Introduction: Ketogenic diet was first approached diet in treatment of epilepsy in children, later on, many studies showed its positive effect on adults who have chronic diseases and obesity. The main aim of the diet is to allow the body to reach the state of ketosis by generating energy from fat rather than glucose, and this happen by lowering the carbohydrates, adding moderate protein and high fat, thus letting the body burn fat for fuel. Since more than 50 years studies linked consumption of saturated fat with cardio-metabolic disease risk and obesity, and nowadays many studies have shown a positive impact of consumption of saturated fat. Therefore, this is a study to determine the prevalence of Saudi adult with chronic disease who follow a ketogenic diet. Methods: This was an observational cross-sectional study based on web-survey questionnaires developed by developed originally by author with high confidence level. The sample size was 479 estimated using the Qualtrics calculator with a confidence level of 95% and a margin of error of 5%. The questionnaire is divided into four categories. We started the questioner with demographic factors including age, nationality, dental degree date and in which country, work setting and cariology course attendance. 2nd it was about 3 clinical scenarios. Data were collected using Google forms and prepared for analysis using Microsoft Excel. Statistical analysis was performed using the SPSS software. Results: The total number of the current study participants was 464, the highest percentage (33.90%) were in the age group of 40-50 years old, 44.80% were in the weight range of 61-80 kg, while 11.90% have a weight of >100 kg, and half (50%) of the participants have a height range of 151-160 cm. Most (71%) of the participants have a college educational level, and 44.30% were employees. The prevalence of hypercholesterolemia and diabetes among the respondents was 23.70%, and 2.50%, respectively. The overall prevalence of metabolic syndrome was 2.30%. Almost half (50.10%) of the participants reported having obesity, and 19.10% were hypertensive. Conclusion: Ketogenic diet in this review showed a positive results within the utilization in chronic illnesses and obesity. In any case, The long-term hazard related with adverse impacts is unknown; therefore, advance studies may be valuable. Future randomized clinical trials are required to affirm the viability of the ketogenic diet in different sorts of adults’ chronic illness and to supply advance data on a few uncertain commonsense issues, i.e., how long the ketogenic diet ought to be proceeded.

Background: Overuse of electronic gadgets has been highlighted as a possible preventable risk factor for eyesight loss. Excessive use of electronic gadgets, on the other hand, has been linked to vision impairment in a variety of ways. Methods: This was an analytical cross-sectional study to spotlight on the relationship between visual impairment and addiction to electronic devices use. The study's goal was to see if there was a link between Saudis' vision impairment and their addiction to using electronic devices, this is the suitable design for this research. The study was carried out among Saudi population. Data were collected from general population using questionnaire during the period from 22 August to 22 November 2020. Results: The study included the participation of 344 participants from both genders and different age groups in the Kingdom of Saudi Arabia. There were 211 female participants (61.3%) and 133 males (38.7%) took place in this study. The most prevalent age group was under the age of 25 years (n= 111, 32.3%) followed by the age group 25-35 (n= 104, 30.2%) while the least frequent age group was above 45 years (n= 54, 15.7%). On asking the participants whether they think that they have vision impairment or not, their answers were as follows: yes (n= 156, 45.3%), no (n= 131, 38.1) and maybe (n= 57, 16.6%). Due to the use electronic devices, there were 107 participants complained of headache (31.1%). And this was significantly related to the number of hours spent by study participants using electronic devices (P= 0.002) as well as significant for female gender more than male gender (P= 0.03). Conclusion: The study showed statistically significant relationship between the number of hours spent on using electronic devices and visual impairment among study participants especially among female population more than male population. There is a need for awareness campaigns to increase health awareness among population to cut down the use of electronic devices.
