How to Calculate Fat Intake
What is Fat Intake?
Dietary fat (9 kcal/g) is essential for fat-soluble vitamins, hormones, and brain health. Recommended intake is 20–35% of total calories, mostly from unsaturated sources.
Formula
Daily fat intake recommendation: 20–35% of calories; 1 gram fat = 9 kcal; Daily grams = (Daily calories × 0.25–0.35) / 9
- DailyCalories
- Daily calorie intake (kcal)
- FatPercent
- Target % of calories from fat (Percentage (20–35%))
- FatGrams
- Daily fat target (Grams)
Step-by-Step Guide
- 1Fat grams = (Calories × fat%) / 9
- 2Saturated fat: limit to < 10% of total calories
- 3Unsaturated fats (olive oil, avocado, fish) preferred
- 4Trans fats: minimise as much as possible

Frequently Asked Questions
Is fat unhealthy?
No. Essential for hormone production, cell membranes, vitamin absorption. 20–35% of calories appropriate. Type matters: unsaturated > saturated > trans fats.
What's the difference between fat types?
Saturated (meat, dairy): raises LDL cholesterol. Unsaturated (nuts, fish, oils): lowers LDL, raises HDL. Trans fats (processed): worst; increase LDL, lower HDL. Limit trans fats.
How much fat is too much?
> 35% of calories increases cardiovascular risk, obesity risk. < 20% may reduce satiety, hormone production (low-fat diets linked to mood/hormonal issues).
