Why teens need a different approach

Adolescence is the second biggest growth period after infancy. Calorie, protein, iron, calcium and vitamin D needs all rise significantly between the ages of 13 and 18. So does the social and emotional weight food carries. Teens are making more of their own food choices, eating away from home more often, and being bombarded with nutrition messaging from social media that is frequently wrong, sometimes harmful, and almost never evidence-based.

This is also when disordered eating most commonly emerges. As Beat highlights, any advice given to teens has to take that seriously. 'Healthy eating' advice that focuses on restriction, 'good' and 'bad' foods, or body shape can do real harm. The focus should be on adequacy, balance, and building a sustainable relationship with food that will serve a young person well into adulthood.

What a 14-year-old needs from nutrition guidance is fundamentally different from what a 7-year-old or a 30-year-old needs. The physiology is different, the psychology is different, and the social context is completely different. That matters in how I work.

What a balanced diet actually looks like for a teenager

I get asked this a lot, usually by parents who are worried their teen is living on toast and cereal. The reality is that a balanced teen diet doesn't need to look like an Instagram plate. It needs to reliably deliver enough energy, enough protein for growth and repair, adequate iron (especially for menstruating teens), calcium and vitamin D for bone development, and enough variety to cover micronutrient bases.

In practical terms, that usually means three meals and two to three snacks across the day. The NHS Eatwell Guide provides a useful framework: the balance of food groups matters, and what this looks like practically depends on the individual teen. It doesn't need to be complicated, and it absolutely doesn't need to involve superfoods, supplements, or restriction of any food group.

Where I often end up working with families is bridging the gap between what the evidence says teens need and what actually happens in a household where a teenager skips breakfast, buys lunch from the school canteen, and grazes all evening. That's normal teen behaviour and it's workable. The goal is making those patterns adequate, not making them perfect.

TikTok, Instagram, and YouTube are where most teens get their nutrition information now. Some of it is reasonable. A lot of it isn't. Clean eating, detox diets, 'what I eat in a day' content, gut health protocols, elimination diets presented as lifestyle choices, influencers selling supplements. The volume of unqualified nutrition advice reaching teenagers is genuinely concerning.

In my consultations, I spend a fair amount of time helping teens and their parents evaluate what they're seeing online. My approach isn't to ban social media or dismiss everything, it's to build critical thinking. Who is this person? Are they qualified? Is this advice based on evidence or on their personal experience? Would a registered dietitian say the same thing?

This matters because social media-driven restriction is a common pathway into disordered eating. A teen cuts out gluten because a TikTok said it causes inflammation. Then dairy. Then sugar. Before long, the list of 'allowed' foods is shrinking and anxiety around eating is growing. If your teen is increasingly rigid about food rules they've picked up online, that's worth a conversation, and potentially a consultation.

Puberty, growth spurts, and

Puberty changes everything about nutritional requirements. Energy demands shift significantly during peak growth. Iron requirements nearly double for girls once menstruation starts. Calcium needs peak during adolescence because this is when roughly 40% of adult bone mass is laid down. Protein needs increase to support muscle development and tissue growth.

What this means in practice is that a teen who was eating fine at 11 may genuinely not be eating enough at 14. Growth spurts bring increased appetite, and that appetite is usually appropriate. A teenager eating constantly isn't necessarily a problem. It's often their body doing exactly what it should.

If you're unsure whether your teen's eating is adequate for their stage of growth and development, this is exactly the kind of thing I assess in a consultation. A dietary review alongside growth data gives a clear picture.

Common questions

Energy needs vary significantly by individual, depending on age, sex, activity level, and stage of growth. Three meals plus snacks, with a balance across the food groups, is the general framework. Iron is particularly important for menstruating teens, and calcium matters for everyone during this bone-building window. A consultation determines what adequate intake actually looks like for your teen specifically.
The balance of food groups matters, and what this looks like practically depends on the individual teen. It doesn't need to look perfect at every meal. Adequacy across the week is the goal, and a consultation determines what that means for your teen specifically.
Protein needs increase during adolescence to support growth and development, and are higher again for athletes. The specific amount depends on the individual, and a consultation determines whether your teen's intake is adequate.
One that provides enough energy for growth, adequate calcium and vitamin D for bone development, sufficient iron (especially for girls who have started periods), and enough protein for tissue growth. Practically, this means regular meals, adequate portions, and variety without rigidity.
Yes, often. Especially during growth spurts. Appetite tracks growth and activity. A teenager eating constantly isn't a problem if their growth, energy, and wellbeing are good.
Supplement needs depend on the individual and are assessed in a consultation. Some teens benefit from specific supplements, but which ones and at what dose depends on their diet, health, and stage of development.
Multiple factors beyond food contribute to teen health, and the balance looks different for each individual. Health at 15 is about sustainable habits, not perfection. A consultation identifies what matters most for your teen specifically.
How food is discussed at home matters as much as what's eaten — a consultation covers practical communication strategies. If you notice increasing rigidity or anxiety around food, seek support early.
