Different Types of Fat

Unhealthy Dietary Fat
Should be limited or avoided

Saturated Fat

Mostly found in animal sources (red meat, poultry, dairy) and some nuts, oils, and seeds. Raises LDL cholesterol and can increase the risk of cardiovascular disease and type 2 diabetes.

Limit: Less than 10% of daily calories (ideally <7%)

Trans Fat

Found in processed foods through partial hydrogenation. Not essential and has no known benefits. Increases risk of coronary artery disease, obesity, and type 2 diabetes.

Recommendation: Minimize or avoid completely

Healthier Dietary Fat
Beneficial in moderation

Monounsaturated Fat

Found in olive oil, avocados, nuts, and seeds. Can help reduce LDL cholesterol while potentially increasing HDL cholesterol levels.

Sources: Olive oil, avocados, almonds, peanuts

Polyunsaturated Fat & Omega-3

Found in plant-based foods, oils, and fatty fish. Omega-3 fatty acids have been found to decrease the risk of coronary artery disease.

Sources: Fatty fish, flaxseeds, chia seeds, walnuts, sunflower oil

How Our Fat Intake Calculator Works

Our fat intake calculator estimates the amount of dietary fat you should consume on a daily basis based on your Basal Metabolic Rate (BMR) and activity level. The calculator uses the Mifflin-St Jeor or Katch-McArdle equations to calculate your BMR, then multiplies it by an activity factor to determine your Total Daily Energy Expenditure (TDEE). The calculator also considers the maximum recommended levels of saturated fats you should consume to reduce the risk of heart disease.

Different Types of Fat

Fat, along with carbohydrates and proteins, is one of three macronutrients that provide the energy necessary for a person's metabolic system to function, and can be acquired through consuming various foods. There are numerous types of dietary fat, including saturated fat, trans fat, monounsaturated fat, polyunsaturated fat, and omega-3 fatty acids. While dietary fat is essential to proper body function, excess dietary fat leads to weight gain, and excess weight is linked to poor health outcomes. Refer to the Body Fat Calculator for more information regarding excess fat.

Unhealthy Dietary Fat

Saturated Fat

Certain types of dietary fat are more harmful than others. Saturated fat is one of the more harmful types of fat and is mostly found in sources of food derived from animals; red meat, poultry, and dairy products. Saturated fat can also be found in various nuts, oils, and seeds. There exists some controversy surrounding the effects of saturated fat on the risk of disease, but saturated fat is largely considered harmful. Sources such as Mayo Clinic and the American Heart Association, among many others, recommend a diet that is low in saturated fat, arguing that saturated fat raises the levels of "bad" low-density lipoprotein (LDL) cholesterols, and can increase the risk of cardiovascular disease and type 2 diabetes.

Trans Fat

Trans fat is a type of dietary fat that occurs naturally in small amounts in some foods, but most of the trans fat that people encounter is the result of a food processing method called partial hydrogenation. Highly processed foods, such as fast food, tend to have high amounts of trans fats, and reducing consumption of these types of food is generally beneficial to a person's health.

Trans fats are commonly regarded as the "worst" type of dietary fat, are not essential, and have no known benefits to human health. Trans fats have been shown to increase the risk of coronary artery disease by increasing levels of LDL cholesterols, while decreasing the levels of "good" high-density lipoproteins (HDL) cholesterols. It can also increase the risk of obesity and type 2 diabetes. Note that by law, a serving of food that contains less than 0.5 grams of trans fat can be labeled as having 0 grams of trans fat. It is possible to fully avoid trans fat from processed foods by ensuring that any food labeled as having 0 grams of trans fat also has no ingredient involving the term "partially hydrogenated."

Healthier Dietary Fat

Monounsaturated and polyunsaturated fat are two types of unsaturated fat that are typically found in a variety of foods and oils, with polyunsaturated fat more commonly being found in plant-based foods and oils. Studies have shown that both of these types of unsaturated fat, in small amounts, can help reduce LDL cholesterol, while potentially increasing HDL cholesterol levels in the bloodstream. Furthermore, omega-3 fatty acids, a type of polyunsaturated fat that is rich in certain fish, have been found to decrease the risk of coronary artery disease.

Daily Fat Intake

So far, there is no golden rule guiding daily fat intake. Generally, some fat intake, particularly intake of unsaturated fats, can have beneficial effects on the human body. Children especially need some fat in their diets to be healthy. It's generally recommended that a child drink whole milk instead of low fat or no-fat milk once they stop breastfeeding. However, any type of fat, including these healthier dietary fats, can have negative effects when consumed in excess. Below are some guidelines regarding the amount and types of fat a person should consume:

  • Consume less than 10% of daily caloric needs in the form of saturated fats. Limiting consumption to less than 7% has been shown to reduce the risk of heart disease.
  • Replace saturated fats with unsaturated fats if possible.
  • Minimize consumption of trans fats.
  • Consume less than 300 mg of dietary cholesterol each day.

Fat Intake Calculator Examples

Example Calculation
Calculate fat intake for a 25-year-old male using Mifflin-St Jeor Equation

Input Values:

  • Age: 25 years
  • Gender: Male
  • Height: 180 cm
  • Weight: 60 kg
  • Activity: Light (1-3 times/week)
  • Formula: Mifflin-St Jeor

Calculation Steps:

  1. Calculate BMR: 10(60) + 6.25(180) - 5(25) + 5 = 1,605
  2. Apply activity multiplier: 1,605 × 1.375 = 2,207
  3. Calculate TDEE: 2,207 calories/day
  4. Recommended fat: 30% of calories = 662 calories
  5. Convert to grams: 662 ÷ 9 = 74g
  6. Saturated fat limit: 7% = 154 calories = 17g

Result: Daily Calories = 2,207 | Total Fat = 74g (30%) | Saturated Fat Limit = 17g (<7%)

Recommended range: 49g - 86g per day (20-35% of calories)

Female Example

30-year-old female, 165 cm, 55 kg, moderate activity

Calories: ~1,900 | Fat: ~63g

Heart Health Focus

Limit saturated fat to <7% of calories

Replace with unsaturated fats
