Is there too much pressure put on girls to have "perfect" bodies? What are solutions for 2-3 problems related to this topic?

I think you're inquiring about whether there is too much pressure on girls to have "perfect" bodies; in response to this question, I would say yes, absolutely. We live in a time period in which print media, social media, movies, TV, and similar forms of entertainment are plentiful and regularly glorify a thin but voluptuous body image that is unattainable for many women. This truth can be ascertained objectively by perusing the magazines in a supermarket checkout line, scrolling through trending images on Instagram, or scanning promotional posters of the current movie lineup at any theater. Although there are famous, well-loved women who do not fit into the thin but voluptuous body type, the majority of images intended to appeal to media viewers consist of women who do posses this "ideal" body, which can cause women to feel pressured to conform to the image.
Eating disorders can be directly related to the pressure of having a perfect body. This illness often manifests either as bulimia nervosa, in which a person binges on large amounts of food and then forcefully expels it, or as anorexia nervosa, in which a person severely restricts the amount of food consumed. Eating disorders can be fatal, and they often manifest in people with distorted body images. The social and psychological risk factors that contribute to these diseases are undoubtedly exacerbated in an environment where being extremely thin is glorified, thus controlling exposure to media that glorifies an unhealthy body image and focusing on healthy, realistic expectations in the first place could be helpful to those at risk for eating disorders.
Bullying can be related to body image and body type, as those who are overweight or underweight are at a high risk of being targets. In a world in which a perfect body type is glorified, while other body types are commonly portrayed as less desirable or beautiful, those who do not fit the ideal image are natural targets for bullies motivated by social, personal, or cultural issues. A targeted change in popular media as a whole, as well as campaigns (both on a mass level and in individual schools or homes) that promote healthy and diverse images of women would be an excellent way to instill confidence in those who don't fit into an ideal mold, as well as to educate everyone regarding the equal worth and beauty possessed by all women.
