About

There is increasing evidence of the effects of the time-restricted diet model based on the daily intake of energy within a period of 8-12 hours on body weight control and metabolic parameters. There is no study on the potential effects of this nutritional model, which is thought to be an effective strategy in struggling with metabolic syndrome, on individuals' eating behavior and impulsivity levels. This study, which aims to evaluate the effects of time- restricted diet strategy on food intake, eating attitude and behavior and impulsivity level in adults, is a mixed method, randomized controlled intervention study. Thirty adult individuals between the ages of 18-65 will be included in this study, which will be carried out between 31.05.2021-31.12.2021 in Istinye University. Participants will be divided into 2 groups: the intervention group (n = 15) will apply a time-restricted nutrition model for 4 weeks, and no intervention will be applied to the control group (n = 15). Participants' food intake before and after the intervention period will be evaluated with a 3-day food intake record, their eating attitudes will be evaluated with the Eating Attitude Test (EAT-26), their impulsivity levels will be evaluated with the Barratt Impulsiveness Scale-Short Form (BIS-11-SF) and Go / NoGo test, and their eating behaviors will be evaluated with the Three Factor Eating Questionnaire (TFEQ-R21). At the end of the research, all individuals in the intervention group will be interviewed in depth and their experiences regarding the process will be recorded. IBM SPSS 22 program will be used in the analysis of all quantitative data, and the MAXQDA-12 program will be used in the analysis of qualitative data. The data obtained from this research will clear up the applicability of the time- restricted diet model and its effects on eating behaviors of adults.
