The weight lost from perspiration and the passengers burning calories
is insignificant. Consider that a plane burns a few thousand pounds of
fuel per hour, then even if you had each person managing to burn a
pound of energy sustaining themselves on the flight (a generous
guesstimate) on a 747 you'd come in ~400 lbs less at landing than
takeoff. No biggie.


And that would assume the pound used to sustain themselves left the
plane. After all, if you lose a pound, it doesn't disappear, it goes
someplace.


I'm not talking about people ****ting here. When you sit at your
computer, your body burns calories generating heat, speaking, moving
around, digesting food, etc. The mass of food you ate on the plane or
before boarding is converted to heat, sound, kinetic energy. The fact
that people sit on a plane more or less emphasizes that this loss of
energy, and the mass used to create it, is tiny, and therefore

negligible.


This is not a nuclear reaction, the energy is created by the breakdown

of
chemical bonds in the food. No mass is lost at all.



Are you saying, that when you excercise on a daily basis to lose weight,
that any weight you shed must come off in sweat and waste only?


You are 'burning off fat' Fat is only stored energy, and this is broken down
into something you ****/****/sweat.
