"There's an epidemic in our country of girls and women feeling bad about themselves based on what .5 percent of the human race looks like," McCarthy, 45, said. "It starts very young. My message is that as long as everybody's healthy, enjoy and embrace whatever body type you have."
The actress is willing to do just about anything to make sure criticism doesn’t reach her two daughters Vivian, 8, and Georgette, 6.
"Give me your best punch in the face and I'll take that punch, rather than have my kid feel bad about herself," McCarthy added.
Instead of just complaining about the problem, McCarthy has taken matters in her own hands, designing fashionable clothes for women of all shapes and sizes.
"A good portion of women in America are size 14 and higher. I just try to make clothing that'll make all women feel really good," she shared.
"When I feel good about my clothes, I'm more patient with my kids," she adds. "I don't beep at the guy in his car texting in front of me," said McCarthy. "I look at the world a little differently. The small happy moments add up. A little bit of joy goes a long way."
