When the elevator is accelerating upwards it has an acceleration.
According to Newtons laws of motion we have ,
R-mg=ma, where R and a are the upward reaction force and a is the acceleration .
Then R=m(g+a).
It is clear that, a'=g+a where a' is the new acceleration.
He will have a resultant force upwards due to which he will fill weightlessness.
