10 Reasons You Are NOT Losing Weight On GLP-1s

10 Reasons You Are NOT Losing Weight On GLP-1s

Let’s be honest. You started taking a medication like Tirzepatide because you heard it was a powerful tool for weight loss. So, it can be really frustrating and confusing when you step on the scale and the number isn’t moving like you hoped. First, know this: you are not alone, and it’s not your fault.

This guide is like a friendly checklist to help you figure out what might be going on. We will walk through the 10 Reasons You Are NOT Losing Weight On GLP-1s. And more importantly, we’ll give you simple, easy steps you can take to fix each one.

At Tirzepatide Medics, we know that weight loss is a journey with ups and downs. We’re here to help you figure out every step.

1. Your Dose is Still Too Low

The “Why”: GLP-1 medications are started on a very low “starter dose.” The main reason for this is to let your body get used to the medicine slowly and safely. The real, powerful weight loss often doesn’t start until you move up to higher doses, which can take a few months.

What You Can Do:

The best advice here is to be patient and trust the process. Think of the first month or two as your body’s “getting ready” phase, not a race. A safe and effective treatment plan is always designed this way to keep you safe and set you up for success in the long run.

2. You’re Experiencing “Calorie Creep”

The “Why”: The medicine does a great job of making you feel full during meals. But calories can be sneaky. They can hide in places you don’t expect, like salad dressings, cooking oils, sauces, and sugary drinks. These can add hundreds of calories to your day without making you feel full at all.

What You Can Do:

Take a quick look at the “extras” you are eating and drinking. Pay close attention to liquid calories from sodas, juices, and those fancy coffee drinks. Try using lighter dressings on your salads or measuring the oil you use for cooking.

3. You’re Not Eating Enough Protein

The “Why”: Protein is the most important nutrient when you are trying to lose weight. It does three amazing things: it makes you feel full, it keeps your blood sugar stable, and it tells your body to burn fat instead of muscle. If you don’t eat enough protein, you might still feel hungry, even on the medication.

What You Can Do:

Make protein the star of every meal you eat. A good goal is to get about 20-30 grams of protein each time you eat. Easy sources are things like chicken, fish, eggs, Greek yogurt, and beans.

4. You’re Doing the Wrong Kind of Exercise (or None at All)

The “Why”: Any kind of movement is good for you. But if you are only doing cardio, like walking or running, you might be missing a key piece of the puzzle. Without some kind of strength training, your body might lose precious muscle along with the fat.

What You Can Do:

Try to add some resistance training to your week, maybe 2 or 3 times. This doesn’t mean you have to become a bodybuilder! It can be as simple as lifting some weights, using resistance bands, or even just doing squats and push-ups with your own body weight.

5. The Scale is Lying: You’re Gaining Muscle!

The “Why”: This is the best reason on the list! If you have started doing resistance training, you might be building new muscle at the same time you are losing fat. Muscle is much more dense than fat, which means it takes up less space. So, the number on the scale might not change, but your body is getting smaller and stronger. This is one of the most positive of the 10 Reasons You Are NOT Losing Weight On GLP-1s.

What You Can Do:

Stop focusing only on the scale. Pay attention to the “non-scale victories.” How are your clothes fitting? Do you have more energy? Try taking your measurements with a simple tape measure once a month. These are much better ways to see your amazing progress.

At Tirzepatide Medics, our online prescription service offers a safe and affordable way to start your journey. For a flat monthly fee that starts at $399 for your first month (then $299/month), you get your online doctor’s visit, your prescription, and your medication delivered to you.

This all-inclusive price makes it easy to get started on a treatment that helps people lose an average of 20% of their body weight.

6. You’re Dehydrated or Constipated

The “Why”: These medications can slow down your digestion a bit. This can sometimes lead to constipation, which can literally add a few pounds of weight on the scale. Also, if you’re not drinking enough water, your body might hold onto water weight.

What You Can Do:

Make water your best friend. Try to drink at least 64 ounces every day. It’s also a great idea to eat more fiber from vegetables and whole grains to keep your digestion moving smoothly.

7. Your Sleep is Poor or Your Stress is High

The “Why”: When you don’t get enough sleep or you are very stressed, your body makes more of a hormone called cortisol. Cortisol tells your body to store fat, especially around your belly. It can work directly against all your hard work.

What You Can Do:

Try your best to get 7-8 hours of good sleep each night. Also, find healthy ways to lower your stress. This could be going for a walk, listening to music, or just taking five minutes to breathe deeply.

8. You’re Drinking Your Calories

The “Why”: Alcohol can be a real roadblock for weight loss. First, it’s full of empty calories. Second, it can make you more likely to make poor food choices. And third, it can actually pause your body’s ability to burn fat.

What You Can Do:

Be mindful of how much alcohol you are drinking. If you do have a drink, try to choose lower-calorie options. And pay attention to how it affects your hunger later.

9. Other Medications Are Interfering

The “Why”: Some other types of prescription drugs can make it harder to lose weight. Things like certain steroids or some antidepressants can have weight gain as a side effect.

What You Can Do:

Make sure your doctor knows about every single medication and supplement you are taking. They can check to see if anything might be working against your efforts.

10. You’re Comparing Your Journey to Others

The “Why”: It is so easy to go online and see amazing before-and-after pictures. It can make you feel like you are failing if your own progress isn’t as fast. But everyone’s body and journey are completely different.

What You Can Do:

Stop comparing! Your only competition is the person you were yesterday. Focus on your own progress, your own non-scale victories, and how much better you are feeling.

When in Doubt, Talk to Your Provider

The “Why”: You are not supposed to figure all of this out by yourself. If you have tried these tips and you still feel stuck, it is time to talk to your healthcare provider. They are your best and most valuable resource.

What You Can Do:

Never be afraid to reach out for help. Your provider can look at your progress, give you personalized advice, and make sure there isn’t another medical reason for your plateau. A direct line to your care team, like our secure patient portal, is designed for this exact reason—to give you the support you need.

Conclusion: Turning a Plateau into Progress

Feeling stuck can be frustrating, but it doesn’t have to last forever. By going through this checklist, you can turn that frustration into action. Understanding the 10 Reasons You Are NOT Losing Weight On GLP-1s gives you the power to make small changes that can make a big difference. You can get back on track and continue on your path to success.
