Weight-loss drug dilemma

Exercise New Zealand is part of a world-first global call for urgent action on obesity medications.

With nearly three billion adults worldwide currently overweight or living with obesity, a number that is projected to rise significantly in the coming decade, the potential of GLP-1 therapies is a significant clinical advancement, says a joint statement from the World Obesity Federation, the Health & Fitness Association, AUSactive, Exercise New Zealand, Fitness Industry Council of Canada, and ukactive. However, it warns that medication alone is not enough.

Without integration with physical activity, nutrition, and ongoing lifestyle support, there is a risk of poorer long-term outcomes, including loss of muscle mass, reduced functional capacity, and increased pressure on already stretched health systems.

Exercise New Zealand CEO Richard Beddie says this moment presents a critical opportunity to get implementation right.

“GLP-1 therapies can be a powerful tool in addressing obesity. However, without strength training and broader lifestyle support, we risk worse long-term health outcomes and increased pressure on the health system. This is our opportunity to build an approach that is safe, effective, and truly holistic.”

CEO of World Obesity Federation Johanna Ralston adds that “GLP-1 therapies are an important advance in obesity care, but they cannot succeed in isolation. People with obesity demand and deserve access to good nutrition and physical activity support and advice, to support lasting rather than short-term health improvements. Governments must ensure these treatments
are embedded within comprehensive, person-centred systems of care.”

The global statement calls on governments, policymakers, and health leaders to:

Embed obesity medications within integrated care models that include funded access to physical activity and nutrition support
Continue investing in prevention and community-based programmes
Ensure equitable access to both treatment and support services
Measure success beyond weight, including long-term health and functional outcomes

Exercise New Zealand says Aotearoa is uniquely positioned to lead in this space, with a strong network of exercise facilities, qualified exercise professionals, and community-based programmes already supporting New Zealanders across the country.

“Physical activity should not be an optional add-on, it is fundamental to long-term success,” says Richard. “We must act now to ensure these medications are implemented in a way that improves not only short-term weight-loss outcomes, but overall health and well-being.”
