Japanese study shows Ozempic works best for external eaters but less effectively for emotional eaters, highlighting need for psychological support alongside medication.

New Study Reveals Ozempic's Effectiveness Depends on Eating Behavior
A groundbreaking Japanese study has revealed that the effectiveness of weight-loss medications like Ozempic varies significantly depending on an individual's eating behavior patterns. The research, conducted by scientists from Kyoto University, followed 92 patients with type 2 diabetes for one year as they used GLP-1 receptor agonists.
External Eaters vs. Emotional Eaters
The study found that patients who primarily eat in response to external cues—such as the sight or smell of food—experienced the most dramatic results. These individuals lost more weight and showed greater improvements in blood sugar levels compared to emotional eaters who consume food to cope with stress, sadness, or frustration.
"GLP-1 receptor agonists are effective for people who overeat due to external stimuli, but when emotional eating is the main cause, there's less effect from the weight-loss medication," explained lead researcher Daisuke Yabe from Kyoto University.
Temporary Behavioral Changes
Researchers observed that after three months of treatment, participants showed reduced emotional and external eating patterns and increased controlled eating. However, this positive behavioral change proved temporary, with most participants returning to their original eating patterns after one year.
Takehiro Kato, another researcher involved in the study, noted: "Psychological factors play a major role here. Medications don't have direct influence on them. People with strong emotional eating tendencies often need additional psychological or behavioral support to overcome this."
Significant Health Benefits Still Achieved
Despite the behavioral differences, the treatment provided substantial health benefits across all participants. Patients lost significant weight, reduced their body fat percentage, improved cholesterol levels, and maintained stable muscle mass—a crucial factor for long-term health.
The study, published in Frontiers in Clinical Diabetes and Healthcare, emphasizes that medications like Ozempic work best when combined with healthy habits and psychological insight into eating behaviors.
