bra or time of day?

Definitely the end of the day affecting things! You should weigh yourself first thing in the morning, after you pee. Gravity's gonna pull the weight from your boobs down with or without the bra!

As a general rule, normal people are lightest in the am. You sweat and don't drink at night, so you're the lightest you're going to be. I have known of 1 person who is heaviest first thing in the am though, which doesn't make any sense to me, but I saw the scale, she wasn't making it up!

Full bladder/ colon will have more effect at the end of the day than a bra.
Always wrigh first thing in the morning after u pee.

First thing, wearing a bra does not make you lighter the weight of your boobs are still there, bra or no bra.
Secondly weight fluctuates all day. Like others have said if you are going to weigh, weigh in the morning naked and after you have used the bathroom and end it there, do not weigh every time you pass the scale the number will always be different.

My opinion, taking measurements is way better than weighing on the scale.

weight one day fully dressed 210 next day I weighed myself before bed with out a bra this time bc hey bed 213.8 could it been the fact that the bra was off allowing my 42 fs to weigh me down or just the end of the day causeing me to freak?

It's probably just a daily am/pm fluctuation, I wouldn't worry about it.

Actually, it depends a lot on what kind of person you are - if you tend to obsess too much about your scale, then the best thingwould be to just weight yourself once a week - say, Friday morning before getting dressed. Another approach that you can try is actually weighing at the same time of the day, every day, and recording it on MFP. You know, the good, the bad and the ugly. This will give you scientific proof of the bodily fluctuations per week and per month and you'll be able tp pull out the graph over your last 30 days and your last 180 days etc. As long as the overall trend is where you want it to be, a little fluctuation is no big deal

Also, for me, *usually* I'm about 1 lb lighter in the morning than I am in the evening; but it does happen every now and then that I'm heavier in the morning. No idea why, although I suspect sodium.

Did the cups have helium balloons tied to them, lifting the breasts into the air, so that they wouldn't register on the scale?

Punctuation and capitalization are your friends.

Depends... does your bra have straps that attach to the ceiling or something? Bras do not make boobs weightless!

Your bra has nothing to do with it, although the doctors say being fully clothed adds about 3 pounds. I always weigh myself naked (or just underwear) in the morning.

Um ...

if you have a 5 pound bag of flour does it weigh differently if you're holding it by your hip or over your head? Will a 5 pound bag of flour weigh 3 pounds when at your hip, 5 pounds at your face, and 7 pounds overhead (or in reverse)? Think about it . . .

I think standing on one foot will help, you'll weigh a ton less! (and in case you didn't catch the sarcasm there...whether your boobs are tethered to your chest or hanging loose, they are not going to affect your weight)

Weigh yourself at the same time every time, once a week is best to see results and not watching fluctuation every day.

i just get someone to hold mine.

I weigh naked and hold my boobs up with my hands. Now tomorrow I'm gonna use one hand for this and with the other hold up my left butt cheek. I predict a 7.5 lb weight loss.
