The negative Gs from an abrupt level off come from the fuselage attempting to continue upward while the control force input makes the airplane change direction, hence the force going up changed to downward. The wing and aircraft structure "force" the airplane down into a level flight or below that from a climb, which causes the reverse Gs, or repelling feeling, like being momentarily weightless, which is the negative Gs. However, the force is applied to the wing and fuselage where the wing is attempting to stop the fuselage from continuing upward so the wing creates a downward force, while fuselage tries to continue upward, attempting to bend the wing down away from the pilot. The inside loop positive Gs are keeping the loop going by creating more lift, while the fuselage wants to keep going straight, positive Gs even though we go inverted through part of the maneuver.
