Over the past two years, medications such as Ozempic (semaglutide) and other GLP-1 receptor agonists have become some of the most talked-about weight-loss treatments in the world. In South Africa, interest has surged, fuelled by social media, celebrity endorsements and the promise of rapid results.

For many people living with obesity or type 2 diabetes, these medications can be life-changing when prescribed and monitored by a qualified healthcare professional. However, there is a growing concern that many people are seeking these treatments as a “quick fix” without understanding the long-term commitment, potential risks or the importance of building healthy lifestyle habits alongside them.

Weight Loss Is More Than Just a Number on the Scale

Losing weight is only one part of improving your health. Your body also needs to maintain:

  • Lean muscle mass
  • Bone density
  • Strength and mobility
  • Cardiovascular fitness
  • Metabolic health

Without regular resistance training and proper nutrition, rapid weight loss can result in the loss of both fat and muscle. Muscle plays a critical role in supporting metabolism, improving insulin sensitivity, protecting joints and maintaining independence as we age.

Simply put, becoming lighter does not automatically mean becoming healthier.

Are Ozempic and Peptide Therapies Dangerous?

Not when they’re used appropriately. Medications such as semaglutide have been extensively researched and are approved for specific medical conditions. For suitable patients, they can improve blood sugar control, reduce appetite and support clinically significant weight loss.

The concern is not the medication itself; it’s how it’s being used. Increasingly, healthcare professionals and regulators are seeing:

  • Self-medication without medical supervision
  • Purchasing products online or through unofficial suppliers
  • Use by people who may not medically require treatment
  • Unrealistic expectations of permanent weight loss without lifestyle changes

In South Africa, the South African Health Products Regulatory Authority has repeatedly warned the public about counterfeit and unregistered semaglutide products being sold through social media and informal channels, highlighting that these products may be unsafe or contain incorrect ingredients.

The Hidden Risks of Chasing a Quick Fix

Many people focus only on the weight they lose while taking GLP-1 medications. Far fewer consider what happens afterwards. Research has shown that many individuals regain a significant proportion of the weight after stopping treatment if healthy eating habits and regular exercise haven’t become part of their lifestyle. Common side effects may include:

  • Nausea
  • Vomiting
  • Constipation
  • Diarrhoea
  • Fatigue

Although uncommon, more serious complications such as pancreatitis and gallbladder disease have also been reported and require medical attention.

This is why these medications should never be started or stopped without guidance from a qualified healthcare professional.

Why Exercise Still Matters

There is no injection that can replace the benefits of movement. Regular exercise helps to:

  • Preserve muscle during weight loss
  • Improve insulin sensitivity
  • Increase strength
  • Boost mental wellbeing
  • Support long-term weight maintenance

Resistance training is particularly important for anyone losing weight rapidly, as it helps protect lean muscle while encouraging the body to lose fat instead.

Nutrition Is the Foundation

Even the most effective medication cannot compensate for poor eating habits. A balanced, nutrient-rich diet provides:

  • Protein to preserve muscle
  • Fibre for gut health
  • Vitamins and minerals for recovery
  • Sustainable energy

Healthy nutrition also helps create lifelong habits that continue to benefit you long after any medication has been discontinued.

Sustainable Results Beat Quick Results

For some individuals, medications like Ozempic may form part of a medically supervised treatment plan. However, they should complement, not replacen a healthy diet, regular exercise, strength training and ongoing professional support.

Real transformation isn’t about finding the fastest solution. It’s about creating habits that improve your health today while protecting it for years to come.

If you’re considering any weight-loss medication, speak to your doctor first. The goal isn’t simply to lose weight; it’s to build a stronger, healthier body that can sustain those results for life.
