For Daily weighers....

lol I am obsessed with weighing myself unfortunately and I usually gain anywhere from 1-3 lbs throughout the course of the day. By bed time, usually 1-2lbs up and in the morning i have lost 2-3.

Out of curiosity I've started weighing myself just before I go to bed to compare to what I weigh when I wake up the next morning. It's been anywhere from a 2.5 lb difference to 4.5 lbs. So far I've not really gotten a consistent number, but the average is 3.3. I was hoping I would get a consistent number so maybe I could anticipate what I'd weigh the next morning, but so far no go.

A couple of times I've also weighed myself in the middle of the day, again, just out of curiosity. The most difference I saw there was about 5 lbs from that morning.

Not at all necessary to my records, just another number that's fun to keep track of It also helps remind me that weight fluctuates CONSTANTLY - and not to take slight increases seriously.

Several pounds up and down all day. I drink a lot of liquid in the morning, and I can gain several pounds before lunch. A couple of visits to the bathroom and I pee away the pounds! Overnight, I can lose as much as 4 or 5 pounds, depending on what I ate for supper and how quickly my body breaks it down.

Agree with beaytyandtheb, I drink a ton and most of what I eat has a high water content too.. And a lot if it, also the salt thing. Usually I'm 5 or even 6 lbs higher than the morning...

i'm actually the opposite of most, i think. i tend to weigh less at night, after work and the gym, but before dinner.

i tend to eat very scantily during the day, usually a luna bar, an apple and non-dairy yogurt until about 9pm, depending what time i get out. i hit the gym after work then weigh when i get home, then eat the majority of my food for the day. i'm typically 1-3lbs heavier the next morning but that's to be expected. i do realize the weight i records for the day is after eating little and being dehydrated but as long as it remains on a downward trend i'm good.

If I go to buffet for cheat meal that means at least 8 between 11 lbs. On regular day I drink 4-6 liters water. Goes around 4-6 lbs. I've never checked salt - sugar difference. I should find out that. Thank you all for comments

I weigh every morning and have seen gains of 5lb in a day or 8lbs over two days - boy that was a great weekend!!
Over a week I've gone from 168 to 176 and back down to 167......

When I've weighed other times of day then it's clear my lightest is in the morning.

Apart from sodium, alcohol also seems to cause a temporary bloat.

My weight has always swung around rapidly, a 5 to 7lb gain for even a really active week on holiday is normal for me and it only takes a couple of weeks to get rid of it again. I've also been following an uneven eating pattern (5:2) for the last 18 months which contributes to fluctuations as well.

I think the advantages daily weighing gives you is the understanding that weight =/= fat and weight is not a constant.

Yesterday I weighed myself mid morning I was devastated I was up 6lbs! When I weighed in as soon as I got out of bed I was down 6lbs.

most of your overnight weight loss is water loss, don’t discount the loss that comes from the energy you burn while you are sleeping.

While you sleep, your body processes the food and drinks from the day before. They are broken down and eliminated through respiration, perspiration or urination.

overnight weight loss is a combo of
(1) water lost via the skin and respiration
(2) basal metabolic caloric expenditure
(3) urine loss in the morning. Water loss, excluding urine and feces, accounts for over 80% of the weight lost while sleeping.

Consuming too much salt is a factor in weight gain and water retention. If you spend your day eating salty foods, by nightfall you may look puffy and bloated. Sleep gives the body an opportunity to balance itself causing much of the water retained to be processed and eliminated. Comparing your appearance after a day of loading up on salt with your refreshed morning look exaggerates the slimming effect.

I don't weigh myself at night, but I appreciated reading this thread. For some reason, I became very sodium sensitive this week. My weight was up eight pounds. Sodium is killing me for some reason even though I have never had a problem before. I can't even get my wedding set off in the mornings.

Losing 1-1.5% of body weight (fluid loss) during exercise is fairly normal. One has to keep an eye on their fluid intake before, during, and after exercise. Weighing before and after is a simple way to regulate how much water you have lost. Waking up the morning weighing less than before you went to bed usually is related to water loss during the night (sweat, urination, using the toilet). Again - it's very normal.

Symptoms by percent body weight water loss:

PERCENT WATER LOST

---

SYMPTOMS
0% --- none, optimal performance, normal heat regulation
1% --- thirst stimulated, heat regulation during exercise altered, performance declines
2% --- further decrease in heat regulation, hinders performance, increased thirst
3% --- more of the same (worsening performance)
4% --- exercise performance cut by 20 - 30%
5% --- headache, irritability, "spaced-out" feeling, fatigue
6% --- weakness, severe loss of thermoregulation
7% --- collapse likely unless exercise stops
10% -- comatose
11% -- death likely

I find the fluctuations fun! I can gain as much as 3 lbs. in a day. I really get a kick out of weighing myself right before and after a bowel movement. It actually keeps me sane. So I know that I am only fluctuating. I wont count a loss/gain unless it sticks throughout the day for 5 days or more.
