Background: The growing prevalence of obesity/overweight is raising concerns worldwide. Many factors have been addressed to be
associated with the epidemiology of obesity/overweight. Therefore, the present study aimed to measure the association between
nutritional habits and obesity/overweight in Hai'l Region Saudi Arabia. Methodology: In this cross-sectional study, 750 Saudi
volunteers were recruited during the period from May to October 2020. The study was planned to assess the effects of the
nutritional habit on body weight status. Results: The overall prevalence of overweight/obesity was 490/732(67%), including
281/732(38.4%) overweight, 134/732(18.3%) obese, and 75/732(10.2%) morbid obesity. Conclusion: Obesity/overweight is prevalent
in Northern Saudi Arabia, which might be attributed to nutritional habits. High frequency of meats, dairy products, and sugarsweetened
drinks are factors influencing the prevalence rates of obesity/overweight.
