Medical Weight Loss in Raleigh: Comparing Your Options
Medical weight loss is a physician-supervised approach to weight management that uses FDA-approved medications, peptide therapy, metabolic optimization, and functional medicine interventions tailored to each patient's biology, rather than relying solely on calorie restriction and exercise.
Why Medical Weight Loss?
Conventional weight loss advice — eat less, move more — is not wrong. It is incomplete. For many patients, the reason they cannot lose weight or cannot keep it off has nothing to do with willpower or effort. It has to do with biology.
Hormonal imbalances (insulin resistance, leptin resistance, thyroid dysfunction) can make fat storage metabolically favored regardless of caloric intake. Appetite regulation disruptions (impaired GLP-1 signaling, ghrelin overproduction) create persistent hunger that overwhelms conscious control. Metabolic adaptation means that as you lose weight, your body actively fights to regain it by lowering metabolic rate, increasing appetite hormones, and reducing energy expenditure. Gut microbiome composition influences caloric extraction and fat storage signaling.
Medical weight loss addresses these underlying mechanisms. Instead of asking you to fight your biology harder, it changes the biological equation so that fat loss becomes physiologically supported rather than physiologically resisted.
At Peptide Therapy Raleigh, Dr. Vaidya integrates multiple evidence-based approaches into a unified weight management strategy. The goal is not just weight loss — it is sustainable metabolic health.
Your Medical Weight Loss Options
Semaglutide (GLP-1 Receptor Agonist)
How it works: Semaglutide mimics the GLP-1 hormone, reducing appetite, slowing gastric emptying, and improving insulin sensitivity. It acts on the hypothalamus to reduce hunger signals and increase satiety after meals.
Evidence: The STEP clinical trials demonstrated average weight loss of 15–17% of body weight over 68 weeks. This is among the most significant weight loss results achieved by any non-surgical intervention in clinical trials.
Administration: Weekly subcutaneous injection. Dosing starts low and titrates upward over several weeks based on tolerability.
Cost: Starting at $400/month. FDA status: FDA-approved for chronic weight management in adults with BMI 30+ or BMI 27+ with a weight-related comorbidity.
Best for: Patients seeking significant weight loss with robust clinical evidence, particularly those with appetite dysregulation as a primary driver.

How it works: Tirzepatide activates both GLP-1 and GIP (glucose-dependent insulinotropic polypeptide) receptors, potentially providing greater metabolic effects than GLP-1 activation alone.
Evidence: The SURMOUNT trials showed average weight loss of approximately 20–22% of body weight, exceeding semaglutide's clinical trial results.
Administration: Weekly subcutaneous injection with dose titration. FDA status: FDA-approved for weight management and type 2 diabetes.
Best for: Patients who may benefit from dual-mechanism metabolic support, or who have not achieved adequate results with GLP-1 monotherapy.
Metabolic Peptides (MOTS-C)
How it works: MOTS-C is a mitochondrial-derived peptide that research suggests activates the AMPK pathway, a central regulator of cellular energy metabolism. AMPK activation is associated with improved insulin sensitivity, enhanced fat oxidation, and better exercise adaptation.
Evidence: Preclinical research is promising; human clinical data is still developing.
Cost: Starting at $250/month. FDA status: Not FDA-approved. Used off-label under physician supervision.
Best for: Patients seeking metabolic optimization beyond appetite suppression, particularly those with insulin resistance or metabolic syndrome markers. Often used as a complement to GLP-1 therapy rather than a standalone weight loss intervention.
→ Learn more about MOTS-CNAD+ Therapy (Metabolic Support)
How it works: NAD+ supports mitochondrial energy production and metabolic enzyme function. Declining NAD+ levels are associated with metabolic dysfunction. Restoring NAD+ through IV infusion may support overall metabolic health as part of a comprehensive weight management program.
Evidence: Strong mechanistic basis; clinical evidence for weight loss specifically is limited. NAD+ is best understood as metabolic support rather than a primary weight loss intervention.
Cost: Starting at $200/session. FDA status: Not FDA-approved for weight management. Used off-label.
Best for: Patients addressing metabolic dysfunction as part of a broader protocol. Complements other interventions rather than replacing them.
→ Learn more about NAD+Functional Medicine Approach
How it works: Functional medicine weight loss identifies and addresses the root causes of weight resistance — gut health imbalances, hormonal dysfunction, chronic inflammation, food sensitivities, nutritional deficiencies, and stress-related metabolic disruption.
Approach: Comprehensive testing (hormone panels, gut microbiome analysis, food sensitivity panels, metabolic markers) followed by targeted interventions including dietary optimization, supplementation, lifestyle modification, and hormone balancing.
Best for: Patients with complex metabolic profiles, those who suspect underlying health issues are contributing to weight resistance, and patients who want to address root causes alongside pharmacological intervention.

How We Combine Approaches
The most effective medical weight loss often integrates multiple approaches rather than relying on a single intervention. Dr. Vaidya designs integrated protocols based on your specific metabolic profile:
GLP-1 Plus Metabolic Peptides
Semaglutide addresses appetite regulation and insulin sensitivity while MOTS-C supports cellular metabolic efficiency. The combination targets weight loss from both the demand side (reduced caloric intake through appetite suppression) and the supply side (improved metabolic utilization of stored energy).
GLP-1 Plus Functional Medicine
Semaglutide provides pharmacological weight loss support while functional medicine testing identifies and addresses contributing factors like thyroid dysfunction, gut dysbiosis, or cortisol dysregulation that may be limiting results or contributing to future regain.
Comprehensive Protocol
For patients with significant metabolic complexity — insulin resistance, hormonal imbalances, chronic inflammation, and appetite dysregulation — Dr. Vaidya may recommend GLP-1 therapy, metabolic peptide support, NAD+ for cellular health, and functional medicine root cause investigation working in concert.
Each approach has strengths, and the combination addresses more of the biological factors driving weight resistance than any single intervention alone.
What to Expect
Initial Consultation
Dr. Vaidya begins with a thorough evaluation: health history, previous weight loss attempts (what worked, what did not, and why), current medications, and specific goals. Comprehensive lab work is ordered — metabolic panel, hormone levels, insulin and glucose markers, thyroid function, inflammatory markers, and any additional testing indicated by your history.
Protocol Design
Based on your labs and clinical assessment, Dr. Vaidya recommends a specific combination of interventions. You will understand exactly what each component does, why it was selected for your situation, what the evidence base is, and what realistic outcomes to expect.
Ongoing Management
Weight loss is monitored through regular follow-ups with body composition tracking, lab work reassessment, dosing adjustments, and protocol modifications based on your response. The approach evolves as your body responds and your metabolic profile changes.
Frequently Asked Questions
Which weight loss option is best for me?
The best approach depends on your metabolic profile, not on general recommendations. Some patients need primarily appetite regulation (semaglutide or tirzepatide). Others need metabolic optimization (MOTS-C, NAD+). Many benefit from a combination. Dr. Vaidya determines the right approach based on your labs and clinical evaluation, not a default protocol.
Will I regain the weight after stopping medication?
Some weight regain is common after discontinuing GLP-1 medications, consistent with the understanding of obesity as a chronic metabolic condition. The goal of an integrated approach is to address as many contributing factors as possible — hormonal, metabolic, behavioral, nutritional — so that the biological environment supports weight maintenance even as pharmacological support is reduced.
Is medical weight loss safe?
FDA-approved medications (semaglutide, tirzepatide) have extensive safety data from large clinical trials. Off-label peptides are administered with appropriate monitoring. Dr. Vaidya screens for contraindications, monitors for side effects, and adjusts treatment based on your response. Every intervention carries some risk; the goal is to ensure benefits outweigh risks for your specific situation.
How much does medical weight loss cost in Raleigh?
Costs depend on the specific combination of interventions. Semaglutide starts at $400/month, MOTS-C at $250/month, and NAD+ at $200/session. Dr. Vaidya provides transparent pricing during your consultation so you can make an informed decision.
Can medical weight loss help if I have diabetes?
GLP-1 medications like semaglutide are also FDA-approved for type 2 diabetes management. They can address both blood sugar control and weight loss simultaneously. Dr. Vaidya coordinates with your endocrinologist or primary care physician to ensure safe, integrated care.
