The importance of chronotype, which reflects individual preferences in sleep timing and other behaviors, for obesity is mostly unknown. Morning types are more successful in long-term weight control than evening type chronotypes. Those with a sleep preference in the evening and a long sleep time have a higher rate of being overweight / obese than those with a morning preference and sufficient sleep time. Evening-type circadian preferences are indirectly related to food addiction. Individuals with the evening chronotype tend to have higher BMI and unhealthy eating habits.~Although a direct link between chronotype and obesity has not yet been demonstrated, based on the negative health consequences in evening chronotypes; In this study, it is assumed that success in obesity management will increase with well-timed circadian / sleep cycles, adequate sleep time and quality sleep in obese individuals with evening chronotype.~Therefore, in this study, it was aimed to examine the effect of circadian timing program created for obese individuals with evening chronotype on obesity management and sleep quality.~This study will be conducted in an experimental design, in a randomized controlled manner, in accordance with its purpose. The universe of the study will be obese individuals followed in Kocaeli University Hospital Obesity Outpatient Clinic. As a result of the power analysis performed to determine the sample size, the number of individuals in each group was determined as n = 18. The sample of the study will be 36 individuals in total. Participants will be selected to the intervention and control groups by simple randomization method.
