Food calories by item

Food Calorie Calculator

Use this food calorie calculator when you already know the food on your plate and want a fast calorie and macro estimate by grams, ounces, or servings. It is useful for checking single ingredients, building meals, and comparing manual entries with an AI photo calorie estimate.

Calculate food calories

By portion

Pick a common food, then enter either grams, ounces, or a serving count. The calculator scales calories, protein, carbs, and fat from a 100 g reference so the math stays visible and easy to adjust.

Food entries are practical estimates for planning. Brand recipes, added oil, sauces, cooking loss, and restaurant portions can change the final number.

Calories and macros

Estimate

Results appear after you calculate

You will see calories, protein, carbs, fat, and a table row for the selected portion.

How this food calorie calculator works

The page is designed for a different intent than a photo calorie counter. Instead of identifying food from an image, it helps you calculate a known food item quickly and understand which number changed.

Step 1

Choose the closest food entry

Start with the item that best matches what you ate. Plain cooked chicken, rice, eggs, fruit, oats, yogurt, potato, and oils cover many meal-building situations, and each entry can be scaled to your actual portion.

Step 2

Enter the real portion

Use grams if you weighed the food, ounces if your scale uses imperial units, or servings if you only know the common serving size. Grams are usually the most consistent option for calorie tracking.

Step 3

Adjust for extras

The result covers the selected food only. Add cooking oil, sauces, cheese, sugar, dressings, or toppings as separate items because small extras can change a meal total quickly.

Practical food calorie examples

Use the calculator when a quick food item estimate is more reliable than guessing from memory.

Meal prep

Scale cooked rice accurately

If your container has 240 g cooked white rice, enter 240 grams instead of choosing one generic cup. This gives a clearer calorie and carb estimate for meal prep.

Hidden calories

Track oil separately

Olive oil is calorie dense. If vegetables were cooked with one tablespoon of oil, add the oil entry separately rather than expecting the vegetable entry to include it.

Photo check

Compare with a meal photo

Use the AI photo calorie calculator for a mixed plate, then check major items here when you know a measured portion and want to refine the estimate.

Common food calorie table

The table shows the reference foods used by the calculator. Values are per 100 g in the data model, while the serving text gives a practical household reference.

Food Reference serving kcal / 100 g Protein Carbs Fat
Chicken breast, cooked 100 g cooked 165 31 0 3.6
White rice, cooked 1 cup cooked (158 g) 130 2.7 28 0.3
Brown rice, cooked 1 cup cooked (195 g) 111 2.6 23 0.9
Egg, whole 1 large egg (50 g) 143 12.6 0.7 9.5
Salmon, cooked 100 g cooked 208 20 0 13
Banana 1 medium (118 g) 89 1.1 22.8 0.3
Apple 1 medium (182 g) 52 0.3 13.8 0.2
Avocado 1/2 avocado (100 g) 160 2 8.5 14.7
Oats, dry 1/2 cup dry (40 g) 389 16.9 66.3 6.9
Greek yogurt, plain 170 g cup 73 10 3.9 1.9
Potato, baked 1 medium (173 g) 93 2.5 21.2 0.1
Olive oil 1 tbsp (14 g) 884 0 0 100

Accuracy notes and edge cases

A food calorie calculator is only as good as the food match and portion estimate. Use these checks before treating the number as exact.

Cooked vs raw

Do not mix cooked and raw entries

Rice, pasta, meat, and potatoes change weight during cooking. If you weigh cooked rice, use a cooked rice entry. If you weigh raw oats, use the dry oats entry.

Restaurant food

Recipes vary by brand

Restaurant and packaged foods may use different sauces, breading, oil, or serving sizes. Use the result as a planning estimate unless you have a nutrition label.

Meal totals

Build mixed meals item by item

For bowls, sandwiches, salads, and stir-fries, calculate the main ingredients separately. This is usually more reliable than forcing the whole meal into one generic food entry.

Nutrition data references

The calculator uses standard calorie and macro scaling. These sources are useful when you need to verify exact branded foods or understand nutrition label rules.

Food Calorie Calculator FAQ

Direct answers about food portions, calories, macros, and when to use a photo calculator instead.

What is a food calorie calculator?

A food calorie calculator estimates calories and macros for a known food item after you enter the portion size. It is useful when you know what the food is but do not want to do manual nutrition math.

Should I use grams or servings?

Use grams when possible because it is the most consistent input. Servings are convenient, but one real serving may be larger or smaller than the reference serving.

Why is oil so high in calories?

Pure fats such as olive oil provide about 9 calories per gram, while protein and carbohydrates provide about 4 calories per gram. That is why a small spoon of oil can change a meal total.

Can this calculate calories for a whole recipe?

Use it item by item: calculate each ingredient, add the calories together, then divide by the number of portions in the recipe.

When should I use the AI photo calorie calculator instead?

Use the photo calculator for mixed plates, restaurant meals, or food you cannot identify confidently. Use this page when you know the food and portion.

Are these calorie numbers exact?

No calorie calculator is exact. Food variety, moisture, cooking method, brand recipe, and weighing error all matter. Treat the result as a practical estimate for tracking.
