Why do you weigh less in the morning?

You would think the problem is simple: Why do you weigh more when you go to sleep than when you wake up? Because you are doing so. Somehow you’ll wake up lighter while doing absolutely nothing all night but sleep.

It’s not about toilet stuff. And when you go to the bathroom, if you wake up and weigh yourself, you will always be lighter than when you went to bed. Why? For what?

My first thought was “sweat.” Maybe when you sleep, you sweat, and some of your water weight can vanish as water vapour. This, it turns out, is real. That’s part of the statement — but not the fascinating part.

This is because you’re still alive! The chemical reactions that sustain you all require energy and even if you don’t eat in your sleep, these metabolic processes still convert glucose molecules into carbon dioxide ( CO2) and water. The air you breathe out is 4% CO2 and water vapor is polluted. You’ll exhale 2.100 liters of air in a typical eight-hour period, containing 27 g water and 84 liters of CO2. The carbon weighs 42 g in CO2.

While 69 g doesn’t sound like much in a night, you often lose weight from your sweat, the saliva that you dribble onto the mattress, and from the flakes of the skin you shed onto the sheets. This is why every now and then you need to change the bedding. A little does add up.

If you are thinking that sleeping more is the way to lose weight, good try! The truth about your weight is that just from what you eat and drink, as well as your daytime activity, it can differ a lot. So, if you take your diet seriously, and use your scale to help you track your progress, here are a few things to keep in mind.

Seek finding one that has a strong reputation for being accurate. You might even want to consider getting your body weighing a scale, your water content and your body composition. These scales can be a little more expensive, but they can give you a much more accurate picture of whether the pounds you seem to have lost overnight are actually fat loss, as opposed to water weight.

The safest time to weigh yourself is normally on an empty stomach in the morning, because your body is in a relaxed condition, because you have generally had nothing to eat or drink for a few hours. Bear in mind what you may have done to your body the day before, because the number you see on the scale may be influenced.

No matter if you weigh yourself, don’t be freaked if you notice your weight went up one or two pounds one day and down the next. Your  weight is very variable. Yet whether it’s going up and staying up, or vice versa, you know things change. The scale number can be used as a relative number and is not absolute.
