General

Every figure produced by Calorie Deck is an estimate derived from population-level formulas. It is not medical advice, not a diagnosis, and not a personalised nutrition plan. Individual needs vary considerably, and no calculator can account for your full medical history, body composition or medication.

Photo-based calorie estimates

The Food Scanner produces AI estimates with large margins of error. Independent testing of commercial photo-based calorie apps has found systematic undercounting, largely because cooking oil, butter and sauces are invisible in a photograph yet contribute substantial calories. Treat every scanner result as an approximation.

Who should not rely on these tools alone

• Anyone who is pregnant or breastfeeding.
• Anyone with diabetes, kidney disease, an eating disorder, or another condition affecting diet.
• Anyone under 18 — the adult formulas used here do not apply to growing bodies.
• Anyone taking medication affected by caffeine, fluid or protein intake.

If you fall into any of these groups, consult a doctor or registered dietitian before acting on any number from this site.

Fitness and body composition

BMI, body fat percentage and ideal weight formulas describe statistical averages. They do not measure your health. Muscular individuals, older adults and people of different ethnicities all fall outside what these equations model well.

No professional relationship

Using this site does not create a doctor-patient, dietitian-client or any other professional relationship. We are not responsible for decisions you make based on the output.

Emergencies

If you are experiencing a medical emergency, contact your local emergency services immediately. Do not use this site for urgent health matters.
