GLP-1 receptor agonists like semaglutide (Ozempic, Wegovy) have quickly gained attention for their dramatic effects on weight loss and appetite control. But what happens when these medications enter the world of endurance sport? For triathletes and other athletes training long hours and pushing performance boundaries, the physiological impact of GLP-1 drugs could carry serious consequences. In this blog, we explore what GLP-1 medications are, how they work, and why their use in endurance athletes deserves careful consideration. Whether you're managing a medical condition or simply curious about emerging trends in performance and body composition, this article unpacks the current science, risks, and takeaways for the triathlon community.

What Are GLP-1 and GLP-1 Receptor Agonist Medications? 

Glucagon-like peptide-1 (GLP-1) is a hormone (an incretin) released from the gut after we eat. It helps regulate blood sugar by increasing insulin (when glucose is present) and reducing glucagon,...

Electrolyte drinks are everywhere right now.

They're popping up on podcasts, in influencer morning routines and on supermarket shelves.

But are they really necessary for everyone?

I recently spoke with the Australian Financial Review about this exact question for their article, “Electrolyte Drinks: The Simple Rule for When to Consume Them” (note: google the title to access the article if you don't have a subscription).

Here’s the key takeaway:

•  For most people, plain water is perfectly adequate for hydration. Electrolyte drinks are only beneficial when you’re exercising for long durations (think four hours or more) or sweating heavily in hot and humid conditions.

As I explained in the article, your sweat rate and sweat-sodium concentration are highly individual.

Some athletes lose much more sodium than others. If your training clothes often have white, crusty marks or you can wring out your top after a session, you might be a salty or heavy sweater.

That’s when it’s worth...

I’m thrilled to share some big news with you – Dietitian Approved has officially partnered with AusTriathlon as their trusted nutrition education partner.

This means triathletes across Australia will now have access to evidence-based, practical nutrition strategies designed to help them train harder, recover faster and perform at their best.

Why This Partnership Matters

Triathlon is a sport I love and live. Since lining up for my first race in 2009, I’ve been immersed in the community as an athlete, as Sports Dietitian for Triathlon Australia for six years, and now through the work we do every day at Dietitian Approved.

Over the years, I've seen many athletes train hard but leave their nutrition to chance. And that’s where the biggest performance gains are often hiding.

By teaming up with AusTriathlon, I can help more athletes stop winging it with their fuelling and start seeing the real benefits of a personalised, evidence-based approach to nutrition.

What Athletes Can Expect
