What is the Fat Intake Calculator?

The Fat Intake Calculator is a tool designed to estimate daily fat consumption based on weight, height, age, activity level, and dietary goals. Fat is an essential nutrient that plays a crucial role in energy storage, hormone production, and overall health. This calculator helps users determine the right amount of fat to consume based on their lifestyle and dietary preferences.

Fat Intake Calculation Formula

Basal Metabolic Rate (BMR) - Mifflin-St Jeor Formula:

For men: BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age) + 5

For women: BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age) - 161

Daily Caloric Needs:

Calories = BMR × Activity Multiplier × Weight Goal Adjustment

Daily Fat Intake:

Total Fat (g) = (Calories × Fat Ratio) ÷ 9

Fat Type Breakdown:

  • Saturated Fat = Total Fat × 30%
  • Monounsaturated Fat = Total Fat × 50%
  • Polyunsaturated Fat = Total Fat × 20%
