Emma Stone Reveals Her Biggest Weight Struggle

May 6, 2014 -- Emma Stone is getting used to walking the red carpet, but she's not accustomed to the criticism that often comes with it.

The "Amazing Spider-Man 2" actress said that she's naturally thin, and it's tough to read comments about her body that insinuate that she doesn't look good.

"Keeping weight on is a struggle — especially when I'm under stress, and especially as I've gotten older," she told Cosmopolitan. "That's the way my genes have decided to go, and things will change as time goes on, as does everything."

Emma Stone Calls Andrew Garfield 'Incredibly Important Person to Me'

Stone, 25, who recently showed her feminist side by challenging real-life boyfriend Andrew Garfield about the definition of "feminine," opened up about reading "completely untrue" statements about her and her health. Her main goal, she said, is always to be honest with herself, asking herself questions like, "Am I respecting myself and being responsible?"

"Over and over, I answer yes to that question," she said. "Then I remind myself to be kind to myself, and as slightly ridiculous as it may sound, to treat myself in the same gentle way I'd want to treat a daughter of mine. It really helps."

"I'm actively working hard on learning to appreciate yourself no matter what," she continued. "If what someone else says can easily derail you, it means your sense of self isn't that firmly established in the first place. It's an inside job. You're beautiful and worthy and totally unique. People insult each other based on their own insecurities — even though it may feel personal, it really never is. Really. Seriously."
