I drink a lot of water. Easily 4 liters pure liquid on normal days, 5+ when exercising (5 days a week).

I heard as a child, that salt and water are stored and produce compartments similar to fat.

Is that really true? Is there such a thing as water weight and could I reduce my body size, by cutting back my water intake to 2 liters of liquid a day?


Yes you can retain water, but since you are exercising 5+ days a week you need that water to help you hydrate and will not retain much of it at all.

When you exercise, you force the veins to carry back waste products and used-up blood to the heart, which, in turn, cleans that blood, with the aid of other organs. This aids in the secretion (much of it through the bladder) of excess fluids.

People who don’t exercise, on the other hand, often develop swollen limbs, over-burdened organs, and weight gain. Exercise is, in fact, one of your best defenses against water retention.

    That source seems more like a blog post then something authoritative. It doesn't link to research or any evidence. – Eric Nov 10 '14 at 6:15
  • It's a well-researched blog post, at any rate -- I certainly couldn't name six categories of drugs, nine diseases, or four nutritional deficiencies that lead to water retention. – Noumenon Jan 10 '15 at 15:08

Assuming you have sufficient sodium, your body will do a good job regulating your water level; if you drink too much, you will excrete it.

  • Could you elaborate or supply a link on the connection of sodium and water retention? Thanks for your answer. – Minix Nov 10 '14 at 7:57
