Understanding Macronutrients
Before using the calculator regularly, it’s helpful to understand the key nutrients displayed.
Calories
Calories measure the amount of energy food provides to the body.
- Eating more calories than you burn may lead to weight gain.
- Eating fewer calories than you burn may support weight loss.
Different foods provide different calorie densities.
Protein
Protein is essential for:
- Muscle growth
- Tissue repair
- Hormone production
- Immune function
High-protein foods help improve satiety and muscle recovery.
Examples:
- Chicken breast
- Eggs
Carbohydrates
Carbohydrates are the body’s primary energy source.
They support:
- Brain function
- Physical activity
- Daily energy levels
Examples:
- Rice
- Bananas
- Apples
Fat
Dietary fat supports:
- Hormone production
- Brain health
- Vitamin absorption
- Cell function
Healthy fats are important in balanced nutrition.
Formula Used in the Calculator
The calculator works using a proportional nutrition formula based on values per 100 grams.
Basic Formula
Nutrient Value=(100Quantity)×Nutrient Per 100g
Where:
- Quantity = entered food amount in grams
- Nutrient Per 100g = standard nutrition value
- Result = adjusted nutrition amount
Example Calculation
Let’s calculate the nutritional values for 200 grams of banana.
Nutrition Per 100g of Banana
- Calories = 89
- Protein = 1.1g
- Carbohydrates = 23g
- Fat = 0.3g
Step 1: Calculate Factor
Factor=100200=2
Step 2: Multiply Each Nutrient
Calories
89 × 2 = 178 kcal
Protein
1.1 × 2 = 2.2g
Carbohydrates
23 × 2 = 46g
Fat
0.3 × 2 = 0.6g
