Diaz has apparently struck a deal with publishing house HarperCollins to release a health and wellness book late next year.
The star has a body issue that many of us would love - she finds it hard to put weight on. She also loves sport – running, surfing and in recent years resistance training, which accounts for her more muscular figure of late.
She has said, ‘I'm consistent, and when I'm not consistent, it shows up on my body.’
‘I get really skinny, and I know it might sound like, 'Well, good for you'. But the body that people talk about is not me trying to stay slim, it's the one where I work hard to keep weight on me. Your body definitely does change.’
