About Medical Weight Loss Therapy

Achieving significant and sustainable weight loss is often a challenge, especially for individuals with obesity or weight-related conditions or when spare time is limited due to life pressures.

Medical weight loss therapy offers a structured, doctor-supervised, and scientifically-proven approach to helping individuals lose weight safely and effectively.

Core Pillars of Medical Weight Loss Therapy

Medical weight loss involves a doctor-supervised, evidence-based approach to weight management, incorporating various medical, physical and mental health strategies.

Medical weight loss ensures that your journey is overseen by qualified healthcare professionals (eg: GP / Bariatric Physician) rather than just left up to you like many traditional weight loss programs.

Medical weight loss begins with a thorough medical assessment by your doctor, including laboratory tests and pathology screenings, providing a more accurate and detailed understanding of your unique health profile.

With detailed biometric data available, your doctor can create a highly personalised, custom treatment plan that considers and addresses underlying health factors such as metabolic rates, hormonal imbalances, and existing medical conditions, recognising their impact on weight gain and thus tailoring interventions accordingly.

Traditional weight loss programs tend to offer a simplistic one-size-fits-all solution.

Medical weight loss may involve the prescription of medications to address hormonal imbalances, metabolism regulation, or assist with appetite control, offering a more nuanced and targeted approach than traditional programs, as can treat the core of the issue.

Medical weight loss incorporates a holistic approach, addressing lifestyle factors, stress management, and mental health alongside dietary and exercise components, fostering long-term habits for sustained success.

Regular check-ins with your doctor allow for continuous monitoring of your progress and adjustments to your weight loss plan or medications as needed, ensuring ongoing adaptability to your body’s changing needs.

Medical weight loss programs provide education and tools to empower individuals to sustain their progress and adopt healthier habits, aiming for long-term success and overall well-being.

Ongoing appointments with your doctor can also be scheduled to ensure compliance and adjust and medical therapy as needed.

Prescription Medications

Prescription medications are often used as part of a comprehensive weight loss program, especially for individuals with a Body Mass Index (BMI) over 30 or those with obesity-related health issues such as diabetes or hypertension. These medications can aid in weight loss by suppressing appetite, increasing satiety, or inhibiting fat absorption.

Oral Medications

  • Orlistat (“Xenical”)
  • Phentermine (“Duromine”)
  • Naltrexone / Bupropion (“Contrave”)
  • Metformin (“Glucophage”)

Injection Medication

Saxenda is the only approved therapy in Australia. Other treatments may be suitable in an off-label manner, if appropriate.

  • Liraglutide (“Saxenda”)
  • Semaglutide (“Ozempic”)
  • Tirzepatide (“Mounjaro”)

Medical Nutrition Therapy

Medical Nutrition Therapy (MNT) involves working with a dietitian or nutritionist to develop a personalised diet plan. This approach focuses on balanced nutrition and behavioural changes to promote sustainable weight loss.

Low-Energy Diets (LED)

LEDs typically involve consuming 1,200 to 1,500 calories per day for women and 1,500 to 1,800 calories per day for men. In Australia, individuals following an LED under medical supervision can expect to lose about 0.5 to 1 kg per week, with a success rate of approximately 55% for maintaining weight loss over a year.

Very Low-Energy Diets (VLED)

VLEDs provide fewer than 800 calories per day and are usually prescribed for individuals with a BMI over 30. These diets often use meal replacements like shakes and soups. Australian studies show that VLEDs can result in rapid weight loss of 1.5 to 2.5 kg per week, with a success rate of about 60% for maintaining weight loss after one year, provided there is ongoing medical and nutritional support.

Behavioural and Psychological Support

Weight loss success is significantly influenced by behavioural and psychological factors. Incorporating behavioural therapy and psychological support can enhance the effectiveness of medical weight loss interventions.

CBT helps individuals identify and change negative thought patterns and behaviours related to eating and weight. It is often used in conjunction with other weight loss methods. In Australia, CBT has a success rate of about 65% for long-term weight management when combined with diet and exercise programs.

MI is a counselling approach that helps individuals resolve ambivalence about behaviour change and enhance their intrinsic motivation to lose weight. Studies in Australia show that MI can significantly improve adherence to weight loss programs, with a success rate of about 60%.

Bariatric Surgery

Bariatric surgery is considered for individuals with severe obesity (BMI over 40) or those with a BMI over 35 with obesity-related health problems. This type of surgery not only helps in weight loss but also improves or resolves many obesity-related conditions, such as type-2 diabetes, hypertension, and sleep apnoea.

Gastric Bypass (Roux-en-Y)

Gastric bypass surgery involves creating a small stomach pouch and rerouting the small intestine to this pouch, which reduces the amount of food you can eat and the absorption of nutrients. In Australia, patients typically lose 60-80% of their excess weight within two years post-surgery, with a success rate of about 80%. This surgery also shows significant improvements in obesity-related conditions.

Gastric Sleeve

Sleeve gastrectomy involves removing approximately 80% of the stomach, leaving a tube-like structure. This procedure restricts the amount of food that can be consumed and reduces the production of the hunger hormone ghrelin. Australian data indicates an excess weight loss of 50-70% within two years, with a success rate of around 75%. Like gastric bypass, it also helps improve obesity-related conditions.

Adjustable Gastric Band

This procedure involves placing an adjustable band around the upper part of the stomach to create a small stomach pouch. It limits food intake and promotes a feeling of fullness. In Australia, gastric banding has a success rate of about 50%, with patients losing 40-60% of their excess weight within two years. However, this procedure is less commonly performed due to the availability of more effective surgical options.
