    Can artificial intelligence replace dietitians? A conversation with ChatGPT
    (Toros Üniversitesi, 8 Temmuz 2024) Ülker, Mutlu Tuçe; Güner, Elif
    In this study, an interview was conducted with Generative Pre-Train (ChatGPT) in order to determine whether artificial intelligence can replace dietitians and its potential contributions to the field of Nutrition and Dietetics. Qualitative research method was used in the study and data was obtained using interview technique. The study includes 6 questions asked to version 3.5. of ChatGPT. Based on the answers given to the questions, ChatGPT has shown that it can benefit dietitians in providing basic nutritional information and helping to create nutrition plans. Nonetheless, artificial intelligence cannot fulfill the official duties and responsibilities of dietitians and cannot create disease- and individual-specific nutrition programs. ChatGPT, which is reported to provide theoretical resources as a contribution to Nutrition and Dietetics education, lacks personal experience and practical skills. Although ChatGPT contributes to dietitians, educators, and students in the field of nutrition and dietetics in different dimensions, it cannot replace dietitians. More research on the use of generative language models developed by artificial intelligence is necessary.

    Time-restricted feeding can increase food-related impulsivity: a randomized controlled trial
    (Taylor and Francis Ltd., 2025) Güner, Elif; Aktaç, Şule
    Objectives: Although an increasing number of studies show that time-restricted feeding may improve metabolic health, studies examining the behavioral effects of this eating pattern are limited. This study examined the effect of time-restricted feeding on impulsivity in adults. Methods: Thirty adults aged 25–41 years participated in this randomized controlled trial. The intervention group followed time-restricted feeding for 4 weeks and there was no energy restriction in the intervention group (n = 15) or control group (n = 15). Impulsivity was assessed before and after the intervention with the Barratt Impulsiveness Scale and the Go/NoGo task. Results: The compliance rate (the percentage of days when participants had a feeding time of ≤ 8 hours/day) of the intervention group to the time-restricted feeding pattern was 92.38 ± 4.24%. The Barratt Impulsiveness Scale-11 total score of the intervention group increased from 55.53 ± 6.37 to 59.47 ± 7.67 (p = 0.02). During the Go/NoGo task, an indicator of inhibitory control, the reaction time to food and non-food stimuli was significantly shortened in the intervention group (respectively; p = 0.009, p = 0.01). In the control group, no significant change was detected in impulsivity determined by the BIS-11 or Go/NoGo task. Discussion: This study showed that although time-restricted feeding may reduce body weight, it can lead to increased impulsivity and impaired inhibitory control.
