At Lifetime Performance Medicine in Los Gatos and the Bay Area, we go beyond calorie counting to uncover how your metabolism, hormones, and cellular health truly function. Our precision-based approach restores your body's ability to burn fat efficiently and sustain energy naturally. We combine advanced diagnostics, GLP-1 and peptide therapies, and lifestyle optimization to deliver sustainable, life-changing results.
Each GLP-1 program begins with an in-depth diagnostic analysis that maps your body’s hormonal and cellular performance. Guided by these insights, your physician-led care team creates an advanced protocol to amplify medication results, optimize metabolism, and restore sustained energy.
SEMAGLUTIDE OR TIRZEPATIDE
These advanced medications mimic your body's natural GLP-1 hormone to help regulate appetite and blood sugar. The result is smoother energy, fewer cravings, and a steady, predictable rate of fat loss. GLP-1 therapy retrains your metabolism to use energy efficiently – so you eat less without feeling deprived and keep the weight off once it's gone.
Benefits include:
• Significant, sustainable weight reduction (average 15-20% body weight)
• Reduced hunger and normalized appetite regulation
• Improved blood sugar control and insulin sensitivity
• Decreased cardiovascular risk factors
• Enhanced metabolic health and energy stability
• Better glycemic control for those with prediabetes or type 2 diabetes
MOTS-C, CJC-1295, IPAMORELIN, AOD-9604SEMAGLUTIDE OR TIRZEPATIDE
Peptides such as MOTS-C, CJC-1295 with Ipamorelin, and AOD-9604 work at the cellular and mitochondrial level to optimize how your body produces and utilizes energy. Unlike medications that primarily suppress appetite, these metabolic peptides enhance natural fat metabolism, preserve lean muscle, and elevate vitality. Together, they promote metabolic flexibility – your body’s ability to seamlessly shift between burning carbohydrates and fats for fuel – supporting sustainable weight loss, improved performance, and long-term metabolic health.
Benefits include:
• Enhanced fat metabolism and cellular energy production
• Improved exercise endurance and recovery
• Better insulin sensitivity and glucose regulation
• Increased mitochondrial efficiency
• Support for lean muscle preservation during weight loss
VITAMINS, MINERALS, AND AMINO ACIDs
Weight management isn't just about eating less – it's about ensuring your body has the nutrients it needs to function optimally. Through comprehensive testing, we identify deficiencies that may be sabotaging your metabolism, energy levels, and recovery.Our nutrient optimization protocols include targeted supplementation, IV nutrient therapy, and personalized dietary guidance to correct deficiencies and support healthy metabolic function.
Key focus areas:
• Vitamin D, B-complex, and magnesium for metabolic function
• Omega-3 fatty acids for inflammation reduction
• Amino acids for muscle preservation and recovery
• Micronutrient repletion for thyroid and hormonal balance
• IV nutrient therapy for rapid restoration and cellular support
MOVEMENT, SLEEP, AND STRESS MANAGEMENT
Sustainable weight loss requires more than medication – it requires lifestyle transformation. Our team provides ongoing coaching in the areas that matter most: nutrition habits, movement patterns, sleep optimization, and stress management.We work collaboratively to build realistic, personalized strategies that fit your life, your preferences, and your goals – creating changes you can maintain long after reaching your target weight.
Coaching includes:
• Personalized nutrition guidance (not restrictive dieting)
• Movement and exercise recommendations tailored to your fitness level
• Sleep optimization strategies for metabolic health
• Stress management techniques to reduce cortisol and emotional eating
• Accountability and support throughout your journey
GLP-1 (Glucagon-Like Peptide-1) is a naturally occurring hormone your body produces in response to eating. GLP-1 receptor agonists like Semaglutide and Tirzepatide are synthetic versions of this natural hormone, engineered to last much longer in your system. These medications mimic and amplify your body's natural GLP-1 response, providing sustained appetite regulation and metabolic benefits throughout the week.
Appetite Regulation: Reduces hunger signals and increases feelings of fullness, making it easier to eat appropriate portions without constant willpower battles
Blood Sugar Control: Helps your pancreas release insulin more effectively and reduces glucose production in the liver
Slowed Gastric Emptying: Food stays in your stomach longer, extending satisfaction and reducing the urge to snack
Reduced Cravings: Decreases food noise and obsessive thoughts about eating
Metabolic Reset: Helps restore your body's ability to burn fat efficiently
By addressing underlying metabolic dysfunction, GLP-1 therapy promotes natural, steady, sustainable weight loss – without constant hunger, willpower battles, or restrictive dieting.
GLP-1 therapy regulates appetite, curbs cravings, and helps you feel satisfied with smaller portions. Patients report fewer hunger spikes and less emotional or nighttime eating.
Optimized metabolism and stable blood sugar help eliminate crashes and brain fog. Patients report feeling alert, energized, and mentally clear – without caffeine or sugar.
Restoring metabolic balance improves insulin sensitivity, hormone regulation, and stress response. Patients often sleep better, feel better, and experience reduced cravings.

Have questions about our weight loss and metabolic programs? Below, we address the most common concerns about GLP-1 therapy, metabolic optimization, and how our innovative treatments help you achieve lasting results.
GLP-1 therapy may be right for you if you:
• Have a BMI of 27 or higher with weight-related health conditions (such as high blood pressure, type 2 diabetes, or high cholesterol)
• Have a BMI of 30 or higher
• Have struggled to lose weight or maintain weight loss through traditional diet and exercise
• Experience persistent hunger, cravings, or "food noise" that interferes with healthy eating
• Want a medically supervised approach to weight management
• Are committed to making lifestyle changes alongside medication
During your initial consultation, Dr. Nguyen will review your complete health history, current medications, and weight loss goals to determine if GLP-1 therapy is appropriate for you. Certain medical conditions may require additional evaluation or preclude GLP-1 use.
Both Semaglutide and Tirzepatide are highly effective GLP-1 receptor agonists, but they have some key differences:
Semaglutide (brand names include Ozempic® for diabetes, Wegovy® for weight loss):
• Activates GLP-1 receptors only
• Administered once weekly via subcutaneous injection
• Clinical trials show average weight loss of 15–17% of body weight
• Well-established safety profile with extensive research
• Excellent option for most patients starting GLP-1 therapy
Tirzepatide (brand name Mounjaro® for diabetes, Zepbound® for weight loss):
• Dual-action: activates both GLP-1 and GIP (glucose-dependent insulinotropic polypeptide) receptors
• Administered once weekly via subcutaneous injection
• Clinical trials show average weight loss of 20–22% of body weight
• May provide enhanced metabolic benefits due to dual mechanism
• Newer, more aggressive medication with promising results
Weight loss results vary based on individual factors, but clinical research and our patient outcomes show:
Semaglutide:
• Average of 15–17% total body weight over 68 weeks
• Example: A 200-pound person might lose 30–34 pounds
• Most significant weight loss occurs in the first 6 months
• Continued loss or maintenance with ongoing treatment
Tirzepatide:
• Average of 20–22% total body weight over 72 weeks
• Example: A 200-pound person might lose 40–44 pounds
• Progressive weight loss that continues over time
• Some patients achieve even greater results
GLP-1 Medication Side Effects
Most side effects are mild and temporary: nausea, decreased appetite, constipation, mild abdominal discomfort, fatigue, or headache.
How We Reduce Side Effects
Slow, personalized dosing, nutritional guidance, regular monitoring, and supportive therapies help your body adjust comfortably.
Serious Side Effects (Rare)
Pancreatitis, gallbladder issues, severe allergic reactions, vision changes (for diabetes), increased heart rate, or kidney problems.
When to Contact Us
Reach out immediately for severe abdominal pain, persistent vomiting, allergic reactions, vision changes, or any concerning symptoms.
Most patients benefit from ongoing treatment to maintain results.
GLP-1 regulates appetite and metabolism, so stopping too soon can lead to weight regain – similar to how chronic conditions often require continued medication.
Treatment Phases:
• Active Weight Loss (6–12 months): Gradual dose titration, steady fat loss, lifestyle coaching.
• Weight Stabilization (3–6 months): Maintain results, solidify healthy habits, adjust dosing.
• Long-Term Management (ongoing): Maintenance dosing, less frequent monitoring, continued lifestyle optimization; some patients may transition off under supervision.
Dr. Nguyen personalizes duration based on your progress, metabolic health, and lifestyle, ensuring a sustainable approach tailored to you.
At Lifetime Performance Medicine, we make treatment accessible for all patients: our team verifies coverage when appropriate, guides prior authorizations, and offers compounded Semaglutide or Tirzepatide from FDA-regulated pharmacies when not covered by insurance. Transparent pricing, flexible payment options, and comprehensive care (physician supervision, monitoring, nutrition guidance) are included.
Cost perspective:
While GLP-1 therapy requires financial investment, consider the long-term costs of obesity-related health conditions: type 2 diabetes, heart disease, joint replacement, sleep apnea treatment, and other complications. Many patients find that investing in metabolic health now prevents far greater medical expenses in the future.
We'll work with you to find the most cost-effective solution that fits your budget while delivering the results you're seeking.
Look no further for your wellness solution. Our practice combines advanced diagnostics with innovative treatments to address the health challenges that have resisted conventional approaches. Here, you'll find the personalized answers and transformative results you've been searching for.
