Soul star Chaka Khan dropped 60 pounds (27.2 kilograms) in a year thanks to extreme dieting and fasting.
The I'm Every Woman singer showed off her slimmed-down new look during a performance on the American Idol finale on Wednesday night (23May12) and confesses it wasn't easy losing all that weight.
She tells U.S. news show Access Hollywood, "I started out fasting... for four months. I did nothing but liquids; me and my VitaMix were best friends.
"In the morning I'd have a high protein smoothie and in the afternoon I'd have a vegetable smoothie and in the evening I'd have another protein smoothie."
