GLP-1 Weight Loss Ann Arbor | Medical Weight Loss Michigan

Key takeaways

• If weight keeps climbing despite real effort, hormones, not willpower, are usually the reason.
• GLP-1 medications restore the gut signal that tells your brain you are full.
• In major trials, semaglutide produced about 15–17% weight loss and tirzepatide about 20–22%.
• We test your metabolism first and use brand-name FDA-approved medication (Wegovy® or Zepbound®) or, where appropriate and clearly disclosed, compounded semaglutide or tirzepatide (which has not been reviewed or approved by FDA), with a slow dose build-up.
• Your $35 first visit is applied toward your plan; most patients start within 7–10 days.

If your labs come back “normal” but the weight keeps climbing, despite tracking food, working with trainers, and trying every plan, you are not failing. Your biology is working against you in ways most doctors do not address until you are already pre-diabetic. That is the conversation that brings most people to our Ann Arbor clinic asking about GLP-1 therapy.

Why “eat less, move more” keeps failing

The old calorie model, eat less than you burn, is neat math and incomplete medicine. Your body defends its weight with surprising precision. After months of dieting, your hunger hormone (ghrelin) rises and your fullness hormone (leptin) drops. Your body also quietly turns down how many calories it burns. You get hungrier, your metabolism slows, and the weight comes back. That is why 80–95% of people regain the weight within five years. It is not weakness. It is predictable hormone change. The fuller story is in medical weight loss vs diet culture.

How GLP-1 medications actually work

GLP-1 is a gut hormone your body releases after eating. It tells your brain “you have had enough.” In many people with obesity, that signal is weak. GLP-1 medications (semaglutide and tirzepatide) restore it. They slow how fast your stomach empties so you stay full longer. They steady your blood sugar. And they quiet the constant background “food chatter” in your brain. Most people describe not just eating less, but truly wanting less.

In the major trials, semaglutide produced about 15–17% average weight loss and tirzepatide about 20–22%. That is close to surgery-level results without surgery. Which one fits whom is covered in semaglutide vs tirzepatide. GLP-1 receptors also sit well outside the appetite centers. That is why research now extends into heart and metabolic protection, covered in GLP-1 therapy beyond weight loss.

What clinical response looks like

What I see in clinic: a patient who had tried keto, fasting, and two years with a nutritionist. Her fasting insulin was high, an early sign of insulin resistance (cells that stop responding to insulin, so blood sugar and belly fat rise). On a slow, low-to-higher dose plan, the food chatter quieted within a few weeks. She lost weight steadily without counting calories, about 1–2 pounds a week during the build-up, and her insulin normalized. It is not universal. Some people get nausea while the dose goes up, some lose less, and a few do not respond much. But for most people whose bodies resist ordinary dieting, this treats the biology that willpower cannot.

Our approach in Ann Arbor

We do not hand out GLP-1 at the first visit. We start with real metabolic testing: fasting insulin and glucose, HbA1c (a 3-month blood-sugar average), cholesterol, and a full thyroid panel. Sometimes the real problem is an underactive thyroid, chronic stress, or a hormone imbalance that responds better to a different fix. A man with low testosterone, for instance, may lose weight just by correcting his hormones (see testosterone therapy).

When GLP-1 is the right tool, we use brand-name FDA-approved medication or a clearly disclosed compounded version (compounded drugs have not been reviewed or approved by FDA), with a slow, careful dose build-up to limit nausea. We protect your muscle with protein and strength training, and we plan for long-term maintenance from the start. We never use gray-market sources (more on the compounding rules).

What to expect

Your first visit covers your history, past attempts, and any reasons not to use these medications, such as a personal or family history of medullary thyroid cancer or MEN2. There is a fuller walkthrough in what to expect at your first medical weight loss consultation. We order labs first. Most people start within 7–10 days, with check-ins every four weeks while we adjust the dose. The $35 consultation applies toward your plan if you proceed.

Most patients pay out of pocket, since insurance coverage for weight loss is inconsistent. We are upfront about cost before you start. The full breakdown is in how much medical weight loss costs in Ann Arbor, and many patients pay with an HSA or FSA card.

Frequently Asked Questions

Is semaglutide safe if I'm not diabetic?

Yes. Wegovy® (semaglutide) and Zepbound® (tirzepatide) are FDA-approved for chronic weight management in adults without diabetes who have a BMI of 30+, or 27+ with a weight-related condition. Compounded versions have not been reviewed or approved by FDA. Using them before diabetes develops may even help prevent it. Most side effects are stomach-related and ease with slow dosing.

How much weight can I expect to lose?

Most people lose about 15–20% of their starting weight over 12–18 months, though it varies. A 200-pound person might lose 30–40 pounds. Weight loss usually peaks around 14–16 months. Keeping it off generally needs an ongoing, lower maintenance dose.

What are the side effects?

Nausea is the most common, especially while the dose goes up, and usually fades within a few weeks. Constipation and occasional diarrhea happen too. Serious problems like pancreatitis are rare (under 1%). That is why we monitor symptoms and check labs along the way.

How fast will I see results?

Most people notice less appetite and some early weight loss in the first 2–4 weeks, with bigger changes by week 12. Metabolic gains like lower fasting insulin often show up within 8–12 weeks, sometimes before major weight loss.

Does insurance cover it?

Coverage is inconsistent. Some commercial plans cover it with prior authorization. Many exclude weight-loss medications, and Medicare generally does not cover them for weight loss alone. What changed for Michigan Medicare in 2026 goes through that in detail. Most of our patients pay out of pocket, and we help with prior authorization when it is possible.

Will I have to take it forever?

Often, at a lower maintenance dose, because obesity is a chronic condition. Stopping usually leads to regain. Some people can step down further over time. We are transparent about this from day one.

If this sounds familiar

Maybe you have spent years trying to override your biology with discipline. Maybe you are heading toward pre-diabetes and want to act before it becomes disease. Either way, this is the conversation we have daily. GLP-1 is not for everyone and does not replace good nutrition and movement. But for people whose bodies resist dieting, it is a real path that respects the biology. Your first step is to book your $35 first visit or call (734) 436-3357.
