GLP-1s and the Fire Service: What They Do, What They Don't, and What to Ask Before Starting
A quick disclosure. I am not a physician or dietitian. These views are my own, and I have no financial conflicts of interest with weight-loss drug manufacturers.
It seems like GLP-1 drugs are everywhere right now. In the news, on social media, in the firehouse, your department's benefits conversations, and even holiday party chats.
What are GLP-1s?
GLP-1 agonists are medications that mimic a naturally occurring hormone. They act on appetite signaling in the brain, reduce hunger, slow gastric emptying, increase satiety, improve insulin secretion, suppress glucagon, and stabilize blood glucose. This is physiology, not magic.
To be clear, a stigma currently exists with these medications. Conversation around the firehouse table consistently demonstrates that GLP-1 use is labeled as "cheating" or a shortcut. That framing is not evidence-based, and holding traditional weight loss methods as inherently superior is a form of weight stigma.
Bottom line, though. The goal shouldn't just be weight loss. The goal should be improved health outcomes. Researchers such as Grant Tinsley, Ph.D., have clarified that in the literature. That mindset shift matters.
What GLP-1s do, and what they don't do
GLP-1s do change hunger signals. They are quite effective at that. People feel less hungry, get full faster, and often eat less without white-knuckling it. That's a real benefit for folks with loud and sometimes overwhelming hunger noise.
But the drugs don't rewire everything else that drives eating behavior.
They don't permanently change emotional eating patterns or resolve the relationship of trauma soothing with food. They don't undo years of learned associations between stress, comfort, and eating or rebuild identity structures around food and self-regulation, self-reward or even just the good old YOLO.
That distinction matters more than most people realize, because once you move past the food noise and appetite piece, you run straight into the stuff that actually determines long-term outcomes and whether those outcomes are a W or a L, because in this case the wins are about more than just losing weight.
Three practical benefits of GLP-1s in the fire service
Clinically meaningful weight loss improves movement efficiency and reduces load in turnout gear. That directly impacts job performance.
Improved glycemic control leads to more stable energy and fewer mid-shift crashes.
Reducing cardiometabolic risk addresses one of the leading causes of line-of-duty death.
Other benefits of GLP-1s for firefighters
There are also some downstream issues that deserve attention, especially in a fire service population.
Muscle loss with any weight-loss protocol (even the good old diet and exercise) is a documented risk. Particularly during rapid weight loss with surgeries, extreme calorie restriction, or drug-assisted modalities, meaningful losses in lean mass can occur, especially absent a structured training and nutrition plan. For a job that depends on strength, power, and load carriage, that shouldn't be a footnote.
And muscle is so important; it has been termed an insurance policy, especially in aging.
Insurance policy, what?
Indeed.
Muscle is a repository for glucose and is critical in maintaining independence in later life. (Think about those patients you pick up off the floor once per shift. Yes, they may have health issues, but more than likely they also have muscle issues or they wouldn't be falling and can't get up.)
Bone loss has also been documented in some studies, which could create problems for long-term health and wellness, particularly in females.
This is not a fringe issue either. U.S. spending on these medications increased from $13.66 billion in 2018 to $71.66 billion in 2023. That's an incredible amount of money being spent on weight loss, so being an informed consumer really matters.
The “so what, now what?!?” for GLP-1s
If you are considering GLP-1 use, there needs to be a more honest checklist than the one currently used in most settings.
What does your 5-year mortality risk look like? This one deserves a real hard look. If your risk of dying from a heart attack due to metabolic syndrome is high, that's a more pressing risk right now than worrying about how much muscle mass you'll have when you're 80. Weight loss is critical to make sure you make it to 80!
Do you have a baseline on muscle mass and bone density?
Is there a support system in place?
Is a registered dietitian and strength coach involved?
Is there a plan to maintain muscle?
Is there a plan for what happens when the medication is stopped?
Is there ongoing medical monitoring?
Is behavioral health being addressed?
Most people are not being walked through those questions, and for best results, drugs shouldn't ever be considered in isolation.
If GLP-1s are part of the plan, they need to be paired with aggressive strength and hypertrophy training. Not casual workouts, but structured, progressive training aligned with NSCA and ACSM guidelines.
Protein intake has to be intentional and sufficient. Behavioral health support matters. Whether that's CBT, mental performance coaching, or something similar, the underlying drivers of eating and fueling still need to be addressed. And a registered dietitian should be part of the process.
GLP-1s & the ‘tactical athlete’
There are also some tactical athlete-specific concerns that don't get enough attention.
Relative Energy Deficiency in Sport (RED-S) is a real risk when appetite is suppressed, but training demands stay high. In an academy or incumbent setting, that can show up as failure to perform up to expectations. Performance can drop, recovery may tank, and injuries could creep in.
And then there's the environment in which much of this weight loss prescription is happening. If your access point looks like a strip mall sign that says "Weight Loss, HRT, Tanning and Back Waxing," and that storefront is next to a nail salon and a joint that sells mattresses, that should give you pause.
That 'clinic' is probably not where firefighters should be getting guidance for something that directly impacts performance, health, and career longevity.
My stance on GLP-1s in the fire service
For me, this isn't about being pro or anti GLP-1. It is about safely losing weight (if that's your goal) while optimizing your health. None of this is anti-GLP-1. It's pro: doing weight loss carefully, correctly, and with full awareness of what the drug does and what it doesn't do.
If you're considering a GLP-1 drug, it's important to work with a provider who uses appropriate screening tools, provides medical oversight, and integrates training, nutrition, and behavior change.
When you're ready, here are three ways I can help you:
For departments that want to start with one session: I offer live and virtual 60-minute talks on topics including sleep, nutrition, mental health, injury risk, and training fundamentals. Virtual sessions can be repeated across all three shifts so your entire department is covered.
For departments ready for something more comprehensive: I offer a six-hour wellness training and consultation that combines talks, hands-on training sessions, and demonstrations, customized to what your department actually needs.
For departments that want an ongoing foundation: I offer a monthly virtual wellness series and a structured new recruit onboarding program designed to build health and performance habits from day one of a firefighter's career.
