GLP medications are everywhere right now.
Patients are hearing about semaglutide, tirzepatide, Ozempic, Wegovy, Mounjaro, and Zepbound from social media, friends, gyms, med spas, online clinics, and probably even strangers on the internet. And while these medications can be incredibly effective, they are also some of the most misunderstood tools in wellness right now.
At The Retreat Wellness + Aesthetics, wedo not look at GLPs as magic shots or trendy shortcuts. We look at them aspowerful medical tools that can absolutely help the right patient when they areused the right way. That means understanding the difference between the types,knowing when to choose one over another, and avoiding the common mistakes thatare giving these medications such a bad reputation.
What is the difference between GLP-1, GLP-2, and GLP-3medications?
The first thing patients need tounderstand is that these drugs are not all the same.
GLP-1
Semaglutideis the most common GLP-1. Brand names include Ozempic, Wegovy, and Rybelsus.It works mainly by acting on the GLP-1 receptor, helping slow gastric emptying,regulate appetite, and improve how the body handles glucagon after meals. Insimple terms, it helps people eat less and feel full longer.
GLP-2
Tirzepatide is often referred to here as the next step up because it works on both the GLP-1 receptor and the GIP receptor. Brand names include Mounjaro and Zepbound. That added GIP activity can improve insulin sensitivity and nutrient handling, which is one reason tirzepatide may work especially well inpatients with more metabolic dysfunction.
GLP-3
Then there is retatrutide, whichis still under investigation and is not FDA approved. It works on threereceptors, adding a glucagon receptor effect on top of GLP-1 and GIPactivity. That can increase energy expenditure in addition to appetite control,which is why it is getting so much attention. But because it is not FDAapproved yet, it is not something your practice uses.
When should someone use semaglutide vs tirzepatide?
This is where a lot of people get misled.
Many patients assume stronger automatically means better. It does not.
At The Retreat, many patients still startwith semaglutide, partly because it is more affordable and partlybecause many people simply do not need something stronger. Tirzepatide may be abetter fit when the patient has more significant insulin resistance, orwhen higher doses of semaglutide start bringing on side effects that maketirzepatide the smoother option.
That is an important distinction.
The goal is not to jump to the strongestdrug possible.
The goal is to use the lowest effective dose that helps the patient lose fat, preserve muscle, and improve metabolic health safely.
Myth #1: GLPs make you lose muscle
Not automatically.
This is one of the most common fears patients have, and it is also one of the most misunderstood. GLPs do not selectively destroy muscle. What happens is that the medication suppresses appetite, and if the patient is not intentionally maintaining enough protein, enough resistance training, and enough overall nutritional support, they may lose muscle because they are under-eating and losing weight too quickly.
That is not the drug “ruining” muscle.
That is poor program design.
This is exactly why body compositionmatters more than the number on the scale.
Myth #2: You have to stay on GLPs forever
Not necessarily.
Patients who use GLPs like a crash tool,make no lifestyle changes, lose weight too quickly, and then stop abruptly aremuch more likely to regain weight. But that does not mean everyone has to stayon them forever. When the medication is titrated up slowly, muscle mass ispreserved, habits improve, and the patient is eventually tapered appropriately,long-term success is much more realistic.
Some patients may stay on a microdose or low maintenance dose for broader metabolic benefits, including insulin sensitivity and possibly some cardiovascular or cognitive support. But that isvery different from saying the drug only works if you are on it forever.
Myth #3: Everyone gets terrible side effects
They should not.
The reason so many people think thesedrugs are brutal is because they are often being used incorrectly. Manypatients are started too high, titrated too fast, or given poor instructionsaround food, protein, hydration, and fiber. That is when you see nausea,vomiting, feeling miserable, and people swearing they will never touch themedication again.
In your practice, patients are startedlow and doses are only increased about every four weeks, which gives the bodytime to adjust. That slower, smarter approach is a huge reason side effectstend to be far less dramatic.
Myth #4: Higher doses always work better
They do not.
This is one of the biggest mistakes patients and low-quality programs make. The goal is not to race to max dose. Infact, many patients never need to get anywhere near the maximum dose to be successful. Your transcript explains that most semaglutide patients often do well well below the maximum, and many need less, not more, as their body composition improves.
Why?
Because once patients start building or preserving muscle, improving insulin sensitivity, and reducing body fat, their metabolism changes. Pushing the dose higher than necessary only increases the risk of side effects and poor-quality weight loss.
Myth #5: Using a GLP is cheating
This one deserves to die already.
If using a GLP the right way is cheating, then using any medication to improve health would also be cheating. That logic falls apart immediately. What patients are often really criticizing is not the medication itself, but the misuse of the medication.
Using semaglutide or tirzepatide while still lifting, prioritizing protein, improving nutrition, preserving muscle, and working on long-term habits is not cheating. It is using a medical tool intelligently.
A good comparison from the episode isyour own experience: despite already working out consistently and eating well,you were plateaued for years until microdosed semaglutide helped you finallybreak through while maintaining or slightly gaining muscle and losing fat. Thatis not laziness. That is strategy.
Why body composition matters more than scale weight
This might be the most important point inthe whole conversation.
Patients get obsessed with the number onthe scale, but that number alone can be misleading. If someone loses fat whilemaintaining or gaining muscle, the scale may barely move, or may even go upslightly, while their body is improving dramatically. That is why your practicefocuses on InBody scans and body composition, not just weight.
The goal is not just smaller.
The goal is healthier.
The bottom line
GLP medications can be incredible toolsfor weight loss, insulin resistance, and metabolic health when they are usedproperly. But they are not magic, and they are not meant to replace reallifestyle change.
At The Retreat, the goal is not toovermedicate, overdose, or chase the strongest option possible. The goal is touse the right medication, at the right dose, for the right patient, whileprotecting muscle, improving body composition, and actually making the processhealthy and sustainable.
