The dietitian behind it
Every guide here is shaped by a registered dietitian's standard of care — evidence first, real food second, jargon never. No personalities to follow, no miracle plans to sell. Just nutrition you can act on today, wherever you are.
What 'registered dietitian' actually means
In the UK, dietitian is a title protected by law. You can only use it if you're registered with the Health and Care Professions Council (HCPC), having completed an approved degree and met formal standards of proficiency. It is the only nutrition title with statutory regulation behind it — which is why we lead with the standard rather than a face.
Dietitian Without Borders is written and reviewed against that standard, with an added specialism in sports and endurance nutrition. We don't invent celebrity experts or borrow credentials we don't hold. When a page says something works, it's because the evidence — not a brand — says so.
How we work
Every guide on this site runs through the same five-step process a registered dietitian uses in practice — adapted for a public resource rather than a clinic.
Start from the question, not the trend
We write to a real need — fuelling a marathon, settling a sensitive gut, eating well plant-based — instead of chasing whatever's loud this week.
Anchor to primary evidence
We build from registered-dietetics bodies, peer-reviewed sports science, NHS, Coeliac UK, Monash FODMAP, IDDSI and Diabetes UK — and we cite the figures we use.
Translate into real food and numbers
Guidance only helps if you can act on it, so we put macros, intake ranges and portion examples into plain language and clear charts.
Respect the limits of an explainer
We explain; we don't prescribe. For anything clinical — a diagnosis, a medication interaction, a feeding plan — we point you to your own care team.
Review and keep it current
Guidelines move. Pages are written to be checked and refreshed as the consensus shifts, not frozen at first publish.
Fuelling figures we plan around
A worked example of evidence into practice: carbohydrate targets during endurance exercise, drawn from joint guidance by the Academy of Nutrition and Dietetics, Dietitians of Canada and the American College of Sports Medicine. Single carbohydrate sources cap oxidation near 60 g/hr; glucose–fructose mixes unlock the higher end.

“We'd rather give you one accurate number you can use tomorrow than ten confident claims you can't trust. The register, the citations and the caution are the whole point.”
About the practitioner perspective
Why is there no named dietitian on the page?
Because the standard matters more than a personality. We speak as 'a registered dietitian' and 'the Dietitian Without Borders team', and we never invent a name, a face or credentials we don't hold. What you can rely on is the HCPC-level standard of proficiency the content is written and reviewed against.
What's the sports-nutrition specialism about?
Alongside general registered-dietetic practice, our work leans into endurance and sports fuelling — carbohydrate periodisation, hydration, protein for active adults (the 1.2–2.0 g/kg/day evidence range) and race-day timing. You'll see that depth most in our endurance and energy-snack guides.
Who writes the recipes and guides?
They're authored and reviewed to dietetic standards: built from primary evidence, tested for everyday practicality, and written in plain British/international English. Macros and nutrition figures are researched, not guessed.
Is this medical advice?
No. These are explainers, not prescriptions. They're a strong starting point for understanding nutrition, but for diagnosis, medication or a personalised clinical plan — including dysphagia, diabetes or home tube feeding — please work with your own registered dietitian or care team.
