Why do I weigh less in the morning than at night?

Question

I’ve been working out and dieting to try to lose some weight and get healthier. Part of my routine to keep me motivated is to weigh myself when I first wake up and then again right before I go to bed every day. After the first two weeks, I noticed that I usually weigh less in the morning than I do at night, which surprised me because I figured I’d weigh less after working out and running around all day. What causes this to happen?

Answer 1

Your body fluctuates in weight all day long, and it’s not unusual for it to shift about 2-4 pounds at any point in the day. Part of this is because it depends on what’s going in and out. If you weigh yourself after you just finish eating lunch, then it’s likely that you’ll notice a few extra pounds because of the extra food weight. You’d be surprised how much weight you actually lose after using the bathroom with a super full bladder. We joke about it, but all of these things really do make a difference. Your body’s level of hydration as well as how much you sweat is a contributing factor to weight fluctuation too. So if you sweat a lot at night then you might notice some weight loss in the morning from all that liquid leaving your body. I hope it explains why you weigh less in the morning than at night.

Answer 2

You weigh less in the morning because sleeping causes your body to rest without food or water for a pretty long period of time. Think about all the activity you do and how much you drink and eat all day long compared to the very little movement and lack of any ingestion for multiple hours back to back while sleeping. This also makes your weight in the morning your truest body weight because all the food you’ve consumed has been digested and most of the fluids have been absorbed.

Answer 3

It’s actually been proven that the amount of breaths we take at night result in some weight loss due to expelling carbon from our body. If you take the weight of carbon and calculate how many steady breaths someone takes while sleeping, enough carbon is being exhaled to result in a few hundred grams worth of weight. Not that this makes a huge difference in your total weight, but it’s there enough to make a visible routine difference.

This is kinda new to me as to why do I weigh less in the morning than at night.

Answer 4

The reason why you weigh less in the morning than at night is because you haven't eaten or drank anything yet in the morning. Don’t weight yourself too often, it will only drive you crazy!
