Understanding the Core Principles of Paleo
The paleo diet, or "caveman diet," is based on the idea that human bodies are best adapted to the diet of our Paleolithic ancestors. This dietary approach prioritizes whole foods and excludes processed items, sugars, and products from the agricultural era. Instead of calorie counting, the focus is on nutrient density and consuming minimally processed foods.
Key Principles of a Paleo Meal Plan
- Prioritize whole foods: Emphasize fresh, natural ingredients.
- Choose high-quality proteins: Include lean meats, poultry, and wild-caught fish.
- Incorporate healthy fats: Add avocados, nuts, seeds, olive, and coconut oil.
- Eat plenty of fruits and vegetables: These provide essential nutrients and fiber.
- Avoid grains and legumes: These are typically excluded due to their absence in the ancestral diet.
- Eliminate refined sugars and processed foods: Cut out artificial additives and excess sugar.
