You know when you meet a health care professional and you have that feeling of, “Wow, I love the way they communicate! There’s kindness, clarity, and respect”? I hope you say yes!

Well, my guest on my podcast, and the blog this week is exactly that type of provider. Dr. Jennifer Gaudiani (who is called Dr G by her patients) is an internist, author, and a renowned eating disorder expert.

The podcast released yesterday is titled: Social Media’s Influence on Eating Disorders: Insights from Dr. G. 

I highly recommend it for you and any teens in your life. Please also know the conversation and this blog includes discussion of eating disorders, body image, and related experiences, so please read or listen with care. And if you or someone you love is affected by these issues you can find a list of support resources below.

In this blog, I highlight a few key points made by Dr. G, regarding media influences and disordered eating. This goes beyond all the skinny images that abound. Things like “SkinnyTok,” which was recently banned by TikTok but is still omnipresent.

In the pod, you’ll hear some fascinating and very helpful examples of how Dr. Gaudiani talks with teens who are experiencing eating disorders. Listeners will definitely notice that her style of talking with teens applies to all sorts of situations, not just around this topic. Give it a listen to see what I mean.

How social media messages around “healthy” eating and exercise can be detrimental

In the podcast, Dr. Gaudiani talks about how to untangle the nuances behind eating disorders, distinguishing them from disordered eating, which can often affect far more teens. She also talks about the underrecognized problem of compulsive exercise.

Youth are getting all sorts of “health” messages online, but when does what they see and hear start leading them into unhealthy thinking and behaviors?

Dr. G addresses how platforms like TikTok and Instagram often become breeding grounds for harmful practices disguised as wellness tips. These influences can lead teens down a dark path of food restriction and body insecurity, fueled by an incessant cycle of comparison and the desire for acceptance. In the podcast, she says,

“I see teens who find food rules on TikTok who say, ‘Here’s what I eat in a day,’ and they follow some influencer who looks slender, appealing, accomplished — someone giving a series of food rules that are really arbitrary but couched in anti-scientific terms, like, ‘I’m not dieting, I’m just watching my inflammation,’ or ‘I’m not dieting, I just want better energy.’
Inevitably, there’s a meaningfully restrictive aspect to whatever’s being recommended, because that’s what’s being influenced: Do as I do, and you’ll look like me, or have the power that I have.”

She goes on to say:

“It’s when there starts to become an inability to shift off those rules — when the kid starts to get really triggered and anxious and resistant when something else is offered, when eating spontaneously occurs, when something unexpected like, ‘Hey, let’s go out to dinner tonight,’ happens — and they get that clench.
That’s when I would start to say, we need to look a little more into this, ’cause maybe this has got its hooks too deep.”

It’s crucial that we talk with kids, starting even at age 9 or 10, about how tricky it can be to know what is actually healthy information versus unhealthy information. Even if kids don’t have social media per se, many are on YouTube, or their friends are on social media, and that info gets shared in lunchrooms and group chats.

Let me end with one more excellent point Dr. Gaudiani made — a great one to discuss with youth:

“And the truth is, historically, so many so-called food and body influencers fall out of the public eye. A number of them come back later and say, ‘I’m really sorry. I was peddling something that made me so sick.
In my vegan recommendations, in my intensive vegetarian recommendations, I actually had to stop working and tend to my health. So I’m so sorry.’”

Questions to get the conversation with your group or family:

  1. Have you ever come across posts or videos that give strict food or exercise rules? How do you decide whether that advice is actually healthy or not?
  2. What do you think Dr. Gaudiani meant when she said teens can get hooked on certain food rules?
  3. Have you ever seen influencers talk about health and later admit it was actually harmful to them?

Bringing Teen Therapy Out of the Shadows

Mental Health Awareness Month is a perfect time to spotlight an often-overlooked topic: the role of families in teen therapy. Today I recall my recent conversation with Dr. Laura Kastner, acclaimed author and experienced family therapist, who shares why therapists should push for family participation, even when a teen resists. I also share a personal moment from Screenagers Next Chapter, when my daughter and I did family therapy together—a powerful reminder of what’s possible.
