How often to weigh?

twice a day, most days.

I'm not gonna lie. I jump on the scale at least once a day. Usually first thing in the am right after the bathroom. Sometimes it's more, just because I'm curious of how different things effect my body. I usually log it ever 3-4 days. I try to only make an official weigh in on Tuesday mornings, and then leave the scale alone, but I haven't been able to do that just yet. It was exciting to see that big drop off this morning. I can't wait to see if it's gonna stick around or not.

Every morning but I don't take any notice of weight only trends over time, if your going to panic if you gain a kg do it weekly or monthly!

I like to weigh myself daily becauseI like to see how what I did the day before makes my weight fluctuate (because I'm a nerd) and I log it on paper with a big circle around the date and weight when I hit a milestone.

If fluctuating numbers on the scale are discouraging, I definitely would recommend skipping daily weigh-ins.

hourly. gives best results.

Much depends upon what you do with the information that the scale provides. To me it is just data and I have reprogrammed myself to not be concerned about the inevitable daily fluctuations that happen. Scale weight ofttimes makes little sense and body weight can alter by upwards of 5+ pounds on any day and at any given time of the day depending upon water retention, sodium content of recent meals, glycogen stores in your muscles , etc.

Once I realized the above then it's now cool to weigh myself daily and sometimes more than once daily as , for me, I can nerd out on trying to figure out what might be happening in my body by getting that extra data.

Before figuring that out it was very easy to get discouraged if the scale did not get lower EVERY time.

If not seeing the number ALWAYS in decline causes you anxiety then, yes, limit those weigh ins to 1 time weekly or even monthly.

I you are at peace with constant fluctuations then feel free to hop on the scale whenever you feel like it.

Once a week. I get too discouraged jumping on the scale once or twice a day and seeing the fluctuations. Based on past experience, I know that I will retain a lot of water the week before my period, so for about 10 days (which includes before and during my period) I will either not show a very big loss, or I will show a gain of up to 6 lbs, depending on whether I have eaten a lot of salt or junk before my period. It goes away when my period does, but it helps me to anticipate this gain when I weigh in, so that I am not discouraged.

As long as I am tracking honestly, getting exercise, and eating only up to my calorie limit, I know that I will loose weight, so for me, there is no need to weigh once or twice a day.

I record once a week. I actually weigh myself every time I go into that bathroom. Just to see the fluctuations, cause I think its interesting and it helps calm me down if the scale goes up sometimes, because I can see its normal.

Once a week for me... right now, first thing every Friday morning!

I try to weigh every morning because I have a bad habit of letting myself think I'm losing between weigh-ins. I need to be able to monitor myself every day. If my weight is up, it means I need to skip dessert and go for a smaller portion sizes. That said, I skip weigh-ins on mornings when my digestive processes are slow...if you know what I mean...and jump back on the scale the next day.

Every morning. Mainly because I don't trust myself and I think it keeps my eating in check. There is an app called Libra that I put my weight into every morning (just started 2 weeks ago) and it provides a graph of my progress. I think it has really helped me! I've been on MFP since the beginning of this year and I am barely losing now because I am facing my weight daily and I know that I can't afford to eat like I used to. When I get to my goal- or closer to it, I want to weigh in weekly and then maybe monthly after that. I have gained 50 pounds within the last 5 years (20 in the last year) and I think a big contributor to that was never weighing myself. But that's just me.

I weigh & take my measurements once a week on Sunday morning.

You should only weigh yourself once a week since there can be a lot of factors to mess up daily weights, like salt and water intake. If you eat a salty dinner, then you can weigh more the next day. Usually you want to weigh first thing in the morning. I wait till after my morning exercise on Monday mornings.

I've always weighed every day. Sometimes twice a day. Sometimes even more than that. I'd tell myself, "I'm a smart girl. I understand nutrition and water retention and even glycogen stores and stuff like that. I can handle day-to-day fluctuations." But, then, even though I logically know that I did not eat 1450 calories yesterday and still gained 0.8lbs of fat, I found myself still getting really discouraged. Like, I'd even get frustrated about the NON-fat gains, like "I drank a TON of water yesterday, was under 100 carbs, didn't lift, had black coffee for breakfast and asparagus for dinner and didn't eat very much salt, I had a good poop, how did I STILL gain weight yesterday????" The more I educated myself about the whys of daily scale fluctuations, the more frustrated I got, not less.

So, this is brand new (like, as of Tuesday), but I'm hiding my scale for the next two weeks, and I'm hoping to move to a two week pattern. I do slightly fear that if I gained over this first 2 week span that I'll go totally and completely off the rails, but hopefully that won't be the case. We'll see if that improves my mental health any...I think once I make it through the first two week period it will be easier after that, even if I do eventually see a gain at some point.

Weigh as often as you like so long as you don't drive yourself nuts.

Ignore short term fluctuations regardless of whether you weigh daily, weekly, or something else.
