Rebel Wilson's "healthy habits" are important for her mental health.

The 45-year-old actress embarked on a weight-loss challenge around Easter, and Rebel has now offered some health advice to her social media followers.

The 'Bridesmaids' star said on Instagram: "Ok, so you delete some things from your life that are unhealthy and pick up some healthy habits.

"So not just focusing on but trying multiple healthy habits, which will be a struggle.

"I might have to write myself a little checklist on a post it note and make sure I'm trying to do each thing each day.

"But I tell you what, if you can get into a really good groove with all these healthy habits, it can be really great for your physical and mental health and that's really important."

Rebel subsequently encouraged her followers to update her on their progress.

She added: "I just want you guys to be the healthiest versions of you that you can be.

"Congrats to everyone that's been on the challenge. Let's go hard week six. Let's do it."

In 2023, Rebel claimed that her 'Pitch Perfect' contract prevented her from losing weight.

The actress played Fat Amy in the hit film franchise between 2012 and 2017, and Rebel revealed that her contract stopped her from shedding weight.

During an appearance on the 'Call Her Daddy' podcast, Rebel explained: "I couldn't lose a massive amount of weight, because I was in the contracts for that movie.

"I think it's not more than ten pounds [you can lose] and not gain more than ten pounds. You have to kind of stay at the weight that's in your contract."

Rebel embarked on a so-called year of health in 2020, as she made a determined effort to lose weight.

However, the Hollywood star had been thinking about adopting a healthier lifestyle for years.

Rebel - who ultimately managed to lose 60 pounds through her health journey - said: "I was stereotyped in playing that fat, funny friend. I love doing those roles, I love those characters, but then I did want to do more things. But then I felt like being the bigger girl, you're just more pigeonholed."
