What Is the Ketogenic Diet?
The ketogenic diet is a high‑fat, moderate‑protein, very‑low‑carb eating plan designed to shift your body into a fat-burning state called ketosis. This metabolic state can support weight loss, mental clarity, and better energy levels.
Key Benefits of the Keto Diet
Rapid Weight Loss
By drastically reducing carbohydrates and increasing healthy fats, your body burns stored fat for energy—leading to fast, sustainable weight loss.
Improved Mental Focus
Many beginners report sharper focus and fewer “brain fog” episodes once in ketosis.
Blood Sugar and Insulin Control
Keto helps stabilize blood glucose and reduce insulin resistance—ideal for those managing pre‑diabetes or type 2 diabetes.
