Medically Supervised Protocol monitored by a physician

GLP-1 Therapy

GLP-1 therapy uses medications that mimic the hormone glucagon-like peptide-1 to help regulate blood sugar, reduce appetite, and slow gastric emptying, supporting sustainable weight loss and metabolic control. It’s typically prescribed as part of a medically supervised plan that may include nutrition, activity, and ongoing monitoring to optimize results and safety

15–20% Average body weight reduction in clinical trials

What is GLP-1 Therapy

The Science
Behind GLP-1

GLP-1 (glucagon-like peptide-1) is a naturally occurring gut hormone released after eating. It signals the brain to reduce hunger, slows gastric emptying to increase satiety, and regulates insulin secretion — all key levers for body weight and metabolic health.

 

GLP-1 receptor agonists like semaglutide and tirzepatide mimic and amplify this signal with sustained precision. In landmark clinical trials, participants lost an average of 15–20% of total body weight — results that far exceed traditional diet and exercise alone.

 

At Atlas BioFitness, GLP-1 therapy is never standalone. It is integrated into a medically supervised program that includes DEXA body composition tracking, nutritional guidance, and strength training — ensuring you lose fat, not muscle, and build the foundation for lasting metabolic health.

KEY FEATURES

Everything the Protocol Delivers

Neurological Appetite Suppression

GLP-1 agonists act directly on hypothalamic receptors, reducing hunger signals at the source. Cravings diminish — not through willpower, but through recalibrated neurobiology.

Sustained Fat Loss

Clinical trials show 15–20% total body weight loss over 68 weeks. Unlike crash diets, GLP-1 therapy produces steady, measurable fat reduction with minimal lean mass loss when paired with resistance training.

Metabolic & Glycemic Control

GLP-1 therapy improves insulin sensitivity, lowers fasting glucose, and reduces HbA1c — critical markers for long-term metabolic health and disease prevention regardless of diabetes status.

Cardiovascular Risk Reduction

Beyond weight loss, GLP-1 agonists are associated with significant reductions in major adverse cardiovascular events — lowering blood pressure, triglycerides, and inflammatory markers systemically.

DEXA-Tracked Body Composition

Every Atlas GLP-1 protocol includes baseline and interval DEXA scans. You see exactly what you’re losing — fat mass vs. lean mass — so we can optimize dosing, nutrition, and training in real time.

Medically Supervised Protocol

Your program is designed and monitored by a physician. Dosing is titrated over time to maximize efficacy and minimize side effects. Ongoing check-ins ensure your protocol adapts as your body changes.

Common Questions

Am I a candidate for GLP-1 therapy?

GLP-1 therapy is clinically indicated for adults with a BMI of 30 or above, or a BMI of 27 or above with a weight-related health condition such as type 2 diabetes, hypertension, or sleep apnea. At Atlas, we conduct a thorough intake evaluation to confirm suitability and rule out contraindications. A consultation with your Atlas clinician is the best way to determine if this protocol is right for you.

Semaglutide (Ozempic/Wegovy) is a GLP-1 receptor agonist that mimics the GLP-1 hormone. Tirzepatide (Mounjaro/Zepbound) is a dual agonist that activates both GLP-1 and GIP receptors, producing modestly greater average weight loss in head-to-head comparisons. Your Atlas physician will review your health history, goals, and any prior medication experience to recommend the most appropriate agent and starting dose.

The most common side effects are gastrointestinal — nausea, mild vomiting, constipation, or diarrhea — and are most pronounced during the dose escalation phase. These typically resolve as the body adjusts. Slow titration, dietary adjustments, and timing of injections all help minimize discomfort. Rare but serious risks include pancreatitis and, in patients with a personal or family history of thyroid cancer, thyroid tumors — your clinician will screen for these during intake.

Tirzepatide is administered by a small injection into your fat every week.  Semaglutide can also be administered by a weekly shot but recently a once a pill form was released.

It’s possible to regain some weight after stopping GLP-1 medications, especially if no long-term lifestyle changes are in place. These medications help regulate appetite and blood sugar, so when they’re discontinued, hunger levels and eating patterns may return to baseline.

However, weight regain isn’t guaranteed. Patients who maintain consistent habits—like balanced nutrition, regular exercise, and ongoing support—are far more likely to sustain their results. Many providers recommend a long-term plan to help you transition off the medication and protect your progress.

Most patients notice meaningful appetite suppression within the first 2–4 weeks. Measurable weight loss typically becomes evident at the 4–8 week mark as dosing escalates to a therapeutic level. The greatest body composition changes occur between months 3 and 6. DEXA scans at 12-week intervals give you a precise, data-driven view of your progress at every stage of the protocol.

Yes. Atlas offers bundled GLP-1 program packages that include monthly medication management, DEXA body composition scans at key intervals, nutritional coaching, and optional access to personal training and VO₂ Max testing. Financing is available up to $30,000. Ask at the front desk or during your consultation for current program pricing and bundle options.
