Ana Ivanovic tells AFP that she does not have a weight problem and has not been dieting.

"I don’t feel that I've seriously lost weight," No. 12 Ivanovic said. "This year I've been working really hard and I was travelling a lot. I experienced some stressful situations and sometimes lacked quality food during my travels. But I believe that when I get home at the end of the season, I'll feel myself more relaxed and will gain some more weight. I have enough energy but I think I shall become more stronger anyway because I play aggressive tennis and need to get that heaviness of the shot.”
