If you live with obesity like me, you know the exact panic that hits when the scale stops moving. You take your GLP-1 medication for months, watch the weight come off steadily, and then suddenly hit an absolute wall. If you have experienced these frustrating stalls or plateaus, you probably felt exactly what I did: fear that the medication stopped working, or the heavy burden of shame that your willpower failed you yet again.
I wanted real answers about my own body, so I asked obesity medicine specialist Dr. Ali Novitzki about it on an episode of The Plus Sidez Podcast. The clarity she gave me completely changed how I look at my journey. She helped me realize that my medication did not fail, and neither did I. My body was just navigating the natural physical phases of a weight loss journey.
The Moving Rate of Weight Loss Dr. Ali explained that weight loss on a GLP-1 is a dynamic process. It does not look like a straight, continuous drop on a graph. Instead, she maps it out as a sequential progression of changing speeds:
The Rapid Phase: At the very beginning of your journey, weight tends to drop quickly. This happens because the medication suddenly quiets your food noise and suppresses your appetite, resulting in a sharp drop in your overall food intake.
The Slowing Phase: As you move further along, your rate of loss naturally begins to get slower. Your body starts recognizing the change in mass and tries to adjust to its new baseline weight.
The Final Phase: Eventually, you reach a phase where weight loss becomes very slow. This is the exact point where progress frequently pauses, and it can feel like a total, permanent plateau.
Dr. Ali notes that she refers to these as biological stages or phases because they directly reflect how your internal metabolism behaves as your physical body mass changes.
What is Happening Inside Your Body During a Stall?
Learning what is happening biochemically when the scale freezes was a massive lightbulb moment for me. Dr. Ali explained that when we hit that very slow phase, it is often because our internal metabolic engine has changed.
Our skeletal muscle acts like a primary pool for glycogen storage, actively pulling fuel and food energy straight out of our bloodstream to keep our systems running. Gaining or keeping your muscle mass improves your insulin sensitivity, which means your body needs less insulin to process the food you eat.
But if your engine shrinks, your baseline insulin requirements actually go up. Because insulin is a storage hormone, higher baseline levels tell your body to hold onto fat tissue, which completely freezes your weight loss progress. Your plateau isn’t a sign of failure; it is your baseline metabolic rate slowing down to adapt to a changing internal environment.
The Plan to Get Back in Control: Protecting your metabolism through these changes does not require complex routines or extreme calorie cutting. Dr. Ali shared a simple, practical framework with me to support long-term metabolic health and safely navigate these natural shifts:
The 100-Gram Protein Target: Eating roughly 100 grams of protein daily provides the necessary cellular building blocks your system needs to preserve its active lean tissue.
The 10-Minute Resistance Framework: Committing to just 10 minutes of strength training three days a week provides enough tension to support your metabolism. Dr. Ali assured me you can easily do this at home using your own body weight, resistance bands, or a basic kettlebell.
Living with obesity means managing a complex, chronic biological condition. When your progress pauses, it is not a moral failure. It is just your body navigating a survival mechanism.
