Actress Rani Mukherjee has always had weight problems. She keeps alternating between looking fabulous and flabby, depending on her work schedule. But for her upcoming film to be directed by Kunal Kohli, the actress will be seen at her toned best.

In Kohli's next, starring Saif Ali Khan and Rani, the actress is required to sport a lean look. According to sources close to the actress, Rani tends to put on weight very easily. She has a craving for sweets and loves to gorge on them. But in the past few months, she has been very careful about what she is eating and has also been following a rigorous workout schedule as well. Apparently Rani was not very happy with the way she looked in the second half of Laaga Chunri Main Daag. She wants to loose more weight and has been asking friends about the most effective diet plan or routine to follow. Kohli's yet untitled movie is based on the popular classic Mary Poppins and will have Rani wearing a figure hugging costume fitted with wings. Though Kohli does not think that any actress has to loose weight to give a good performance. He says that he has never asked any of his actresses to loose weight. For him, the best shape an actress can be in, is when she totally fits her character.
