Food education, with clear limits.
Last updated: 10 October 2026
General education
This website and its guides provide general information. They do not diagnose, treat or prescribe. Content has not been independently clinically reviewed. Do not use it to replace advice from a qualified clinician or registered dietitian.
Sardine nutrition and fasting
Sardines provide valuable nutrients, but this does not prove that a sardine-only fast produces a particular health outcome. Meals and guides are educational ideas, not a personalised fasting prescription. No particular weight loss, treatment effect or cure is guaranteed.
Medicines and individual needs
Speak with your healthcare team before fasting or substantially changing your diet if you take diabetes medicines. Do not stop or adjust prescribed treatment yourself. Seek individual advice for pregnancy, an eating disorder, kidney disease, gout, fish allergies or other circumstances that affect your diet.
Meal ideas and food safety
Meal ideas are not nutritionally analysed prescriptions. Adjust portions to your needs, check allergen labels and follow current food safety advice. Images illustrate the subject and are not proof of outcomes.
Urgent help
The website is not an urgent medical service. In a UK emergency call 999. For urgent medical advice, use NHS 111 or the appropriate local service.
Sources and corrections
We link evidence where relevant and distinguish it from practical suggestions. Please use the contact page to raise a correction.
