An Important Fact about Body Weight

Have you ever tried checking how much you weigh at different times in the day?

Most people that do will come to a realization. It is that how much a person weighs is not static. However, the difference will only be slight as it will increase or decrease by just a few pounds. At least, it is not enough to cause extra weight on your face.

In light of this, the question for the most part is why the variation in body fat. This will be discussed in the next part of this article. You will figure this out as long as you keep reading.

Reasons Why You Lose Weight over the Night

If you are in the habit of checking how much calories you gain or lose in the morning, here is something likely to happen. For the most part, you will realize that you weigh less in the morning compared to a different time of the day. Listed and explained below are the reasons for this:

Slower Metabolic Rate

To put things in the right context, most of the other reasons are tied to this one reason – slower metabolism. By nature, the demands of sleeping mean that your metabolic activities are slower. So while you sleep, the calories consumed are not quickly put to use by the body. This means additional body fat which translates to an increase in the amount of weight.

Amount of Water in the Body

Reasons Why You Lose Weight over the Night

Water accounts for a large chunk of what makes up a person’s body weight. So, it is simple logic that the amount of water in the human body contributes to how much a person weighs on the scale.

The moment you retire to bed and sleep sets in; it is most likely that you lose more water in the body. There are two ways this could play out. The first way is through perspiration. This is especially when the temperature necessitates this.

The second way is through urination. This is especially for people that are advanced in age as studies have shown.

Loss of Carbon in the Body

How carbon contributes to weight loss at night is quite interesting but logical. For starters, carbon is made available in several forms. Food is one of the major forms. This is because many food molecules that we eat are rich in carbon. We are talking about food options like fats and carbohydrates.

As carbon is let out of your body as you exhale air (even while you sleep), it will help rid your body of some things. These are waste products as well as water vapor. Seeing how water contributes to weight, you can figure out the relationship between carbon and weight loss.


Appropriate Weight management is important for healthy living. This is why you need to maintain a weight range that does not threaten your health. In the spirit of keeping you informed, this article has discussed reasons why what you weighed a short while ago might be different from the current ratings on the scale.
