we have a scale at work. If we put it on the carpet we weight 4 pounds more than when we put it on the tile. Thanks for all your answers. You're all very smart.

No difference. BUT.... you may feel a difference in the sensation of PRESSURE on your feet depends on what you are standing on. More cushy materials will spread out pressure from your weight across your feet better than harder surfaces, and you may feel less force pushing back per square inch from underneath giving you the subjective feeling of being lighter.

The mass and weight are independent of the surface on which you are standing on earth. The mass is same throughout the universe but the weight depends on the acceleration due to gravity. So, if you go to the top of a mountain, you will weigh a little less compared to a deep mine, since in the later case, you are closer to the centre of the earth and the force F between you and earth is given by
F = m.M/r^2 where m is your mass, M is the mass of the earth and r is the distance between the centre of gravity of you and the centre of the earth. So, smaller the r, higher the Force and Force = m.a where a is the acceleration. In this case, a is called g the acceleration due to gravity.

Since YOU posted this question, perhaps you know something that most of us do not. It never occurred to me that my weight could fluctuate depending on the type of flooring that I was standing on. I sincerely doubt it. If this a trick question, then: If you were to stand on a bathroom or physician's measuring scale with a 12" square of carpet under your feet, then you'd weigh your normal weight plus the nominal weight of carpet square. If you stood on a couple short planks of wood flooring under your feet, you'd weigh a bit more. And if you had a standard 12" ceramic tile under your feet, you'd weigh even more. How's that for reasoning? :)

Standing on a weighing machine, what applied is newtons third law. Every action has equal and opposite force. But laying it on a carpet will absorb some of your force, which results in showing lower weight than the actual.

No difference. While you are on Earth, the surface gravity doesn't change significantly, and that's only due to physical location, not surfaces. And your weight is determined by gravity.

Everyone is correct. If you have discovered some new magic on reducing weight on different surfaces, then it must be advertised as a new diet miracle to losing weight.

None. Weight (0n earth) is determined by your body mass, and the distance your are from the center of earth's gravity.
