New research suggests that weight loss medications such as Ozempic and Wegovy may not work as well for individuals who struggle with emotional eating.

These drugs, classified as GLP-1 receptor agonists, are designed to reduce appetite and calorie intake. While they tend to be effective for those who overeat in response to external cues—like how food looks or smells—they appear to be less beneficial for people whose eating habits are driven by emotions like stress, sadness, or anxiety.

The study, published on September 16 in Frontiers in Clinical Diabetes and Healthcare, urges healthcare professionals to carefully assess a patient’s eating behaviors before prescribing GLP-1 medications or considering surgical interventions like bariatric surgery.

“These medications are most effective for individuals whose overeating is triggered by environmental factors,” said Dr. Daisuke Yabe, the study’s senior author and a professor of medicine at Kyoto University. “Their benefits are limited when emotional eating is the root issue.”

Other experts echo that sentiment, emphasizing that emotional and psychological factors must be addressed early in the treatment process.

“Successful weight loss isn’t just about appetite control—it’s about understanding why someone eats,” said Dr. Mir Ali, a bariatric surgeon at MemorialCare Surgical Weight Loss Center in California.

Dr. Zhaoping Li, a professor of clinical medicine at UCLA, agreed, saying, “Every patient has unique challenges and motivations. Treatment needs to be tailored accordingly.”

Kristin Kirkpatrick, a registered dietitian at the Cleveland Clinic, said the study, though relatively small, sheds light on a critical issue.

“The takeaway is clear,” she said. “Education, emotional support, and behavior change strategies should go hand-in-hand with medication, especially as patients prepare to stop taking it.”

Study Details: How Eating Behaviors Influence Drug Results

Researchers followed 92 adults in Japan diagnosed with type 2 diabetes as they began taking GLP-1 weight loss medications. Participants were evaluated at the beginning, after three months, and again after one year. Data collected included weight, body composition, blood markers, and dietary habits.

Participants were divided into three categories based on their eating behavior:

• Emotional Eating – Eating triggered by negative emotions

• External Eating – Eating in response to food-related sensory cues

• Restrained Eating – Deliberately restricting food to lose weight

Across all groups, participants experienced some weight loss and improvements in cholesterol levels. However, the most consistent and meaningful results came from the external eating group. Those in the emotional and restrained eating groups were more likely to revert to old habits by the end of the study.

Dr. Li emphasized that eating is often emotionally driven. “People eat for reasons that go beyond hunger,” she said. “They eat to cope with emotions like stress or boredom.”

Dr. Ali added that recognizing emotional eating can be difficult, which is why mental health professionals should be involved in obesity care. “If emotional needs are the real issue, reducing appetite won’t solve the underlying problem,” he said.

Tackling Emotional Eating Patterns

Kirkpatrick explained that emotional eating often stems from using food to manage emotional discomfort.

“People reach for food as a form of relief,” she said. “But the choices made in those moments—usually ultra-processed and low in nutrients—only offer short-term comfort, followed by a crash and the urge to eat again. It’s a cycle.”

For external eaters, the issue revolves more around reacting to sensory triggers.

“Some people will drive out of their way to get fast food just because the thought crossed their mind,” Kirkpatrick said. “Others may overeat simply from seeing or smelling food. Helping people identify and manage those cues is key.”

With restrained eaters, the focus shifts to breaking restrictive patterns and developing a more balanced approach to eating.

“When people overly restrict food, they often end up bingeing later and feeling guilty,” Kirkpatrick explained. “Instead of labeling food as ‘bad,’ I help clients understand that food choices can nourish body, mind, and soul. It’s about balance, not perfection.”

Obesity in the U.S. and Health Risks

According to the Centers for Disease Control and Prevention (CDC), around 40% of U.S. adults are classified as obese. Rates are comparable between men and women, with the highest prevalence among individuals aged 40 to 59.

Obesity is typically defined as a body mass index (BMI) of 30 or higher or a waist circumference above 40 inches for men and 35 inches for women. It’s associated with a higher risk of numerous health problems, including:

• Heart disease

• Type 2 diabetes

• High blood pressure

• Gallbladder disease

• Fatty liver disease

• Sleep apnea

GLP-1 medications like Ozempic and Wegovy (semaglutide), as well as Mounjaro and Zepbound (tirzepatide), are increasingly prescribed to help manage obesity and type 2 diabetes. These drugs are typically used alongside healthy lifestyle changes, including improved diet, regular exercise, and better sleep routines.

Kirkpatrick said many of her patients report a noticeable reduction in food-related thoughts while taking these medications.

“They describe it as a mental relief from constant food cravings,” she said. “But they’re also concerned about what happens when they stop the medication—will old habits come back?”

Conclusion: Long-Term Success Requires More Than Medication

While medications like Ozempic and Wegovy offer powerful tools for weight loss, they aren’t a complete solution—especially for people whose eating behaviors are rooted in emotional coping.

Experts stress that identifying the why behind eating habits is crucial for long-term results. Lasting success is more likely when medication is combined with psychological support, behavior therapy, and sustainable lifestyle changes.

Ultimately, the most effective weight loss approach addresses both physical and emotional health—fostering a healthy relationship with food, body, and mind.
