Example Calculation

Adult Female Example

Profile: 30-year-old female, 65 kg, 165 cm, moderate activity

TDEE: ~2000 calories/day

Fat requirement (27.5%): 2000 × 0.275 = 550 calories from fat

Fat grams: 550 ÷ 9 = 61g fat per day

Saturated fat limit: 2000 × 0.10 ÷ 9 = 22g maximum

Understanding Dietary Fats

What Are Fats?

Fats are essential macronutrients that provide energy (9 calories per gram), support cell function, help absorb fat-soluble vitamins (A, D, E, K), and provide essential fatty acids your body cannot make.

Functions of Fats

  • Energy storage: Long-term energy reserve
  • Cell membranes: Maintain cell structure
  • Hormone production: Support hormone synthesis
  • Vitamin absorption: Help absorb fat-soluble vitamins

Optimal Fat Intake

Fat Calories = Total Calories × 0.275

Fat Grams = Fat Calories ÷ 9

Health Considerations

  • Quality matters more than quantity
  • Emphasize unsaturated fats
  • Limit saturated fat intake
  • Eliminate trans fats completely
