Popular US talk show host Oprah Winfrey has vowed to battle her recent weight gain, saying "It's about using food - abusing food".
Winfrey, 54, who was recently admitted to a hospital after she weighed more than 90 kilograms, wrote on her official website that it was not about food and dieting.
"It's about using food - abusing food. Too much work, not enough play. Not enough time to come down. Not enough time to really relax," she wrote on her official website.
Winfrey, who was diagnosed with hypothyroidism, a hormonal imbalance triggering weight problems, said she was now "hungry for a balance," adding that she wanted to do something else than work and take more time for her well-being.
