Fat Intake Calculator - Calculate Your Daily Fat Needs
Calculate your optimal daily fat intake based on your goals, with detailed breakdown of saturated, monounsaturated, and polyunsaturated fats.
About the Fat Intake Calculator
Our Fat Intake Calculator is a comprehensive tool designed to help you determine your optimal daily fat needs based on your age, gender, body measurements, activity level, and specific goals.
This calculator uses the Mifflin-St Jeor equation to calculate your Basal Metabolic Rate (BMR), then applies your activity factor to determine Total Daily Energy Expenditure (TDEE). Based on your goals, it calculates your target calories and provides a detailed breakdown of recommended fat intake.
The calculation follows evidence-based guidelines:
• Total fat: 20-35% of daily calories
• Saturated fat: <10% of daily calories (max 22g)
• Monounsaturated fat: ~45% of total fat
• Polyunsaturated fat: ~40% of total fat
• Trans fat: <5% of total fat (max 2g)
Our tool goes beyond basic calculations to provide ApoB risk assessment, 90-day health simulation, and practical food recommendations to help you achieve your health goals.
- Personalized fat intake goals based on your profile
- Detailed breakdown of different fat types
- ApoB risk assessment for cardiovascular health
- 90-day health outlook simulation
- Practical healthy food recommendations
- Support for both metric and imperial units
Frequently Asked Questions
How much fat should I eat per day?
Most adults should get 20-35% of their daily calories from fat. The exact amount depends on your age, gender, body weight, activity level, and goals. For a 2000 calorie diet, this is about 44-78 grams of fat per day.
What are the different types of fat?
The main types are saturated (animal products, coconut oil), monounsaturated (olive oil, avocados), polyunsaturated (nuts, fatty fish), and trans fats (processed foods). Saturated and trans fats should be limited, while unsaturated fats are considered healthier.
How does saturated fat affect ApoB?
Saturated fat can increase levels of ApoB-containing lipoproteins, which are associated with increased cardiovascular risk. The WHO recommends limiting saturated fat to less than 10% of daily calories.
What are good sources of healthy fats?
Excellent sources include avocados, olive oil, fatty fish (salmon, mackerel), nuts, seeds, and nut butters. These provide monounsaturated and polyunsaturated fats, including Omega-3 fatty acids.
Can I calculate my fat intake in imperial units?
Yes! Our calculator supports both metric (cm, kg) and imperial (ft, in, lbs) units. Simply switch between them using the toggle buttons at the top of the calculator.
What's an example calculation?
For a 30-year-old female, 165 cm tall, 65 kg, moderately active, maintaining weight: BMR ~1400, TDEE ~2170, target ~2170 kcal. Total fat ~72g (30%), saturated ~15g, monounsaturated ~32g, polyunsaturated ~23g, trans <2g.
