At home on a set of scales i weigh 12 stone, and live 120 feet above sea level. if was to move to the top of a hight mountain, say 2000 feet above sea level would i weight less, more or the same?

I think you would weigh less due to the fact that there's less air pressure pushing down on you.

Your weight would probably be reduced to say the weight of a BK Whopper with fries !  []

The lack of said items, could also be a reason why i may lose weight

I believe neil is right. you will weigh ever so slightly less then before at a lower altitude. I think someone explained that to me when discussing gravity at one point!

Au contraire, reduced air pressure would also mean reduced air density, and so reduced buoyancy effect from the air, so that alone would cause an increase in weight (just as, in more extreme cases, you weight less at the bottom of the sea than you do at the top of the sea, because of the greater density of water at the bottom of the sea).

What would happen is that as you get further away from the Earth, you will have a very slightly diminishing effect of gravity (but that will probably be even more imperceptible than the changes due to air pressure).

If you want to lose weight quickly, probably better off heading for the equator, since the additional centrefugal force of the Earth spinning will do more to offset your weight (not that even that would be very significant).

Sorry ...did I say ' lose ' weight.....?..I meant gain weight of course !!...tch ..these transposition errors sneak in all over the place !!  []

Hey I really thought you gained a little at lower so I was wrong too!!
