Water in/water out?

I have a question about fluid intake and fluid expelled from the body. I currently have about a daily intake of 100 oz of fluids.  But there is no way that I am urinating anywhere near that amount.  I know that  some is lost through the skin pores and you exhale up to a quart of vapor per 24 hours and ofcoarse some of it is in the bowels, but where is the rest of it?   I have only lost 1# this last week and I am wondering if I am retaining/storing fluids. 

Papabear, Yep, you’ve accounted for where the water is going… It is hard to estimate how much exits the bowels.. 1 gallon of water equals approx. 8.3 lbs. and there’s about 10 lbs of water retention "wiggle room" in the typical body. (based on 20% body fat content) It has to do with Glycogen stores in the muscles as well as the fat tissue. Each lb. of stored glycogen takes approx. a quart of water (or roughly 2 lbs of water) To utilize the stored glycogen. So the muscles alone CAN hold on to around 10 extra lbs Even when a person has lower body fat percentage over all. Get a little exercise and the glycogen is used up along with that excess water. Get a little rest, and the liver takes fats and processes them into more stored glycogen. Get a lot of "rest" and the body takes excess calories and (If the glycogen stores are full,) the extra calories store in excess fat tissue. Water retention for guys with body fat of 25% or higher Can be roughly the same as women ‘retaining’ water during a menstrual cycle. Sodium levels can also come into play. Some natural diuretics include- Celery, Parsley, Asparagus, Melon, etc… Also, higher glycemic foods such as sugars and simple starches (White Carbs- flour, rice, pasta, potatoes) can also coax the metabolism To hang on to excess fluid. As glycogen stores are depleted and the body utilizes water to replenish them Water gets stored in the body as well. There is typically about a 3 to 4 week Supply on hand prior to surgery, So Many folks experience a slow down or stall in weight loss Around the 4 week mark out from surgery. I’d put a bet on it that in a few weeks you’ll be back to losing at your previous rate. Check you calorie intake versus calorie expenditure on some tracking method like fitday.com, And know that you can easily have a 10 pound increase due to water retention, Even While showing a Calorie deficit by the numbers. Best Wishes- Dx

Good post, Dx

Don't forget that cellular respiration utilizes water in the creation of adensoine triphosphate (ATP...the actual energy used by muscles). In other words, your body busts up water to create energy.

I also experienced my first plateu at that 3-4 week market. I had thought it was because I resumed eating actural food and that my metabolism had to get readjusted, but Dx, your explanation makes a lot of sense. I remember that first plateu being the longest one I have had yet - three weeks! Hope yours busts soon!
