The ketogenic diet, or keto for short, is a high-fat, low-carbohydrate diet that aims to put the body into a state of ketosis, in which it burns fat for energy instead of glucose. A typical keto meal consists of high-fat foods such as meat, fish, eggs, cheese, and nuts, along with low-carbohydrate vegetables like leafy greens and cruciferous vegetables.

While the keto diet has been shown to be effective for weight loss and improving certain health conditions such as epilepsy, it is important to approach this diet with caution and under the guidance of a healthcare professional, as it can also have negative effects on some individuals. It is also important to ensure that adequate nutrient intake is maintained, particularly for vitamins and minerals that may be limited on a high-fat diet.
