Health & safety

Form Zero provides general education, planning and estimates. It is not medical advice and is not a substitute for a doctor, registered dietitian or other qualified professional.

Check every estimate

Calories, macros, portions, supermarket matches and AI photo results can be wrong or incomplete. Confirm package labels, ingredient quantities and serving sizes before logging or acting on a result. Photo analysis always requires your review.

Allergies and dietary needs

Never rely on Form Zero alone to identify allergens or cross-contamination. Check labels and contact the manufacturer or retailer when needed. Tell a qualified professional about allergies, intolerances, medical conditions or prescribed diets.

Get professional advice

Form Zero is intended for adults aged 18 and over. Speak to a qualified professional before making major diet or exercise changes if you are pregnant or breastfeeding, have a history of disordered eating, diabetes, kidney or heart disease, take medication, or have any other health concern.

Use sustainable targets

Calorie and protein targets are starting estimates. Avoid extreme restriction, dehydration or rapid changes. Stop and seek appropriate help if you experience fainting, chest pain, severe weakness, persistent pain or other concerning symptoms. For an emergency, call 999 in the UK.
