Ketogenic Diet Overview

The ketogenic diet was initially developed in the 1920s by Dr. Russell Wilder at the Mayo Clinic for the treatment of epilepsy. The diet has gained renewed attention recently for its potential benefits in weight management and metabolic health. The ketogenic diet, a high-fat, low-carbohydrate dietary approach, has gained attention for its potential health benefits. This review explores the ketogenic diet’s impact on various aspects of health, including metabolic health, weight management, and neurological function. By analysing current research findings, this article provides comprehensive insights into the potential benefits and considerations associated with this diet. Additionally, this review addresses the practical implications and challenges in implementing and sustaining a ketogenic dietary pattern.


The keto diet has emerged as a dietary strategy that involves consuming high amounts of healthy fats, moderate protein, and minimal carbohydrates. This metabolic state, ketosis, has been associated with various potential health benefits, including weight loss, improved insulin sensitivity, and enhanced cognitive function. As interest in the keto diet grows, it is essential to critically evaluate the scientific evidence supporting its efficacy and implications for overall health and well-being.

Metabolic Health and Weight Management

Numerous studies have investigated the effects of the ketogenic diet on metabolic health, particularly insulin sensitivity, blood lipid profiles, and markers of inflammation. Current evidence suggests that the ketogenic diet may contribute to improved glycemic control, reduced triglyceride levels, and favourable alterations in cholesterol metabolism. Furthermore, the metabolic state induced by ketosis has been linked to enhanced fat-burning and potential benefits for weight management and body composition.

Neurological Function and Cognitive Health

An emerging area of interest is the potential impact of the keto diet on neurological function and cognitive health. Research indicates that ketone bodies produced during ketosis may serve as an alternative energy source for the brain, potentially exerting neuroprotective effects and supporting cognitive function. Furthermore, the ketogenic diet has shown promise in various neurological conditions, including epilepsy, Alzheimer’s disease, and Parkinson’s disease, prompting further investigation into its therapeutic potential for neurodegenerative disorders.

Practical Considerations and Challenges

While the ketogenic diet holds promise for health and well-being, its adoption and maintenance pose practical challenges for individuals. These challenges include navigating dietary restrictions, ensuring adequate nutrient intake, and managing potential side effects associated with the transition to a ketogenic metabolic state. Addressing these considerations and providing evidence-based guidance for individuals considering or currently following a ketogenic diet is imperative.


The scientific evidence surrounding the ketogenic diet highlights its potential impact on metabolic health, weight management, and neurological function. While further research is warranted to elucidate its long-term implications and optimal application, the ketogenic diet presents a compelling dietary strategy for individuals seeking to optimise their health and well-being. By addressing practical considerations and challenges, healthcare professionals can offer informed guidance to support individuals in adopting and sustaining a ketogenic dietary pattern.
