Medical weight management is a physician-supervised approach to sustainable weight loss that goes far beyond calorie restriction and willpower. At LiveWell21, Dr. Charles Kamen combines advanced medications — specifically GLP-1 receptor agonists and GIP/GLP-1 receptor coagonists — with metabolic optimization, lab-based monitoring, and nutritional guidance to help patients achieve measurable, lasting results.
Traditional dieting fails because it ignores the biology of hunger. Your brain, gut, and metabolism work together to regulate appetite through complex hormonal signals. Modern weight management medications address these signals directly, reducing appetite, improving metabolic function, and preserving lean muscle mass during weight loss.
The clinical evidence is compelling. In the SUSTAIN trial, patients on semaglutide achieved 15-20% body weight reduction over 68 weeks. The SURMOUNT trials with tirzepatide showed even greater results — up to 22% body weight loss in some cohorts. These are not short-term results; they represent sustained metabolic change under physician guidance.
At LiveWell21, Dr. Kamen designs individualized weight management protocols based on your metabolic profile, health history, and weight loss goals. Every patient receives direct physician oversight from initial consultation through ongoing follow-up, with dosing adjusted based on your response and lab markers. This is concierge-level metabolic care, not a one-size-fits-all approach.
Dr. Kamen selects from a curated formulary of FDA-approved weight management medications and metabolic support peptides. Each medication or peptide is chosen for your specific metabolic profile and weight loss goals.
Primary use: GLP-1 receptor agonist for appetite regulation and metabolic optimization
Semaglutide is a once-weekly subcutaneous injection that activates GLP-1 receptors in the brain and gut, signaling satiety, slowing gastric emptying, and improving glucose metabolism. The SUSTAIN trial demonstrated that patients on semaglutide (1.0 mg weekly) achieved an average 15% body weight reduction compared to 2.6% in the placebo group over 68 weeks. Semaglutide also improves cardiovascular outcomes and reduces progression to type 2 diabetes. At LiveWell21, semaglutide is initiated at 0.25 mg weekly and titrated gradually to minimize side effects while maximizing efficacy.
Primary use: GIP/GLP-1 receptor coagonist for superior metabolic optimization
Tirzepatide is a newer agent that activates both GLP-1 and GIP receptors, producing more robust metabolic effects than GLP-1 agonists alone. The SURMOUNT trials showed that tirzepatide at 15 mg weekly produced average body weight reduction of 20-22%, with some patients achieving reductions exceeding 25%. Tirzepatide demonstrates superior glucose control, improved lipid profiles, and enhanced fat loss while preserving lean muscle mass. It is dosed weekly via subcutaneous injection and is typically initiated at 2.5 mg, titrated upward based on tolerance and response.
Primary use: Growth hormone optimization for body composition and metabolic support
This peptide combination enhances growth hormone secretion, which is critical for preserving lean muscle mass during weight loss. While semaglutide and tirzepatide reduce appetite and caloric intake, they can also reduce muscle mass if not balanced with adequate protein and growth hormone support. CJC-1295/Ipamorelin improves body composition by promoting fat oxidation while preserving or even increasing lean muscle tissue. This combination is often used alongside GLP-1 or GIP/GLP-1 medications to optimize the quality of weight loss.
Primary use: Metabolic health and gut healing support
BPC-157 accelerates intestinal healing and promotes healthy gut barrier function — critical for patients undergoing rapid weight loss. This peptide reduces gut inflammation, enhances nutrient absorption, and supports metabolic health during caloric restriction. BPC-157 also accelerates soft tissue healing, reducing exercise-related soreness during the increased physical activity that accompanies a weight loss program.
Primary use: Immune and metabolic support during weight loss
Rapid weight loss can temporarily suppress immune function due to caloric restriction. Thymosin Alpha-1 enhances T-cell maturation and immune surveillance, maintaining robust immune defense during weight loss. It also supports metabolic resilience and reduces infection risk in patients undergoing significant body composition changes.
Medical weight management at LiveWell21 is appropriate for adults who:
During your initial consultation, Dr. Kamen reviews comprehensive metabolic lab work, medical history, current medications, and your weight loss goals to determine whether medical weight management is appropriate and which medications will deliver the best results for your situation. Patients with certain conditions (uncontrolled thyroid disease, active malignancy, severe kidney or liver disease) may require additional evaluation or may not be candidates for certain medications.
Your first visit includes a detailed metabolic history, physical examination, and comprehensive lab panel. Dr. Kamen personally conducts every consultation — you will never be seen by a nurse practitioner or physician assistant for your initial evaluation. Labs include fasting glucose, insulin, HbA1c, lipid panel, liver and kidney function, thyroid hormones, and metabolic markers. This typically lasts 45-60 minutes and provides the foundation for your personalized protocol.
Based on your lab results, metabolic profile, and clinical assessment, Dr. Kamen designs a personalized weight management protocol. This includes your primary medication (semaglutide, tirzepatide, or another agent), dosing schedule, expected timeline, dietary recommendations, and any complementary peptides (such as CJC-1295/Ipamorelin) to optimize body composition. You receive clear instructions on medication administration, expected side effects, and what to expect at each dose escalation.
Medical weight management requires regular monitoring, not just initial prescription. Dr. Kamen schedules follow-up visits at 4-6 week intervals initially, with repeat labs at 8-12 week intervals. You report progress, side effects, and concerns, and Dr. Kamen adjusts your protocol based on objective data — weight loss percentage, lab marker changes, appetite reduction, energy levels, and metabolic markers. Dosing is optimized for your individual response, not a generic protocol.
Medication alone does not produce lasting weight loss; it works synergistically with nutrition and physical activity. Dr. Kamen provides evidence-based nutritional guidance emphasizing adequate protein intake (critical for preserving muscle mass during weight loss), whole foods, and sustainable eating patterns. He supports increased physical activity and helps manage any medication side effects that might interfere with exercise tolerance.
GLP-1 receptor agonists and GIP/GLP-1 coagonists are FDA-approved medications with extensive safety data from large clinical trials. When prescribed and monitored by a physician, they are safe and well-tolerated.
Common side effects are typically mild and transient, particularly during dose escalation:
Serious adverse effects are rare when medications are properly prescribed and monitored. Dr. Kamen screens all patients for contraindications, including personal or family history of medullary thyroid cancer or multiple endocrine neoplasia type 2 (both are absolute contraindications to GLP-1 and GIP/GLP-1 agents). All patients receive his direct cell phone number for urgent questions or concerns between appointments.

Book Your Free ConsultationYes. Semaglutide and tirzepatide are FDA-approved medications with extensive safety data from years of clinical use. The SUSTAIN and SURMOUNT trials followed patients for over a year, demonstrating sustained safety and efficacy. These medications are widely prescribed in the United States and internationally. Dr. Kamen monitors all patients with regular labs and follow-up visits to ensure safety and efficacy over time.
Weight loss medications are most effective when combined with sustained lifestyle changes — improved nutrition, regular physical activity, and healthy eating patterns. Many patients are able to maintain weight loss even after discontinuing medication, particularly if they have established new eating habits and activity levels. However, if you return to pre-treatment eating patterns, weight regain is possible. Dr. Kamen works with you to develop long-term strategies for maintaining your results.
GLP-1 agonists and tirzepatide reduce appetite and caloric intake, which can lead to some muscle loss if protein intake is inadequate. Dr. Kamen emphasizes adequate protein consumption (1.0-1.2 grams per kg of body weight) and often recommends complementary peptides like CJC-1295/Ipamorelin to preserve or enhance lean muscle mass during weight loss. Combined with progressive resistance training, patients typically lose primarily fat while maintaining or building muscle.
Most patients notice appetite reduction within the first 1-2 weeks after starting treatment. Weight loss typically becomes measurable within 4-6 weeks, with progressive results over 3-6 months. The rate of weight loss varies by individual, medication choice, starting weight, and lifestyle adherence. On average, patients lose 2-4 pounds per week, though some lose more quickly and others more gradually.
Yes. Medical weight management integrates well with peptide therapy, NAD+ infusions, IV therapy, hormone optimization, and other LiveWell21 services. In fact, complementary protocols often produce superior results. For example, CJC-1295/Ipamorelin combined with GLP-1 medication optimizes both fat loss and body composition. Dr. Kamen designs comprehensive protocols that may combine multiple modalities for synergistic results.

Most weight loss programs fail because they treat the symptom — excess weight — without addressing the underlying causes. Hormonal imbalances, metabolic dysfunction, chronic inflammation, and insulin resistance are the real drivers of stubborn weight gain, and no amount of calorie counting or cardio will fix them.
At Live Now Longevity, Dr. Charles Kamen approaches weight management as a medical condition, not a lifestyle failure. As a board-certified neurologist trained at Albert Einstein College of Medicine and Yale-New Haven Hospital, Dr. Kamen understands the complex neurological and hormonal pathways that regulate appetite, metabolism, and fat storage.
Medical weight management combines pharmaceutical-grade peptide therapy, comprehensive metabolic testing, and ongoing physician oversight to produce sustainable results. The average patient at Live Now Longevity achieves 15-22% body weight reduction within 6-12 months while improving metabolic health markers across the board.
Your program begins with a thorough evaluation that goes far beyond stepping on a scale. Dr. Kamen personally conducts a 45-60 minute consultation that includes:
This data-driven approach reveals the specific metabolic obstacles preventing weight loss. Many patients discover that hormonal imbalances, thyroid dysfunction, or insulin resistance — not lack of willpower — have been sabotaging their efforts.
Based on your lab results and clinical assessment, Dr. Kamen designs a multi-faceted weight management protocol. No two patients receive the same plan.
These medications are the most effective pharmaceutical tools for weight management available today. Semaglutide reduces appetite by mimicking the GLP-1 hormone that signals fullness to your brain. Tirzepatide adds GIP receptor activation for even greater metabolic effects.
Clinical trials demonstrate average weight loss of 15% with semaglutide and 22.5% with tirzepatide over 72 weeks. At Live Now Longevity, Dr. Kamen uses careful dose titration to minimize side effects while maximizing results.
Beyond GLP-1 medications, Dr. Kamen may prescribe complementary peptides to address specific aspects of your metabolic health:
CJC-1295/Ipamorelin: Stimulates natural growth hormone production to improve body composition, increase lean muscle mass, and enhance fat metabolism.
BPC-157: Supports gut health and reduces inflammation that can contribute to metabolic dysfunction and weight loss resistance.
NAD+ support: Restores cellular energy production and mitochondrial function, directly improving metabolic efficiency.
Medication alone is not a complete solution. Dr. Kamen provides evidence-based nutritional guidance tailored to your metabolic profile:
Dr. Kamen schedules follow-up appointments every 4-6 weeks during active weight loss. Each visit includes:
During the titration phase, appetite reduction begins gradually. Most patients notice decreased food cravings and earlier satiety within 2-3 weeks. Weight loss of 3-5 pounds is typical as your body adjusts to the medication.
As dosing reaches therapeutic levels, weight loss accelerates to 1-2 pounds per week. Patients commonly report improved energy, better sleep, and reduced joint pain as inflammation decreases.
Steady, consistent weight loss continues. Many patients reach 10-15% of starting body weight during this phase. Body composition shifts become visible.
Most patients approach their target weight. The focus shifts to maintenance: dose optimization, long-term lifestyle habits, and metabolic health preservation.
All medications are prescribed and monitored directly by Dr. Kamen. Common side effects include:
Serious side effects are rare with proper medical supervision. Dr. Kamen monitors for pancreatitis, gallbladder issues, and thyroid concerns at every visit.

Book Your Free ConsultationMost primary care physicians prescribe GLP-1 medications with minimal monitoring. At Live Now Longevity, you receive comprehensive metabolic testing, careful dose titration with regular check-ins, ongoing lab monitoring, and complementary therapies that address the root causes of metabolic dysfunction. You also see Dr. Kamen directly at every visit.
Research shows that patients who discontinue GLP-1 medications without a transition plan regain approximately two-thirds of lost weight within a year. This is why Dr. Kamen emphasizes lifestyle modification alongside medication and works with patients on a gradual, monitored transition plan.
Yes. Many patients benefit from combining weight management with NAD+ therapy for cellular energy, peptide therapy for body composition, or IV therapy for nutritional support. Dr. Kamen designs integrated protocols that address multiple health goals simultaneously.
Live Now Longevity offers telehealth consultations for Nevada residents. Initial lab work can be completed at any Quest or Labcorp location, and medications ship directly to your home.
Previous GLP-1 treatment failure often results from inadequate dosing, lack of monitoring, or failure to address underlying metabolic issues. Dr. Kamen evaluates why previous attempts did not work and designs a protocol that addresses those specific obstacles.
