Melissa McCarthy’s 50-pound low-carb diet weight loss wowed fans at the May 26 premiere of her movie “Spy” in Berlin.
McCarthy’s weight loss was due to a low carb, high-protein diet, Examiner reported.
“Melissa has been on a high-protein, low carb diet,” said a source. “She’s been making small changes and seeing big results.”
McCarthy’s weight loss motivation was a desire to be healthy for her daughters, Vivian and Georgette, with husband Ben Falcone.
Sources said McCarthy has no desire to be super-skinny, but merely wants to be healthier.
“Melissa knows that fans love her big and beautiful, and she’s not obsessed with dieting,” said the insider. “She’s just looking for a happy medium.”
McCarthy, who has been overweight most of her life, said she had tried many times to lose weight on various diets. With her low carb diet, it appears Melissa may soon reach her weight loss goals. McCarthy will roll out a plus-size clothing line this fall.
Other celebrities who have lost dramatic amounts of weight on low-carb diets include Kim Kardashian, Megan Fox and Tim McGraw, who lost 40 pounds with the Paleo diet and CrossFit workouts.

Low carb diets such as the Atkins, ketogenic and Atkins diets promote rapid weight loss by inducing the body to burn fat for fuel, said obesity expert Dr. Eric Westman, co-author of Keto Clarity.
Fitness expert Robb Wolf agrees. Studies show low-carb diets reverse type 2 diabetes, prevents heart disease, and promote rapid fast weight loss without hunger, said Wolf, author of the bestselling Paleo Solution.
