Now, she's revealed what made her take her health more seriously in 2020.
Appearing on Drew Barrymore's talk show, Rebel said turning 40 inspired her to rethink her habits.
Speaking of her weight loss journey, Rebel said: "Drew, for the last few years I've been theming my years, so I had the Year Of Fun, last year I had the Year Of Love and this year I’m like, 'It’s going to be the Year Of Health,' because I turned 40 this year in March and I never really focused on my health which was probably obvious."
She shared how becoming famous internationally was so stressful and her health took a backseat.
"I was going all around the world, jet setting everywhere and eating a ton of sugar that was kind of my vice.
"I have a very sweet tooth, I love desserts. I’ve tried, like so many women out there, fads and diets and things before and I’m like I need to do a really holistic approach this time.
She then focused on the emotional aspects of her eating habits. "I think what I mainly suffered from was emotional eating and dealing with the stress of becoming famous internationally,” Rebel said.
"There is a lot of stress that comes with it and I guess my way of dealing with it was just like eating donuts."
"So I was working on the mental side of things of why was I doing that and why was I not valuing myself and having better self-worth. And then, also on the nutritional side my diet was mainly all carbs, which are delicious, but for my body type I needed to eat more protein," she explained.
"So I lost Drew, I think it’s like 40 pounds this year so far and I want to lose a few more," Rebel said as the audience began to cheer for her.
However, she's never going to take things too far, adding that she still loves her curves and won't go overboard.
"I love my curves and stuff, I don't think I'll ever go too skinny but I feel so much healthier," she said.
"And I don’t know whether it’s a thing with ladies when you turn 40, I feel like I really have come into my own now and not just with health but with my career.
"I feel more in control and I get to produce movies now which is amazing and kind of have more control of the content. I just feel like everything seems to be coming together, maybe I’m a late bloomer or something but I’m slowly getting it together."
Rebel recently finished filming a TV special with SAS Australia's Ant Middleton in Mexico, which will premiere next year and will see Rebel take a "journey of discovery" with physical tasks and in-depth conversations.
