Results

Daily Fat Intake Range (20% – 35% AMDR) 52 – 92 g/day
Daily Energy from Dietary Fat 472 – 826 kcal (9 kcal/g)
Saturated Fat Ceiling (<10% Energy) < 26 g/day (< undefined kcal)
Lipid Breakdown & Dietary Guidelines
Lipid Subtype Share of Calories Target Grams
Monounsaturated Fat (MUFA)
Heart-healthy fats found in extra virgin olive oil, avocados, almonds, and olives. Promotes HDL and reduces LDL.
 15% - 20% 39 - 52 g
Polyunsaturated Fat (PUFA)
Essential fats including Omega-3 (EPA/DHA/ALA) and Omega-6. Found in wild salmon, walnuts, chia, and flaxseeds.
 5% - 10% 13 - 26 g
Saturated Fat (Upper Limit)
Found in fatty meats, butter, cheese, and coconut oil. Excessive intake can elevate ApoB and LDL cholesterol.
 < 10% (or < 6% AHA) < 26 g (AHA: < 16 g)
Trans Fatty Acids
Industrial partially hydrogenated oils. Strongly correlated with cardiovascular inflammation; eliminate completely.
 < 1% (As close to 0 as possible) < 2 g

The Crucial Role of Dietary Lipids

Dietary fat delivers concentrated metabolic energy at 9 Calories per gram—more than twice the caloric density of proteins or carbohydrates. Far from being something to eliminate, healthy lipids are indispensable for human physiology, endocrine homeostasis, steroid hormone creation, and cell membrane fluidity.

Unsaturated "Healthy" Fats

Monounsaturated (MUFAs) and polyunsaturated fats (PUFAs) improve blood lipid profiles, increase endothelial nitric oxide production, and reduce coronary artery calcium progression. Sources include extra virgin olive oil, wild salmon, walnuts, chia seeds, and avocados.

Saturated & Trans Fats

While saturated fat is a natural constituent of dairy and meats, consuming excess saturated fat down-regulates hepatic LDL receptors, increasing circulating ApoB atherogenic particles. Industrial trans fatty acids should be entirely avoided due to their severe inflammatory impact.

Recommended Daily Guidelines

  • USDA Dietary Guidelines: 20% to 35% of total caloric intake from total fat.
  • American Heart Association (AHA): Saturated fat limited to under 5% to 6% of daily calories for individuals prioritizing cardiovascular risk reduction.
  • Omega-3 Fatty Acids: 1.6 grams/day for adult men and 1.1 grams/day for adult women (adequate intake of Alpha-Linolenic Acid).

Understanding your calculation

Method, example and limitations

How the calculation works

Fat grams are derived from the calories assigned to fat using approximately 9 kcal per gram, according to the selected energy target and proportion.

Example to check

An illustrative allocation of 450 kcal to fat corresponds to 50 g of fat.

Before using the result

Total grams do not describe the mix of unsaturated, saturated and trans fats or the overall food pattern. Individual dietary needs can differ from the modeled range.
