1. What is the Keto Diet?
The ketogenic diet is a high-fat, moderate-protein, and very low-carbohydrate eating plan. By drastically reducing carbohydrate intake, the body enters a metabolic state called ketosis, where it burns fat for energy instead of glucose.
Key Components:
- Fat: 70-75% of daily calories
- Protein: 20-25% of daily calories
- Carbohydrates: 5-10% of daily calories
2. How Does the Keto Diet Work?
Ketosis is the process where the liver converts fats into ketones, which become the primary energy source. Achieving ketosis requires strict adherence to macronutrient ratios.
Real-World Example:
Sarah, a 35-year-old teacher, experienced significant weight loss and increased mental clarity after adopting the keto diet. Her key to success was meal planning and tracking her macros diligently.
