Weigh in daily VS. Weigh in weekly

I've read weekly is better. Apparently daily weight fluctuates since the amount of water we tend to hold varies every day and our bodies take time to show real changes in weight. But I step on the scales every day and it can get frustrating when you don't see it moving.

Weighing in weekly is preferable, monthly is even better. Weight fluctuates on a day to day basis, if the scale doesn't affect you in any way then daily is fine but not necessary.

The problem with weighing daily is that you naturally fluctuate. If you're a half pound heavier today than yesterday will keeping to your healthy diet and exercise you DID NOT gain half a pound of fat. You don't need to cut your calories or run even harder today because most likely its just a little extra water hanging around inside your system.
That being said, I usually step on the scale 2 or 3 times a week so I have an idea of what to compare my monday weigh in with, so if I'm unhappy with my official number I know how affected by other factors it may be. But I don't bother if theyre a little up in down, I just use them as data to average out in the end.

I weigh in daily (first thing every morning) and calculate a 7-day moving average to help smooth out daily fluctuations. I'd rather get the feedback sooner than later.

Weighing in daily has worked for me. I am not frustrated with fluctuations because I understand that that's just what the body does. It just keeps me on top of my game. After each weigh in I record my weight on a chart so I can see patterns of weight loss and gain. The record is also a great motivator because I know if I got past a rough spot in the 60s, 50s, and 40s, I know I can get past these last pounds now!

I weigh in every morning in just my boxers. I take 3 day averages to cut out most fluctuations and only report my weight to MFP when I have 3 consecutive days that are similar. I like knowing where I'm at, even though it doesn't drastically change my diet it does make me exercise a lil harder if I go up too much.

Daily. There are plusses and minuses to weighing in daily but I recommend it for the following reasons. If your weight goes up a couple of lbs in one day, you notice it immediately. That is a good thing. Second, it forces you to stay with the program. My wife did Weight Watchers, though she recently stopped. She told me it wasn't working for most of the women in her group, many of whom have been doing it for more than 6 months. The weekly meeting and weigh in fosters a maintenance mentality. Overat for 2 or 3 days, then diet for 3 or 4 days before the weigh in.
