Formula Used

Fat Percentage = (Calories from Fat ÷ Total Daily Calories) × 100

Where:

Calories from Fat = Total calories consumed from fat sources
Total Daily Calories = Total calories consumed in a day
Fat Percentage = Percentage of total calories that come from fat

Example Calculation

Real-World Scenario:

A person following a 2,000 calorie diet wants to ensure they're meeting dietary guidelines for fat intake.

Given:

Calories from Fat = 600 calories
Total Daily Calories = 2,000 calories

Calculation:

Fat Percentage = (600 ÷ 2,000) × 100 = 0.3 × 100 = 30%

Result: 30% of calories come from fat, which is within the recommended range of 20-35% according to dietary guidelines.
