1) Please learn to trim quotes
2) Have you somehow forgotten the laws of thermodynamics? It is quite
simple: if energy in energy out, the body will gain mass. If
energy out energy in, the body will lose mass.



Let's say that eating fiber caries a certain amount of calories through
your body so that you don't digest them. Then, while calories in might
not change, eating more fiber would change the amount of calories out.

These "laws" are based on ideal situations. For instance, "an object in
motion tends to stay in motion" works great IN A VACUUM. It doesn't work
nearly as well in atmosphere.

People aren't closed systems. While these "laws" can help to describe
what happens to people, they aren't 100% accurate.
