The ketogenic diet has revolutionized weight loss and health optimization. This comprehensive guide covers everything you need to know about starting and succeeding with keto, from basic principles to advanced strategies.
What is the Keto Diet?
The ketogenic diet is a very low-carb, high-fat eating plan that forces your body into ketosis - a metabolic state where you burn fat for fuel instead of carbohydrates. Typically, keto involves eating 70-80% fat, 15-25% protein, and 5-10% carbohydrates.
How Keto Works
When you drastically reduce carbs, your liver converts fat into ketones, which become your body's primary energy source. This metabolic shift can lead to rapid weight loss, improved mental clarity, and stable energy levels.
