About this listen

 Today’s episode was sparked by a Medscape article that immediately grabbed my attention. The headline essentially said that set point weight does not seem to decrease with the use of GLP-1 medications. If you’re taking Semaglutide, Tirzepatide, or any of the current weight-loss medications, that line alone is enough to make your heart skip a beat. For many people, these medications have felt like the first time in their lives that their hunger was quiet, their cravings were manageable, and their weight finally responded. So when you hear that set point may not actually change — that the body might be waiting to crawl right back to its original weight — the fear becomes very real. But like most things in physiology, the headline didn’t tell the whole story. And that’s what this episode unpacks. What Set Point Actually Is — And Isn’t Set point is often described as the weight your body “likes” to sit at, but that’s far too simplistic. Your body isn’t trying to sabotage you; it’s trying to protect you. Deep in your brain — specifically the hypothalamus — you have a kind of metabolic thermostat. It constantly monitors hormones, nutrient availability, inflammation, hunger cues, stress levels, and even the kinds of foods you routinely eat. All of this information is used to determine what weight range the body feels safest maintaining. When you drop below that range, or lose weight quickly, the brain interprets it as a potential threat. Hunger rises. Cravings intensify. Food becomes more rewarding. Energy levels dip. Your metabolism slows. Your movement decreases without you even noticing. These aren’t character flaws — they’re ancient survival mechanisms. And here’s the part that matters most: your set point is not permanent. It adapts based on your physiology. Your environment. Your habits. Your muscle mass. Your food quality. Your inflammation levels. Your stress. Your sleep. Your blood sugar stability. Your set point can shift up or down — but it doesn’t shift just because you lost weight. It shifts when the biology underneath the weight changes. So Where Do GLP-1 Medications Fit Into All of This? GLP-1 medications do something incredibly powerful: they create the feeling of a lower set point. Hunger drops. Fullness increases. Cravings go quiet. Food stops dominating your thoughts. You feel in control. You naturally eat less because your biology finally lets you. But it’s critical to understand why this happens. GLP-1s don’t magically reset the metabolic thermostat. They simply turn down the noise that makes weight loss nearly impossible for some people. They reduce hunger signals, slow digestion, balance blood sugar, dampen reward-driven eating, and improve certain hormonal pathways. While you’re on the medication, your body behaves as though it has a lower defended weight. You’re in the zone. You’re losing weight. Everything feels easier. But — and this is exactly what the Medscape article was pointing to — once the medication is removed, the underlying system is still the same. If the physiology that created the higher set point hasn’t changed, the body will start nudging you back up toward where it felt safe before. Hunger returns. Cravings return. The pace of eating speeds up. You start thinking about food again. You don’t get as full as quickly. The thermostat simply goes right back to its previous setting. This is why so many people regain weight after stopping GLP-1s. It isn’t because the medication “stopped working.” It’s because the set point didn’t shift, and the hunger cues were only being temporarily managed. So What Does Lower a Set Point? This is where physiology and lifestyle meet. If you want the weight to stay off — with or without medication — your biology has to change in ways that make your brain feel safe at a lower weight. And that doesn’t come from being hungry. It comes from being metabolically supported. Muscle is one of the biggest drivers. The more muscle you carry, the more efficiently you handle glucose, the more stable your metabolism becomes, and the less defensive your body is about holding fat. Protein intake matters for the same reason — it improves satiety, stabilizes cravings, and helps maintain lean mass. Movement — especially strength training — tells the body, “We’re active, we’re strong, and we are not in a famine.” That’s when your metabolism relaxes and your appetite becomes more biologically appropriate. Blood sugar stability matters enormously. When glucose swings up and down, cravings and hunger spikes follow — and your body fights to get back to the heavier weight where it felt more stable. Even inflammation plays a part. A highly inflamed body is a defensive body. It clings. It protects. It stores. Lower inflammation sends the opposite signal: we’re safe, we’re nourished, we can let go. None of these changes come from medication alone. The medication simply ...
