Convert a percentage of daily calories into grams of fat, estimate a saturated-fat ceiling, and divide the result across meals.
Your estimate
30% of 2,000 kcal
| Total fat per meal | 17 g |
| Calories from total fat | 600 kcal |
| Saturated-fat ceiling | 22 g/day |
| Room for unsaturated fats | At least 45 g |
How the estimate works
Fat supplies approximately 9 calories per gram. The calculator multiplies daily calories by the chosen fat percentage, then divides by 9. The saturated-fat ceiling is calculated separately from total calories.
| Setting | Meaning | Example at 2,000 kcal |
|---|---|---|
| 20% total fat | Lower end of the adult reference range | About 44 g |
| 30% total fat | Middle planning value | About 67 g |
| 35% total fat | Upper end of the adult reference range | About 78 g |
| 10% saturated-fat ceiling | Maximum rather than a goal | About 22 g |
Focus on fat quality
Choose foods rich in unsaturated fats such as olive oil, nuts, seeds, avocado, and fish where appropriate. Limit foods high in saturated fat and avoid industrial trans fat. A healthy pattern also depends on total calories, vegetables, fruit, whole grains, protein foods, and fiber.
Frequently asked questions
Is dietary fat necessary?
Yes. Fat supplies energy, supports cell function, and helps absorb fat-soluble vitamins. The type and amount both matter.
Is the saturated-fat result a target?
No. It is an upper planning limit. Lower intake may be advised for some people.
Why does the calculator divide by nine?
Fat provides approximately nine calories per gram, compared with about four per gram for protein and carbohydrate.
Should I choose 20%, 30%, or 35%?
The choice depends on the overall eating pattern, energy needs, preferences, and professional advice. Thirty percent is a neutral middle example.
