The ketogenic diet emphasizes a very low carbohydrate intake (5–10% of calories) and high fat consumption (60–80% of total calories), promoting fat loss and potential health benefits but may not be suitable for everyone, particularly those with certain health conditions. Meal plans should focus on keto-friendly foods like meats, eggs, full-fat dairy, and low-carb vegetables, while avoiding high-carb items such as grains, sugars, and starchy vegetables. It's advisable to consult a healthcare professional before starting the diet to ensure safety and effectiveness.
