Food Calories Calculator

Calculate calories and nutrition for 484 foods. Search foods, build meals, track macros, and estimate daily calorie needs with BMR/TDEE calculator.

What is Food Calories Calculator?

A food calories calculator helps you track the calorie and macronutrient content of the foods you eat. With a database of over 484 foods across 17 categories, you can search for any common food, adjust portion sizes, and build complete meals to see total nutritional breakdown.

Understanding the calories in your food is essential for weight management, athletic performance, and overall health. This calculator provides detailed nutrition information including calories, protein, carbohydrates, fat, and fiber for each food item. You can also add custom foods to personalize your tracking.

Formula

Calories = (Calories per 100g × Weight in grams) ÷ 100
 
Macronutrient Energy:
Protein: 4 calories per gram
Carbohydrates: 4 calories per gram
Fat: 9 calories per gram
 
BMR (Mifflin-St Jeor):
Men: BMR = 10 × weight(kg) + 6.25 × height(cm) - 5 × age + 5
Women: BMR = 10 × weight(kg) + 6.25 × height(cm) - 5 × age - 161
 
TDEE = BMR × Activity Factor
Sedentary: 1.2, Light: 1.375, Moderate: 1.55, Active: 1.725, Very Active: 1.9

How to Calculate

  1. Search and select a food from the database of 484 foods.
  2. Enter the weight in grams for your portion.
  3. View the calorie and macronutrient breakdown.
  4. Add multiple foods to build a complete meal.
  5. Use the daily calorie calculator to estimate your BMR and TDEE.

Example

Select 'Chicken Breast' and enter 200g. The calculator shows 330 calories, 62g protein, 0g carbs, and 7.2g fat. Add 150g of rice (195 calories) and 100g of broccoli (34 calories) for a complete meal totaling 559 calories.

Common Use Cases

  • Tracking daily calorie intake for weight loss or gain
  • Building balanced meals with proper macronutrient ratios
  • Estimating daily calorie needs with BMR/TDEE
  • Comparing calorie content of different food options

Frequently Asked Questions

What is the difference between BMR and TDEE?
BMR is the calories your body burns at complete rest for vital functions only. TDEE is your total daily calorie burn including activity, exercise, and digestion. TDEE = BMR × activity factor. Use BMR as a baseline, but use TDEE for meal planning.
How accurate is the Mifflin-St Jeor equation?
The Mifflin-St Jeor equation is considered the most accurate BMR formula, with about 70% of people falling within 10% of their measured BMR. Individual variations in muscle mass, genetics, and hormones can affect accuracy.
Should I eat below my BMR to lose weight?
No. Eating below your BMR is generally not recommended as it can slow your metabolism and lead to muscle loss. Aim for a deficit from your TDEE (300-500 kcal below), not from your BMR.
How often should I recalculate my needs?
Recalculate whenever your weight changes significantly (every 5-10 kg), when your activity level changes, or every few months as you age. Your calorie needs change as your body changes.
Can I rely solely on this calculator for my diet?
This calculator provides an estimate based on standard formulas. Individual needs vary based on genetics, medical conditions, medications, and lifestyle. Always consult a registered dietitian or healthcare provider for personalized advice.
