Example Calculations

1. Food Item Analysis

  • Serving Size: 100 g
  • Servings Consumed: 2
  • Calories per Serving: 250
  • Protein per Serving: 8 g
  • Carbs per Serving: 30 g
  • Fat per Serving: 10 g

Result:

  • Total Calories = 250 × 2 = 500 cal
  • Protein = 8 × 2 = 16 g
  • Carbs = 30 × 2 = 60 g
  • Fat = 10 × 2 = 20 g
  • Macro Ratio = 13% / 48% / 39% (P/C/F)

2. Daily Intake Calculator

  • Calories Consumed: 1800
  • Target Calories: 2200
  • Protein: 90 g
  • Carbs: 200 g
  • Fat: 60 g

Result:

  • Total Calories = 1800 cal
  • Remaining Calories = 2200 − 1800 = 400 cal
  • Macro Ratio = 20% / 44% / 30%

3. Macro Nutrient Calculator

  • Body Weight: 70 kg
  • Activity Level: Moderate
  • Goal: Muscle Gain

Result:

  • Total Calories ≈ 2500 cal
  • Protein = 168 g
  • Carbs ≈ 290 g
  • Fat = 70 g
  • Macro Ratio = 27% / 46% / 25%
