R&B star Kelly Rowland says she will never be size zero and only hits the gym to stay healthy. The former Destiny’s Child singer works out as often as possible but insists she doesn’t worry about how many pounds she drops, Femalefirst reported. “It’s not all about dress size but also about being healthy as well. I’ll never be a size zero. I’m happy being a size 10, but I want to be healthy. I work out every other day at least. If you don’t then I don’t think you see the rewards. Even if you can get 30 minutes of cardio in every other day you’ll see a big change in yourself,” she said. Rowland, 30, follows a healthy eating plan, but doesn’t believe in depriving herself of her favourite foods. “There’s a great diet called the 80/20 diet, which means you make sure 80 per cent of the stuff you eat is good and the other 20 per cent is your choice. It’s great because it means you’re not depriving yourself of anything.”
