ketogenic diets or very-low-carbohydrate ketogenic diets (VLCKD) have been in use long time ago as treatment for epilepsy and thereafter being become widely known as one of the most common methods for obesity treatment. Therefore, the aim of the present work was to determine the efficacy of ketogenic diet in weight reduction program and also point out the health outcome and blood biochemical changes during time of dieting.  A cross sectional study was carried out in 100 participants used ketogenic diet for their weight management from week 1 to approximately week 13 (29 male and 71 female) with those regard less their  body mass index but with ages 32.48 ± 2.27, respectively. Pre-design questionnaire was used and data were analyzed by paired Student's t test or chi-square accordingly. There were no significant changes in liver and renal function test, potassium ALT, AST, and blood creatinine except slightly decreased in sodium and increased acetone . The significant (P < 0.05) reduction in BMI (32.45 Kg/m2 to 27.4 Kg/m2), body weight (94.0 kg to 78.9  Kg) have been found. Furthermore, the total weight loss found  significant (19%) by which repsresent by 15 kg. Waist circumference and waist hip ratio were improved. The result also shown significant increased platelet count (P< 0.05). All lipid profile shown normal except slightly increased in LDL.The three significant top food were mostly consumed meat, chicken and eggs (P< 0.05). Although, there was some minor side effect reported by the participant include constipation, bad breathing  and lack of appetite and no other clinical signs reported. The more weight reduction has been shown in age groups 20-30 years old (20 kg) (P< 0.05) during time of dieting. No differences in weight reduction among male and female. The ketogenic diet lead to weight reduction, improvements in a number of risk markers included cardiovascular events and showed good compliance. Furthermore, ketogenic diet considered safe, an effective strategy for the management of overweight and obesity and promoting non-atherogenic lipid profiles, improving fasting blood glucose levels. Future research should include a larger sample size, a longer term use and a comparison with other ketogenic diets.
