The keto diet, low in carbs and high in fats, promotes weight loss, stabilizes blood sugar, enhances cognitive function, and reduces inflammation. Key tips for success include calculating macros, choosing healthy fats, monitoring carb intake, staying hydrated, and being patient during the initial adaptation. Consult a healthcare professional, address nutrient deficiencies, be prepared for temporary symptoms ("keto flu"), and consider long-term sustainability when starting the keto diet. It offers significant health benefits but requires careful consideration and professional guidance.
