How much a man weighs depends on the gravitational force with which you are attracted. The gravitational force on moon is 1/6 times the gravitational force on earth. Since the gravitational force is less, the man feels lighter on moon.

A person feels lighter or heavier based on the normal reaction force exerted by the floor he/she stands on. The weight of the person is the force the person exerts on the floor. This force is due to the gravitational attraction force (Newtons' law).
force = G M m / R²
G = Universal Gravitational constant, M mass of planet (Earth or Moon)
R = Radius of planet. m = mass of the person.
the ratio M / R² is more on Earth than on Moon. It is around 6 times.. So a person weighs less on the Moon. The mass of the person is the same on both planets.
