How Do You Lose Weight While You Sleep?
Posted on June 27, 2013 Comments (1)
In this interesting webcast, Derek Muller, (a physics teacher in Perth, Australia) explores how much weight you lose while you sleep. As physics teacher he asks the sensible question: how do you lose weight while you sleep, what weight do you lose?
His conclusion is you lose weight through perspiration, water vapor in your breath and expelling carbon dioxide. Losing the water weight is pretty straight forward. The process of adding carbon to the breath we expel is not something I thought of. He calculates that we lose about 100 grams of carbon during a night of sleep. In his somewhat scientific experiment (measuring himself for several days) he lost about 150 more grams, which he attributes to water vapor and perspiration.
It seems to me the amount of carbon we lose during sleep is probably much more consistent than the amount of water weight we lose (both between people and variation between different days).

If you burn 500 more calories than you eat every day for a week, you should lose about 1-2 pounds.
If you want to lose weight faster, you’ll need to eat less and exercise more.
For instance, if you take in 1,050 to 1,200 calories a day, and exercise for one hour per day, you could lose 3-5 pounds in the first week, or more if you weigh more than 250 pounds. It’s very important not to cut calories any further — that’s dangerous.
