Where does it go?

Seriously, I have read some other posts and articles, but for me this remains as one of the biggest misteries in life.

I've been gaining and losing weight during my entire adult life, but it wasn´t until I got a digital scale and started to weight myself more frequently, that I realized how much our weight fluctuates.

Seriously again, how is it that we can gain/lose 2 pounds of weight overnight, do we actually spread 2 pounds of fat in our bed, or does 1 litter of water just evaporates or is absorbed overnight?.

You will often oxidize some body fat while you're sleeping, but not much. How much depends on a lot of factors, but for most of us, it will be far less than 2 pounds. More like .1 or .2 pounds. The rest of it will be water.

Respiration and transpiration account for it. When you breathe out, you lose water - breathe on a mirror to see. You also lose water through your skin (transpiration). The more you sweat, the more you lose.

Supposedly, we lose about a liter of water a day through our mouth and skin - over 2 pounds. If you're active, it's probably much higher than that.

Fat leaves the body through sweat, urine, and well, poop. Sometimes we retain water, or maybe sometimes we just dont quite burn off all the carb and calorie energy from the day before. Sometimes when we exercise strenuously it will cause significant weight gain for a couple of days because when we work our muscles strenuously, they will retain water while they repair themselves. A good idea when your weight fluctuates is to record all your weighing for 7 days, add them all together and divide by 7 to get an average weight for that week.

Not quite true. Fat is made mostly of Carbon and hydrogen. Very little of it leaves in these forms. Your body is an engine that burns fuel (carbohydrates) with Oxygen. The exhaust product is a recombination of these products into H2O, and CO2, which is exhaled mostly through the lungs. This is why aerobic exercise helps weight loss.

This is why it is best to weigh yourself only 1x a week at about the same time of day with the same clothes etc.. Water, poop, pee what you ate the night before, carbs, sugars, exercise, period etc. These are all factors in fluctuating weight. Weigh yourself every Fri (or whatever) in the AM after you potty but before you eat. And see if you find a more steady pattern that way.

Like hofraz said...if you insist on weighing everyday, average it out. But then you need to average out the feelings that come along with the number rising one day and loosing the next. If your numbers move that much you may want to decide if the feelings you get from going up/down are helping or hurting your weight loss and then change your weigh ins accordingly!

Lastly read this article, it just says everything that we all wrote to you, but may say it a little better! Good luck!
