as i know
1. total quad weight = 2 x total thrust produced by motors.
It will make your quad to do some arobatic stunts,flips etc.
2. total quad weight = 1.5 x total thrust produced by motors.
It will make your quad to hover and normal flight.
EDIT:
You will have two options
1. Reduce total weight of quad by using light material without losing its strength.
2. Increase more thrust by motor and prop combination.low kV motors and big props having more pitch give more thrust to quad.

@coolpratheesh
can't say about other ways mate, experts can have better answer but battery also plays important role. With same motor prop combination 2S and 3S lipos generate different thrust values.
