So what on Earth was I freaking out about?”  (Click through to read the body-positive advice Melissa McCarthy gave her pre-teen daughters.)

In 2019, Miranda Lambert got candid with Good Housekeeping about weight and body image: "I don't have any rhyme or reason to my fitness routine or dieting. I’ve been on every diet. Every time I did low-carb, I would gain [the weight] back so quickly," she said. "Sometimes I have a couple weeks where I just drink beer and eat cheeseburgers. And then I’ll go, 'That was fun, but my stuff doesn’t fit.' Then I’ll spend a month doing Pilates or riding a lot and running."

Shonda Rhimes is the mastermind behind some of our favorite TV shows, but even this superstar deals with insecurities and struggles with her weight and body image. When the producer and screenwriter shed 150 pounds, she felt as though people treated her like a different person. In a Shondaland newsletter, she wrote, "I did not do it because I thought I would become beautiful like in the movies,” Rhimes explained. “I did it because I could not walk up a short flight up stairs without stopping to take a break and wiping sweat from my brow. I did it because my body was physically rebelling against the brain that had been ignoring it for so long.”

Sara Rue has been open about her weight loss in the past, even being a spokesperson for Jenny Craig. In a 2015 interview with Cosmopolitan, she said: "Anyone who has ever tried to lose weight knows it's such an emotional, complicated thing. As an actor, there are certain roles that you really can't play or be cast in when you're overweight. But I don't want to sensationalize it; my weight loss was more of an internal thing, and it was about mentally and physically wanting to be in a place where I could feel really comfortable in my own skin."

In a 2022 interview with PEOPLE, America Ferrera got candid about working out. "I love moving my body. I try [to work out] once a day,"she said. "I think my relationship to moving my body and working out has really evolved, and I'm in a place where I just want to enjoy it. I want to have fun, I want to move because I can, because it feels good, and because it always makes my day better after I've done that."

On The Talk UK, she said, "I took it for four months and I lost 30 lbs., but like everything, there's always no quick recipe. I was very sick for a couple of months. The first couple of months, I just felt nauseous. Every day I felt nauseous, my stomach was upset, whatever."

Country singer Trisha Yearwood has been open over the years about her struggle with her weight and the yo-yo dieting she often found herself taking part in.

I walked and did the rowing machine. I built muscle by lifting weights and doing lunges and squats. I ate more protein, ate less sugar and drank no alcohol. I used an app called Happy Scale to track my daily weight. I switched to a standing desk and generally tried to stand and move more." 

Hilariously funny Mindy Kaling, who has also struggled with her weight and body image over the years admitted that the secret to her weight loss has been moderation and exercise. "Honestly, I didn't really do anything differently. I eat what I like to eat. If I do any kind of restrictive diet, it never really works for me. I just eat less of it... I wish there was something more juicy or dynamic about the way that I've lost a little bit of weight, but that's the way I've done it," she told Entertainment Tonight in 2020.
