day. Mornings, after a potty break, before my shower.... I see up to 10lb differences regularly and have found first thing after going in the am is not the lowest average for my weight in a day. I know a lot of people can't even handle once a day on the scale, but weighing multiple times a day has really helped me not worry so much about what the scale says.

Since I started weight training, it's almost seems as if my weight loss stopped going by the scale. I'll stay in the same 10lb range for what seems like forever, often 2 months. Thankfully, I started long enough ago that I've got so much data available now to see that isn't really true. I'll hover in a 10lb range for a couple months, like now at 195lb-205lb. No matter what time of day, what I'm wearing, what I've eaten, I'm going to fall in there somewhere. After a month or so at TOM I'll even go up as much as another 5lb, then about 3-4 days after I'll have a whuoomp down. Then I'll get to do it all over again for a couple months bouncing around 190lb-200lb.

My clothes continue to get looser, my measurements continue to go down and my long-term reports show a downward trend. Personally, I wouldn't worry too much about what the scale says.

If she were weighing in the evening, or throughout the day, the 10 pounds wouldn't be unusual. She's weighing herself in the morning though, right after getting up and before breakfast. Her weight shouldn't be fluctuating that much day to day when she's weighing right away in the morning. There aren't as many variables then, such as if she had a big lunch or dinner since she's had time to digest.

The most I've heard of just plain water weight fluctuations (again, taking into account that she weighs in the morning only, not throughout the day) is a few pounds. I don't have any sort of explanation for it, but it just seems surprising. While it's probably not a concern, it would be an interesting thing to ask a doctor or nutritionist about.

From a guy with over a year's worth of daily weigh ins I would seriously suspect the scales. I started @ 257. The largest single change I have ever seen (first thing, naked) was 6 pounds and that was only one time after a super high sodium day. 2-4 pounds is a normal variance for me. for about $30 check out EatSmart scales on Amazon or at the very least check your scales against a doctors or at a gym. Weight right before leaving the house wearing the same clothes you will weigh in and don't eat, drink or pee on your way there.

Maybe change your batteries ??
