How much fat should I eat per day?
Recommended fat intake: 20-35% of total calories for general health. Minimum: 0.3-0.4g per lb bodyweight for hormone production, vitamin absorption. Typical ranges: Standard diet = 50-80g (2,000 cal), Low-fat = 30-50g, Moderate = 50-70g, Higher-fat/Keto = 100-150g+. Calculate: Total calories × fat % ÷ 9 cal/g. Example: 2,000 cal at 30% fat = 600 cal ÷ 9 = 67g fat. Never go below 20% (hormone issues, nutrient deficiencies). Athletes may need 25-35% for energy and recovery.
What are healthy vs unhealthy fats?
Healthy fats (consume freely): Monounsaturated (olive oil, avocados, nuts) - reduces bad cholesterol, Polyunsaturated/Omega-3 (fish, flaxseed, walnuts) - anti-inflammatory, heart health, brain function. Saturated fats (moderate, <10% calories): Butter, coconut oil, red meat - okay in moderation, raises both good and bad cholesterol. Unhealthy fats (minimize): Trans fats (partially hydrogenated oils, fried foods, processed snacks) - raises bad cholesterol, lowers good cholesterol, increases heart disease risk. Avoid trans fats completely. Focus on unsaturated fats 70-80% of intake.
Do dietary fats make you gain fat?
No - total calories determine fat gain, not dietary fat specifically. Fat facts: 1g fat = 9 calories (vs 4 for carbs/protein), so calorie-dense but very satiating. Can gain fat on low-fat diet if calories too high, or lose fat on high-fat diet if in deficit. Fat benefits: Necessary for hormone production (testosterone, estrogen), absorbs vitamins A/D/E/K, provides energy, increases satiety (keeps you full), supports brain function. Key: Eat fat within calorie budget. Fat doesn't make you fat - excess calories do. Include healthy fats in every meal for satiety and nutrition.
How do I balance fat with protein and carbs?
Macro balance strategies: Standard balanced (carb-focused): 50% carbs, 20% protein, 30% fat - general population, active lifestyle. Moderate (balanced): 40% carbs, 30% protein, 30% fat - weight loss, muscle building. Low-carb: 20% carbs, 30% protein, 50% fat - appetite control, metabolic issues. Keto: 5% carbs, 25% protein, 70% fat - therapeutic, rapid fat loss. Set protein first (0.8-1g per lb), then split remaining calories between carbs and fat based on preference, activity level, and how you feel. Adjust based on results after 2-3 weeks.
What are the best sources of healthy fats?
Top fat sources: Omega-3 rich: Fatty fish (salmon, mackerel, sardines 2-3x/week), fish oil, flaxseed, chia seeds, walnuts. Monounsaturated: Extra virgin olive oil, avocados, almonds, cashews, peanut butter. Other healthy: Whole eggs (yolks), dark chocolate (70%+ cacao), cheese (moderate amounts), full-fat Greek yogurt. Cooking fats: Olive oil (low-medium heat), avocado oil (high heat), coconut oil (moderate). Portion control: Nuts/seeds = 1 oz (small handful), Oils = 1 tbsp, Avocado = 1/4-1/2, Nut butter = 1-2 tbsp. Easy to overconsume - measure portions.
