Rebel Wilson says she ate more than 12,500 kilojoules a day before her health overhaul

Rebel Wilson has been kicking goals throughout 2020, and she's now reflecting on how far she's come.

Wilson, who recently shared she's dropped 40 lbs (18kg), dubbed this year as her "year of health."

The How To Be Single actress credits a high-protein diet for her weight loss success after she became accustomed to eating "3000 calories (approx. 12,500 kilojoules) most days."

"Because they were normally carbs, I would still be hungry," Wilson exclusively told People. "So, I've really changed to eating a high-protein diet, which is challenging because I didn't use to eat a lot of meat. I eat fish, salmon, and chicken breast."

Despite the diet overhaul, Wilson admits that not every day is perfect.

"It doesn't mean every week is a healthy week," she said. "Some weeks are just write-offs, and there's nothing you can do about that.

"I'm just trying to go for overall balance, overall healthy balance. I have this state of being, which is not my quote, but I go 'Nothing is forbidden.' We'll be like, 'Should we get In-N-Out burger?' And I'm like, 'Nothing is forbidden.' I can go there, I just might eat half of what I used to eat before. You know? And I'll have a burger, and a few fries, and then you feel fine."

The Pitch Perfect star also discussed how the pandemic gave her time away from work to abolish bad habits.

"I definitely think with the slow down, it did help," she said. "I think I was emotional eating, and overeating at times because I wasn't loving myself enough either. And it does come down to that self-worth and self-love."
