body images and self-esteem

I'm fat. I'm too skinny. I'd be happy if I were taller, shorter, had curly hair, straight hair, a smaller nose, bigger muscles, longer legs.

Do any of these statements sound familiar? Are you used to putting yourself down? If so, you're not alone. As a teen, you're going through a ton of changes in your body. And as your body changes, so does your image of yourself. Lots of people have trouble adjusting, and this can affect their self-esteem.
Why Are Self-Esteem and Body Image Important?

Self-esteem is all about how much people value themselves, the pride they feel in themselves, and how worthwhile they feel. Self-esteem is important because feeling good about yourself can affect how you act. A person who has high self-esteem will make friends easily, is more in control of his or her behavior, and will enjoy life more.

Body image is how someone feels about his or her own physical appearance.

For many people, especially those in their early teens, body image can be closely linked to self-esteem. That's because as kids develop into teens, they care more about how others see them.
What Influences a Person's Self-Esteem?
Puberty

Some teens struggle with their self-esteem when they begin puberty because the body goes through many changes. These changes, combined with a natural desire to feel accepted, mean it can be tempting for people to compare themselves with others. They may compare themselves with the people around them or with actors and celebs they see on TV, in movies, or in magazines.

But it's impossible to measure ourselves against others because the changes that come with puberty are different for everyone. Some people start developing early; others are late bloomers. Some get a temporary layer of fat to prepare for a growth spurt, others fill out permanently, and others feel like they stay skinny no matter how much they eat. It all depends on how our genes have programmed our bodies to act.

The changes that come with puberty can affect how both girls and guys feel about themselves. Some girls may feel uncomfortable or embarrassed about their maturing bodies. Others may wish that they were developing faster. Girls may feel pressure to be thin but guys may feel like they don't look big or muscular enough.
Outside Influences

It's not just development that affect self-esteem, though. Lots of other factors (like media images of skinny girls and bulked-up guys) can affect a person's body image too.

Family life can sometimes influence a person's self-esteem. Some parents spend more time criticizing their kids and the way they look than praising them. This criticism may reduce a person's ability to develop good self-esteem.

People may also experience negative comments and hurtful teasing about the way they look from classmates and peers. Sometimes racial and ethnic prejudice is the source of such comments. Although these often come from ignorance, sometimes they can affect another person's body image and self-esteem.
