Understanding the Carnivore Diet
The carnivore diet revolves around consuming only animal products while eliminating plant-based foods. This approach focuses on high protein and fat intake, with minimal to no carbohydrates.
Definition and Principles
The carnivore diet is a restrictive eating plan that includes only animal-derived foods. Meat, fish, eggs, and some dairy products form the core of this diet.
Plant-based foods, including fruits, vegetables, grains, and legumes, are excluded entirely. This diet aims to mimic the eating patterns of our carnivorous ancestors.
Proponents argue that humans are adapted to thrive on animal products alone. The diet emphasizes nutrient-dense foods and seeks to eliminate potential plant-based irritants or antinutrients.
Macronutrient Composition
The carnivore diet’s macronutrient profile is unique, with a heavy emphasis on protein and fat.
Protein typically accounts for 20-35% of caloric intake. It supports muscle growth, repair, and various bodily functions.
Fat makes up 65-80% of calories. It serves as the primary energy source, replacing carbohydrates.
Carbohydrates are nearly absent, usually less than 5% of total calories. This can induce a state of ketosis, where the body burns fat for fuel.
| Macronutrient | Percentage of Calories |
|---|---|
| Protein | 20-35% |
| Fat | 65-80% |
| Carbohydrates | <5% |
