"I didn't know I was depressed," the actress tells Dr. Oz on his talk show in an interview airing Friday. "I mean, I knew it was a sad moment in my life, but I wouldn't categorize myself as depressed. I'm not that, I'm an optimist about life. Life didn't work, moving on. I'm fine."
Meanwhile, the people around Longoria, 38, were telling her how well she looked. "That's probably the time I got the most compliments because I was so skinny. I was not eating. I was depressed. I was sad. My diet was coffee. So people kept saying, 'You look amazing. Divorce agrees with you,' " she says. "And I was like, I don't feel good. I have no energy."
It wasn't until a doctor's visit that she realized her depression was hurting her health. "It was like all these things were physically wrong with my body, so I had to saturate with vitamins and kind of get back on this track," she says.
Part of getting back on track, she tells Dr. Oz, was cutting sugar completely out of her diet.
"For about three months, I did a really strict no-sugar diet, and I had more energy than I've ever had," she says. "My palate was different. Things tasted better."
