How much weight do you lose after urinating?
The average 24-hour urine loss is about 1.8-4.4 pounds because water is heavy. By contrast, it's virtually impossible to burn off a pound of fat in a day.
A person will get a less accurate measurement of progress if they use the scale at different times on different days. One of the best times for people to weigh themselves is in the morning, following urination. The reasons for this include: exercise or other physical activity will not affect the number.
Our morning void is usually the biggest, Meagan says, because our bodies have been making urine all night. “A normal pee first thing in the morning should be somewhere in the realm of 1-2 cups or 8-16 ounces. Healthy daytime voids are around 6-10 ounces each.”
Urine is more dense than water because it is composed of water and various solutes of different densities. Therefore, urine always has a specific gravity greater than 1.000.
While peeing more frequently is unlikely to lead to weight loss, increasing your intake of water may support your weight loss goals. In fact, some research shows that drinking more water could temporarily boost your metabolism and reduce your appetite.
Your body must dispose of fat deposits through a series of complicated metabolic pathways. The byproducts of fat metabolism leave your body: As water, through your skin (when you sweat) and your kidneys (when you urinate).
Urination lets the body get rid of excess water and sodium. Water pills are not recommended for long-term use. They should always be used as instructed by a doctor to avoid dehydration or mineral deficits.
Keith Kantor, a leading nutritionist and CEO of the Nutritional Addiction Mitigation Eating and Drinking (NAMED) program. “After a swim or a shower, your body can absorb 1 to 3 cups of water, increasing your true weight by a few pounds.”
Yes—for obvious reasons! But for those of you who aren't squeamish, we'll explain. When you have a bowel movement, you're emptying your colon. Depending how much you go, that visit to the ladies' room can add up to half a pound a day—hence the reason you feel so much lighter after you poop.
An excessive volume of urination for an adult is more than 2.5 liters (about 67 fluid ounces or about 2.6 quarts) of urine per day.
Do you lose ounces when you pee?
After urinating, you may notice you've lost at least a few ounces of water weight if you hop onto the scale right afterward. If we define “losing weight” as the metabolism of body tissue, however, no, peeing does not make you lose weight.
A healthy bladder can hold about 2 cups of urine before it's considered full. It takes your body 9 to 10 hours to produce 2 cups of urine. That's about as long as you can wait and still be in the safe zone without the possibility of damaging your organs.

Fat burning can make you pee more because when the body breaks down fat cells for energy, one of the byproducts of this process is water which you pee or sweat out of the body [1]. One of the ways to boost fat metabolism is by decreasing your food intake through dietary changes.
Research shows that 84% of fat loss is exhaled as carbon dioxide. The remaining 16% of fat is excreted as water. During the conversion of energy, carbon dioxide, and water are byproducts of waste. They are excreted via urine, perspiration, and exhalation.
