How we calculate
Where the numbers come from, how far to trust them, and what to do if you spot a mistake.
1. Where the numbers come from
Calories, protein, carbs, fat and fibre are currently estimates for a typical home-cooked portion. They are not lab results. A food marked "Verified" has been checked by a named specialist; anything without that mark is still an estimate.
2. Sources we check against
During review we compare with recognised food composition tables such as USDA FoodData Central, India's IFCT and the Bangladesh food composition table from INFS, University of Dhaka. Home cooking varies with oil, method and portion, so a small gap is always possible.
3. Portions
Each food lists a portion such as one plate of rice or one egg. If your portion is bigger or smaller, scale the numbers.
4. How "walk it off" is calculated
We assume a 70 kg adult walking briskly burns about 5.3 kcal per minute (MET about 4.3). Minutes = food calories รท 5.3. Your weight, age and pace will differ, so treat it as a rough guide.
5. The calorie calculator formula
We use the Mifflin-St Jeor equation for basal metabolic rate and multiply by an activity factor. This is a rough guide for healthy adults and does not apply in pregnancy, illness or special conditions.
6. What we do not do
We do not give medical treatment or patient diet charts, children's diets, pregnancy advice, or medicine or supplement advice. For these, see a doctor or dietitian.
7. Found a mistake?
If a number looks wrong, tell us. We will check it and update it with a date.
