Australians using popular weight loss medications are being issued a stark new health warning: failing to combine the drugs with regular exercise could lead to significant muscle and bone deterioration.
The Hidden Risk of Rapid Weight Loss
Fresh research is sounding the alarm over serious potential side effects for the estimated 2 per cent of Australians currently using prescription drugs like Ozempic for weight management. The concern centres on the loss of lean muscle mass and bone density if the pharmaceutical treatment is not paired with physical activity.
Ken Griffin, CEO of the industry body AUSactive, highlighted the risks during a recent television interview. "These drugs can be really great if you're using them for weight loss," Griffin stated. "The challenge is that because of how they work, it means that if you're not using weight-bearing exercise as part of your program, you're going to actually not just lose fat, you're actually going to lose muscle, which is going to leave you weaker and frailer."
He further warned that the impact extends to skeletal health, potentially leading to weaker bones over time.
An Urgent Call for Integrated Treatment Plans
The warning comes at a critical juncture, as the number of Australians accessing these medications is expected to rise significantly. This anticipated increase is driven by a federal government move to subsidise the drugs through the Pharmaceutical Benefits Scheme (PBS) in the coming months, making them more affordable and accessible.
In response, experts are making an urgent call for regular exercise to be included as a non-negotiable component of any weight loss drug regimen. Research from Deakin University provides clear guidance, recommending that users undertake structured, weight-bearing exercise at least two to three times per week to counteract the adverse effects.
"What we want to do is make sure everyone who's considering using these is getting the full benefits by making sure they don't have health issues later on in life," Griffin emphasised, underscoring the preventative goal of the advice.
Practical Steps for Safe and Effective Use
While the message is clear, the path to implementation is designed to be practical. Experts stress that joining a gym is not a mandatory requirement. Instead, the focus is on safe and effective movement.
Key recommendations for users include:
- Seek professional guidance initially: Working with an accredited exercise professional ensures safety and helps tailor a program to individual needs and capabilities.
- Prioritise weight-bearing activities: This includes exercises like strength training, walking, jogging, or body-weight exercises that force muscles and bones to work against gravity.
- Integrate activity consistently: Building exercise into a weekly routine is essential for long-term protection against muscle and bone loss.
The overarching message from health and fitness authorities is one of proactive management. As powerful new tools for weight loss become mainstream, a holistic approach combining medication with physical activity is vital to safeguard long-term health and strength.
