General Diet Plans and Questions - For Everyone Who Has Asked When to Weigh...I did an experiment

I've seen this come up a few (or a ton) of times since joining 3fc, the question: when is the best time to weigh yourself??? So, just as an experiment, I decided to weigh myself many times over the course of the day last week cuz I was watching my niece at my house. I weighed myself first thing, then after eating, after using the bathroom, etc.

-First morning weigh in, after going pee, no clothes: 137.5
-After getting dressed, having oatmeal, 12oz coffee and three cups of tea: 142.4
-Used the bathroom: 141.3
-Had three more cups of tea and a fruit and nut bar: 143.2
-Peed: 142.6
-One more cup of tea: 143
-Peed again: 142
-Took clothes off to see how much they weighed: 139.8 (so, 2.2 lbs)
-Clothes back on (same ones), had one cup of tea, a plum and a luna bar: 143
-Peed: 142.6
-Ate a few bites of spaghetti and maybe 5oz of water: 142.8
-Peed (I swear I don't normally pee this much): 142.4
-Went on a half hour walk, ate a mini bacon cheeseburger (extra tomato) and a cup of water: 142.3
-Peed 141.9

went to bed

-Weight the next morning, no clothes after peeing: 137.3

It may seem like a silly experiment, but I hope it is helpful for people who do weigh at different times or with clothes on to realize what a difference it makes. Over the course of the entire day I "gained" 5.7 lbs, even if you subtract the weight of my clothes (2.2 lbs) you could say I "gained" 3.5 lbs.

But the next morning, which is when I always weigh myself, I was down 0.2 lbs, not a huge loss, but a loss nonetheless.

Just thought I'd share.

This cracked me up! Sadly, though, I do this on an everyday basis :^: I'm constantly curious what the scale will read, especially after I pee. :D I know, I'm such a loon!

Thank you for sharing! I when I think about I think I pee as much or more throughout the day xD hehe.

I do daily weigh-in's in the morning, after peeing and I weigh with no clothes as well. I used to weigh-in throughout the day but its way too stressful.

Thanks for sharing the results of your experiment! It helps to see just how much weight we "gain" and "lose" during the course of the day. I should try that too.

I wish my body woke up a little earlier than my brain instead of vice-versa. Every morning I weigh myself after peeing, but before drinking any water. I look at the scale, mutter something rude under my breath or say "yay!" accordingly, and shuffle off to fix and eat my breakfast. Only then does my body decide it has...shall we say, unfinished business to attend to in the bathroom.

Hel-LO, body, couldn't you have decided to do that twenty minutes before breakfast so I got a nice low number on the scale? Grr! :D

(And I apologize about that TMI, but really...every freakin' morning this happens!)

Thanks for sharing your experiment. This may help someone to realize the importance of weighing in at the same time on a regular basis.

One question though...did you really eat a bowl of oatmeal, a couple of luna bars, a few bites of spagetti, a plum and a "mini" cheeseburger all day? If so, this may be why your body retained water (5+ lbs) the way it did. It would have been virtually starving and consequently your test may not be as effective to someone who eats a balanced diet sufficient in calories.

Just thought I'd point that out to anyone wondering if they may actually gain 5+ lbs within the same day.:)

I guess I should have been more specific. My oatmeal had berries (fresh ones) and nonfat plain yogurt mixed in it, later i had a fruit and nut bar, Luna bar, plum bites of spaghetti, my tea had an ounce or two of nonfat milk in each cup and the "mini" bacon cheeseburger is still pretty large. I got it at Kidd Valley and their regular burgers are about the size of Red Robin's burgers (so way bigger than anyone should eat in one sitting). So what I got was called "mini" but is still bigger than what I would make for myself.

My calories for the day were over 1400, so I would be pretty surprised if my body was holding on thinking I was starving.

This is also not how I usually eat, but I didn't have a carseat, stroller or carrier for my niece who is too little to walk, so I was not able to go to the grocery store. My only options were what I had at home (not much). And after my stepsis picked her up is when I got my burger.

I'm guilty of weighing myself a few times a day just out of curiousity, but my morning weigh in after a bathroom trip and in just my bra and panties is what I record. Too cold to weigh naked lol.

Thank you for posting your results!...I must admit that I weigh myself frequently during the weekends (because I am home and around the scale) and once in the morning everyday possibly twice if I do it again once I get home :o I guess I am obsessed...and I have noticed similar results to yours...I tend to "gain and lose" a couple pounds a day :)

Thanks. Your experiment made me giggle.
It is really interesting to see. I've been hopping on and off throughout the day. At one point, for some reason, late at night before bed I was getting the lightest weight.

Generally now I don't bother too much with it, as long as the general range is going down then that's a good thing.

Great and enlightening experiment! I always weigh in the morning, after elimination, in no clothing or a thin nightgown. I weigh myself on average about once a week, maybe more than that if I've lost (just to be "sure" it was a loss).

Thanks for sharing! I think I'm going to try this and see my fluctuations throughout the day.

thanks for posting glad i am not the only one... those 5-7 lb swings can be depressing and defeating...
i try and weigh in around the same time now.

I've done very similar experiments with all manner of food plans, all times of month, and different levels of water retention for different reasons, and I can tell you that with a "balanced diet sufficient in calories" the weight fluctuations actually tend to be greater, not lower, because healthier and more wholesome foods are heavier because they contain more water and fiber.

The weight fluctuations are caused mostly by the weight of food and beverages. Once they enter your body, they show up on the scale until they can be removed through urine, feces, and to a much lesser degree sweat and other body fluids.

The healthier your diet, the more your food weighs. You tend to eat more volume, but fewer calories (but the scale doesn't weigh calories, it weighs pounds/kilos). You also tend to drink more (this isn't always true, but for me it tends to me). On a healtier diet, you probably will poop more often, which can in the long run, lessen fluctuation (if you poop once a week, you're going to weigh the most right before you poop).

Because I weigh more than twice the OP, my fluctuations also tend to be twice hers. This morning, I weighed 309.8 and just now I weighed after a nap and weigh 311.4. I haven't changed my ticker, because it's PMS/TOM, and it's not unusual for me to gain 10 lbs in water weight during my period, even if I've been perfectily on plan, and this week I have been.

I can't wait to see how much weight, my period is masking. I know from experience that at this stage of my monthly, and with what I've eaten today, I'l likely to wake up three or more pounds thinner tomorrow (I'm also likely to be up all night peeing).

It's also why I don't change my ticker upward, unless I've gone more than 10 days without seeing that weight on the scale, especially when the gain is due to pms/tom weight gain or a high sodium day.


My weight fluctates more during days in the summer than the winter (in part, because I eat far more fruits and vegetables, in part because I drink more water and exercise more).

When I exercise, my weight fluctuates more. It goes up as much as 4 lbs the day after exercise, and a couple days later those extra pounds (and sometimes a little more, yeah) will be gone.

If I eat very low carb, it usually drops quickly and then fluctuates less (probably because I retain far less water). Eating low enough to minimize my wieght and minimize the fluctuations has no great benefit that I can see. Eating no fruit, starch, or veggie servings may minimize the fluctuations in the short term, but in the long term moderate carb (the diet I try to stay one, because while I lose faster on very low, I feel better physically on moderately low-carb).

On Tuesdays (my TOPS weigh-in day), I tend to intentionally eat lighter meals (in weight) and drink more fluid until about 2pm and then no fluid until after my weigh-in at 5:15. There's not a really good reason, I just want to be at my lowest possible weight for the weigh-in. It's silly, but I like to stay as close to my morning weight as I can for the weigh-in, without fasting all day (which is what I would do in the bad old days of disordered eating).

It's the only day I try to limit the fluctuations (and it's for a somewhat foolish reason), and in general the healthier I eat, the more fluctuations during any given day. If I don't take in enough fruit, vegetables, and water, I will end up pooping less, but there is still less variation during any day, except the days I poo.

Fluctuation isn't something to be afraid of. And a great deal of fluctation isn't necessarily a bad sign, it can be a very good one. In my experience, the better I eat and exercise, the more fluctuation I experience, not less. To assume it's a bad thing and to aim for little or no fluctuation could lead a person into some very unhealthy habits.

Love the experiment, Tattoodles! That was really interesting, thanks for sharing!

That was a great experment! Although if I had done it I most likely would be freaking out with the gains during the day then the uncertainty that the scale would be better in the am.

I tend to weigh myself mid week and on weigh in day first thing in the morning before I dress. sometimes mid week will show a loss only to show no loss on actual weigh in day which makes me crazy. Not sure how to slove that mystery :?:

Hey tattoodles thanks for sharing!

I'm really interested in the fact that your weight fluctuated 3.5 lbs overnight. I imagine this represents a typical day for you? I weigh myself in the AM and PM too, without clothes, etc, and my difference is never more than 1.5 lbs. Our height and weight are not that different, so I'm curious if anyone has a hypothesis for this!

Just goes to show how every body is different :)

This is GREAT to show newbies and even veterans how the silly numbers on the scale rule us, and for what reason? :P We must be sadists. Every time I weigh myself after I've consumed something my boyfriend asks, "Why are you doing that AGAIN?" And I tell him because I like to see how the numbers will change. To which he replies, "No you don't, you HATE when the numbers change because they're normally going up!"

It is curious to see how they jump all around, I can't help it!

I agree with you kaploids! I have battled this my entire life. All of the women in my family have had gastric bypass or the lapband. Morbid obesity is prevalent, and several family members have died from complications related to obesity. I have found what you are saying to be true. I used to obcess about the scale. It doesn't give the true picture of what is happening always. I weigh daily, as an accountability to myself (I love to pretend I haven't eaten things!). However, the only number that I record in my journal is the weekly number. Daily weights are very misleading. Thanks for sharing, and reminding me about the importance of remembering to apply what I know about my body after years of this battle. Take good care, and keep on losing!

Good experiment. I am curious to know what the affects of working out have on weighing in. Whenever I have weighed after working out, I was always heavier. Could it possibly be due to all the water I ingested while working out?

Great experiment! Thanks for posting this. I am relieved to know that I'm not the only one who can gain 3 lbs in a day and have it go back down the next morning! I have a tendency to become obsessed with the scale and be too hard on myself. :(

I also am heavier after a workout, so another concern of mine was answered here as well, thank goodness for this thread.

:D

The reason for your little problem each morning is the gastrocolic reflex. After eating, stomach distension stimulates colon contractions which makes you want to use the bathroom.

Nola I am the same way!!! I can never get an "accurate" (er... LOWEST NUMBER POSSIBLE) weigh-in because of this. Kellyg thanks for the explanation, I've always been curious!

No problem...I found it interesting when I learned about it. There's also a second reflex where moving in position from supine (laying down in bed) to standing up stimulates colon contractions...which is why most people are morning pooers (forgive me if this is tmi). But sitting down straightens the rectum and releases the muscle contractions of the anal sphincter so it's harder to use the restroom while standing, if anyone was ever planning on trying that. :)
