A ketogenic diet (KD), more commonly called a "keto" diet, is a dietary regime that focuses on reducing carbohydrates and replacing them with healthy fats. It has proven to improve health and has resurfaced as a trendy weight loss method. Keto, in simple terms, works by mimicking starvation and forcing the body to utilize and deplete fat as its core energy source instead of its usual source of glucose (sugar). More technically, it gives ignition to a process called 'ketosis'. Ketosis is the process of generation of ketone bodies when the liver metabolizes fat. There are several versions of this diet, each of which addresses slightly variable issues as well as hones unique requirements. Individuals will require a unique combination of fat, carbohydrates, and protein depending on their genetic and physical makeup. The advantages and hazards of using the KD to manage obesity are examined in this review of the literature.
