Weight-Loss Medications & Muscle Loss: What Every Woman Needs to Know
The conversation around GLP-1 weight-loss medications is growing rapidly in Australia, and while these medications can deliver significant results on the scale, there’s an important piece of the puzzle many people aren’t hearing about.
Here’s a clear breakdown of the latest Exercise Sport Science Australia (ESSA) media release and what it means for your health.

The Rise of GLP-1 Medications
Weight-loss medications like GLP-1s are becoming increasingly common, with even broader access expected soon through oral versions. With around two-thirds of Australian adults classified as overweight or obese, it’s no surprise these medications are being embraced as a powerful tool in managing weight and chronic disease.
But rapid weight loss isn’t always as straightforward as it seems.
The Hidden Risk: Muscle Loss
Research shows that 15–40% of weight lost on these medications may come from lean tissue - including skeletal muscle.
This is a big deal.
Muscle isn’t just about how your body looks — it plays a critical role in:
Strength and physical function
Metabolic health
Bone support
Long-term independence as you age
Losing muscle too quickly, especially without the right support, can increase the risk of:
Frailty
Falls
Reduced mobility
Declining overall health
Why This Matters More in Perimenopause
For women in perimenopause and beyond, maintaining muscle becomes even more important.
Hormonal changes already make it easier to lose muscle and harder to maintain strength. When you combine that with rapid weight loss from medication — without proper guidance — it can accelerate the very changes we’re trying to prevent.
The Gap in the System
Right now, there is no requirement in Australia for patients to receive exercise or nutrition support when prescribed these medications.
That means many people are:
Losing weight without preserving muscle
Not being guided on protein intake
Missing structured exercise support
Potentially setting themselves up for long-term health issues
Experts are now calling for mandatory referrals to Accredited Exercise Physiologists when these medications are prescribed — to ensure patients are properly supported.
The Key Message: Exercise Is Essential, Not Optional
One of the strongest takeaways from this media release is this:
Exercise is not a “nice to have” when using weight-loss medications — it is a critical part of your treatment.
The right program can help you:
Preserve and build lean muscle
Support fat loss (not just weight loss)
Maintain strength and bone health
Improve long-term metabolic outcomes
What This Means for You
If you’re considering or currently using GLP-1 medications, the goal shouldn’t just be weight loss, it should be body composition change and long-term health.
That means:
Prioritising adequate protein intake
Following a structured, progressive exercise plan
Supporting your body through the process — not just shrinking it
