The same food can contribute very different calories at 50 g, 100 g or 200 g. The calculator scales the estimate to the portion you enter.
Know what’s
on your plate.
Build a meal ingredient by ingredient, set the portion you actually plan to eat, and get an instant estimate of calories, protein, carbohydrates and fat.
Add what you eat.
Search the food library, choose a portion in grams, then add as many ingredients as you need. You can also edit or remove items before reading your total.
Your meal
Use the result as an estimate. Food composition varies with recipe, cooking method, brand, moisture and portion size. This tool is for general nutrition education and is not a substitute for individualized medical or dietetic advice.
Calories are useful.
Context is better.
Oil, sugar, sauces, cooking losses and ingredient brands can shift the final number. Treat the total as a practical estimate, not a laboratory measurement.
Use the calculator to see how ingredients add up, then consider protein, fibre, food quality, satiety and the rest of your day—not calories alone.
