1. What Is Food Calorie Intake Calculation?

Food calorie intake calculation helps determine the energy content of food based on its quantity and calorie density. This is essential for maintaining a balanced diet and managing weight.

2. How Does The Calculator Work?

The calculator uses the calorie calculation formula:

\[ Calories = \frac{quantity \times kcal\ per\ 100g}{100} \]

Where:

\( quantity \) — Food quantity in grams (g)
\( kcal\ per\ 100g \) — Calories per 100 grams of food (kcal/100g)

Explanation: The formula calculates total calories by scaling the calorie density to the actual quantity consumed.

3. Importance Of Calorie Calculation

Details: Accurate calorie calculation is crucial for weight management, nutritional planning, and maintaining overall health. It helps track energy intake and supports dietary goals.

4. Using The Calculator

Tips: Enter food quantity in grams and calorie content per 100g. Both values must be valid (quantity > 0, kcal per 100g ≥ 0).

5. Frequently Asked Questions (FAQ)

Q1: Why calculate calorie intake?
A: Calculating calorie intake helps manage weight, plan meals, and ensure nutritional needs are met.

Q2: What is a typical kcal per 100g value?
