Do you weigh every day...and if you do

I weigh daily and enter my weight into Happy Scale, which provides a running average. Then, I enter that average weight into MFP. I like this method because it really allows me to see if I'm trending up or down over time and it also accounts for the daily fluctuations (I can fluctuate by several pounds day to day depending on a number of factors).

I weigh daily and log into an app to see the treand. I use Libra. I only log new LOW weights into MFP.

I weigh daily, first thing, naked, same place every day. I track weekly. I don't care about the fluctuations and focus on my trajectory. there are apps online that smooth out the fluctuations for you if you want to track frequently and not go crazy.

I weight sporadically through-out the week and enter it into MFP because then it goes to fitbit then trendweight since I don't have a wifi scale. I have been losing weight slowly so I started using trend weight to make sure I was still on the right track. I always weight only in the mornings, same time to try to get a similar gauge on where I am. I don't get emotionally attached to the individual numbers because it can vary a lot depending on TOM, salt intake, sugar intake, exercise, not feeling well, etc.

I weigh daily to keep myself accountable and it sets the tone for healthy eating and fitness.

Weigh every morning and log it to MFP whether it's up or down. The daily weigh-ins help keep me on track, even when I'm going way off track. It's the same way that I log my food whether it's a healthy salad or a huge pizza followed by 2 bags of haribo. I need the routine, if I take a break even for a day or two I'm likely to give up completely.
I do also have an excel spreadsheet set up which tracks the weight and does a 7-day rolling average. I've got a plot of the daily weight, the rolling average and a linear trendline to prove that I'm still going in the right direction overall and give a vague indication of when I'm likely to reach my goal weight.
I do love a spreadsheet.
Way more sporadic with the measurements, if I'm losing weight I can measure a couple of times a week, if I've gained a bit then it can be a month in between measurements.

I weigh daily, ONE TIME per day, in the same spot, wearing the same thing. I update in MFP for each new low. I track daily in happy scale to see the trends and overall fluctuation.

In the beginning I weighed and logged every day. Now I do so once a week. Occasionally I will weigh myself the next day, just to see how certain food affects water retention.
