So what you're saying is if I move to a higher elevation I can loose 3% of my body/mass index??
Wrt “body/mass”, it wouldn’t make a difference … mass is independent of the gravitational field. It is weight that depends on the gravitational field.
If you were to determine something’s mass, you would use a BALANCE. The mass of your sample would be the same between the Earth, the Moon or Mars.
If you were to determine something’s weight, you would use a SCALE. The mass of your sample would be different between the Earth, the Moon or Mars.
If you are not having success with your diet and training and you are interested in losing weight, I would suggest possibly colonizing the moon. If you are interested in changing your body/mass index I would suggest liposuction.
