Bilal might have done it for the role else he always look fit even when he is not doing any dramas. He gained weight for pyaar ke sadkey as well then looked all bulked up in dunk. In KA and dobara he looked quite lean and fit.
Areeb is zaviyar, right? I guess that guy is naturally on the heavier side going by how Noman ijaz looks and he might be not into dieting and gym.
