How the fat target is calculated
The calculator starts with your calorie target and selected eating pattern. It converts the chosen percentage of calories into grams because each gram of fat provides about 9 kcal.
Why the type of fat matters
Unsaturated fats are found in nuts, seeds, fish, avocado and plant oils. Saturated fat is more concentrated in butter, ghee, fatty processed meats, coconut oil and many bakery foods. Trans fat should be kept as low as possible.
Using the per-meal number
The per-meal value is an average, not a strict prescription. A meal containing salmon or avocado may be higher, while another meal may be lower. The daily pattern matters more than making every meal identical.
When to seek personalised advice
Speak with a clinician or registered dietitian if you have abnormal cholesterol, pancreatitis, gallbladder disease, fat-malabsorption symptoms, diabetes or a medically prescribed diet.
Practical guide for using this result
How the target is calculated
Calories from fat are divided by nine because fat provides nine kilocalories per gram. The reference range and saturated-fat ceiling use separate percentages.
Using the per-meal number
The per-meal value is a planning average. One meal can be higher and another lower as long as the day remains balanced.
When the target needs personalisation
Lipid disorders, gallbladder or pancreatic disease, pregnancy and specialised therapeutic diets require individual guidance.
How to use the fat target without oversimplifying food
Dietary fat includes essential fatty acids and helps absorb fat-soluble vitamins. The goal is a balanced range with attention to type and portion, not the lowest possible number.
Choose mostly unsaturated sources
Use fish, nuts, seeds, avocado and measured plant oils regularly. These foods also contribute protein, fibre or micronutrients depending on the source.
Keep saturated fat in context
Butter, ghee, cream, fatty meats and many pastries can raise saturated-fat intake quickly. Smaller portions and less frequent use make the overall pattern easier to balance.
Watch total energy
Fat provides 9 kcal per gram, so oils, nut butters and fried foods can add energy quickly. Measuring for a week can reveal portions without requiring permanent tracking.
