At some point, most of us have wished that we were thinner, more muscular, or better looking. After all, in today's world, we're constantly bombarded with images of celebrities and models. After a while, many people want to be like them or even believe they're happier because of the way they look. But according to experts, if you have these thoughts often, you may be in need of a body-image boost.

Body image, or the way a person thinks about his or her body and how it looks to others, can have major impacts on our self-esteem, our mood, and even our health. That's why it's important to accept the body you have. What's more, you may find that the assumptions fueling your body-image issues are unfounded: Even models, for example, aren't perfect—their jobs require that they stay super-skinny, so they're probably more worried about their bodies than you are.

Body-Image Boosters

If you often find yourself wishful thinking in front the mirror, follow these tips from the National Eating Disorders Association to improve your self-esteem. If you're continually bothered by your body image, be sure to consult your doctor.

1. Write it down. Make a list of your best qualities, such as loyalty, intelligence, humor, or creativity. Repeat these to yourself whenever you're feeling bad about your body.

2. Take stock. Think of three reasons why it's ridiculous to believe that beautiful people are happier or better. Remind yourself of these if you start to have doubts.

3. Minimize mirror time. It's unhealthy to spend hours scrutinizing every inch of your body. Instead, cut down on the time you spend in front of the mirror, and focus on things that make you feel good.

4. Prioritize. If you're dieting or exercising, make sure you're doing it for the right reasons. It's more likely that you'll stick with your routine if you can will help you recognize the rewards of feeling better and growing stronger, as opposed to achieving an appearance goal that may be impossible.

5. Wear comfortable clothes. Remember, you don't need to squeeze into the same jeans you wore five or 10 years ago. It's normal to grow as you age, so treat yourself to a new pair that fit comfortably. You'll feel better and have more confidence, knowing that you look good.
