At the age of 16, Danni Tabor landed a role that would dramatically change her life: She joined the cast of "Harry Potter" as Angelina Johnson — a Quidditch star and the future wife of George Weasley — and was thrusted into a world of fame and body scrutiny. 

Quickly, she became obsessed with the idea of using fitness (specifically, bikini competitions) to get skinny. But now, the scale means practically nothing to her.

"I wanted to love my body — I just didn't know what that meant truly until this last year," Tabor told Popsugar. "And I have been on this journey (consistently) since early 2014."

"I think subconsciously you wanted to 'fit in' to the TV and film world and unfortunately that meant being petite and skinny," she said. "The camera does add 10 pounds; I remember this ad I did — I walked away from camera and I looked (what I thought was) huge. It does affect your idea of normal. Essentially, though, my body-image issues weren't down to the industry alone. These were ideas I had from little events along the way of life."

So she began to prep her body for competition — which led to a lot of weighing-in and obsessing over the scale number.

And though she has gained 22lbs since her competing days, Tabor says she is far less obsessed with the scale number — because it has nothing to do with how healthy her body feels.

"You always think that if you weigh less and get to that magical number, you'll think less about your weight. But I in fact thought about that [lower] number more ... wanting to stay close to it, fearing it getting higher. I would fret each week seeing it go up. The mission to stay lean was always harder than getting there."

Tabor now focuses on promoting self love at every size, regardless of how much she weighs.

"I think weighing is a great tool, especially when you do want to build muscle or you are doing competitions. The scale and the number is not the problem at all — it's our attachment to that number and what that means to us. Fifty kg. was a magical number I held on a pedestal since I was 14. I didn't plan to get to 50 kg. for performance day, but that's around where I sat, and I remember being very pleased. It was because of the idea I had and what that meant to me. It's taken a year, but truly that number does not have the same connotation for me at all now."

And overall, she stressed the importance of allowing yourself to change — physically and mentally.

"We can change how we see our bodies and therefore how we feel," she wrote. "Fit and healthy and sexy and beautiful comes in all different forms. And your bod may take different forms in your own journey — none right or wrong."

Way to go, queen!
