Fundamentals of Carnivore Nutrition
Carnivore nutrition primarily focuses on meat consumption and emphasizes a diet high in protein and fat while minimizing carbohydrates. Key components include the macronutrient breakdown, essential vitamins and minerals, the role of fats, and the understanding of carbohydrates within this dietary framework.
Macronutrient Breakdown
The carnivore diet relies heavily on animal-based proteins and fats. Protein is a building block for muscles, enzymes, and hormones, making it essential for overall health.
Quantities of macronutrients in a carnivore diet often include:
Protein: 25-35% of daily intake
Fat: 60-70%, primarily from animal sources
Carbohydrates: Less than 5%
Typical foods include:
Beef, lamb, and pork
Poultry and seafood
Animal fats like lard and tallow
Vitamins and Minerals
Despite the exclusion of plant sources, the carnivore diet can provide essential vitamins and minerals:
Vitamin B12: Crucial for neurological function, found in red meat and organ meats.
Iron: Beef and lamb are rich in heme iron, which is easily absorbed.
Zinc: Supports immune function and is abundant in beef and pork.
Vitamin D: Often found in fatty fish like salmon, supporting bone health.
Organ meats (e.g., liver) are nutrient-dense and can provide vitamins like A and E.
Role of Fats in Diet
Fats are a primary calorie source in a carnivore diet, promoting satiety and sustained energy levels. Types of fats include:
Saturated Fat: Found in beef, lamb, and pork, playing a role in maintaining hormonal health.
Monounsaturated Fats: Present in pork and some fatty fish, known for their heart health benefits.
Cholesterol: Vital for cellular function and hormone production, natural cholesterol from animal fats is different from processed types.
Butter, tallow, and lard are common fat sources supporting this dietary pattern.
Understanding Carbohydrates
The carnivore diet is virtually carbohydrate-free. Carbohydrates are reduced to promote:
Ketosis: A metabolic state where the body uses fat for fuel.
Low Insulin Levels: Helping regulate blood sugar and potentially reducing inflammation.
Reduction of Anti-Nutrients: Such as phytates and lectins found in plant foods, which some argue interfere with nutrient absorption.
Energy primarily comes from proteins and fats, making meal planning simple but focused on nutrient-dense animal products.
