Teen weight & nutrition

Meal regularity. Balanced intake without categorising foods as good or bad. Body neutrality rather than body shaming. Movement they actually enjoy rather than punitive exercise. Sleep, because sleep deprivation is linked to changes in appetite regulation and food choices. Stress management, because stress hormones can influence eating behaviours. Often more than half of the work isn't about food at all.

I work with the whole family, not just the teen. Singling a teenager out as 'the one with the weight problem' is counterproductive and often damaging. Changes to household eating patterns, family meals, how food is talked about at home, these are the levers that actually work. The teen doesn't need a different diet from the family. The family needs patterns that support everyone.

Body image is central to everything in this space. How a teen feels about their body affects what they eat, how they move, their mental health, and their willingness to engage with any kind of support. Teens who feel ashamed of their bodies are less likely to be active, more likely to restrict or binge, and more likely to avoid seeking help.

This means that any approach to teen weight has to be body-image-aware from the start. I don't weigh teens unless it's clinically necessary and we've talked about it first. I don't use language that frames their body as a problem to be fixed. I focus on what their body can do, how it feels, and what it needs, rather than what it looks like or how much it weighs.

If your teen is struggling with body image, whether or not weight is clinically concerning, that's worth addressing in its own right. As Young Minds emphasises, poor body image in adolescence predicts poor mental health outcomes regardless of actual weight status.

I want to be clear: there are situations where weight matters clinically. Rapid weight gain with no clear explanation, weight-related health markers that are outside normal range, or weight that's significantly affecting mobility or quality of life. In these cases, careful, sensitive, evidence-based work is needed, and it still doesn't involve restrictive dieting.

The approach in these situations is structured, multidisciplinary, and always mindful of the eating disorder risk that comes with weight interventions in teens. I work alongside GPs, paediatricians, and mental health professionals where needed, in line with NHS guidance, to make sure the whole picture is covered. This is exactly the kind of situation where a proper dietetic assessment helps, because it means the plan is evidence-based, individually tailored, and safe.
