It's a compelling demonstration that things aren't always what they appear in the world of social media, advertising, video games, pop culture and even sport.

And yet such spheres can heavily influence body satisfaction and self-esteem, clinical psychologist Suzie Rhydderch told a Border forum on Tuesday.

Helping children and teens navigate the pitfalls of society's preoccupation with perfection was among the topics discussed at the parent information session hosted by The Scots School Albury.

About 70 people attended the forum presented by Ms Rhydderch on behalf of The Butterfly Foundation, experts in supporting people affected by eating disorders and body image issues.

In addition to tips on helping children build body confidence and warning signs for eating disorders, the forum highlighted the challenge of counteracting media messages.

Ms Rhydderch acknowledged people of all ages were "bombarded" by unhealthy and unrealistic body comparisons in the media.

"It's the promotion of appearance-based ideals and a diet culture," she said.

"It's where self-worth is determined by your size, weight and shape and that the way we look will determine whether we are liked or successful in life."

Ms Rhydderch said parents and teachers should encourage children to look through a "critical lens".

"Go through who they are following, what empowers them or triggers negative feelings; and discuss unfollowing or having a break from social media," she said.

Parents have a critical role in modelling and influencing the language and attitudes around body esteem, according to Ms Rhydderch.

Avoiding talk about diets or "naughty" eating; praising character rather than appearance; and focusing on the "incredible" things a body can do, rather than how it looks are all useful tools in empowering a young person.

"Just changing one thing can enact change," she said.
