Why Do I Weigh Less In The Morning?

A lot of people notice that when you weigh yourself multiple times each day, you are a slightly different weight at different points during the day. 

Why Do I Weigh Less In The Morning

While, if you have accurate weighing scales, this number is unlikely to change significantly, however, it is normal to weigh slightly less in the morning than later on in the day. 

This change in weight from the morning, to later on in the day, is not really linked to your weightloss journey, but instead, it is linked to your bodily processes.

Let’s have a look at why you weigh less in the morning than later on in the day. 

Why Do You Weigh Less In The Morning Than Later On In The Day?

You may be inclined to think that if you weigh less in the morning, and more in the afternoon, you have lost the weight and then put it back on again later.

This is not necessarily true. Instead, during sleep, your body continues to digest the food that you have eaten the day before. Your body continues to function during sleep, and your digestion is one thing that continues. 

During sleep, your kidneys continue to filter out the fluids that your body doesn’t need anymore and the food is passing through your intestines in order to be excreted. 

In 7 hours, which is often the length of time that you are asleep for, your body should have filtered out any excess foods and fluids. Providing you have urinated and defecated, your body may appear to be lighter. 

Whether you are eating healthily or unhealthily in the morning, your body will then appear to have regained the weight. A glass of water often increases your weight by up to half a pound. 

Urination And Defecated And Your Weight 

Every time you urinate, you are releasing some water from your body. On average, this will mean that you are letting go of a pound of fluid.

It is recommended that you weigh yourself after you have urinated or defecated. On average, a bowel movement weighs half a pound, too.

Other Reasons Your Weight May Fluctuate 

When you weigh yourself, often you will find that your weight has changed slightly from the last time you weighed yourself.

If your weight stays lower then you are likely to have lost this weight, however, if your weight is fluctuating, there are certain things that may be causing this fluctuation. These include: 


Medication can have a huge effect on the speed of your metabolism. It can mean that you are processing food much slower than before, or it can sometimes speed up your metabolism. 


As we have discussed, water can make up a lot of your body weight. It is sometimes accountable for half of your body weight. Fluids do affect your weight, however it doesn’t relate to long term water gain. 


Alcohol can affect your weight because it slows down digestion. It takes more time to eliminate it from your body than other things. 


If you eat a meal that is high in carbohydrates or sodium, then you are more likely to feel bloated. Your body will also take longer to digest food like this. These foods lead to water retention.


If you are holding in your urine, this can add a few pounds to your weight. This will be released when you use the toilet.

Menstrual Cycle

You often retain more water during your cycle. This means that you will feel heavier during your period.

How To Weigh Yourself Accurately

If you are wondering why you weigh less in the morning, you should make sure that you are weighing yourself correctly.

This will indicate to you whether you are losing weight or not. Follow these steps below to accurately check your weight. 

Weigh Yourself At The Same Time Each Day 

It is important that you weigh yourself at the same time each day if you want to ensure that you are getting an accurate measurement of your weight.

It is a good idea to weigh yourself in the morning as this is when your food from the day before has been digested and your weight will be most accurate.

Your weight will fluctuate throughout the day, so the morning is the best time to weigh yourself accurately. 

Same Variables 

Make sure that you weigh yourself in the same way each time. For instance, if you usually weigh yourself naked, make sure to do this every time.

If you weigh yourself before you eat, then keep this variable the same too. This is because all of these things have a big impact on the result. 

Use The Same Scale 

It is important to use the same scale that you have been using to ensure that you can compare your weight accurately. Not all scales will be exactly the same or show exactly the same results. 

Don’t Get Too Stuck On Your Results

While everyone’s weight loss journey is different, and everyone is undergoing weight loss for different reasons, it is very important that you don’t get too stuck on the result on your scales.

Some natural things will mean that you weigh more than other days, for instance, your period can mean that you retain a lot more water and will, therefore, weigh more. 

Ensure that you are losing weight healthily and that you are following a healthy lifestyle rather than being too focussed on every pound that you lose. 

Final Thoughts

So, sometimes you will weigh less in the morning than you do later on that day. It is recommended that you weigh yourself at the same time to make sure that you are taking this into account.

It is also not necessary to weigh yourself multiple times a day, because you will rarely see any significant differences in weight throughout the day. 

Make sure that you are undergoing a healthy weight loss process. It is important to maintain a healthy lifestyle, and your weight loss will come gradually.
