How Fat Intake Calculation Works - Medical Methodology

Our Fat Intake Calculation System uses AHA and WHO-verified nutrition formulas to provide accurate dietary recommendations and health optimization. Here's the complete technical methodology:

Standard Fat Calculation: Fat Grams = (Total Calories × Fat Percentage) ÷ 9. Since fat contains 9 calories per gram, this converts calorie percentages to actual gram amounts.

Saturated Fat Limit: Saturated Grams = (Total Calories × Saturated Limit %) ÷ 9. AHA recommends less than 5-6% for heart health, or less than 10% for general population.

TDEE Adjustment: For active individuals: Adjusted Calories = TDEE + Goal Adjustment (-500 for weight loss, 0 for maintenance, +250/+500 for gain).

Body Weight Method: Fat Grams = Body Weight (kg) × Grams per kg (0.5-1.5g based on goals).

Omega-3 Recommendations: 0.5-1.0g of combined EPA/DHA daily, or 1.1g for women/1.6g for men of ALA from plant sources.

AI Accuracy Enhancement: Our algorithms incorporate nutrition research data across different populations, health conditions, and dietary patterns to provide context-aware nutrition recommendations.

Nutrition Health Recommendations

Prioritize unsaturated fats - focus on monounsaturated and polyunsaturated fats from plants, nuts, seeds, and fish
Limit saturated fats - keep below 10% of total calories, ideally 5-6% for heart health
Avoid trans fats completely - check labels for "partially hydrogenated oils"
Include omega-3 sources - eat fatty fish 2-3 times weekly or supplement with fish oil
Balance fat with other macros - ensure adequate protein and complex carbohydrates
Consider cooking methods - use olive oil for low-heat cooking, avocado oil for high-heat
Read nutrition labels - check both total fat and saturated fat content
