Zoe Saldana has banished the word 'diet' from her life.

The 'Guardians of the Galaxy' star, who gave birth to twin boys Cy and Bowie with husband Marco Perego in November, is trying to focus on improving her health but admits she struggles to avoid junk food at the weekends.

Writing on her official Facebook page, the 36-year-old actress said: ''By Friday I'm anxious about what I will have to do over the weekend to avoid breaking my diet. I find myself dreading the awesome family feast gatherings, friends inviting me over for a 'wine and dine' on Saturdays, and then of course Sunday brunch. WTF!!!

''So here is what I'm gonna start doing; I am going to remove the word 'diet' from my life. I am going to remind myself that it is not about losing weight, it is about being healthy, feeling healthy, for the rest of my life (sic).''

Zoe is eager to regain her pre-pregnancy figure in a healthy way, but previously admitted her body ''was really bent out of shape after the boys were born.''

The 'Star Trek' beauty has taken to sharing her fitness and healthy eating tips with her fans via social media in recent months in a bid to inspire them.

But she added: ''I don't want to sound preachy or like I have it all figured out. I'm trying what's best for me and sharing it with you in hopes that it may inspire you to seek the same for yourself!''
