Weight Loss Injectables
I’ve been meaning to write this for a while now, and with more questions coming up in clinic, it feels overdue. You’ve probably heard about the latest weight-loss drugs like Wegovy and Ozempic, which have been a major health story in 2024. These injections mimic a natural hormone (GLP-1) that helps control appetite and blood sugar, tricking the body into feeling full and slowing digestion.
Do they work? Yes, they can be effective for weight loss, and in the right circumstances, with proper support, they may have a place. But before you consider them, let’s talk about some downsides:
Side Effects: Studies show nausea is reported as a common side effect, and I’ve observed gut issues in many cases (constipation, diarrhoea, vomiting and bloating).
Nutrient Deficiencies: Consuming less food can lead to inadequate nutrient intake. In my experience, this may result in low levels of essential vitamins and protein, which can contribute to fatigue, weakened immunity, and other health issues.
Food Enjoyment: Many report feeling apathetic or even revolted by foods they once enjoyed.
Cost and Sustainability: Benefits only last while the drug is taken, and studies show most weight is regained within a year of stopping.
Unknown Long-Term Effects: There’s limited understanding of what prolonged use might do.
The root of the issue lies in the prevalence of ultra-processed foods in Western diets. Medications alone can’t fix this—they risk creating dependency while ignoring the need for lasting dietary and lifestyle changes.
Building healthy habits is the foundation of long-term well-being. Medications can play a role, but they should never replace the power of good nutrition, movement, and professional guidance. Nutritional therapists specialise in creating sustainable plans tailored to individuals, helping to pave the way for healthier futures.
Don’t beat yourself up—losing weight is not just about willpower. It's not simply about choosing to eat less; it’s about understanding and managing the underlying factors. Concepts like Set Point Theory explain how our bodies resist weight changes, which makes lasting loss particularly challenging. Dr. Andrew Jenkinson’s books, Why We Eat (Too Much) and How to Eat (And Still Lose Weight), dive into this in detail - well worth a read.
I understand the appeal—if weight has always been a struggle, this might seem like a golden ticket. My takeaway advice is:
Don’t underestimate what diet and lifestyle changes can do. Small, consistent changes can be more effective than drastic measures.
If you choose to try a weight-loss drug, ensure you’re supported by a knowledgeable professional.
