Safe Weight Management for Teens: What Parents Need to Know

Weight is a sensitive topic for teenagers—and for good reason. In a culture obsessed with thinness, teens receive constant messages about how they should look. At the same time, rates of both obesity and eating disorders in adolescents are concerning.

This guide covers how to address weight concerns safely, focusing on health rather than appearance.

What You Need to Know AAP

The complexity of teen weight:

• Bodies change dramatically during puberty
• Weight gain is normal and expected during adolescence
• Growth spurts affect weight before height catches up
• BMI changes naturally during teen years
• Weight alone doesn't indicate health

The risks of focusing on weight:

• Dieting in teens is strongly associated with eating disorders
• Weight-focused approaches often backfire
• Body image issues are common and serious
• Teens who diet often gain more weight long-term
• Mental health is as important as physical health

What research shows:

• Family-based approaches work best
• Focus on behaviors, not numbers
• Health-centered approaches are safer than weight-centered
• Restriction typically doesn't lead to lasting change
• Environment matters more than willpower AAP

Red Flags: When NOT to Focus on Weight

Do not address weight if your teen:

• Is already dieting restrictively
• Shows signs of eating disorder
• Has poor body image
• Is depressed or anxious
• Has history of weight cycling

Signs of eating disorder:

• Significant restriction
• Binge eating
• Purging behaviors
• Obsession with weight or food
• Excessive exercise
• Dramatic weight changes
• Food rituals

If you see these signs, seek professional help immediately—not weight management guidance. AAP

Healthy Approach to Weight Concerns

Shift from weight to health:

• Focus on behaviors, not numbers
• Health markers beyond weight (energy, sleep, mood)
• What the body can do, not how it looks
• Long-term habits, not quick fixes

Family-based changes:

• Changes for whole family, not just one teen
• Model healthy behaviors yourself
• Change home environment together
• Don't single out the teen with weight concerns

Emphasize addition, not subtraction:

• Add physical activity they enjoy
• Add fruits and vegetables
• Add family meals
• Add sleep
• Add water

Behaviors that help:

• Regular physical activity (any movement counts)
• Eating breakfast
• Family meals
• Adequate sleep
• Limiting sugary drinks
• Reducing screen time
• Managing stress

What Parents Should NOT Do

Don't:

• Put your teen on a diet
• Comment on their weight or appearance
• Weigh them or encourage frequent weighing
• Restrict their food access
• Label foods "good" or "bad"
• Use food as reward or punishment
• Compare them to siblings or others
• Make exercise punishment

Don't say:

• "You should eat less"
• "You need to lose weight"
• "I'm worried about how much you eat"
• "Should you be eating that?"
• "You'd feel better if you were thinner"

Instead:

• "Let's go for a walk together"
• "I'm making a new recipe tonight—want to help?"
• "How are you feeling about school/activities/life?"
• "What physical activities do you enjoy?"

What Parents Should Do

Model healthy behaviors:

• Eat a balanced diet yourself
• Exercise for enjoyment, not weight control
• Don't diet or criticize your own body
• Speak positively about your body
• Enjoy all foods without guilt

Create a supportive environment:

• Keep nutritious food available
• Limit (don't ban) less nutritious options
• Make physical activity easy
• Prioritize family meals
• Support their activities and interests

Address stress and mental health:

• Emotional eating often underlies weight concerns
• Depression and anxiety affect eating patterns
• Ensure they have support
• Consider counseling if needed

Work with healthcare providers:

• Discuss concerns with pediatrician
• Get professional guidance before addressing weight
• Consider dietitian referral
• Monitor for eating disorders

Talking to Your Teen About Weight

If they bring it up:

• Listen without judgment
• Don't dismiss their concerns
• Don't agree they need to lose weight
• Redirect to health behaviors
• Explore feelings underneath weight concerns

If you have concerns:

• Discuss with pediatrician first
• Don't approach it as a weight conversation
• Focus on healthy family habits
• Lead with curiosity about their wellbeing
• Make changes for the whole family

Helpful responses:

• "I hear you're feeling frustrated. What's going on?"
• "Your body is doing exactly what it's supposed to during puberty"
• "I care about you feeling strong and healthy—what would help you feel that way?"
• "Let's find some activities we can do together"

When Professional Help Is Needed

Talk to your pediatrician if:

• Significant weight gain is occurring
• Weight is affecting health markers
• You're concerned about eating behaviors
• Your teen is distressed about weight
• You need guidance on approach

Types of professional support:

• Pediatrician for overall assessment
• Registered dietitian for nutrition guidance
• Therapist for emotional/behavioral aspects
• Family-based treatment if needed

What NOT to do:

• Don't try commercial weight loss programs
• Don't give supplements or diet pills
• Don't try extreme approaches
• Don't go it alone if struggling

What Other Parents Ask

Q: My teen's doctor said they need to lose weight. What do I do?
A: Work with the healthcare team on a safe approach. Focus on healthy behaviors for the whole family—not dieting for your teen specifically. Avoid restriction and weight talk. Consider a referral to a registered dietitian who specializes in adolescents.

Q: My teen wants to diet. Should I support this?
A: Don't support restrictive dieting for teens—it's associated with eating disorders and long-term weight gain. Instead, focus on healthy habits for the whole family. Discuss with your pediatrician if your teen is concerned about weight. AAP

Q: How do I help my teen lose weight without making them feel bad about their body?
A: Shift focus from weight to health behaviors. Make changes as a family, not just for them. Emphasize what bodies can do, not how they look. Add healthy habits rather than restricting. Never comment on their weight or appearance. Work with healthcare providers.

Q: My teen is teased about their weight. How do I help?
A: Validate their feelings without agreeing they should lose weight. Help them develop confidence beyond appearance. Address bullying with school. Consider counseling for support. Don't use this as motivation to diet—it can trigger eating disorders.

Q: Is bariatric surgery appropriate for teens?
A: In rare cases, bariatric surgery may be considered for teens with severe obesity and obesity-related health conditions who haven't responded to other approaches. This requires thorough evaluation by a specialized team. It's not appropriate for most teens. AAP

The Bottom Line

Addressing teen weight concerns requires focusing on health behaviors, not weight itself. Dieting is dangerous for teens and often backfires. Make changes as a family, model healthy behaviors, and work with healthcare providers. Watch for eating disorder signs. The goal is long-term health and wellbeing, not a number on the scale. AAP

Key points:

• Focus on behaviors, not weight
• Don't diet; don't talk about weight
• Make family-wide changes
• Model healthy behaviors
• Work with healthcare providers
• Watch for eating disorder signs
