lose wieght?
A dieting person loses weight.
a closed system will not gain or lose mass
it loses mass! and actually it gains weight because of its mucles Actually you only gain weight with muscle mass if you exercise, therefore increasing the muscle mass.
If by space you are referring to volume, then NO. Matter doesn't lose a considerable amount of mass when it changes volume. See: Law of Conservation of Mass. However, if the volume increases and the mass does not the density of the object decreases. Summary: No. It doesn't lose mass. But it does lose density.
number 1. of course they can what do you think they are going to lose hair? err no number 2. nobody likes a smart ass. mass is only used in scientific measurments. when dieting and in the real world it's called weight
if anything it would be reasonable to expect it to lose mass.

I highly recommend reading up on the Atkins induction (week one) phase on Atkins.com. You can lose 10 lbs. in a week or two and not lose muscle mass.
No. Mass is directly propotional to weight.
Mass, being the total amount of matter in an object, would change when you run, because you sweat when you run. If you ran every day, you could lose a considerable amount of weight (mass x force of gravity), so you would also lose mass.That being said, mass is not = to weight, but YES, you can lose mass by running
