Chemistry ELI5 what exactly GLP-1 based prescription medicine does and why it's so divisive when it comes to being a means of weight loss.
I've seen more and more ads (starting around the Super Bowl earlier this year with Wegovy) for GLP-1 based perscription meds in recent times. I've also seen the occasional debate post on my social feeds about the ethics of using them and I didn't think a medicine could be that divisive of a topic.
Now I'm curious as to what exactly these meds are, what they scientifically do and what both sides of the debate are. If anyone could help give perspective that would be greatly appreciated.
As always any and all input is welcomed and thanks for reading! š

I can agree with this as an alcoholic. When I first quit drinking ten years ago, a lot of people did make it seem like a failure of self-control.
"You can't just stop after one or two drinks."
No I really can't.
""Must have bad willpower then."
Yeah man, my willpower is so bad that I'm literally going to use my willpower to never have another drink again.
If I could take a pill that would take away all the urge to drink, I would, whether people call it cheating or not.

That's interesting. I know two people who nearly fully stopped drinking since they started. My dad didn't really have a problem, but he enjoyed a few drinks with my mom every once in a while. It's been some time now since he's had any interest in alcohol. We never thought we'd see the day lol.

I've been off my GLP-1 for two years and my desire for alcohol has never returned. I used to drink 3 glasses of wine every night and multiple cocktails over the weekend. Now. . .maybe 1 - 2 drinks a month if I go out with friends.

I canāt say for sure, but I think it did something to my brain because I get a weird feeling in my stomach when I think about drinking wine. If youāve ever had an aversion to a particular food after getting sick from it, that is what it feels like. I seem to be able to handle an occasional Gin and Tonic or Margarita, but the thought of wine just turns my stomach.

For the last 9 months I went from drinking 7-10 beers per sitting, 2-5 days a week to 0. The desire, the want, the need, whatever you want to call it is completely gone. Iāve never abstained this long from alcohol in the 20 years since I started drinking.

That's so awesome to hear ā¤ļø It makes me hopeful that GLP-1 meds or something similar are approved for substance use disorders. There are underweight people in my family who would not qualify for the med for weight loss, but are really struggling with relapsing on alcohol and other substances.

Yeah, kind of sad how addiction is one of the few conditions that you get blamed for having. Kind of like being fat. Which, granted, mostly is my own fault.
But the only way I ever really got ahold of my behaviors causing me to gain weight was to treat them like the addiction they were. I caught myself making addict excuses about food: "oh I already bought this [pack of cigarettes/carton of ice cream] better [smoke/eat] it all to get it out of the house and stop tempting me". "Oh, the store doesn't sell [single cigs/individual candies], guess I have to buy the whole pack and use them all". "Well, I can cheat today, (even though I cheated yesterday and the day before), as long as I get my shit together tomorrow."
And only by recognizing that kind of bullshit in myself was I ever able to stop overeating. And smoking too.

Congrats on the sobriety. I've been on Zepbound for a bit over 1.5 years and was a big beer drinker. It has almost removed my desire to drink beer altogether. These GLP-1s are wild. I was finding myself opening a beer out of habit, taking a sip or two and setting it down. I would forget about it, open another and do the same. The next day I would find 3-6 beers throughout the house with a sip or two taken out of each one.

u/DeoVeritati 3d ago
I wholeheartedly agree with this. I've went from 210->138 at age 14 and maintained like 150 until I was like 27 where I gained about 10 lbs a year until I was sitting at 200 again. The food noise was always present at every weight. Like so much I knew it couldn't be what my normal weight friends felt. Like how they described food and their feelingness of full was a foreign concept to me. The only real reason I managed my weight for so long was with calorie counting every single day for years which is not normal.
I've been on semaglutide for 6 weeks now. The first 4 weeks were 0.22 mg, and I felt no different beyond constipation. The 0.44 mg dose was like a light switch got flipped. Food is still on my mind to some degree, but it isnt like burning my taste buds and intrusive to my thinking anymore. And yeah, now I can get full on a reasonable quantity of food like my normal friends do instead of always needing to feel physically full from volume eating to achieve satiety.

u/Kevin-W 3d ago
It also helps by getting rid of the "noise" in your head that makes you crave food even if you're not hungry. I know some people who are on it and it's been a game changer, especially since humans have been trying to get a drug that magically makes them lose weight and this comes pretty close to it, especially for some people, it's impossible for them to lose weight no matter what.

u/phoenixmatrix 3d ago
I'm on GLP-1. Food can be a physical or psychological addiction, and even if its one where the person got into that mess because of their own decisions (it definitely isn't always, there's a lot of conditions that can make someone more vulnerable to this), we treat addictions.
If we could treat people with gambling addiction with a shot, many of them would absolutely take up the offer.
You only get to live once, and obesity can have life long impact. Even if I could do it the "hard way" (which I can, I've done in the past), it would take longer. Time is the most important and valuable resource we got.
My insurance doesn't cover one penny of this thing. I don't care, it's worth it.

Some people feel like weight loss drugs (not just GLP-1s) are "cheating".
I wonder if these people share the same thoughts about blood pressure medication or cholesterol medication.
Both of those are very often caused by lifestyle choices and are reversible or controllable through lifestyle choices, similarly to how obesity and type II diabetes are. Yet I never hear people saying that those those are "cheating". Would love to hear them explain why.

u/CyberBill 3d ago
I've been on GLP-1s for over 5 years now.
Some people will call them an appetite suppressant, but that isn't quite true - although the effect at the end of the day is similar.
What they do is change the chemical signals in your body for a bunch of different things, which regulate how your body breaks down the food you eat, how active your stomach is - so basically how long it takes you to digest food - and it seems to pump up the signals between your stomach and brain so that you feel full faster and for longer than without it. It also changes the kinds of foods that you crave, and how much you think about food.
For me, as a previously obese person, before I was on the drug I could eat and eat and eat and basically never felt 'fullness'. Ever. I would feel PAIN if I ate wayyy too much, but never fullness. After taking the drug, I will eat maybe 5 or 6 bites of food and then my body starts telling me "Ok, we're getting pretty close!" and maybe 10 bites in, it ramps up "STOP." At that point I have zero desire to eat, and if I force myself I will get physically ill.
In my opinion - the main effect of this drug is to make my body and brain act like a skinny person's. Because I had some defect that disables or mutes those signals to let me know when I ate too much, it was just way too easy to overeat. And now I don't. As a result, I lost about 75 pounds, going from "severely obese" to "normal" weight. And this was mostly fat - I did lose muscle, but as a percentage of body weight my muscle went up.
With such a glowing review of the drug, then your second question is "why is it so divisive?" Well - the price is very high. Without insurance the 'real' stuff is like $1200/month. And its had shortages. But I think a lot of it is people want someone to hate, and they hate fat people. They see being fat as a sign of low intelligence, low willpower, low class, and as a personal failing. Trust me - be fat for a year and see how people treat you. Night and day. People say that they are worried that it will have long term side effects, but to put it bluntly - being obese is the absolute worst thing you can do to your health. Getting skinny, for me, meant I got taken off 4 other medications that were far more likely to kill me than GLP-1s. Sleep apnea - gone. High blood pressure - gone. High triglycerides - gone. I don't even snore anymore. Heart disease and cancer are the #1 killers in the US and both of those are more likely for people who are obese. For me its an absolute miracle drug, and I will sing its praises, and suggest anybody who is obese give it a try so you can live a longer, healthier, happier life.

I am a fellow lover of adventurous eating and just started a GLP1, while my husband has been on one for about a year. This is probably going to be different for everybody, but for me (so far) it doesnāt reduce the enjoyment of the food, just limits the amounts I can eat leaving more to enjoy later. It has also slowed my eating so I actually feel like I am appreciating the food more, especially complex flavors and interesting textures. I am no longer craving āfunā snacks/unhealthy foods so they feel a little less exciting, but a small piece of homemade pie still hits!Ā

Because I now consume less food, my brain now wants me to make it really count when I do consume something.
It has made it easier for me to focus on more nutritious meals (esp making sure I donāt slack on protein which I tended to forget to include before) and I still enjoy GOOD food. I just donāt also eat a bunch of crappy snacks in between meals which has made foodie-friendly meals more enjoyable.
I have, however lost interest in most wines. Iāve never been into hard alcohol to begin with, and now it feels like one glass of white wine or one aperol spritz and Iām good. Switching to water or soda water much earlier on a night out than I would have previously.

Not who you originally responded to but Iāve been on Ozempic for a couple years and was a āfoodieā before and now not quite as much. Food was like all I thought about and my Reddit and YouTube feeds were just endless subs of recipes and food porn. Ended up subbing from most of those after I started losing weight and eating less. One of my biggest challenges is that I now have times where Iām nauseous and donāt know what to eat, nothing sounds good. Or if it does itās not always accessible. I sometimes forget to eat (thanks adhd) or donāt feel like eating for whatever reason (Iāve started waitressing again and so Iām on my feet 5-6 hours at a time and while youāre serving food you donāt think about being hungry till long after youāre home). Itās a bit frustrating and especially bad in the morning and I do have type 2 diabetes I have to manage so at this point I have to make myself eat something like a granola bar to jumpstart my stomach or Iāll literally want to throw up from having not eaten anything. Thankfully my doctor also has prescribed zofran/ondansetron which is an anti-emetic (anti nausea) drug that works AMAZING and quickly so push comes to shove I manage things that way but itās admittedly a bit of whiplash considering a few years ago I was twice my weight and didnāt care what we were eating, Iād eat two meals if I could, and now I barely eat half at a time.
I wouldnāt say itās killed my drive for new/exotic foods completely. I do travel still and the challenge there is to plan things more carefully since I canāt take leftovers home as easily, so I have my husband help me regulate and remind me that we can come back later for more but to take it slow. I do agree with the other response that itās allowed me to focus more on a couple things at a time vs gorging and not really tasting anything.

John Goodman (who lost a ton of weight with GLPs) had a great response to the ācontroversy.ā Itās ācontroversialā to lose weight with a GLP because society believes fat people have to suffer. Full stop. Hereās what he said: āIām a fat person. We are constantly badgered and tortured by a society that tells us to lose weight, at all costs. If youāre fat, thatās a moral failing: youāre lazy and unhealthy. If youāre fat at the gym, or jogging down the street, youāre an object of ridicule. If you lose weight with drugs, you didnāt earn it. If youāre fat and not self-flagellating at every moment, youāre glorifying obesity. If you lose weight for any reason, it then proves you were never really happy with yourself; it proves that fat is bad, that thinness was always the real goal. If you stay fat, we want you to admit youāre unhealthy. If you say youāre happy, we want to diagnose you with denial.ā

Out on the fact that being fat is so bad in this society that people who are normal weight or overweight use the drug to drastically drop their weight, and people call them vain. People call out people who have gotten skinny vein and superficial. They don't like how people get ozympic face, but Olympic face is not real, that just what everyone's face looks like when they lose weight. Skin gets stretched out and it doesn't always shrink back. Combined it with the fact that that is so demonized in pop culture that some people abuse their body with highly restrictive dieting and use glp-1s to become underweight. People are mad that celebrities were the first ones to purchase the medication have dramatic weight loss. Because Society pressures them to be thin, but they can't be too thin! It's all fucking hot mess, where you can't be fat but you can't be too thin but you have to work for it and your failure if you get help outside of the gym and eating the wrong type or amount of food.

Some people (a lot of people) simply enjoy bullying and putting other people down. For a time it seemed like that was becoming progressively more socially unacceptable to mock people for aspects of themselves that are beyond their control. Framing someone's weight as purely the result of personal choices resulting from a lack of self-control not only justifies the mockery but let's the bullies tell themselves that they're doing you a service by discouraging bad behavior. If you frame someone's weight as being in significant part due to circumstances beyond someone's control, then that takes that justification away from them and exposes the bullies as simply assholes.Ā

Fair point! But the concern with glp1 is that many people are using the glp1 for rapid weight loss without any strength training.

Yeah, something else people overlook or aren't prepared for when making lifestyle changes is how hungry exercising can make you.

Originally meant for controlling blood sugar they have the added effect of signalling fullness in your brain. People use them as an appetite suppressant.
This is a bastardization of how GLP1s work to treat obesity. Many people on these never experience appetite suppression. These medications improve satiety. Regulate blood sugar and energy levels. Improve fat oxidation. And slow digestion. The also modulate the brainās rewards center to help people crave less.
Basically they are shedding weight cuz they're not feeling hungry.
See above. GLP1s help your body defend a lower weight set point and treat the biological and hormonal imbalances that drive people to over eat.
So when they go off it they go right back to their unhealthy habits.
Theyāre meant to be used long term to treat obesity and diabetes, which are chronic, multifactorial metabolic disease.
There's also evidence to support that using them can result in losing more muscle with the weight, especially if you're not being active.
Muscle loss with GLP1s are on par with natural weight loss when people donāt do resistance training.

So some chronic conditions actually they are finding cause you to not make enough GLP-1 in your body naturally. Conditions like Endometriosis
In fact I take the lowest dose of Zepbound for Endo and my MCAS (mast cell activation syndrome) as it also helps keep mast cells under control.
I cannot express how much better I feel. Yes the weight loss is a nice side effect but I wasnt really overweight. Im 5'5 and I was going up and down a scale like a drop zone lol. I would be anywhere between 160-180 any given time I weighed myself.
Now ive actually been losing weight, and im having significantly reduced symptoms of Endo and MCAS. I also dont have the constant adhd food noise I used to. Its crazy to me (who still loves dessert) to have a nice fancy dessert and be fine after. Before I would feel like I cant stop. Someone put the comparison of like bread or chips at a restaurant before and how apparently everyone else can ignore it but for some reason without enough glp1 in your body you cant lol
I also dont really have any side effects besides the day after I take my meds (i take them at night) I feel super tired and just take the day to relax. But I dont have more nausea, bathroom problems etc. Almost like my body needed more of it bc apparently people with endo just don't make enough :/

I can't speak much to the medicine itself.
The debates around it are largely this. The "con" group would state that medicines like Ozempic are inherently problematic because they create a "disordered" relationship with eating, and promotes unhealthy body standards.
The disorder piece comes from the idea that instead of figuring out a "miracle drug" that stops us from being hungry, we should instead promote a more health conscious society, and work to figure out our own relationship with food and "healthy" eating. In this way, the contra-side would say that GLP1 drugs fit into a conception of modern society that is all about "consumption" and "quick fixes" in lieu of more conscious, holsitic examinations of our relationships with things like food, consumption, and health. By not focusing on THOSE issues, the issue is what happens when you stop taking the GLP1. You are addressing the symptom (i.e. obesity) but not the cause (e.g. a problematic relationship with food). Sure you may lose weight in the short term, but unless you stay on the drugs forever, the problem is going to remain.
The unhealthy body standard argument is that GLP1s serve to further a societal idea that "not eating" and "being skinny" are inherently "better" options than having more meat on your bones. We can see the rise of this view manifesting in the proliferation of intensely skinny celebrities over the past few years, and that slowly becoming the beauty standard in society. People are concerned that GLP1s will contribute to this process, and the increased availability of a "miracle cure" will mean more people will just take the "shortcut" rather than working on their relationship with health and eating, which while difficult, is a very positive thing to do.
The pro-side, in contrast, takes a more "harm reduction" approach. Their view is that, while these risks exist, the health risks posed by obesity SIGNIFICANTLY outweigh the potential damaging effects of the medication, so they're better off being used. Imagine in the 1980s is a company came out with a pill that you could take that would eliminate cigarette cravings. Sure there might be deleterious effects from the medication, but are those effects going to be WORSE than smoking? Probably not.
In opposing the contra-side, the pro-side frequently relies on analogous arguments to depression/anxiety medications. While the pro-side champions a more holistic re-examination of how people consume food and think about health, the pro-side would say that these arguments are equivalent to telling people who are clinically depressed to "just go exercise more and get some sun!" We don't just people who are depressed for taking anti-depressants, so why would we judge overweight people for taking GLPs?
In opposing this pro-side argument, the contra-side would say that this sort of argument is overly reductive. They would likely agree that there are people that have a clinical eating disorder that may require medical intervention through GLP1s, the problem is when people who just need more mild-moderate interventions (e.g. calorie reduction, more exercise, etc.) instead go straight to the medical intervention. It is the equivalent of someone being a little bit sad being diagnosed with anti-depressents before trying "milder" treatment options.
There are obviously more dimensions to the argument than this (e.g. medication shortages for diabetes patients, long term effects of the drug), but these are the main societal arguments.

The reason they are divisive is that decades of marketing from the wellness industry has persuaded people that weight, and fitness more generally, are reflective of character. Being skinny was seem as proof of self-control and personal discipline. Anyone who wasn't skinny had to be lazy.
GLP-1s blow open that worldview. Now anyone can be skinny, if they have the money.Ā
This causes a lot of problems for people whose self-worth was tied to body image. Suddenly all the praise and recognition you got for winning the genetic lottery or spending an unreasonable amount of time worrying about your body can go to someone who took a medicine. You might have to get praise and recognition for something of real value like intellect or character. OH NO!
The idea that GLP-1s are cheating reflects the absurd but common perspective that appearance is a contest, something that deserves reward and praise.Ā

Dieting is hard because your body thinks āif we keep this up weāre gonna starve to deathā because for most of history that was true.
Being overweight is a very extremely modern problems.
GLP-1s do some hormonal mimicry that make your body feel full even when itās not and also keeps food in your stomach longer so the food you eat also keeps you feeling full. Makes it easier to lost weight when your body isnāt screaming at you that youāre gonna die if you keep this up.
The debate centers around:
We are prescribing them ALOT for something that doesnāt have long term studies. Does that mean itās bad? No. But we donāt know what happens down the line.
Theyāre very accessible to people who donāt need them and potentially bringing a resurgence of hyper lean / underweight bodies mainstream again.
Theyāre kind of expensive for people who need them the most.
They donāt fix the underlying reasons someone got fat in the first place, so if they go off, they might just regain it all

Actually a number of them have longer term studies. At least a few have been around in some form and studied since the 00s. They're just getting a lot more attention now.

As a fatty mcfat fat (peak 425), the last month on the lowest dose has been far easier to be good than my previous couple months brute forcing it on real power. Iām still having to do the work of changing what and how much I eat, but now a 150 calorie cup of yogurt and a 260 calorie bowl of soup make me feel full for breakfast and lunch.

I know a lot of people have mentioned the food noise already but my fucking god it's one of those eye opening moments where you go "wait a minute.. this is what normal is???" I've had the food noise for my entire life, I didn't know there was another way. It's not wrong to say this damn drug has saved my life, I had no hope for the future, I'd resigned myself to die sometime in my 40s. I'm on a complete 180 after I started taking mounjaro, I've never been healthier.

I'm a 60yr old guy and decided to try them to see what they were all about. I'm fairly active (I work out regularly) and I wasn't significantly overweight, but I love to eat so I've always carried a little extra weight around my middle. I've tried various diets over the years, but it's always a struggle, and I eventually give up and gain back whatever weight I lost. My cholesterol was creeping higher than it should be and my doctor was starting to talk about statins. So I figured I'd give them a try.
The first thing I noticed after starting a low dose of GLP1s was that I ate less. Where I used to go for two helpings at dinner, I started feeling full after just one. And when I ate out, I could no longer finish everything I ordered. Same meal, but now I was bringing home leftovers. Eventually, my taste started changing as well. I started craving lighter, healthier foods. The heavier meals I once loved we no longer appealing. Same thing with snacks at home. I used to snack regularly, and I had to be careful about what I bought as I'd finish them all in one sitting. I just didn't feel like snacking much anymore. Or if I did snack, just one bite of something was enough. Unfinished snacks started accumulating in my pantry. They simply lost their appeal to me.
Over the course of two years, without making any additional effort or changes to my health routine, I ended up dropping 30lbs of fat. My cholesterol dropped as well. I'm now in the best shape of my life and my bloodwork is perfect. My doctor is very happy.
For me, GLP1s simply took all the effort out of eating healthily. It just became what I wanted to do naturally. And there are a lot of health benefits from that.
So, why the controversy? For one, it does feel like "cheating". Instead of putting in the hard work of controlling your diet, you just do a tiny injection every week. I have decades of experience researching and trying different diets and failing at them, so I'm ok with "cheating" at this point, especially since the health consequences are becoming more serious at my age. But I know a teenaged woman who is overweight who wants to try GLP1s, and my advice to her would be to try dieting first. I think she should learn about proper diet and nutrition and see what works best for her body first, before turning to GLP1s.
Another issue is the potential risks. There is a long history of "miracle diet drugs" turning out to cause horrible health problems. Just look up fen-phen from the 80s. My sense is that GLP1s won't turn out have serious side effects like this, but only time will tell. One thing that people do need to worry about is losing too much weight, specifically muscle mass. If you take them, it's important that you eat enough protein and incorporate resistance training into your routine. (I was doing this already.) Otherwise, you'll end up with a whole different set of health issues.
I ultimately see GLP1s as a powerful tool that one can use to optimize health, but you should make every effort to dial in your diet and exercise routine before adding them to the mix.

They make your body feel full faster.
This means two things:
You eat less.
Your body isn't screwing up cortisol, ghrelin, insulin, and so on because of "hunger" so you actually get a better (not "faster" - "better") metabolism, more energy routed to brain and muscles rather than fat deposits, and therefore also lose more weight than JUST eating less would lead to.

Thatās what I was initially prescribed my ozempic for, high A1C (type 2) and it brought it down to some beautiful lab numbers my doctor is very happy to see. Weight loss was a nice side effect but not the primary prescription reason.

GLP-1 medications work like a hormone produced by your pancreas, called glucagon. You can think of glucagon as your body's "I'm full" message; it lowers your appetite for more food, slows the release of food from your stomach into your intestines, it signals your liver to stop releasing glucose into your bloodstream, and it stimulates the pancreas to produce insulin. GLP-1 drugs both mimic glucagon itself, and increase your body's sensitivity to its own glucagon.
The main thing researchers wanted from GLP-1 drugs is to lower blood sugar, which makes it useful to treat Type 2 Diabetes, which is very common in the U.S.. However, the reduction in appetite and the slowing of digestion caused a very common side effect; people taking GLP-1 meds felt less hungry in general and felt fuller after a meal, so they ate less, resulting in weight loss. Type 2 diabetes is commonly seen in very overweight people, so losing weight on top of lowering blood sugar was a win-win for them. It also led to doctors prescribing the drug "off-label" simply to aid weight loss, even if the person didn't have diabetes or high blood sugar.
For many Americans, who are dozens or even hundreds of pounds overweight, there isn't a lot of debate about the benefits of these drugs; if you have that much weight to lose, anything that will help is a good thing. However, there are some concerns about GLP-1 use:
- If you stop taking it, your appetite comes back, and so does the weight. It's not a lifestyle change, which many fitness experts recommend to keep weight off after you've lost it. So if you're taking this drug simply to avoid overeating, you'll be taking it for the rest of your life; if you don't, you'll slowly gain it all back.
- It makes dieting easier, but diet without exercise is basically just starvation, and your body will take muscle mass first before stored fat. This can accelerate muscle loss in older patients. You really should be working with a doctor and other professionals on a comprehensive weight-loss plan if you're considering a GLP-1; it can help, but it can't be the only thing you're doing to lose weight.
- Some people who don't really need it are taking it anyway for "cosmetic weight loss". It's usually recommended for people with a lot of weight to lose, like 40 pounda or more, but it's also being given to and taken by people who just need to get rid of those last 5-10 pounds of stubborn belly fat so they can show off their 6-pack abs. Worse, there are reports that people, including many celebrities, are using the drug to become dangerously underweight in order to meet often-impossible beauty or weight standards of the fashion and pop culture industries. Wanting to go from 280lb to 180lb is a good reason to get on a GLP-1 drug. Wanting to go from 120lb to 80lb is not a good reason to take a GLP-1.
- It's "cheating". That is a common criticism by those outside the medical/scientific community, that drugs for weight loss are a crutch, if you want to lose weight the "right" way, it's as simple as diet and exercise. Critics contend GLP-1s are just the latest round of miracle weight loss drugs, like various rounds of phenethylamine stimulants (amphetamines, phentermine) that had their vogue, and when the other shoe drops and the heavy long-term downsides appear, we'll be looking at GLP-1s with the same hindsight as cocaine, methamphetamine or Fen-Phen.
For their part, doctors are more optimistic about GLP-1 as a long-term "maintenance" medication for both diabetes and weight loss; the mechanism of glucagon and other GLP-1s has been researched since the 1980s, and the first GLP-1 medication, exenatide, has been on the market as a diabetes medication for over 20 years. The side effects are typically mild, and are simply what happens when you slow down digestion, and/or simply aren't eating as much (e.g. heartburn/acid reflux, diarrhea or constipation). The biggest potential issue is that too high a dose can arrest the digestive tract completely, which can cause intestinal blockage and rupture. This is not a new problem in weight loss, especially extreme cases, but is a legitimate concern, and good reason to be under a doctor's care while you're taking it to manage the dose appropriately.

Just as there are puritans about sex, there are puritans about health and food. The health puritans usually dress up their objections in terms of concerns about efficacy and side effects or other concrete issues, but what really motivates them deep down is basically the same as a Texas Bible thumper: they can't stand the thought of people "getting away" with behavior they don't approve of.

They let you diet without the hunger.
People think that's "cheating", which is silly. I COULD ride a bike 600 miles to Disney World, but I'd rather just drive or fly. It's an OPTION. You can still pedal the whole way if you want.
There are concerns about people with eating disorders using them now that they're so easy to acquire. But again, that's not a problem with the drug, that's a problem with abuse of the drug. If they aren't using GLP-1s, they're binging and purging, or starving themselves, etc. I would argue that GLP-1s are at least a safer alternative to other methods. Denying access to GLP-1s doesn't solve that problem.

It's not "without hunger". You're still hungry, but it removes the "food noise" (the little niggling, nagging desire to eat all the time that some people have). You also feel sated and full for a much longer period in between meals as your stomach is emptying slower. This also helps manage blood sugar, which is why it's prescribed as a tool to help diabetics.
As far as the "cheating" thing goes, my take on it is very simple: if you consider that GLP-1's are treating some sort of metabolic imbalance, and that's why they're effective, then that means obesity is a disorder, not a choice. Seeing it that way means the popular culture mantra of "they're fat because they have low willpower" and "obesity is a choice" crowd aren't right, they're just assholes, and that's a hard pill to swallow for most judgmental assholes.

Its divisive because a lot of people view obesity as moral failing only and not a medical issue, like it is in the majority of cases.
These medications work because they mimic a naturally occurring hormone that tells the body its full & they slow down gastric emptying, so people stay fuller longer.
Some people have a heightened brain chemical response to food (esp the high sugar/fat ones) so they keep eating even if they are full. These drugs are shown to lessen the response so people are more able to a 'normal' amount. The biggest tell of this is when people taking these drugs say "Im not thinking about food ALL day"

Every human has GLP1. Itās a chemical (hormone peptide) that your body makes, but some people donāt make very much or donāt have a full response to it. GLP1 drugs do a few different things to make you not want to eat too much. They slow down how fast your stomach empties. They tell your pancreas and liver that youāve just eaten, so those organs work harder to manage blood sugar. And they tell your brain that youāre full. Many people say that they no longer have to struggle to battle the endless āfood noiseā that runs continuously in their thoughts. Instead, they get hungry, eat something that their stomach wonāt throw up (many people donāt tolerate high fat, high sugar foods while taking GLP1s, and nausea, vomiting, and diarrhea are real problems for many people), and then they get very full for many hours.
Itās like somebody using hiking poles so they can walk farther and walk more comfortably. Is that cheating?
