Spending the Holidays With GLP-1 Receptor Agonists: 5 Things to Know

Beverly Tchang, MD

As an endocrinologist, I treat many patients who have diabetes, obesity, or both. Antiobesity medications, particularly the class of glucagon-like peptide-1 receptor agonists (GLP-1 RAs), are our first support tools when nutrition and physical activity aren't enough. With the holidays upon us, here are five tips that I often share with my patients who are on GLP-1 RAs and similar medications.

1. Be mindful of fullness cues. 

GLP-1 RAs increase satiety; they help patients feel fuller sooner within a meal and longer in between meals. This means consuming the "usual" at a holiday gathering makes them feel as if they ate too much, and often this will result in more side effects, such as nausea and reflux.

Patient tip: A good rule of thumb is to anticipate feeling full with half of your usual portion. Start with half a plate and reassess your hunger level after finishing.

2. Distinguish between hunger and "food noise."

Ask your patients, "Do you ever find yourself eating even when you're not hungry?" Many people eat because of emotions (eg, stress, anxiety, happiness), social situations, or cultural expectations. This type of food consumption is what scientists call "hedonic food intake" and may be driven by the "food noise" that patients describe as persistent thoughts about food in the absence of physiologic hunger. Semaglutide (Ozempic, Wegovy) has been found to reduce cravings, though other research has shown that emotional eating may blunt the effect of GLP-1 RAs.

Patient tip: Recognize when you might be seeking food for reasons other than hunger, and try a different way to address the cue (eg, chat with a friend or family member, go for a walk).

3. Be careful with alcohol.

GLP-1 RAs are being researched as potential treatments for alcohol use disorder. Many patients report less interest in alcohol and a lower tolerance to alcohol when they are taking a GLP-1 RA. Additionally, GLP-1 RAs may be a risk factor for pancreatitis, which can be caused by consuming too much alcohol.

Patient tip: The standard recommendation remains true: If drinking alcohol, limit to one to two servings per day, but also know that reduced intake or interest is normal when taking a GLP-1 RA.

4. Be aware of sickness vs side effects.

With holiday travel and the winter season, it is common for people to catch a cold or a stomach bug. Symptoms of common illnesses might include fatigue, loss of appetite, or diarrhea. These symptoms overlap with side effects of antiobesity medications like semaglutide and tirzepatide.

Patient tip: If you are experiencing constitutional or gastrointestinal symptoms due to illness, speak with your board-certified obesity medicine doctor, who may recommend a temporary medication adjustment to avoid excess side effects.

5. Stay strong against weight stigma.

The holiday season can be a stressful time, especially as patients are reconnecting with people who have not been a part of their health or weight loss journey. Unfortunately, weight bias and weight stigma remain rampant. Many people don't understand the biology of obesity and refuse to accept the necessity of medical treatment. They may be surrounded by opinions, often louder and less informed.

Patient tip: Remember that obesity is a medical disease. Tell your nosy cousin that it's a private health matter and that your decisions are your own.
