What are Fats?
Fats are one of the three main macronutrients (along with protein and carbohydrates) that provide energy to your body. Fats provide 9 calories per gram, making them the most calorie-dense macronutrient.
Fats play crucial roles in hormone production, nutrient absorption (especially fat-soluble vitamins A, D, E, and K), brain function, and maintaining healthy skin and hair. Despite their bad reputation, healthy fats are essential for optimal health.
Types of Fats
Saturated Fats
Found in animal products and some plant foods. Should be limited to less than 10% of total calories. Can raise LDL cholesterol when consumed in excess.
Examples: Red meat, butter, cheese, coconut oil
Unsaturated Fats (Healthy Fats)
Found in plant foods and fish. Beneficial for heart health, brain function, and reducing inflammation. Should make up most of your fat intake.
Examples: Olive oil, avocados, nuts, seeds, fatty fish
Trans Fats
Artificial fats found in processed foods. Should be avoided completely as they raise LDL cholesterol and lower HDL cholesterol.
Examples: Fried foods, baked goods, margarine (check labels)

Understanding Your Results
Daily Fat Intake
The total amount of fat (in grams) you should consume daily based on your calorie intake and selected percentage. This is calculated as: (Total Calories × Fat %) ÷ 9 calories per gram.
Calories from Fat
The number of calories that come from fat. This is calculated as: Total Calories × (Fat % ÷ 100).
Saturated Fat (Max)
The maximum recommended amount of saturated fat per day. Health guidelines recommend limiting saturated fat to less than 10% of total calories.
Unsaturated Fat
The recommended amount of healthy unsaturated fats. This is your total fat minus the maximum saturated fat allowance.
Meal Distribution
Suggested fat distribution across meals: Breakfast (25%), Lunch (35%), Dinner (30%), and Snacks (10%). This helps maintain steady energy levels and satiety.
Recommendations
Comparison of minimum (20%), moderate (30%), and high (40%) fat approaches. Choose based on your goals, activity level, and personal preferences.
Fat Intake Guidelines
Minimum (20%): Typically 40-60g per day. Suitable for very low-fat diets or those with specific medical conditions. May be difficult to maintain long-term.
Moderate (30%): Typically 60-90g per day. Balanced approach suitable for most people. Recommended for general health and moderate activity levels.
High (40%): Typically 90g+ per day. Suitable for ketogenic diets, very active individuals, or those with high calorie needs. Focus on healthy unsaturated fats.
Best Fat Sources
Monounsaturated Fats: Olive oil, avocados, almonds, peanuts, cashews. Support heart health and reduce inflammation.
Polyunsaturated Fats (Omega-3): Fatty fish (salmon, mackerel), walnuts, flaxseeds, chia seeds. Essential for brain function and heart health.
Polyunsaturated Fats (Omega-6): Sunflower oil, soybean oil, nuts, seeds. Important but should be balanced with omega-3s.
Saturated Fats (Limit): Red meat, butter, cheese, coconut oil. Consume in moderation, less than 10% of total calories.
Tips for Optimal Fat Intake
Prioritize Healthy Fats: Focus on unsaturated fats from plant sources and fish. These provide essential fatty acids and support overall health.
Limit Saturated Fats: Keep saturated fat intake below 10% of total calories. Choose lean protein sources and limit processed foods.
Avoid Trans Fats: Read labels and avoid foods with partially hydrogenated oils. Trans fats have no health benefits.
Balance Omega-3 and Omega-6: Aim for a ratio of 1:1 to 1:4 (omega-3:omega-6). Include fatty fish or omega-3 supplements if needed.
Include Fat with Meals: Fat helps with satiety and nutrient absorption. Include healthy fats in each meal for better satisfaction and vitamin absorption.
Important Notes
- Individual fat needs vary based on activity level, metabolism, body composition goals, and personal preferences.
- The calculator provides estimates. Monitor your progress and adjust based on your results, energy levels, and goals.
- Very low-fat diets (below 20%) may not be suitable for everyone and can affect hormone production and nutrient absorption. Consult with a healthcare provider or registered dietitian before making significant dietary changes.
