If the rotation of earth increases, the weight of body decreases.
Then why the gravity or weight on Neptune is less?

@Akshay.
How can you add or subtract the centrifugal force from gravity? Please check the dimensions of both.

The centripetal force also acts there towards the center. Why does the weight not increased?

It's true I think it follows the newtons third law.

With rotational speed centrifugal force on us outward increases, decreasing the force on us due to gravity.

If the rotating speed of earth increase then our body weight will be decrease because by the acceleration of speed centrifugal force will produce which will reduce the gravity force.

If spinning speed of earth decreased than weight of the body at poles does not change why?

@Akshay.
Its centripetal force not centrifugal that makes a body to follow circular path.

g' = g-w^2rcos^theta.
w = Angular velocity if w increases g' decreases.
w = Angular velocity if w increases g' decreases.
