About this study
Official title: Effects of an Intuitive Eating Intervention on Body Weight, Body Image, and Eating Attitudes in Women Who Regained Weight After Bariatric Surgery
This study evaluated the validity and reliability of the Turkish version of the Intuitive Eating Scale-2 (IES-2) in individuals who had undergone bariatric surgery and examined the effects of a 6-week online intuitive eating intervention. The study consisted of two stages. In the first stage, 297 adults aged 18-65 years who had undergone bariatric surgery were included to evaluate the psychometric properties of the Turkish IES-2. Exploratory and confirmatory factor analyses, internal consistency, and test-retest reliability were assessed. In the second stage, a 6-week prospective, non-randomized controlled intervention study was conducted among 60 individuals who had undergone bariatric surgery at least two years previously and had regained at least 20% of their maximum weight loss. Participants received either an online intuitive eating intervention or standard nutritional counseling. Outcomes included intuitive eating behaviors, eating attitudes, body perception, body weight, and body mass index (BMI). The Turkish IES-2 demonstrated a valid and reliable three-factor, 17-item structure. The intervention was associated with improvements in intuitive eating behaviors and reductions in eating attitude scores, while no significant changes were observed in body weight or BMI. The findings suggest that an online intuitive eating intervention may improve intuitive eating behaviors and some eating attitudes among individuals who regain weight after bariatric surgery.
Read the detailed description
Bariatric surgery is an effective treatment for severe obesity; however, weight regain may occur in a proportion of individuals following surgery and may be accompanied by difficulties in eating behaviors, body perception, and eating attitudes. Intuitive eating is an approach that emphasizes responding to internal hunger and satiety cues, reducing reliance on restrictive eating rules, and developing a more adaptive relationship with food. This approach may be relevant to individuals who experience weight regain after bariatric surgery.
This study was designed in two stages. The first stage focused on evaluating the psychometric properties of the Turkish version of the Intuitive Eating Scale-2 (IES-2) among individuals who had undergone bariatric surgery. The second stage investigated whether a 6-week online intuitive eating intervention could improve intuitive eating behaviors and eating-related outcomes in individuals who had experienced weight regain following bariatric surgery.
The intervention was based on the principles of intuitive eating and was delivered online over six weeks. The intervention aimed to support participants in recognizing and responding to internal hunger and satiety cues, reducing rigid dietary rules, developing a more positive relationship with food and body, and increasing awareness of eating-related behaviors and emotions. The intervention group was compared with participants receiving standard nutritional counseling.
The study was conducted to provide evidence regarding the applicability of intuitive eating as a behavioral approach for individuals experiencing weight regain after bariatric surgery and to contribute to the assessment of intuitive eating in this population using a culturally appropriate measurement instrument.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Intuitive Eating InterventionBehavioural
A 6-week intuitive eating intervention consisting of weekly online group sessions, individual intuitive eating counseling sessions, and supportive materials delivered through an online messaging platform. The intervention was adapted for individuals who had undergone bariatric surgery and addressed intuitive eating principles, hunger and satiety awareness, eating behaviors, emotional eating, body respect, self-compassion, mindful eating, joyful movement, and gentle nutrition.
Standard Nutritional CounselingBehavioural
Weekly one-on-one nutrition counseling provided by an experienced bariatric dietitian for 6 weeks. Standard nutritional recommendations for weight regain following bariatric surgery were provided throughout the follow-up period.
| Study group | Role | What they receive |
|---|---|---|
| Intuitive Eating Intervention | Experimental | Participants in this arm received a 6-week intuitive eating intervention designed to improve intuitive eating behaviors and eating-related attitudes following weight regain after bariatric surgery. The intervention focused on recognizing internal hunger and satiety cues, reducing rigid dietary rules, increasing awareness of eating behaviors and emotions, and developing a more adaptive relationship with food and body. Receives: Behavioral: Intuitive Eating Intervention |
| Standard Nutritional Counseling | Active comparator | Participants in this arm received standard nutritional counseling during the study period. The counseling represented the usual nutritional guidance provided to individuals who had undergone bariatric surgery and was used as the comparison condition for the online intuitive eating intervention. Receives: Behavioral: Standard Nutritional Counseling |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change in Intuitive Eating Score
Change in total score of the Turkish 17-item Intuitive Eating Scale for Bariatric Surgery (IES-BS) from baseline to post-intervention.
Measured: Baseline and immediately after the 6-week intervention
Secondary outcomes (3)
Change in Eating Attitudes
Change in the total score of the Eating Attitudes Test-26 (EAT-26) from baseline to post-intervention. Higher scores indicate more problematic eating attitudes.
Measured: Baseline and immediately after the 6-week intervention
Change in Body Image
Change in body image/body perception score from baseline to post-intervention, assessed using Body Perception Scale .
Measured: Baseline and immediately after the 6-week intervention
Change in Body Mass Index
Change in body mass index (BMI), calculated as body weight in kilograms divided by height in meters squared (kg/m²), from baseline to post-intervention.
Measured: Baseline and immediately after the 6-week intervention
