Background: Although various studies have examined the short-term effects of a ketogenic diet in reducing weight in obese patients, its long-term effects on various physical and biochemical parameters are not known. The body weight, body mass index, total cholesterol, low density lipoprotein LDL cholesterol, high density lipoprotein HDL cholesterol, triglycerides, fasting blood sugar, urea and creatinine levels were determined before and after the administration of the ketogenic diet.
