Why do you weigh less in the morning? Weighing less in the morning is a phenomenon that has been noticed by many people and is believed to be due to various factors. While some of these factors are relatively straightforward, such as the weight of clothing and other items left behind at night, others may be related to more complex body changes during sleep.
Here, we will discuss the possible causes for why do you weigh less in the morning and explore how understanding this phenomenon can lead to healthier lifestyle habits that can positively impact our overall health.

Overnight dehydration
A person usually weighs less in the morning than at any other time of the day due to several factors. One of the main reasons is overnight dehydration. During sleep, the body naturally loses moisture through breathing and sweating. This can lead to a decrease in weight as water makes up a large percentage of the human body. Additionally, during sleep, people are not taking in additional food or fluids so their bodies do not retain as much water.
Reduced food intake
Another reason someone might weigh less in the morning is reduced overnight food intake. When people go to bed without eating anything, the body does not have access to the extra calories and nutrients that those foods would provide, leading to a reduction in overall weight. Although these changes are small and temporary, they can contribute to a lower morning weight. Ultimately, a person’s morning weight will depend on many factors, such as what they ate before bed, how much water they drank, and how active they were during the day.
Loss of bodily fluids
One important factor is that we lose bodily fluids throughout the night while we sleep. We also excrete waste products during sleep, such as urinating and breathing out carbon dioxide, both of which reduce our body weight. Additionally, after eating food or drinking liquids during the day, our bodies temporarily gain weight from those substances. This means that when we wake up in the morning, much of that extra weight has been lost since most people don’t eat or drink for several hours before bed. This can lead to a significant difference in our body weight between morning and evening.
Excretion of waste products
Next, our bodies also excrete waste products such as faeces during the night while we are sleeping. These waste products make up a significant portion of our body weight and can have a noticeable effect on our overall weight when removed from our bodies. Therefore, fluid loss and waste removal can cause people to weigh significantly less in the morning than later.
Decreased glycogen storage
This is the reason why do you weigh less in the morning. Glycogen is an energy source derived from carbohydrates and stored in the muscle and liver as glucose. When you don’t consume enough carbs during the day, your body will use some of the stored glycogen for energy. This depletes the glycogen stored in the body, resulting in a lower weight reading.
Lowered salt levels
Another possible explanation for why people weigh less in the morning is lowered salt levels. Sodium plays an important role in balancing fluids and can cause a person’s weight to fluctuate depending on how much sodium is present. If someone has consumed a lot of salty foods during the day, their body will retain more water, resulting in a higher weight reading. However, if someone hasn’t had any salt-rich food before bed, their body will have time to flush out all that extra water and result in a lower weight reading in the morning.
Natural breathing cycle
The natural breathing cycle is a phenomenon that occurs when we are asleep: our breath rate slows, leading to decreased oxygen in the bloodstream and a decrease in weight. This effect is more pronounced in the morning because we are unconscious for an extended period of time during the night, and our body has fewer opportunities to intake oxygen. As a result, our bodies weigh less in the morning when compared to other times of the day.
Lighter clothing worn during sleep
Generally, people wear light, loose-fitting clothing such as pajamas or nightgowns while sleeping. Such clothing is designed to be comfortable and not add unnecessary weight or bulk to one’s body. Consequently, when individuals get up in the morning, their clothing contributes to a decreased overall weight. This can vary depending on what type of clothing is worn during sleep; for example, wearing a winter coat to bed would have the opposite effect.
Absence of food intake
Generally, individuals weigh less in the morning due to insufficient food intake. The digestive process of breaking down food and absorbing its nutrients causes weight gain throughout the day. During the night, while an individual sleeps, there is no food intake; thus, the body does not have new material to convert into mass. Consequently, this lack of food intake leads to lower body weight when weighed in the morning.
Natural metabolic fluctuations
Regarding the metabolic fluctuations at night, hormones such as cortisol, ghrelin and adrenaline play a crucial role. Cortisol acts as a “stress hormone,” which affects energy production by signaling your body to release energy reserves, while Ghrelin is known as the appetite hormone, regulating hunger and cravings. Adrenaline, on the other hand, triggers short-term bursts of energy. All three of these hormones work together during the night to cause a temporary decrease in weight, resulting in a lower weight upon awakening in the morning.
Final words
Why do you weigh less in the morning? The phenomenon of weighing less in the morning is a surprisingly common occurrence. Studies have shown that the average person will weigh, on average, 1-3 pounds less in the morning than they do at night. This lighter weight is often attributed to natural bodily processes such as respiration and perspiration, which can cause the body to lose water.
Other factors that contribute to this difference in weight include digestion and postural changes, as well as variations in the diet throughout the day. Ultimately, weighing less in the morning is a perfectly normal phenomenon, and it should not be a cause for concern unless there are other signs of illness or dramatic weight changes over the course of a few days or weeks.
