Weigh day

Weighing daily is fine as long as you're aware that you'll see more ups and downs. The only thing that matters is that you do it under the same conditions (first thing in the morning usually, after using the bathroom and before consuming anything, wearing the same amount of clothing).

It is all up to you hun, I weigh every morning, but be aware that you will see your weight go up and down, don't panic just keep going.

You can do it after you have gone to the bathroom, and preferably with no clothes on to get an accurate measure, I would suggest take your measurements as well, sometimes you will loose cm and not pounds.
Good luck and keep us posted with your progress.

I log once a week first thing in the morning. I use the restroom first, and weigh with no clothes on...I even take my fitbit off! HAHA! Probably a little extreme, but I have a lot of weight to lose, so I want it as accurate as possible. I definitely agree--take measurements! There are weeks that the scale doesn't move a pound, but I know that I ate within my calorie limits and I got my workouts in. Lo and behold, clothes are looser even when the scale doesn't budge.

Best of luck to you on your health and wellness journey!

I weigh daily and plot it on a graph so I can see the trend. I use Friday mornings as my MFP check-in, though. If you don't think you'd be disappointed with daily fluctuations, then weigh daily if you want. It's quite personal to be honest.
