Welcome to The Peptide Podcast. Today we’re going to talk about something that almost everyone on a GLP-1 journey hits eventually, the weight loss plateau.
It starts like this: you begin a GLP-1 like semaglutide or tirzepatide, and for the first few weeks or months, the weight seems to fall off. You’re eating less, not obsessing over food, and for the first time in a long time, it feels… easy.
Then one day, the scale just stops moving.
You’re not doing anything different. You’re still taking the meds. Still trying to eat well. Maybe you’re walking more or lifting weights. But suddenly, nothing’s happening—and the frustration kicks in.
Sound familiar? Let’s talk about what’s really going on.
1. What Causes the Plateau?
First of all, if you’re in this place right now: you didn’t mess up. GLP-1s are incredibly effective at reducing appetite and creating an initial calorie deficit, which is why people lose weight so quickly in the beginning.
But your body isn’t just going to let that continue unchecked. It adapts. This is called adaptive thermogenesis—a fancy way of saying your body becomes more efficient. You start burning fewer calories at rest than you did before.
Your resting metabolic rate actually drops beyond what you’d expect just from losing weight alone. It’s a survival mechanism.
So what worked at the beginning—eating less and moving a bit more—might no longer be enough to keep the scale moving.
This is totally normal.
2. Metabolism & Muscle: Why Strength Training Matters Now More Than Ever
So now that we know why the plateau happens, let’s talk about things we can do to help us get over it.
Something that often gets overlooked but is absolutely critical—especially if you’re on a GLP-1 or in any kind of calorie deficit.
Resistance training is not optional. It’s non-negotiable.
Here’s why.
When you’re losing weight—whether it’s from a medication like semaglutide or just eating in a calorie deficit—your body isn’t just pulling energy from fat. If you’re not careful, it’s also going to break down lean muscle tissue.
And the more muscle you lose, the slower your metabolism gets. Why? Because muscle is metabolically active tissue. It burns calories even when you’re doing absolutely nothing. So if you’re not actively sending a signal to your body to keep that muscle, it’ll start to let it go.
That’s where resistance training comes in.
When you lift weights or do bodyweight exercises—think squats, push-ups, resistance bands, even heavy housework—you’re telling your body: “Hey, I need this muscle. Don’t burn it for fuel.”
This is especially important for those on GLP-1s because these meds reduce appetite so significantly that you might not be eating enough protein—or enough calories in general—to maintain muscle without that extra stimulus.
So if you’ve hit a plateau or want to prevent one, ask yourself:
- Am I strength training at least two to three times a week?
- Am I prioritizing movements that challenge large muscle groups—like legs, glutes, chest, and back?
- Am I fueling my workouts with enough protein?
And let me be really clear, you don’t have to become a gym rat. You don’t have to lift crazy heavy weights. But you do have to move your muscles in a meaningful, consistent way.
Protecting your lean mass is one of the best ways to keep your metabolism humming—not just during your weight loss journey, but after it too.
Because this isn’t about just losing weight—it’s about building a strong, metabolically healthy body that can maintain that weight loss for life.
3. Mindset Check: The Plateau Is Not a Failure
Now, let’s get into the mental side of this journey—because it’s just as important as nutrition, movement, and medication.
One of the biggest challenges people face—especially when progress slows—is the mental roller coaster that comes with watching the scale. And I’ll be honest: weighing yourself every single day is not ideal.
Here’s why.
Your body weight naturally fluctuates. Daily.
And those fluctuations have nothing to do with your actual fat loss or long-term progress. Instead, the number on the scale is influenced by things like:
- Hydration status – If you’re slightly dehydrated, the scale may dip. But if you drank a ton of water the day before or had more salty food, it may go up due to water retention.
- Glycogen stores – When you eat carbs, your body stores them in your muscles and liver as glycogen, and for every gram of glycogen, your body stores about 3–4 grams of water. So a pasta dinner or even a healthy grain bowl can cause a temporary increase on the scale.
- Digestive contents – Let’s be real: if you haven’t had a bowel movement (constipation) or just ate a bigger meal, the scale might reflect that. Doesn’t mean you gained fat.
- Inflammation or illness – If you’re recovering from an illness, injury, or even a hard workout, your body retains extra water as part of the healing process. Again—temporary.
But here’s what happens when we don’t understand this, we step on the scale, see a higher number, and panic. We question everything—“Am I doing something wrong? Is the medication not working? Should I eat less?” And that mindset spiral can lead to unnecessary stress, restriction, or even giving up.
So what should you do instead?
Focus on trends over time, not daily weigh-ins. Weigh yourself once a week at most, ideally at the same time of day, under the same conditions (like first thing in the morning before food or water). Or better yet—track non-scale victories: clothes fitting better, improved energy, reduced cravings, less inflammation, better digestion, even clearer skin. These are all signs your body is healing and progressing.
Remember, your worth is not defined by a number, and fat loss is not always linear. There are ups, downs, pauses, and breakthroughs—and all of them are part of the process.
4. Habits: Recheck Your Routine
Now, here’s where we get really honest. Because as the months go by, it’s normal for habits to loosen up.
Maybe you’re not tracking portions quite as closely. Maybe your steps have dropped. Maybe “just a bite” here and there has crept in more often than you realize.
This doesn’t make you bad or lazy—it makes you human.
But if progress has stalled, it’s worth revisiting the basics:
- Are you eating mostly whole, minimally processed foods?
- Are you staying hydrated and watching added sugars?
- Are you eating out frequently without paying attention to portions?
- Are you still moving your body every day?
Small shifts can make a big difference.
5. Food Noise: Why It’s Sneaking Back
One of the most exciting things about GLP-1s is how much they reduce food noise—that constant mental chatter about snacks, cravings, and what’s in the fridge.
But for many people, that quiet doesn’t last forever.
Over time, especially as your body adapts to the medication or your dose levels off, food noise can return. You might find yourself thinking about food more often or wanting things you weren’t craving before.
This doesn’t mean the med has stopped working. It means your biology is adjusting.
What helps:
- Keeping meals protein-forward and fiber-rich
- Eating at regular times to avoid dips in energy or blood sugar
- Identifying emotional vs. physical hunger
- Managing stress and sleep, which both drive cravings
This is the time to build real strategies—so you’re not relying on the med alone.
6. Emotional Eating
This brings me to my next point. Let’s talk about something that often flies under the radar but can make a huge difference in your weight loss journey—emotional eating. This is when feelings like stress, boredom, anxiety, or sadness trigger you to eat, even if you’re not physically hungry. It’s totally normal, and many people experience this at some point.
Now, GLP-1 medications like semaglutide or tirzepatide do a great job at reducing physical hunger by influencing hormones that control appetite. But they don’t always fully address the emotional side of eating. So, even if your stomach feels satisfied, those emotional triggers can still push you toward cravings or eating for comfort.
Recognizing emotional eating is the first step. Try to notice when you’re eating because of feelings rather than hunger. Strategies like mindful eating, journaling your emotions, or finding alternative outlets—like walking, meditation, or chatting with a friend—can really help.
If emotional eating is a big hurdle, working with a therapist or counselor who specializes in behavioral health can provide tools to manage those feelings without turning to food.
Remember, managing emotional eating alongside your GLP-1 treatment can make a huge difference in overcoming plateaus and reaching your goals more sustainably.
7. Set Realistic Expectations: Fat Loss Isn’t Linear
Lastly, I want to talk about setting realistic expectations. I can’t stress the following enough. You are not supposed to lose weight every single week forever.
Your body needs breaks. Your metabolism needs to reset. And your mind needs time to adapt to this new version of you.
Think of your fat loss journey like a staircase—not a slide. There are flat spots before the next drop.
And guess what? Some of the most important changes—like maintaining your weight, building strength, or stabilizing your habits—happen during those flat spots.
You don’t need to push harder or go more extreme. You just need to keep showing up consistently.
My Final Thoughts: Trust the Process
The bottom line is trust the process. If you’re on a GLP-1 and the scale has stalled, take a deep breath. This is a normal part of the process. It’s not the end—it’s just a signal to pivot and refocus.
We want to build muscle. Prioritize protein. Revisit your habits. Stay active. And most importantly, don’t give up.
