The Home and Away actress, who plays Charlie Buckton in the Australian soap, said that she lost a lot of weight after taking part in Dancing with the Stars Australia last year and then struggled to put it back on.
When asked if she thought she was too thin at the time, Anderson told New Idea magazine: "Absolutely. I was eating as much as I could but that's just the way my body is. I don't exercise a lot, so when you add 30 hours of training in, my body changed. But it's history now and I feel really good and womanly again.
"I just wanted to get back to my normal size as quickly as possible. I'm back to my normal weight. I eat whatever I want, but it's healthy."
Anderson continued: "I was brought up on healthy food. I don't exclude anything - I have treats. It's just not too much excess. I love coffee and I love wine. I eat pizza.
"It's been a huge year, in terms of my professional workload. I'm so content with my job and where I am in life at the moment. Everything feels as it should be."
After her dramatic weight loss on Dancing with the Stars, Anderson said: "I don't want young girls to look at me and think I'm trying to be skinny and that I think protruding ribs look good, because I don't. I would love to be a lot more curvy."
She also said that all the hours of dancing made her feel hungry.
