Weighing in 1 day a week vs every day

Every second Sunday I weigh and measure myself!

I weigh myself everyday. But only record once a week on Wednesday.

I weigh about every other morning, but I only log my weight on Thursday mornings. My weight fluctuates a lot from day-to-day (water, time of the month, number of workouts, scale calibration, etc.) so I try not to put too much stock in unofficial weigh-ins. If I find myself focusing too closely on the number on the scale, I only weigh-in on Thursday mornings.

When I was losing, I weighed every day and recorded once a week. I found that weighing daily helped me figure out how certain foods/ times of month would affect my weight. This in turn helped me not to freak out over the fluctuations in my weight, as long as the overall trend was down.

Now that I am in maintenance, I try to just weigh once a week and will hopefully reduce that as I feel I am successfully maintaining.

I weigh in everyday and log it but dont count it as official weigjt until fridays

I weigh in every day and plot it in excel and then plot a trendline. This trendline is what I pay attention to. The daily variations don't bother me.

I do this too. Your weight fluctuates depending on water, salt, and fiber intake, and other factors having nothing to do with calories. Using an exponentially weighted average can help you filter out the noise and focus on the trend, as John Walker explains in "The Hacker's Diet" (http://www.fourmilab.ch/hackdiet/e4/). The chapter on "The Rubber Bag" explains, briefly, the source of these fluctuations. The chapter on "Signal and Noise" explains how some simple math can filter them out. Walker explains how to do the math, but you can also set up a free account on his server to do it for you, or use a service like Beeminder or TrendWeight.com.

Every day, my opinion is that if you're afraid to look at the scale you're not doing something right or you're trying to fool yourself.
make the scale your friend, it's only there to help you and only you control what it tells you.

I weigh several times a day, but the only one that counts is the first one after the weekend. That should be my highest point for the week.

All the others are more to watch how much my weight is stabilized. If i'm fluctuating a lot over the course of the day, I probably need to watch the salt or drink more water. If my weight suddenly shoots up for no good reason, I'm probably gearing up for girly issues and I know to take that into account both for "valid" weight and to steel myself against insane cravings.

I weigh myself daily first thing when I wake up in the morning. I've just learned that I can't get discouraged though with minor fluctuations up and down, because that happens. It's having a long term downward trend that matters the most.

Another advantage of weighing in every day is that it makes it easier to pinpoint what part of your diet is causing you to gain weight, or conversely, what part of your diet is helping you to lose weight. If you suddenly gain 2 pounds in one day you can just go back to the previous day and see what you ate.

If you weigh in once a week, it becomes more difficult to figure things out.
