How does the body lose weight?

[antlers]

In addition to CO2, respiration gives up a lot of H20. Lots of the water weight we lose goes that way.

Elementally, our bodies are composed of hydrogen, oxygen, carbon and less important amounts of nitrogen, sodium, phosphorous, calcium, etc.

We shed carbon, hydrogen and oxygen through respiration. We lose hydrogen, oxygen, nitrogen and the less significant elements through sweating and peeing. We lose weight when these losses are greater than the elements we absorb from the food we eat.

I guess it is like how a car loses the mass of the gas in the gas tank. Combustion turns the gas into Co2, Water, and other by-products, those are then "exhaled" through the muffler.

How does the body stay at 98.6 degrees F?

Law of Conservation of Mass + Law of Conservation of Energy = Law of Conservation of Mass-Energy

American society is very open about sex, still about 30% of Americans are overweight....

Wow!!! I thought it was closer to 66%...

Don't forget epithelial tissue, and hair, that stuff's shed 24/7 too.
