In PEOPLE's Most Talked About Bodies
issue, Dancing with the Stars
pro Cheryl Burke
shared some news that she's proud of: She recently dropped 15 lbs.
Her secret? Tweaking her diet and amping up her gym routine with interval training – besides dancing, of course.
But despite the many positive online comments she's received about her fit frame, Burke also has had her share of detractors, who wondered whether the pressures of her business played a role in her weight loss – or even if she needed to shed some pounds to begin with.
Speaking out on her Facebook
page about her "public struggle" with her weight, Burke wants her fans to know that she's "thriving."
"My weight fluctuates, just like any other person's does, and there will always be critics," she writes. "You've got to tune out the other people and tune into what's going on inside. Love yourself. Nourish your body. Be kind to one another."
