Introduction to Weight Loss Injections During Christmas
Mounjaro and Wegovy are popular weight loss drugs that can lead to impressive weight loss results. In clinical trials, Wegovy helped people lose an average 15.8% of their body weight over 68 weeks. Mounjaro was even more effective, helping people lose an average 22.5% of their starting body weight over 72 weeks when taken at the highest dose.
However, Wegovy and Mounjaro are only effective if you're willing to make changes to your diet and exercise regimes. That can be harder than ever at Christmas as it can be tempting to partake in the festive season indulgence. With so much of the holiday revolving around eating and drinking, it can be hard to stay on track. You don't have to have a very strict diet and can allow yourself a few treats, it is all about the balance.
Of course, you still want to enjoy the Christmas period, but taking things too far can derail your weight loss efforts so far.
Let's talk about how you can balance enjoying festive food with your weight loss progress and address some of the myths around Christmas and weight loss medications.
How Do Weight Loss Injections Work Over the Festive Period?
What are Weight Loss Injections and Their Benefits?
Mounjaro and Wegovy belong to a family known as GLP-1 receptor agonists. This means they work by mimicking a hormone called glucagon-like peptide 1 (GLP-1) that's naturally found in the body.
By tricking your body into thinking GLP-1 levels are high, Wegovy and Mounjaro work to:
-
Slow down stomach emptying
-
Improve blood sugar regulation
-
Reduce glucose release from the liver
-
Tell your brain that you feel full
Mounjaro takes things one step further by mimicking a second hormone called glucose-dependent insulinotropic polypeptide (GIP). This may explain why 62.9% of people lost at least 20% of their starting body weight in clinical trials when taking the highest Mounjaro dose. Wegovy is almost as effective - 37.4% of people taking Wegovy lost 20% or more of their body weight.
Mounjaro and Wegovy make it easier to eat less and lose weight. But they're only effective when used alongside lifestyle changes, such as exercising more and eating a healthier, balanced diet. For the best results, Mounjaro or Wegovy should also be injected on the same day of the week, at the same time.
Over Christmas, routine goes out the window and it can be hard to keep on top of healthy eating, working out, and even remembering your medication. But it's important to try to stick to a healthy diet as much as you can and continue taking your weight loss injection every week as normal.
Do Christmas Foods Interact with Weight Loss Medications?
There are not any foods that are listed in the medication information leaflet that interact with Wegovy or Mounjaro and lead to a serious reaction or make the medications less effective. But certain foods can increase the chances of experiencing side effects, such as indigestion or nausea.
Spicy, fried, and greasy foods are more likely to make you feel sick. As weight loss medications can also make you feel sick, it's best to limit how much fatty and spicy food you eat to avoid making yourself feel worse.
Fatty foods can also stay in your stomach longer. As Wegovy and Mounjaro also slow down stomach emptying, fatty foods may lead to stomach discomfort.
Fatty Christmas foods include:
-
Cheese and cream
-
Butter and other animal-derived fats
-
Fatty meats
-
Creamy or pastry-based desserts
-
Roast potatoes and crisps
Another common side effect of weight loss drugs is heartburn or acid reflux. Acidic foods, spicy foods, and alcohol can all make acid reflux worse.
Can You Enjoy Christmas Treats While on Weight Loss Injections?
It's unrealistic to avoid all of your favourite festive foods, but the key is to indulge mindfully. Take small amounts of the fatty, sugary foods (like pigs in blankets, roast potatoes, and desserts) and include more vegetables on your plate.
Try to eat slowly and savour every bite of your sweet treats like mince pies and Christmas cake. If you're feeling peckish, try to snack on fruit and nuts rather than chocolates and crisps. Even better if it's something that requires time to crack open or peel, as it gives you time to think about if you really want it.
Although it can be enjoyable, alcohol contains lots of calories and can disrupt your weight loss efforts. To avoid overindulging:
-
Opt for lower alcohol drinks, and be careful with high-calorie ciders and beers
-
Drink water in between alcoholic drinks
-
Try a low-calorie CBD drink instead for a relaxing effect with fewer calories (but avoid consuming more than 10mg of CBD a day)
Managing Challenges: Preventing Weight Gain During the Festive Season
Combatting Food Noise
"Food noise" is sometimes used to refer to the internal voice that talks to you about food, even when you're not hungry. Some people taking GLP-1 medications report that the medication quietens their "food noise", making it easier to eat less and not think about food.
If you continue taking your weight loss injections as prescribed over the festive period, they will continue to have benefit and help with the "food noise", helping you to avoid temptation.
Exercise Regimes to Balance Festive Indulgence
Although you might not be able to fit in your usual workouts, there's usually time over the Christmas period for a home workout or to go for a run. Walking with friends and family is another way to get some exercise in while socialising.
Preventive Tips to Avoid Weight Gain
Even if your routine is disrupted, it's important to take your weight loss injection at the usual time on the usual day. Set a reminder on your phone if you're worried you'll forget. Don't be tempted to skip a dose in order to overindulge, as this can disrupt your progress and you may need to restart your treatment at the lowest dose.
Try not to sit down at a Christmas meal or buffet when you're really hungry - have a few healthy snacks earlier in the day to avoid this. When you're eating, enjoy each mouthful mindfully and opt for smaller portions of high-calorie and fatty foods.
Addressing Myths About Weight Loss Medications and Christmas
Are Weight Loss Injections a Quick Fix for Festive Overindulgence?
Although weight loss injections can make you feel less hungry and less likely to want an alcoholic drink, they only lead to weight loss alongside a balanced diet and regular exercise. If you eat a large number of calories over Christmas, weight loss injections won't help you burn them off.
Should You Skip Doses to Indulge in Christmas Feasts?
No, it's important to use your medication as prescribed and take your weight loss injections as normal. Skipping doses is strongly discouraged. This may mean you may have to start again from the lowest dose to avoid experiencing side effects.

FAQs
Can I eat Christmas treats while using weight loss injections?
Yes, you can enjoy some Christmas treats while taking Mounjaro or Wegovy, but try to eat smaller portions of those high-fat, high-calorie festive favourites to avoid weight gain.
Should I adjust my dosage over the Christmas period?
No, you should never adjust your medication dose without advice from a healthcare professional. Unless you have any scheduled dose increases coming up, it may be best to avoid any dose changes until your routine is back to normal. That way, you'll know whether disappointing results or side effects are down to the medication or Christmas indulgence.
What are some festive foods that pair well with GLP-1 medications?
Fatty, spicy, and acidic foods may cause similar side effects to your GLP-1 medications, such as acid reflux, nausea, and bloating. To avoid this, try to fill up on vegetables at Christmas dinner and take small amounts of fatty meats, cheese, and desserts that can trigger these symptoms.
How can I prevent side effects while enjoying Christmas dinner?
Eating mindfully helps you to enjoy every bite of your favourite foods while giving you time to feel full. As fatty foods stay in your stomach longer and GLP-1 medications slow down stomach emptying further, try to limit how much fatty food you eat to avoid feeling uncomfortable.
