In an interview with Reuters, Hudson revealed that she is more concerned with presenting a positive public image now that she has slimmed down.
"It's almost like there is a new person, but there is still the question of how do I want to represent myself, how do I want to be perceived," she said.
The Oscar winner went on to say that she has learned that changing one's diet is key to living a more healthy lifestyle.
She added: "It's one thing to lose weight, but it's another thing to eat healthy."
It was previously reported that Hudson is to perform on ABC's Dick Clark's New Year's Rockin' Eve With Ryan Seacrest 2011 telecast.
