Eating disorders can develop quietly, often beginning with subtle changes that are easy to miss. Understanding what to look for—and acting early—can make an enormous difference.
Adolescence is a uniquely vulnerable time. Hormones, body changes, social pressure, academic stress, and the deep desire to fit in all collide during these years. Layer onto this the influence of social media, diet culture, and—more recently—the isolation and anxiety many experienced during the pandemic.
Then add dieting.
Dieting is often the trigger.
Weight loss itself changes the brain in powerful ways. In a genetically predisposed child, this can set off an escalating cycle of restriction and preoccupation with food and weight. Over time, the eating disorder can begin to take on a life of its own.
I often describe it to families as a kind of “monster in the brain.” It drives thoughts and behaviors that are often compulsive around food and eating behaviors that are very hard for the child to resist.
Parents are often the first to notice subtle shifts in their child’s eating pattern. Trust your instincts.
Watch for things like: • Cutting out entire food groups such as carbs, fats, or desserts • Sudden rigidity around “healthy” eating • Avoiding foods they once loved • Increased or compulsive exercise • Growing preoccupation with weight, calories, or body image.
If you notice early warning signs, it’s important not to take a “wait and see” approach. Subtle changes can be the first indication that something more concerning is developing.
Pay attention if your child begins avoiding foods they previously enjoyed because they are “too caloric” or “unhealthy,” becomes increasingly focused on weight or calories, dramatically increases exercise, or develops anxiety and distress around meals.
If you’re seeing any of these changes, I encourage you to bring your child in to talk with us.
Early support can make all the difference. In many cases, when we catch these patterns early, we can intervene before the behaviors become more entrenched. With the right conversations and interventions, we can help a child return to a healthier, more balanced relationship with food and their body before they develop a full-blown eating disorder.
When a person develops an eating disorder, food can feel threatening. Hunger cues are often unreliable or disappear entirely. They truly cannot make healthy decisions about eating.
This means parents need to step in—not as enforcers, but as calm, steady leaders.
Provide structure around meals. Expect resistance. Stay compassionate but firm. Try to separate your child from the illness.
You are not causing this.
You are one of the most important parts of the solution.
Family-Based Treatment (FBT), also known as the Maudsley Method, developed by Christopher Lock and Daniel Le Grange, is one of the most effective treatments for adolescent eating disorders. It places parents in an active role helping their child recover nutritionally while avoiding blame and keeping the focus on fighting the illness—not the child.
This approach can be incredibly challenging. Refeeding a child who is terrified of food requires persistence, emotional strength, and support.
But it is also deeply hopeful—because it places healing power directly in the hands of the family.
One of the most important things I tell parents is this:
This is not your fault.
Eating disorders are complex and multifactorial. The families I see are almost always loving, thoughtful, and deeply committed to their children.
And recovery is absolutely possible.
If you are worried, trust that instinct. You do not have to wait for things to get worse.
Early intervention, strong parental involvement, and the right support can make all the difference.
