Drinking more water is a common strategy used to promote weight loss.
However, while many people believe the weight loss may be due to increased urination, others claim this is little more than a myth.
This article takes an in-depth look at the evidence to determine whether you lose weight when you urinate.
The urinary tract is responsible for removing excess fluid and waste from the body.
It comprises several organs, including the kidneys, bladder, urethra, and ureters.
The kidneys are responsible for filtering blood to produce urine, which is transported to the bladder by thin tubes of muscle known as ureters.
The bladder is a hollow organ that slowly expands as it fills with urine. It’s estimated that the bladder can hold up to 2 cups (475 mL) of urine.
As your bladder starts to fill up, it sends a signal to your brain indicating that it’s time to urinate.
Finally, urine is excreted from the body through the urethra by relaxing the internal and external sphincters, which are muscles that control the flow of urine (1).
On average, most people excrete around 27–68 ounces (800–2,000 mL) of urine per day (2).

Urination plays a key role in fat metabolism.
This is because when you consume fewer calories than your body needs, fat stores throughout the body are broken down and used for energy.
The byproducts of this process are then excreted from the body through urine, sweat, feces, and the lungs (3).
Urination may also cause other minor changes in body weight.
For example, when you drink a large amount of water, you may notice that the number on the scale increases slightly. Contrarily, when you urinate, it decreases slightly.
These fluctuations are normal, as studies show that increasing your daily intake …….
