The Scissor Sisters singer shed 28lbs in 2010 and although she is thrilled with her new look, she isn`t a huge fan of exercising.
She said: "You just have to make yourself do it. And once you have, you`re always so happy you did! Now I try to remember the feeling I have when I leave the gym, rather than the dread before!" Although Ana doesn`t love exercising, she does try to do some physical activity every day in order to maintain her new shape.
She added to new! magazine: "When anyone changes appearance, people want to know why and how you did it. I hit my mid-thirties and thought, `Oh, this isn`t good, I`d better get to the gym.` For me, it wasn`t so much about losing weight, but getting healthy. To do this, there`s been a shift of my whole consciousness and it`s now part of my life and something I have to do - if not every day, then every other day!"
"I gave away all of my old trousers and that was a good feeling."
