Summary
On episode 678 of 40+ Fitness, Coach Allan sits down with Dr. Alexandra Sowa, a trailblazer in obesity medicine dually certified in internal medicine and obesity medicine, a clinical instructor at NYU School of Medicine, and the founder of SoWell Health, a telehealth practice. She writes for The New York Times and The Atlantic and is the author of The Ozempic Revolution: A Doctor’s Proven Plan for Success to Help You Reverse Obesity, End Yo-Yo Dieting, and Protect Yourself from Disease.
Alexandra explains what GLP-1 and GIP medications actually do in the body: they are not just appetite suppressants, they act on the brain, the gut, and the pancreas to quiet food noise, slow gastric emptying, and stabilize blood sugar. She is direct about the tradeoffs too, including common side effects, the mental work required, and the reality that most people will need to stay on these medications long term to keep the benefits.
The conversation also covers why protein, strength training, and hydration become non-negotiable once appetite drops, and how to think about the drugs as one tool inside a larger foundation of habits rather than a magic fix.

Key Takeaways
- GLP-1 and GIP are naturally occurring gut hormones, not just appetite suppressants. They have receptors throughout the brain, blood vessels, heart, and kidneys, which is why these drugs produce health benefits well beyond weight loss. Alexandra calls this a hormonal replacement for a system that has become dysregulated by the modern food environment.
- The drugs work through three mechanisms: the brain, the gut, and the pancreas. They quiet food noise so you stop thinking about food constantly, slow gastric emptying so meals keep you full longer, and improve how the pancreas releases insulin to normalize blood sugar. Only about 12 percent of American adults are fully metabolically healthy, which is why the pancreatic effect matters so broadly.
- Most of the side effects are direct byproducts of how the drug works, and they are manageable with the right habits. Nausea, constipation, and diarrhea come from slowed digestion, so Alexandra has patients start fiber supplementation, electrolytes, and hydration protocols before they even begin the medication, rather than reacting after problems start.
- Protein first is the core nutrition rule, and it means physically eating the protein before anything else on the plate. Eating protein first blunts the blood sugar spike from carbohydrates and helps preserve muscle during weight loss, which matters for anyone, not just people on GLP-1s. She has patients aim for roughly 20 to 40 grams of protein per meal and deliberately deprioritizes bulky vegetables early on since a suppressed appetite leaves little room for both.
- Muscle loss during rapid weight loss is a nutrition and training problem, not a defect of the drug itself. Any significant weight loss, medicated or not, costs you both fat and muscle. Studies show body composition is actually slightly better on GLP-1s than with calorie restriction alone, but protein intake and resistance training are what determine how much muscle you keep.
- Weight loss is not linear, and the 10-pound panic is a predictable phase. Patients who lose their first 10 pounds often assume the medication has stopped working or that this attempt will fail like every other diet. Alexandra tells people up front to expect plateaus so they do not spiral into the negative thinking that undoes months of progress.
- These medications are approved for long-term, potentially lifelong use, and most people will need to stay on them to keep the benefits. Once food noise disappears and healthy habits take hold, people often assume they no longer need the drug. But maintaining improved lipid profiles, glucose control, and the weight loss itself generally requires staying on the medication.
- Identify your real “why” before starting, because losing weight does not change who you are on the inside. Alexandra asks patients for three whys, one of which can be about vanity but the rest need to be bigger, like being able to get on the floor and play with a grandchild. She keeps tabs on those whys and reminds patients of them when motivation dips.
- Alexandra’s three strategies to get and stay well: dig deep to identify your real reasons for pursuing health and keep coming back to them; journal and self-reflect so emotions get processed instead of scrolled away on a phone; and deliberately notice and enjoy simple moments of happiness, especially once food and drink are no longer the center of every gathering.
“It’s not a magic wand, voila, because that’s actually not how it works.”
