have heard this a few times from various people that an indicator you are losing weight is that you keep needing to pee. Anyone else heard this?

If you drink a lot of water and have excess sodium in your system, then you will need to pee a lot.

The only weight you are losing though is water weight.. and that can easily be gained back depending on what you eat, water levels, etc.

I have to pee a lot anyways. Drinking more water has not changed that, which is a little scary. But yeah, the above poster had it right - it flushes out water weight. It's not the act of peeing or anything that makes you lose the weight.

I feel like I'm visiting the restroom a lot but I know it's because I drink a gallon of water a day. I think most people who take up a healthier lifestyle tend to consume more liquids.

If you're not drinking much and need to pee a lot, this can be a sign of diabetes.

depends on your water intake.

I know I started peeing a lot after I stared working out a lot. Probably both to do with flushing toxins out of your system and the fact that I drink a lot. I drink on average probably 3 liters of water a day, so yeah, a lot of times I'm going every hour. Kind of a pain sometimes.

Well, the peeing isn't making me lose weight but I keep trekking up the stairs to get to the bathroom laugh Honestly, I've always had a small bladder, but now that I've started drinking more water I'm ALWAYS going!

Concretegirl is right: Correlation does not equal causation. Just because two things are related doesn't mean that one caused the other. However if you are upping your water intake then you'll pee more!

It's the fat and toxins flushing out. Or you drink more water and eat more water-dense foods like fruits and vegetables. It's definitely either one or the other.

There are several things besides muscle that make up the weight you see on the scale. Extra water in your system, Food in your intestines, fat in your body. When you drink extra water, your body gets rid of the water it does not need, when you have a bowel movement you get rid of food left in your intestine, when you cut calories and exercise you can lose fat, you need to cut 3500 calories to lose a lb. All will lower the number on the scale but cutting the calories and exercise will keep it off.

When I cut out sodas and switched to water .. well .. yeah .. I felt like I was pregnant all over again and running to the bathroom every 5 minutes! LOL

As I increased my water intake, so did the need to pee .. however .. that has balanced itself out again and even with my increased water intake -- I'm back to peeing normally again (whew) I was starting to think I needed to give up water .. laugh

I drink caffeine and alcohol as well .. .that doesn't seem to affect my need to go as much as when I started drinking more water.

Your body will adjust .. you tend to lose water weight early on and if you're changing your diet to be healthier, incorporating more water and clean eating. After a couple of weeks, your body will go back to a normal routine that is more desirable than running for the loo every few minutes wink

This is part of the fat burning metabolism - "To remove the fat to use as energy, the body empties the fat cell. Technically, the "fat" in the cells are triglycerides. Once removed, enzymes break down the triglycerides into two components, glycerol and fatty acids. The liver, kidneys and muscles absorb the glycerol and fatty acids to produce energy and heat. Waste products from the breakdown are excreted by the body through urine, expiration and sweat. The usable portion of fat is transferred to energy and the unusable portion leaves the body as waste." from

I don't see the argument that fat burning cause more urine.

I am inclined to say it is related to the water intake. By drinking more water you will excrete more water and that is one good reason for a higher urine output - and by living healthier (i.e. avoiding processed food) you get less sodium to bind water so you are getting rid of excess water. Thus your urine output increase because the water bound to sodium is released. After a while you will have 'homeostasis' of water - and you won't pee quite as much.

It's nothing to do with fat loss or toxins, there is no science backing those claims AFAIK. Might be to do with you drinking more fluids/ eating more fluids in the form of fruit and veggies, might be eating fewer carbs (1g muscle fuel glycogen held alongside 3g water), could be burning more carbs through exercise and depleting the muscles of glycogen, could be eating less processed sodium rich foods or most likely a combination.

I found this article interesting, you do pee more because of the extra waste your body needs to flush out.
