Therefore, keto diet, short for ketogenic, involves eating a high amount of fat, a moderate amount of protein and very few carbs. This research paper aims to know about the effect of a ketogenic diet on our body, to know about the mechanism of the ketogenic diet in treating neurodegenerative disorders and to know about the mechanism of the ketogenic diet in reducing the weight of our body. Also, the objective was to investigate the ketogenic diet stimulates ketogenesis which treats certain neurodegenerative disorders. Although this is high fats containing food it is beneficial for our body in certain conditions. It is also useful in the conditions in which the brain requires a low level of glu- cose so the brain starts utilizing ketone bodies. As the intake of carbohydrates is lowered so it is also used to reduce the weight of the body. In this research, the qualitative methodology has been adopted which refers to secondary sources of data. In this project, I used a variety of research that has also been undertaken by numerous researchers including dietitians who tend to sup- port the positive benefits of using ketogenic diets to manage losing weight as well as other health problems that could result from overweight. Also, we used a table to show the difference between studies. Finally, it is important to note that the ketogenic-diet has created debate, partially although traditional dietary education has, for years, illustrated the adverse effects of high overall including trans-fat intake.

Introduction The keto-diet which is also known as the ketogenic diet is a specific type of diet in which low carbohydrates are taken but the content of fats and proteins is kept high in food. So the body’s weight is reduced with high fats. This way of dieting How to cite this paper: Alharbi, A. and Al-Sowayan, N.S. (2020) The Effect of Ketogenic-Diet on Health.
