why weight goes up after eating


Quote  |  Reply

It may sound liek a dumb to question to some of you but seriously, why is it I weigh myself before eating and when I am done I have gained like 4 pounds.  Is it really possible I just ate 4 pounds of food?  This is like everytime I eat too not just after a big meal or holiday dinner.

Your new weight is your old weight + the amount that you've just eaten.  If you step on the scale with your dinner.. you should weigh that much after you've consumed the food.

For instance I weighed 141 today before dinner at a half of a subway sub and a glass of tea. weighed myself and I was 145.

I know subway does not weigh 4 pounds.

No but scales are inaccurate..sometimes by up to 3-5 lbs. They are only useful for watching long term trends..which is why most people advise to weigh only weekly.

I really find weighing at least once daily helps me stay on track, maybe I'll just avoid doing so after meals but I am still lost on why it does this to only me, I have had my kids do it and it increases maybe a pound or two but for me it's always at least 2-4 pounds.

 

Plenty of people weigh daily (here's a site that explains at least my reasoning for daily weigh ins - http://www.myjanee.com/livelight/eat/weigh.ht m)

However, you shouldn't weigh yourself multiple times per day - always at the same time in the same conditions - I find it easiest to do it in the morning, after the bathroom, before showering. Any other weigh-ins should be done purely out of the joy/torture of seeing how crazy your weight can change within a short time, for no good reason.

Also, I'll be honest - when I see the number on the scale, it is just a number to be logged and added to the hundred other numbers - it has very little to do with how much weight I've lost, at least on a small time scale. I usually know what I was yesterday, and have an idea of the past few days, but I've actually trained myself, through daily weighing, to not think of it as "I gained a pound since yesterday" - instead, my thought is "I weighed in higher than yesterday - probably my salty dinner - I'll try to drink more water today." When it goes back down the next day, I didn't "lose weight" - I just weighed in lighter - if a few weeks go by, and it keeps getting lower, then I am actually losing weight. I typically don't say I've lost weight until I see a number that reflects a good 5 lb loss.

Remember, though- that Subway sub and drink weighs not only its intrinsic weight, but all the bread soaks up liquid like a sponge.

For a comparison, do a liquids only day.  I do them two times a week, and it is great as long you make sure to get enough calories.  Weigh yourself the next day, and then eat normally.  When you weigh in the next morning, you will see just how much the food adds to your weight.

And here is a site that explains why not to freak out if you are the type to weigh every day.  I'm not saying DON'T weigh every day -- just remember that fluctuations abound and it is not worth it to get upset over every change up and down.

 I do this too.  I weigh in first thing in the morning after using the restroom, and then I weigh in at the gym, after changing into my gym clothes (before putting on my shoes and without my jewelry) but I do this as a way to make sure I'm staying on track.  It helps me have more control over my daily calorie consumption.

coach_k, I think amethystgirl also went further on to explain that she doesn't freak out when she weighs every day about the fluctuations. For those of us who weigh daily (I'm another one who does), we log the numbers daily and watch the overall trend. I may weigh more tomorrow than I did today--no biggie, might be because I had a lot of salt and retained more water than I intended to. I might also lose 2lbs between one day and the next. I don't get too excited about it because I realize that most of that weight, if any of it, was water weight, and that I might gain it back tomorrow once I better hydrate myself.

A lot of people put too much weight in the daily numbers. I weigh daily to keep on track, but I only compare the numbers from the week before. Last Friday, when I started on calorie count, I weighed 226. I weigh 223.6 today, a week later. So I know I've lost weight over the course of the week, though the scale went between 225 and 224 a lot, and I broke into 223 today. Though I'm weird, since I know scales aren't completely accurate, I weigh myself several times in quick succession, add the numbers together (today's numbers were 223.6, 223.6, 223, 224, and 223.8) and divide them by the number of times I weighed myself to get an average weight. My actual weekly comparison day are Mondays, however, so today's weight isn't going to be put down in my journal.

However, everyone does things differently. What works for one person might not work for others. I would drive myself nuts if I weighed weekly; I like keeping track in a daily fashion. Others might find the numbers zig-zagging on a day-to-day basis to be too much for them, and weigh themselves weekly instead.

armandleg -- I never suggested that amethyst girl DID freak out.  I posted that because 100s of people on this site DO freak out when they weigh every day.  It is in the forums once, twice, too many times daily.

It is not for me to decide that daily weighing is good or bad for YOU -- I am simply passing on information to help people make a decision based on both sides.  Many people can weigh daily and handle the fluctuations without meltdowns -- unfortunately many cannot.

 I weigh myself several times in quick succession, add the numbers together (today's numbers were 223.6, 223.6, 223, 224, and 223.8) and divide them by the number of times I weighed myself to get an average weight. My actual weekly comparison day are Mondays, however, so today's weight isn't going to be put down in my journal.

 

 I use to do that too!! I DID eventually have a freak-out though, my boyfriend performed a scale intervention, and I hid the scale under a pile of blankets at the top of the hall closet and promised to only use it once per week.

I must confess i am back to daily weigh-ins, and only get on twice if I totally don't believe the number (today it said I was down 4 lbs from yesterday, so I tried again and it said down 2, which I find more believable, and it's only that much because I am coming off my period so the water retention is dropping away). I do it because i find it interesting to watch the patterns, but don't put any stock into it as being at all accurate...I have accpeted that my scale itself fluctuates within about 4 lbs, and my body fluctuates too. Tracking on a weekly basis, officially, is much more satisfying anyway...15 weeks in and I have gone down every week! 

As to why you would consistently gain 4 pounds after eating only, say, one pound worth of food...I dunno. Are you accounting for any liquids you drank between weigh-ins, because water is very heavy. Are you weighing directly before and after eating every time? I am always heavier in the evening than in the morning, so I stopped looking at the evening weight alotegether, it seemed pointless when I knew it would be lower in the morning.

Maybe the sub ... reproduces? Just an idea...

i really like your idea moskovite82.  i wouldn't feel so abnormal if it was just the subs fault.

 

victoriagirl  I really have given up trying to understand my body.  I guess that sums it all up.  I am really trying to only weigh once a day, in the morning (or evening for me since I work midnights) and use that number as my motivation for the day.

Thank you all for the feedback

You wouldn't weigh yourself while you were holding a sub in your hand. You're still holding it in your stomach. 

I guess alot of you are missing my point this happens even if I only ate a salad.  Am I the only one who has ever tried this experiment?

Sigh.

1 gallon of fluid weighs EIGHT lbs.

If you drink tea, then have a full cup of tea refill, then you've just added about 3-4 'lbs' of water weight to your body.  This is not loaded with fat and calories, and goes away over the rest of the day as you pee it out.

a 32 oz cup is, 1/4 a gallon of fluid.  2 of those is 1/2 gallon of fluid = 4 lbs of liquid 'weight' added to your body.

My scale is in my upstairs master bathroom. I weigh in the morning and then I weigh before bed. Otherwise I have to hoof it up the stairs, take my clothes off, etc etc. It's just totally not worth it to me. Tongue out

Are you drinking alot of fluids when you eat, because that can put the weight in your stomach.

 I did this all the time when I was wrestling competitively, immediatley after you eat/drink something you're weight will go up by the weight of whatever you just ate/drank.  It isn't possible for your weight to go up more than that unless you live in some parallel dimension where the laws of physics don't apply, or you're scale isn't very accurate.

Try weighing yourself, go away, come back and weigh yourself 10 minutes later. (Without eating or drinking in between).

If you have a cheap scale like I do, I bet you get slightly different numbers.
