The ketogenic diet (keto diet) emphasizes high fat and protein intake while significantly reducing carbohydrate consumption to enable the body to generate energy from ketones instead of glucose. This diet provides numerous health benefits, including improved cholesterol levels, reduced risk of diabetes, and lower blood pressure, while offering a diverse food selection. To successfully adopt the keto diet, it is essential to avoid high-carb foods, maintain hydration, manage salt intake, and recognize common pitfalls to ensure effective weight loss and overall health improvement.
