Medical weight loss in Los Gatos
Physician-supervised weight loss using GLP-1 medications (Semaglutide, Tirzepatide) paired with body composition tracking, comprehensive metabolic testing, and hormonal evaluation. Built to lose fat while preserving lean muscle, prescribed and monitored by Dr. Richard Nguyen in Los Gatos.

You Don't Need A Membership To Start
Weight loss medication at Lifetime stands on its own. No membership, no long commitment, just physician-supervised care from Dr. Nguyen and Morgan Carmean.
You get the same clinical standard our members receive: a real evaluation, real monitoring, and a prescription only when it's the right call for you. Membership exists for patients who want the wider program, ongoing optimization, hormone care, and longevity labs. If that fits you, we'll say so. If it doesn't, the medication path works completely on its own.

Why most weight loss programs fail
Most weight loss programs treat the body as a calorie equation. Eat less, move more, repeat. That model works for some people, fails most, and ignores the hormonal and metabolic drivers that determine what your body actually does with what you eat.
At Lifetime, medical weight loss addresses those underlying drivers directly: insulin sensitivity, appetite regulation, leptin signaling, thyroid function, sleep, stress, and the GLP-1 pathway that controls how full you feel and how efficiently you metabolize glucose. Then we use prescription medications and protocols that work with those systems, not against them.
The GLP-1 approach
GLP-1 medications (glucagon-like peptide-1) work by mimicking the natural hormone that regulates blood sugar, slows gastric emptying, and reduces appetite. This isn't appetite suppression through stimulation. It's restoring a signal your body uses to know when it's eaten enough.

The medications we prescribe include Semaglutide (sold under brand names Ozempic and Wegovy) and Tirzepatide (Mounjaro and Zepbound). The newest generation of GLP-1 medications offers improved efficacy and patient outcomes compared to earlier formulations. Results across patients are striking: significant and sustained weight reduction, improved insulin sensitivity, better blood sugar control, lower cardiovascular risk markers, and improved metabolic health overall.
Why supervised medical weight loss is different
Plenty of clinics in the Bay Area will write a GLP-1 prescription without much else. That's not what we do. Medical weight loss at Lifetime is paired with:
Body composition tracking via DEXA scans (so we know we're losing fat, not muscle)
Metabolic testing (fasting insulin, glucose, A1C, lipid panel, ApoB)
Hormonal evaluation (because thyroid, cortisol, and sex hormones all affect weight)
Ongoing physician oversight by Dr. Nguyen
Nutritional and resistance training guidance to preserve lean mass
Adjustments based on your individual response over time

For some patients with significant weight management challenges or specific medical situations, surgical options may be more appropriate than medication-based approaches. Dr. Richard Nguyen is also a board-certified general surgeon with over twenty years of experience and Vanderbilt fellowship training in minimally invasive and bariatric surgery. He performs gastric sleeve, gastric bypass, and other bariatric procedures at Lifetime Surgical.
Medical weight loss is appropriate for someone who has tried conventional approaches without sustainable results, who has metabolic markers that suggest underlying dysregulation (elevated A1C, insulin resistance, stubborn visceral fat), or who wants to lose weight while protecting muscle mass and metabolic health.
It's not a cosmetic shortcut and we don't treat it as one. Your physician evaluates whether the medications make sense for your situation, your medical history, and your goals before any prescription is issued.

Answers To Common Questions
We believe in transparency. Here are answers to the most common questions about our approach and programs.
Without the metabolic and lifestyle changes that should accompany the medications, weight regain after stopping is common. That's why we layer in body composition tracking, resistance training guidance, and metabolic optimization, so the changes are sustainable when you taper or stop.
Current data supports long-term use under medical supervision for appropriate patients. Side effects are typically mild and manageable. Your physician monitors you throughout treatment.
Coverage varies. Some GLP-1 medications are covered for specific medical indications (type 2 diabetes, high BMI). For wellness or weight optimization without those indications, coverage is less common, but HSA and FSA funds are typically eligible.
No membership required. We offer weight loss medication as a standalone service, fully physician supervised and monitored. Membership simply unlocks extras like hormone optimization and longevity labs for anyone who wants the complete program.
