The Real Cost of Poor Nutrition

GLP-1 medications like Ozempic, Wegovy and Mounjaro are now firmly inside the triathlon conversation. Athletes are seeing dramatic weight loss results and wondering whether these drugs could help them perform better too.

But what actually happens when you combine appetite-suppressing medications with the demands of swimming, riding and running for hours every week?

In this episode, Advanced Sports Dietitian Taryn Richardson breaks down the science and practical realities of GLP-1 medications for endurance athletes. From muscle loss and gut issues to RED-S and race day fuelling disasters, this is the conversation triathletes need to hear before considering these medications.

In this episode, you’ll learn:


What GLP-1 medications actually do in the body


Why delayed gastric emptying can become a major issue for endurance athletes


The surprising amount of muscle mass that can be lost during rapid weight loss


How GLP-1 medications may increase the risk of RED-S in triathletes


Why hunger and thirst cues become unreliable on these medications


The key nutrition strategies to protect your performance if you’re taking a GLP-1


How protein and resistance training can help preserve lean muscle mass


Which foods give you the biggest micronutrient bang for buck when appetite is low


Why fuelling to a schedule becomes critical during long training sessions and racing


What WADA’s monitoring of GLP-1 medications means for athletes moving forward

Key Takeaways


Rapid weight loss can come with significant lean muscle loss if nutrition and strength training aren’t prioritised


Slower gastric emptying may increase the risk of gut distress during training and racing


Suppressed appetite can make chronic under-fuelling and RED-S much harder to detect


Triathletes taking GLP-1 medications need a very deliberate fuelling plan to maintain health and performance

Timestamps


00:00 – Why GLP-1 medications are suddenly everywhere in triathlon


01:47 – What GLP-1 medications actually do


03:00 – WADA monitoring and anti-doping implications


04:09 – The muscle mass problem triathletes need to understand


06:34 – Gut function, gastric emptying and fuelling challenges


08:50 – The hidden risk of RED-S and chronic under-fuelling


11:13 – Practical strategies for athletes using GLP-1 medications


12:35 – The most nutrient-dense foods when appetite is low


14:00 – Why fuelling to a schedule matters


16:00 – Final takeaways for triathletes

If you know a triathlete currently taking Ozempic or another GLP-1 medication, send them this episode. These conversations are happening quietly in squads all over the world, and athletes deserve practical, evidence-based guidance to protect both their health and performance.

About This Episode

Emma first joined the Triathlon Nutrition Academy Podcast all the way back in Episode 91 — Life of an Elite Australian Triathlete. Three years later she is back, and what a journey it has been. Mixed Team Relay World Champion. A new career with the NSW Fire Brigade. An acute ankle reconstruction that left her surgeon speechless at the speed of her recovery. And a deeply honest account of going from a decade of amenorrhea and RED-S to running 80km weeks and racing at her absolute best.

This episode is packed with gold for triathletes at every level — practical, personal and genuinely inspiring.


What You Will Learn
The four-pillar recovery protocol Emma used to come back eight weeks ahead of schedule
Exactly which supplements she used and why (collagen, creatine, fish oil, magnesium)
Why nutrition has to come first — before hyperbaric chambers or red light therapy mean anything
How Emma manages the mental side of injury, including her work with a sports psychologist
Her raw and honest account of ten years with amenorrhea, RED-S and the bone stress injuries that followed
The moment someone showed her the actual energy numbers — and everything clicked
How she went from 40km capped run weeks to 80km weeks and winning World Cups
Her decision to freeze her eggs after 10 years of amenorrhea affected her AMH and fertility
The big life plan: Fire Brigade, LA 2028 mixed relay gold and what comes after elite sport


Episode Timestamps
[00:00] Welcome back Emma — life update including Mixed Relay World Champs, the move back to Sydney and joining the NSW Fire Brigade
[03:47] The injury: acute posterior tibialis tendon rupture and full ankle reconstruction
[06:35] Milestones that blew the surgeon's mind: walking at four weeks, boot off and swimming normally by six weeks
[08:51] The four recovery pillars: rest, nutrition, hyperbaric oxygen and red light therapy
[10:13] Fuelling for recovery, not restriction: how Emma approached nutrition when training load dropped to near zero
[12:38] Hyperbaric oxygen therapy: four sessions a week and why the surgeon called it gold standard
[13:08] Red light therapy: passive, practical and something Emma will continue long-term
[16:46] Staying positive through injury: the 24-hour rule, drawing a line in the sand and working with a sports psychologist
[22:00] Three years of evolution: what has changed in nutrition, mindset and self-awareness
[24:05] What proactive and consistent fuelling actually looks like day to day for an elite athlete
[29:38] From tightrope to bridge: what adequate fuelling has done for Emma's injury resilience and training availability
[32:26] Body image, social media and why Emma deleted Strava from her phone
[38:03] RED-S in triathlon: the moment Emma saw her energy numbers and everything changed
[46:55] Getting her period back after 10 years of amenorrhea and the compounding effect of proper fuelling
[50:09] Egg freezing: making proactive decisions for fertility and life after elite sport
[54:30] Balancing elite sporting goals with long-term life goals
[58:08] The grand plan: Fire Brigade, LA Olympics mixed relay gold and what comes after


Key Takeaways
Nutrition first, always. Recovery nutrition is not about restriction. Carbs, fats and proteins all stay on board. Your body is doing serious work healing.
Big rocks before sprinkles. Hyperbaric and red light therapy are powerful tools — but only once sleep and fuelling foundations are locked in.
Proactive beats reactive. From booking psych appointments before she thought she would need them, to planning her nutrition before injury progressed — Emma stays ahead of problems.
RED-S is rampant and reversible. Emma went from chronic bone stress injuries and 10 years without a period to running 80km weeks and winning World Champs. The difference was fuelling adequately.
Honesty accelerates progress. The more open Emma was with her dietitian, physio, coach and family, the more effectively they could actually help her.
