unless you loose wight, it stay's the same on Earth. Weight is differant on the moon...but mass is the same. Mass is related to weight. If you loose weight, you loose mass.

Oh, man, the answers are all over the place on this one, aren't they? Let's sort out a few things, if possible.
First of all, mass is constant and independent of gravity (assuming that you haven't just consumed a Quarter Pounder with Cheese, that is).
If you know your mass, you can easily find your weight:
W = mg ...where:
W is weight in Newtons (N),
m is mass in kg, and
g is the acceleration of gravity in m/s^2.
If your mass is 70 kg, your weight on Earth (at sea level) is
W=(70 kg)*(9.8 m/s^2) = 686 N.
Chill out, one Newton equals only about .225 pounds.
Getting back to your question (remember your question?), even though your (Big Mac-independent) MASS is constant throughout the universe, does your WEIGHT also remain constant around the Earth? The answer, alluded to in various ways by your faithful answerers, is NO! But where, and why?
High altitudes can carry you further from the center of gravity of the Earth, potentially helping you lose weight. This is true because g (the gravitational force) is not contstant, but drops off as the square of the distance from the center of gravity.
How about if you're standing really close to something dense? (That happened to me at a party recently, and it was pretty heavy, too.) Yup, you may get heavier, because the "bump" in gravity from that heavy thing might add to the total gravitational pull.
Are these (altitudinal or dense-object) effects significant? Not very. They are probably quite small compared to the natural fluctuatons in your body weight throughout the day.

no, but your mass does. Weight = mass times the force of gravity. The force of gravity varies inversely with the distance from the center of the earth. Therefore your weight on the top of Mt. Everest would be slightly less than at sea level

Unfortunately the answer is yes, as long as your on the earth your weight remains the same. Good thought though, to lose a few pounds just travel to another part of the globe, but not that easy.

Since the strength of the gravitational field fluctuates on the Earth's surface, so would your weight.

Actually, you can notice a change in your weight at very high altitudes. You are able to jump somewhat higher. Also, in a dropping elevator you weigh nothing for a second.

your weight will change depending on your distance from the center of the earth but the change won't be noticable until you become an astronaut.

No. Minute differences will occur as you move up/down in altitude. Also, your weight will fluctuate as you move from place to place (burning calories, eating, etc.).

no. Tough the change is insignificant it can be noted.
The closer you get to the center of gravity of any mass the more you are "pulled" (the more you weight).
