Ram Charan to have Rambo inspired body in 'Vinaya...'
Being helmed by Boyapati Srinu, the film also stars actress Kiara Advani in the lead role.
Ram said it was "the commitment to the director's vision and the thought of the final output" that kept pushing him.
"It is extremely easy to get distracted when you are on a diet. Luckily for me, Upasana (my wife) is really good at whipping up some extremely tasty healthy food," he added.
"Vinaya Vidheya Rama" is scheduled to release on January 11. It also features actors Vivek Oberoi, Prashanth, Naveen Chandra, Sneha and Aryan Rajesh in pivotal roles.
