GLP-1 medications have gained popularity for weight loss, but do they address why you eat the way you do?
Research shows that about 60% of people with obesity are emotional eaters, and women show higher numbers than men. People who practise restraint eating might respond better to the medication 15. However, emotional eaters might not see the same results.
People who overeat due to tempting food sights and smells lost more weight compared to those who ate because of negative emotions 17. Your eating behaviours play a vital role in determining whether the medication will work or not.
What are GLP-1 medications and how do they work?
GLP-1 medications work like a natural hormone your small intestine produces to control appetite and blood sugar levels. These medications started as type 2 diabetes treatments but have become popular for weight loss because they work on multiple body systems at once 21.
Semaglutide: Available as Ozempic and Rybelsus (for diabetes) and Wegovy (for weight loss) 22
Liraglutide: Marketed as Victoza (for diabetes) and Saxenda (for weight loss)
Tirzepatide: Sold as Mounjaro (for diabetes) and Zepbound (for weight loss) 3
Dulaglutide: Available as Trulicity (for diabetes) 21
Exenatide: Marketed as Byetta and Bydureon (for diabetes)
Tirzepatide stands out as a newer medication that targets both GLP-1 and GIP (gastric inhibitory polypeptide) receptors 23.
How they affect appetite and satiety
GLP-1 medications change your eating behaviour in several ways. They make food stay in your stomach longer, which helps you feel full longer 21. These medications also work directly on your brain's appetite control centres, particularly the hypothalamus. This makes you feel satisfied and less hungry 24.
Your pancreas releases more insulin when you take these medications. At the same time, they block glucagon (a hormone that raises blood sugar). This combination helps control your blood sugar levels - you end up eating less and feeling less hungry 6.
GLP-1 medications for weight loss: what the data shows
Research shows impressive weight loss results with GLP-1 medications. People taking semaglutide lost about 11% of their body weight over 24-68 weeks. Tirzepatide users lost even more - around 16% over 12-18 months 7. Liraglutide showed smaller changes with 4-5% weight reduction.
Results in real life without structured support programmes are nowhere near as dramatic - about 2% (around 6 pounds) after 72 weeks 8.
People without diabetes seem to lose more weight on these medications than those with diabetes. Non-diabetic patients saw their BMI drop by 2.96 kg/m² compared to 1.22 kg/m² in diabetic patients.
Understanding emotional eating and its impact on weight loss
Emotions significantly shape your eating habits, often working separately from physical hunger. You need to understand this relationship to think over any weight loss intervention, including GLP-1 medications.
What is emotional eating?
Emotional eating takes place when you eat because of your emotions rather than physical hunger 10.
Studies show that approximately 38% of adults eat emotionally in a given month, and 49% of these people do it weekly.
People reach for food when they feel stressed, bored, anxious, or lonely. Even positive emotions like joy or celebration can trigger this pattern 11.
Emotional hunger hits suddenly and makes you crave specific comfort foods (usually high in fat and sugar). You don't feel satisfied even after getting full 12. Physical hunger builds up slowly and you can satisfy it with different foods. Emotional hunger stems from psychological needs instead of what your body actually needs.
How emotional eating overrides hunger cues
Emotional eating disrupts fullness signals 13. Stress changes how well you notice these body cues 13. You don't respond to your body's need for food during emotional eating episodes. Instead, you look for comfort or distraction.
Your brain's reward system drives this override.
Eating high-calorie foods releases dopamine and opioids that briefly reduce stress responses and emotions 11. In spite of that, this relief doesn't last long. A problematic cycle forms where food becomes your way to cope rather than nourish.
Why emotional eating is common in obesity
Research consistently shows that emotional eating affects weight more than external factors like food availability and price 1. At least 40% of adults with obesity experience emotional eating. People with obesity often struggle more with handling negative emotions 13, so they use food to manage their feelings.
Emotional eating creates a harmful loop—eating lots of high-fat foods can make you feel bad, which leads to more comfort eating 1. Studies show that people who reported less emotional eating when starting weight loss programmes had better chances of losing 7% of their weight within six months 1.
How GLP-1 medications interact with emotional eating
The science behind GLP-1 medications shows a remarkable connection with how our brain responds to food. These medications do more than just reduce appetite—they change the way our brain processes food signals.
Brain response to food cues with GLP-1s
GLP-1 medications decrease neuronal responses to food pictures in brain regions that control appetite and reward, including the insula, amygdala, putamen, and orbitofrontal cortex 4. Medications like semaglutide don't directly cross the blood-brain barrier. They target circumventricular organs and bind to GLP-1 receptors in subcortical brain areas 14. This process can change our tastes and the way we eat.
Why emotional eaters may respond worse to GLP-1s
Research shows that people with higher emotional eating scores don't respond as well to GLP-1 treatments. When someone has higher baseline emotional eating scores, they show smaller GLP-1-induced reductions in brain responses to food cues in the amygdala and caudate nucleus 16.
Differences between emotional, external, and restraint eating
Emotional eating: People eat when emotions trigger them
External eating: Food cues in the environment trigger eating
Restraint eating: People consciously limit their food intake
GLP-1 medications work better for external eaters 17. Interestingly, people who practise restraint eating might get even better results from these treatments 15.
Short-term vs long-term effects on eating behaviour
GLP-1 medications reduce emotional eating at first 4, but we still need to determine their long-term psychological safety 18. The effects usually decrease between 52-104 weeks, though results remain better than the original baseline 14.
Can GLP-1 medications mask emotional eating habits?
GLP-1 medications reduce appetite, but they might mask emotional eating patterns instead of fixing them. This difference is significant to achieve long-term success in weight management.
Signs your emotional eating is still present
The medication won't stop you from eating due to stress, boredom, or negative emotions. Research shows that people who score higher on emotional eating tests don't respond as well to GLP-1 treatment 15. Your emotional eating probably still exists if you crave comfort foods even while taking the medication.
When weight loss plateaus despite medication
Most people hit weight loss plateaus with GLP-1 medications after about a year 5. Emotional eaters might reach these plateaus earlier and notice bigger slowdowns. Your body adapts to the medication and hormones that control weight start signalling your body to eat more 5.
The role of mindful eating and therapy
Mindful eating helps GLP-1 medications work better because it makes you more aware of your hunger signals. Cognitive behavioural therapy (CBT) makes a big impact - research shows patients who used both CBT and GLP-1 therapy lost more weight.
Key Takeaways
Understanding how GLP-1 medications interact with your eating patterns is crucial for achieving sustainable weight loss success.
Emotional eaters may experience reduced effectiveness - Studies show those with higher emotional eating scores exhibit less sensitivity to GLP-1 treatment effects compared to external eaters.
GLP-1s may mask rather than resolve underlying issues - These medications suppress appetite but don't address psychological triggers that drive emotional eating behaviours.
Combining therapy with medication yields better results - Patients using cognitive behavioural therapy alongside GLP-1 medications achieved significantly greater weight loss than medication alone.
Weight plateaus are common after one year - When medication effects diminish, unresolved emotional eating patterns often resurface, highlighting the need for comprehensive treatment approaches.
Mindful eating enhances medication effectiveness - Developing awareness of genuine hunger cues versus emotional cravings improves long-term weight management outcomes beyond pharmaceutical intervention.
Sustainable weight management requires addressing both the biological and psychological aspects of eating behaviour, making therapeutic support essential for lasting success.
