    How to use the food calorie calculator

    Choose a food, set the number of servings and press Add. The list shows each item and a running total. Change your daily target to see how much room is left. If your food is missing, use the custom food box with the calories printed on the pack.

    Not sure of your target? Use the daily calorie calculator first. Most adults land between 1,600 and 2,800 kcal depending on size, age and activity.

    Calorie basics that matter

    • Carbohydrate and protein give about 4 kcal per gram, fat gives 9 and alcohol gives 7.
    • Oil, ghee and butter are the easiest hidden calories. One tablespoon adds about 100 to 120 kcal.
    • Liquid calories such as juice, cola and sweet tea do not fill you up the way solid food does.
    • Portion size changes the total more than the food choice. A large plate of rice can double the figure on the label.

    Meal timing and sleep

    A big meal in the last two to three hours before bed can raise body temperature and cause reflux, which makes it harder to fall asleep. Aim to finish your largest meal at least three hours before bedtime and keep late snacks light. The meal timing calculator works this out from your bedtime.

    A sample day of eating at about 2,000 kcal

    MealExamplekcal
    Breakfast2 egg omelette, 1 roti, tea with milk365
    Lunch1 cup rice, 1 cup dal, salad, yogurt704
    SnackBanana and a handful of almonds269
    DinnerChicken curry, 2 roti, apple635

    Total about 1,973 kcal. It is only an example of how portions add up, not a diet plan.

    Frequently asked questions

    How many calories should I eat a day?

    Most adult women need roughly 1,600 to 2,400 kcal and most adult men 2,000 to 3,000 kcal, depending on size and activity. The calorie calculator gives a personal estimate.

    Are the calorie values exact?

    No. They are typical averages based on public nutrition data such as USDA FoodData Central. Cooking oil, brand and portion size change real values.

    Does eating late affect sleep?

    A large meal close to bedtime can disturb sleep through reflux and a raised body temperature. Finish big meals about three hours before bed.

    Is this tool a diet plan?

    No. It is an estimating tool. For a medical condition, pregnancy or a very low calorie goal, speak with a doctor or registered dietitian.
