Want to lose weight quickly?
Your weight is the result of two forces, one pulling you down and one flinging you up. At the exact North Pole there is no rotation, so the flinging force is zero. The rotation at the equator is at its maximum. Therefore you will weigh less at the equator than at the North Pole! Fast diet.
A 200 pound person will weigh 2.5 ounces less at the equator.
