Mustafa, son of director Abbas, says for him the most challenging task was to lose around 70 kgs for his debut film "Machine".

"I was 120 kgs and would eat anything and everything because I was and I am still a foodie," Mustafa said in a statement here.

The newcomer had a personal trainer who helped him shed the excess weight gradually.

"It took me five years to lose around 70 kilos and achieve my current weight of 55 kgs. The first week of dieting was the most difficult. I also started working out and did everything from functional to weight training. I also used to run," he said.

A romantic thriller, "Machine" also stars Kiara Advani.
