Hedonic hunger, eating behavior, and food reward and preferences 1 year after initial weight loss by diet or bariatric surgery
Authors' conclusion
Continued WL with bariatric surgery is paralleled by favorable changes in eating behavior and food reward and preferences. By contrast, controls experienced weight regain at 1Y follow-up and no changes in eating behavior. These striking differences are likely to be important in the long-term WL management of individuals with severe obesity.
Study context
- Population
- Patients scheduled for sleeve gastrectomy or Roux-en-Y gastric bypass, and controls
- Exposure
- Very low-energy diet plus bariatric surgery (SG or RYGB) vs very low-energy diet alone
- Outcome
- Changes in hedonic hunger, eating behavior, and food reward and preferences
- Follow-up
- 1-year follow-up
Main finding
As reported in the abstract
Hedonic hunger, eating behavior, and food reward · 1Y follow-up
- Decreases in emotional eating, hunger, disinhibition and food reward and increases in dietary restraint at 1Y in the bariatric-surgery groups only
Observational data: associations, not effects.
Further findings
Anthropometric variables and hedonic hunger · week 11
- Changes in anthropometric variables comparable across groups; hedonic hunger decreased overall
Body weight and fat mass · 1Y follow-up
- Bariatric-surgery groups continued to lose body weight and fat mass; weight regain in controls
