Alia Bhatt: Bollywood’s favourite bubbly star Alia Bhatt was once asked by Karan Johar himself to shed 20 kilos if she wanted a role in his film. And the actress exactly that, and shed 16 kilos in a span of 3 months just through rigorous work out and sheer determination. Running on the treadmill, dumbbell raises, push-ups, lateral pull-down, bicep curls were just some of the things Alia did to shed her weight.
