Sonam Kapoor : This sultry fashionista with her dazzling smile and enviable height, too, had to fight some flab before she joined the Bollywood bandwagon. As a teenager, Sonam Kapoor used to weigh around 90 kgs. But when she was offered a role in Saawariya, she underwent rigorous weight reduction workouts and lost nearly 28 kgs! With time, she even lost those grandma arms which we saw in Saawariya, and today, she undoubtedly has one of the best bodies in B-town!
Sonakshi Sinha : Daughter of popular actor Shatrughan Sinha, Sonakshi lost nearly 30 kgs before she stepped into Bollywood. But what we love the most about her is that, instead of working hard to achieve a stick-thin figure like her contemporaries, she just shed off the unhealthy flab and kept her curves!
Kareena Kapoor : Her ravishing size-zero figure in Tashan as well as her curves in Ra.One had one thing in common: Both had women dieting, exercising and craving to look as hot as her! But well, she hasn’t had it easy either. As a teen, Kareena was really chubby. But even with her plump cheeks and pudgy arms, we think she looked really adorable! (Source)
