If you have been considering weight loss medication and you live in Las Vegas or Nevada, this is the guide I give my patients. It covers everything from how these medications work to what to expect from a quality clinic versus a telehealth mill.
Right now, the most effective medications for weight loss are GLP-1 receptor agonists: semaglutide (Ozempic for diabetes, Wegovy for weight loss) and tirzepatide (Mounjaro for diabetes, Zepbound for weight loss). These medications have genuinely changed what weight loss looks like. Unlike older weight loss pills that worked through stimulation or metabolism boosting, these medications work on appetite regulation at the brain level.
Your body naturally makes GLP-1, a hormone released by your gut after eating. It tells your pancreas to release insulin, slows stomach emptying, and signals your brain that you are full. GLP-1 medications amplify this signal.
When you take a GLP-1 medication, your brain receives stronger "fullness" signals. You eat smaller portions naturally. Food cravings quiet down. Your relationship with food changes fundamentally.
As a neurologist, I can tell you that this is not willpower. This is neurobiology. The appetite centers in your hypothalamus are responding to corrected hormonal signaling. This is why GLP-1 therapy works for so many people when diet and exercise alone have not.
Week 1-2: Initial Consultation
A proper weight loss clinic should spend 45-60 minutes on your first visit. This includes:
Weeks 3-4: Starting Medication
You begin at the lowest dose. For semaglutide, that is 0.25 mg weekly. For tirzepatide, it is 2.5 mg weekly. Side effects are usually minimal at this dose. Some patients notice mild appetite reduction. Others notice nothing yet.
Weeks 5-12: Dose Escalation
Every 4 weeks, the dose increases. This is when most patients start to feel the medication working. Appetite decreases noticeably. Portion sizes shrink naturally. The food noise quiets. GI side effects may flare temporarily with dose increases but usually resolve within 1-2 weeks. Monthly check-ins ensure you are tolerating the medication well.
Weeks 12-24: Reaching Maintenance Dose
By this point, you are at or near your target dose. Weight loss is typically steady at 1-2 pounds per week. Labs are repeated to track metabolic improvements. Your protocol may be adjusted based on how you are responding.
At 6 months: Most patients lose 10-15% of starting body weight.
At 12 months: Average is 15-22% of starting body weight depending on medication and individual response.
What matters: These are averages. I have had patients lose 25% of their body weight and others lose 8%. Genetics, metabolism, lifestyle, and adherence all factor in. But the vast majority of patients who stick with the program through the full titration phase see meaningful results.
Nevada has some of the highest obesity rates in the US. The reasons are complex: sedentary culture, extreme heat making outdoor activity difficult, shift work schedules that disrupt sleep and eating patterns, and food-centric social environment. For many residents, diet and exercise alone cannot overcome these environmental and metabolic pressures. GLP-1 therapy is not lazy. It is smart medicine for a real problem.
Some telehealth companies will sell you GLP-1 medications after a brief questionnaire. This is dangerous. Before starting any GLP-1 therapy, you need:
If a clinic offers a prescription without these things, run. That is not medicine. That is profit.
With insurance: Semaglutide typically has broader coverage than tirzepatide, though this is changing. Tirzepatide coverage is expanding rapidly.
Cash-pay: Both medications available through quality compounding pharmacies at $300-600 per month depending on dose and supplier. This is significantly less than brand-name pricing.
Telehealth: If you are outside Las Vegas but in Nevada, you can have virtual consultations with lab work completed at any Quest or Labcorp. Medication ships to your home.
