Medical Weight Loss Treatments: A Personalized, Evidence-Based Approach in Lewisville, TX

At Health Express Clinics in Lewisville, we understand that losing weight—and keeping it off—is complex. As a board-certified family physician, I’ve seen how excess weight affects every aspect of a patient’s life: physical health, mental well-being, energy levels, and confidence.

We take a holistic, science-backed approach to weight loss, combining prescription medications like Semaglutide, Tirzepatide, Phentermine, Qsymia, and Contrave with lifestyle modifications, nutritional guidance, and exercise support to help our patients make lasting changes.

Why Weight Loss Requires a Medical Strategy

Weight gain isn’t simply a matter of willpower—hormones, metabolism, sleep, stress, and genetics all play roles. That’s why many people struggle despite eating well or exercising regularly.

“When evaluating weight loss patients, I always consider underlying metabolic conditions, sleep apnea, thyroid health, and emotional eating patterns. The right treatment begins with the right diagnosis.”
— Dr. Harveer Parmar, MD

Our program emphasizes root-cause evaluation, not just calorie-counting. And because no two patients are the same, we customize the plan to fit your goals, medical history, and lifestyle.

Top 5 Questions Patients Ask About Weight Loss Treatments

1. Is medication necessary for weight loss?

Not always—but for many patients with BMI >27 with comorbidities or BMI >30, medications can amplify the effects of diet and exercise and help overcome metabolic resistance. They’re tools, not shortcuts.

We use FDA-approved medications only when clinically indicated and always combine them with behavioral and nutritional strategies.

2. What are Semaglutide and Tirzepatide, and how do they work?

  • hese medications mimic gut hormones (GLP-1 and GIP) that:

    • Reduce appetite and cravings
    • Slow gastric emptying
    • Improve insulin sensitivity

    Medication Highlights:

    • Semaglutide (Wegovy, Ozempic)
      • Weekly injection
      • Average weight loss: 15–18% of body weight over 68 weeks
      • Also lowers blood sugar and cardiovascular risk in diabetic patients
    • Tirzepatide (Mounjaro)
      • Dual GLP-1/GIP agonist
      • Average weight loss: 22.5% in clinical trials
      • Emerging as the most effective agent in its class

    “These medications have changed the game. For the first time, we have tools that regulate hunger in a physiologic, sustainable way—especially for those with metabolic syndrome or insulin resistance.”
    — Dr. Harveer Parmar, MD

3. What are the most common side effects?

  • Most side effects are gastrointestinal and improve over time:

    • Nausea
    • Constipation or diarrhea
    • Reduced appetite
    • Injection site soreness

    We use dose escalation protocols to minimize side effects and screen for contraindications (e.g., history of medullary thyroid cancer or pancreatitis).

4. Are older weight loss meds like Phentermine still effective?

  • Yes—in certain patients. Phentermine, Qsymia (phentermine/topiramate), and Contrave (naltrexone/bupropion) are oral medications that help suppress appetite, improve satiety, or reduce emotional eating.

    We frequently use them:

    • In patients not eligible for injections
    • As bridge therapy while waiting for insurance approvals
    • In combination with lifestyle coaching

    All medication use is closely monitored for side effects, blood pressure, and heart rate changes.

5. Can I lose weight with lifestyle changes alone?

Yes—and for some, lifestyle is all they need. But for many people with stubborn weight or hormonal drivers, medications can help accelerate results and maintain long-term success.

Our approach always begins with:

  • Realistic nutrition (not starvation or fad diets)
  • Daily movement tailored to fitness level
  • Sleep optimization
  • Mindful eating and stress management

“Medications can help reset your biology, but sustainable change happens when we build healthier habits alongside them.”
— Dr. Harveer Parmar, MD

Exercises for Weight Loss: What Works?

We don’t believe in one-size-fits-all fitness. Instead, we recommend movement strategies that fit your lifestyle and build consistency.

Evidence-Based Recommendations:

  • Aerobic exercise (walking, cycling, swimming): 150–300 minutes/week
  • Resistance training: 2–3 sessions/week to preserve lean muscle
  • HIIT: Time-efficient and effective for fat loss
  • NEAT (Non-Exercise Activity Thermogenesis): Increase daily steps, take stairs, reduce sitting time

“In Lewisville, we often recommend walking at parks like Central Park or using home workouts during hot summers. Movement should be accessible and enjoyable—not a punishment.”
— Dr. Harveer Parmar, MD

Misconceptions About Weight Loss

❌ “Weight loss is just about willpower.”
✔️ Weight regulation involves complex hormonal systems, not just motivation.

❌ “Medications are unsafe or a crutch.”
✔️ When prescribed responsibly, modern weight loss meds are safe, effective, and FDA-approved.

❌ “I just need to eat less and move more.”
✔️ True to a point—but without addressing metabolism, inflammation, sleep, or stress, results may stall.

When to Consider a Specialist or Second Opinion

We refer to endocrinologists or bariatric specialists when:

  • Underlying hormonal disorders are suspected (e.g., Cushing’s, pituitary)
  • A patient qualifies for bariatric surgery (BMI >40 or >35 with comorbidities)
  • Previous severe side effects from medications
  • Mental health or eating disorder components complicate treatment

“Our job as primary care providers is to recognize when a patient needs more intensive support. But for many, we are the right starting point.”
— Dr. Harveer Parmar, MD
