tdlr: This is a Novo Nordisk-funded study focusing on predictive biomarkers rather than real-world dementia cases. Novo Nordisk's actual dedicated clinical trials for Alzheimer's completely failed to show that semaglutide stops cognitive decline.
"A predictive biomarker is like a "check engine" light on your dashboard. It warns you that there is a risk of a future problem. In this study, the researchers only checked if the drug turned off the "check engine" light (by measuring blood proteins), rather than testing if the car was actually driving properly (by testing the patients' actual memory and brain function)."
Always do FIRST analysis on studies. Or have AI do it for you. I used Gemini to dig into this:
"Novo Nordisk funded this study, and several of the researchers are employees or minor shareholders. While corporate funding doesn't automatically mean the data is fabricated, it does mean the company is highly motivated to find and publish data that makes their blockbuster drug (semaglutide, marketed as Wegovy, Ozempic, and Rybelsus) look like a preventative treatment for a wider range of conditions, expanding its market and driving up profits."
"Funding: The study was funded by Novo Nordisk A/S.
Investigation: Researchers conducted a post hoc analysis using data from the randomized, placebo-controlled SELECT trial. They applied the Dementia SomaSignal Test (dSST)—a 25-protein risk score—to non-fasted serum samples collected at baseline and at week 104 to estimate 5-year and 20-year all-cause dementia risk in patients receiving semaglutide (2.4 mg) versus a placebo.
Results: Semaglutide significantly attenuated the progression of the dementia risk signature. Compared to the placebo group, the 5-year predicted risk increased 2.5-fold less (a 26.0% lower predicted event rate) and the 20-year risk increased 1.67-fold less (an 8.8% lower rate). Semaglutide also lowered the odds of patients moving into a higher dementia risk category by 36%.
Subjects: The analysis included 2,970 older adults aged 65 and older (mean age of ~69.7 years) who had overweight or obesity and cardiovascular disease, but no history of diabetes. The cohort consisted of 814 women (27.4%) and 2,156 men (72.6%).
Time: The study evaluated data over a 104-week (2-year) follow-up period. The analysis was published on August 8, 2026."
And then map the weakness to each respective letter if you want to dig deeper.

Not only that but high intakes of added sugars and fast-acting, high-glycemic carbohydrates are linked to an increased risk of cognitive decline and dementia. Excess simple sugars, particularly fructose and sucrose, promote insulin resistance, chronic inflammation, and vascular damage that impair brain function and accelerate neurodegeneration. So with other words, you diet is a major contributing factor here. The medical establishment and big pharma simple ignores the fact that the biggest health risk for a human being is the "modern" high sugar diet that Kellogs introduced in the US and spread to the western world (even to Asia at some extent).

I'm not sure how the medical establishment ignores this, from my understanding (and please correct me if I'm wrong as I'm not fact checking myself in this moment) - the association between the two is largely linked to vascular dementia (obesity, hypertension, yadda yadda).
I think it's hard to argue "The medical establishment" ignores diet as an important factor.
I think the reality a lot of the time is doctors prescribe something to help. They can't force a diet change on a patient, and they're not mutually exclusive interventions.

> The medical establishment and big pharma simple ignores the fact that the biggest health risk for a human being is the "modern" high sugar diet
The medical establishment isn’t ignoring this at all. They’ve been pushing for healthier diets forever. Primary doctors have always been pushing for healthy eating.
That doesn’t mean patients welcome the advice or follow it. Everyone knows that eating high sugar diets and being overweight is unhealthy.
There was some short-live resistance to the idea that being overweight was unhealthy, but that wasn’t coming from the medical establishment. That was an anti-science, anti-medicine movement that went mainstream under a misplaced desire to not make anyone feel bad in any way. That movement has lost steam quickly as an easier option has appeared for reducing appetite and inducing weight loss.
I don’t understand how you’re trying to twist this into a claim that big pharma is ignoring the impact of unhealthy eating. GLP-1 drugs work by reducing unhealthy overeating and cravings for unhealthy foods.

Fructose is blood sugar invisible, and plays no part in this conversation. Fructose can cause fatty liver and has been attributed with lots of voodoo, but the weird fructose focus of some is not evidence based. It's nonsense.
"The medical establishment and big pharma simple ignores the fact "
Do you really think the "medical establishment" hasn't been *screaming* about poor diets for decades? The fact that people ignored them doesn't give you an opening to suddenly spout horseshit. And big pharma has had an enormous focus on blood sugar for decades, and you're here yipping like they just want to sell you boner pills. What bizarre world is this?
> the "modern" high sugar diet that Kellogs introduced in the US and spread to the western world (even to Asia at some extent).
Kellogg? Did you know that white rice has a glycemic index significantly higher than table sugar (because, as previously mentioned, fructose is not a blood sugar)?
Yeah, a lot of people have bad diets, but infinitely more pressing is sedentary lifestyles. The reason Asia gets away with a rice-heavy diet (which is almost pure glucose, in a very simple form), though this is turning the wrong way, was busy, active lifestyles. The biological reality is that eating a big bowl of frosted flakes is perfectly fine if you follow it up with high amounts of activity.
Glucose is quite literally fuel for your body. And it's fine if you're actually using that fuel, but becomes a problem when often the overweight (and insulin resistant) and sedentary flood their blood with glucose, with nowhere for it to go.

> Fructose can cause fatty liver
It is also a large contributor to rising triglycerides levels and uric acid due to the way it is metabolized. Which in turn contributes to high blood pressure. It also makes Acetyl-CoA, which stimulates lipogenesis.
It is not even true that it is 'blood sugar invisible'. 30-50% of the fructose is converted in glucose and that's visible. The rest won't be available until you start burning fat.
> Yeah, a lot of people have bad diets, but infinitely more pressing is sedentary lifestyles.
No, that's only part of it. And a small part at that. The world didn't suddenly decide to get less active all of a sudden. You can blame some of the sedentary behaviors on societal changes (like suburbs and car dependency in the US), but other countries are getting just as unhealthy, metabolically speaking, and fat.
> The biological reality is that eating a big bowl of frosted flakes is perfectly fine if you follow it up with high amounts of activity.
It has to be really high. We are talking about hours to burn up that bowl of frosted flakes. Spend an hour at a treadmill, calculate the calories you spent. Now check the nearest cereal bar nutritional information. You'll be in for a surprise. You cannot outrun a bad diet.
Diet is most of what needs to be controlled for metabolic health. Resistance training will build muscles, and they are a good buffer since they will eat simple carbs even when you are inactive. Add cardio for cardiovascular health. But, unless you are an athlete or you are active the whole day, you should go easy on the frosted flakes.

I have some individual anecdotal evidence. I spent a long time, basically a year, relatively heavy but on a very small dose of GLP drugs due to tolerability issues, and my labs improved dramatically, to a degree we redid them out of disbelief, even without weight loss. I believe one of the suspected underlying causes is reduction in fatty liver despite constant body weight and composition, and also inflammation reduction directly through GLP influence in other areas of the body.
I'm not great evidence because N=1 and all the confounders, but I found that it absolutely made me much healthier without weight loss. I then went on to increase the dose slowly and have lost a bunch of weight and my labs improved even more, which I attribute mostly to the body mass reduction.

Similar experience here on minimal dose of GLP-1. There is definitely something going on here other than "you are just losing weight and that's really why you are healthier".

All my immediate family members are obese. I'm not (BMI 24.5, borderline overweight at the high end of normal, highest lifetime BMI was 29.5), but that's through strenuous, exhausting effort over decades. I also exercise regularly, though I've learned over time how disconnected exercise is from weight management.
At my weight, I'm not a candidate for going on a GLP-1. I'm sure I could find an unethical doctor to prescribe it if I looked hard enough, but I don't want to have the downsides hidden from me.
My weight has been steadily ratcheting up over the years, since I don't have as much room in my life as I used to for living with the discomfort of caloric deficit. If that continues, I will probably become a candidate for GLP-1s, like my immediate family members, just after a decade or so of possibly unneeded striving.
Lots of people are in situations far worse than mine, so I don't feel unlucky — but it would be nice if there were a clearer path forward. While lowering risk for Alzheimer's is not a priority for me, other effects of GLP-1s sound extremely enticing — especially reports of reduced food craving.
jaggederest 5 minutes ago [-]
Speaking as someone who had the same kind of reservations, I think you sound exactly like me, and if I had any advice to my past self, it would be "get on it as early as it's available, start much lower than anyone thinks is sane, and never ever stop".
I got a concierge doctor who absolutely evaluates what I ask for skeptically, and pay for my GLP medications out of pocket, so I feel ethically totally comfortable with this position. The downsides are real and significant, it's not a "fun" medication, but just the change in how I feel is worth every penny, let alone the massive reduction in heart attack risk, liver enzyme numbers, and so on.

Semaglutide was invented in the early 2000s. Weight loss is an extremely complicated and societally mediated problem that we didn't have a 'cheat code' like this for until recently.
Aurornis 1 hours ago [-]
That is the question now. Some studies have some early evidence that GLP-1s might reduce inflammation markers a little more than weight loss alone.
Giving GLP-1s to normal weight people doesn’t work well because they can have to work harder to maintain their weight. That can be a real problem as people get older where maintaining muscle mass is important for quality of life and longevity. I remember how hard it was to keep some of my grandparents at a healthy weight, so adding a GLP-1 to a non-obese elderly group is a no-go for study purposes. Going to be hard to separate these effects out.

Seriously though, it's a dogshit thing to consume whether it is sweetened with HFCS or sucrose.
"Even today, a Soda with 'real sugar', at least for me, is far more satiating"
Did you know that in the acidic environment of a cola, sucrose quickly degrades into fructose and glucose (and if it didn't, your enzymes literally immediately crack sucrose into them). You know, exactly the same fructose and glucose that would be added by HFCS. The proportions differ a tiny amount, but this notion that one is satiating and the other isn't should really send you down a path of self-discovery, where you determine how you fell for nonsense.

I think you need to read up on why the civil rights act was necessary and the things it fought for. Woman's suffrage was fought for a long time ago, but that does not mean it was universally applied.
Many many times in US history we've said something is true, but put some big asterisks after them. Slavery is over (except it's definitely still permitted in the US), it's illegal to discriminate based on race (except we allowed redlining for generations and arguably are still fighting it), rape is illegal (unless it's your spouse, then it was legal until '93. And a lesser crime still in much of the country).
Voting is no different. Heck, one might argue we still don't have universal suffrage. People who want to vote but because we've put barriers like underfunding stations, long lines, not giving time off to vote, etc. we're clearly preventing some types of people.

... It can cut both ways, and depends a lot on the 'level' of poverty and specific circumstances, although the calculus has shifted over time.
If people are working crazy hours, sometimes it's a struggle to even get time to properly shop for groceries, let alone cook. There's varying degrees of that too;
i.e. I remember the 3-4$ frozen pizzas that could be used as a dinner and leftovers; And yes, at least back then, We could instead buy some chicken, rice, and a can or two of soup or stock to do something way healthier, at the same overall cost per meal...
But it would take an hour or so to properly prepare instead of just tossing that 3-4$ frozen pizza into the oven and letting it do it's thing.
Then throw into the mix where both partners due to work and/or school aren't even home till 8PM, and one of them has to wake up by 7AM to get to work the next morning [0]
I've lived that situation, although thankfully that wasn't every night and we could balance between the healthy self cooked option and the junkish-food-pizza.
But I've also lived the situation where both parties are working late, or the commute is so bad, you're glad you advanced enough you could afford the more expensive, but at least then managable 'taco bell' option.
But then there's the sort of 'generational passing on' where we now have multiple generations raised on carry out, fast food, or microwaved meals. Sometimes where they were never given the teaching or responsibility of cooking because (for reasons similar to above, including more affluent cases) the general concept of 'a home cooked meal' becomes the exception case rather than the norm [1]

I lost 40 pounds in a year(230 to 190) at age 50. Great! I also went from being active and fat(weightlifting with some cardio) to basically having no energy. In the last year I've had arthritis appear in several joints. I'm awake several times a night to pee(yeah, prostate is acting up but I still void completely. The semaglutide is like a diuretic for me at night.). I get waves of hypoglycemia like feelings where I feel weak and spaced out. I'm afraid to get off of it because now my joints can't handle the extra weight.

Western disease and sugar heavy diets broadly speaking, which Semaglutide is a countermeasure against. Not yet a vaccine, but in due time (probably via gene therapy). Fructose also helps cancer metastases and spread.
First of all it’s a nice study. The dosages they always give are way too high and mice are rarely a reliable model.
But you’re also ignoring the fact that the same study shows that glucose inhibits the behavior.
So your claim that the study indicates its sugar is incorrect. The study indicates a possible impact from fructose which is countered by glucose, so the real issue is the fructose to glucose ratio.
Table sugar providing equal fructose and glucose molecules is acquitted by this study.

At the risk of being argumentative I had a horrible diet for the past ~10 years and carried 50 extra pounds. However I also exercised a lot as a hobby and to my shock my glucose and other bloods always came out in the normal range.
This year I started Mounjaro and dropped the 50 pounds. Curious to see what my next checkup shows.

People kick around the idea of the "personal fat threshold". E.g. caucasians seem to be better at carrying fat than, say, Southeast Asians. White people seem to be able to better store fat without metabolic side effects; SEA seems to get T2D at a much lower bodyfat percentage.

Just pattern matching as an autistic human. Similar results were seen on a ketogenic diet (and to some extent, intermittent fasting). What do they have in common? Sugar intake reduction. Is it surprising sugar potentially fuels cancer, contributes to dementia, etc? It shouldn’t be. It’s indirect and a casual connection.
There is no health benefit to a high sugar or Western diet, only downside. I think calling it poison is hyperbole, but it’s definitely not healthy, based on all available evidence. I expect to see longitudinal scale results over the next decade as everyone starts taking GLP-1s.

Although it's encouraging, they do mention that the reduction in the BMI also have an effect (they take it into the consideration by lowering the β −0.092 to β −0.066 (P < 0.001)).
Just skimming through it, it's possible there are direct benefits, but it could also be other environmental factor. This study will most likely generate others that give us more insight in the future.

Read a interesting piece recently that Semaglutide reduces inflammation, and very likely the weight-loss and a lot of the other emerging benefits are likely the effects of reduced inflammation.

> and very likely the weight-loss and a lot of the other emerging benefits are likely the effects of reduced inflammation.
That’s not correct. GLP-1s interact with satiety (fullness) circuits and reduce appetite. They also have minor effects delaying gastric emptying, meaning the stomach stays full longer.
There is some early data suggesting that they might reduce some inflammation markers slightly more than weigh loss alone, but losing weight and controlling food intake without GLP-1s reduces the same inflammatory markers. The question now is if GLP-1s have additional anti-inflammatory influence.
I don’t know why someone would claim all of their effects are downstream of inflammation. Some people get stuck in modes where they think inflammation is the cause of everything and can’t comprehend causal effects going in the other direction.

For sure we still need to find out many related outcomes.
Last year it become known that it increases (high relative risk, low absolute risk) non-arteritic anterior ischemic optic neuropathy (NAION), ie sudden, sometimes permanent vision loss.
To save others the click: It increased the likelihood to 1 in 10,000 in adults with type 2 diabetes.
Diabetics are already more prone NAION. This studies contribution was to show that diabetics on GLP-1's are MORE prone. It does not show that the general population is more prone when taking GLP-1's.
I didn't check to see if other studies prove that.

It is well known that forcing a sudden drop in chronically high average blood glucose (like, from 200+ to a normal ish range) with insulin can cause vision loss. I wonder if it's the same mechanism?
adam_arthur 2 hours ago [-]
It tends to happen when:
1) You must have a crowded optical disc as a precursor (low cup to disc ratio). Genetic and can be tested
2) You have stiff veins/arteries due to poor metabolic/cardio health
3) when blood pressure drops too much, blood flow can get cut off to the optical nerve temporarily due to reliance on high blood pressure due to 2
4) Due to loss of blood flow, optic nerve swells and closes blood flow into the eye due to 1
adam_arthur 2 hours ago [-]
It's also true that having a crowded optical disc is pretty much a required precursor condition to suffering NAION.
Which you can get checked for via a $50 optical scan.
No crowded disc, very little risk.
(Cup to Disc ratio of 0.2ish or less starts to present risk)

In addition to being closely associated with the conditions semaglutide treats, NAION is quite rare.

If it reduces inflammation and causes weight loss, I find it impossible to believe you can just stop and not get rebound on both.
Which to me just sounds like every other addictive drug. Paradise while you’re high, and eventually you pay for it.
"A predictive biomarker is like a "check engine" light on your dashboard. It warns you that there is a risk of a future problem. In this study, the researchers only checked if the drug turned off the "check engine" light (by measuring blood proteins), rather than testing if the car was actually driving properly (by testing the patients' actual memory and brain function)."
Always do FIRST analysis on studies. Or have AI do it for you. I used Gemini to dig into this:
"Novo Nordisk funded this study, and several of the researchers are employees or minor shareholders. While corporate funding doesn't automatically mean the data is fabricated, it does mean the company is highly motivated to find and publish data that makes their blockbuster drug (semaglutide, marketed as Wegovy, Ozempic, and Rybelsus) look like a preventative treatment for a wider range of conditions, expanding its market and driving up profits."
"Funding: The study was funded by Novo Nordisk A/S.
Investigation: Researchers conducted a post hoc analysis using data from the randomized, placebo-controlled SELECT trial. They applied the Dementia SomaSignal Test (dSST)—a 25-protein risk score—to non-fasted serum samples collected at baseline and at week 104 to estimate 5-year and 20-year all-cause dementia risk in patients receiving semaglutide (2.4 mg) versus a placebo.
Results: Semaglutide significantly attenuated the progression of the dementia risk signature. Compared to the placebo group, the 5-year predicted risk increased 2.5-fold less (a 26.0% lower predicted event rate) and the 20-year risk increased 1.67-fold less (an 8.8% lower rate). Semaglutide also lowered the odds of patients moving into a higher dementia risk category by 36%.
Subjects: The analysis included 2,970 older adults aged 65 and older (mean age of ~69.7 years) who had overweight or obesity and cardiovascular disease, but no history of diabetes. The cohort consisted of 814 women (27.4%) and 2,156 men (72.6%).
Time: The study evaluated data over a 104-week (2-year) follow-up period. The analysis was published on August 8, 2026."
And then map the weakness to each respective letter if you want to dig deeper.
I think it's hard to argue "The medical establishment" ignores diet as an important factor.
I think the reality a lot of the time is doctors prescribe something to help. They can't force a diet change on a patient, and they're not mutually exclusive interventions.
The medical establishment isn’t ignoring this at all. They’ve been pushing for healthier diets forever. Primary doctors have always been pushing for healthy eating.
That doesn’t mean patients welcome the advice or follow it. Everyone knows that eating high sugar diets and being overweight is unhealthy.
There was some short-live resistance to the idea that being overweight was unhealthy, but that wasn’t coming from the medical establishment. That was an anti-science, anti-medicine movement that went mainstream under a misplaced desire to not make anyone feel bad in any way. That movement has lost steam quickly as an easier option has appeared for reducing appetite and inducing weight loss.
I don’t understand how you’re trying to twist this into a claim that big pharma is ignoring the impact of unhealthy eating. GLP-1 drugs work by reducing unhealthy overeating and cravings for unhealthy foods.
"The medical establishment and big pharma simple ignores the fact "
Do you really think the "medical establishment" hasn't been *screaming* about poor diets for decades? The fact that people ignored them doesn't give you an opening to suddenly spout horseshit. And big pharma has had an enormous focus on blood sugar for decades, and you're here yipping like they just want to sell you boner pills. What bizarre world is this?
> the "modern" high sugar diet that Kellogs introduced in the US and spread to the western world (even to Asia at some extent).
Kellogg? Did you know that white rice has a glycemic index significantly higher than table sugar (because, as previously mentioned, fructose is not a blood sugar)?
Yeah, a lot of people have bad diets, but infinitely more pressing is sedentary lifestyles. The reason Asia gets away with a rice-heavy diet (which is almost pure glucose, in a very simple form), though this is turning the wrong way, was busy, active lifestyles. The biological reality is that eating a big bowl of frosted flakes is perfectly fine if you follow it up with high amounts of activity.
Glucose is quite literally fuel for your body. And it's fine if you're actually using that fuel, but becomes a problem when often the overweight (and insulin resistant) and sedentary flood their blood with glucose, with nowhere for it to go.
It is also a large contributor to rising triglycerides levels and uric acid due to the way it is metabolized. Which in turn contributes to high blood pressure. It also makes Acetyl-CoA, which stimulates lipogenesis.
It is not even true that it is 'blood sugar invisible'. 30-50% of the fructose is converted in glucose and that's visible. The rest won't be available until you start burning fat.
> Yeah, a lot of people have bad diets, but infinitely more pressing is sedentary lifestyles.
No, that's only part of it. And a small part at that. The world didn't suddenly decide to get less active all of a sudden. You can blame some of the sedentary behaviors on societal changes (like suburbs and car dependency in the US), but other countries are getting just as unhealthy, metabolically speaking, and fat.
> The biological reality is that eating a big bowl of frosted flakes is perfectly fine if you follow it up with high amounts of activity.
It has to be really high. We are talking about hours to burn up that bowl of frosted flakes. Spend an hour at a treadmill, calculate the calories you spent. Now check the nearest cereal bar nutritional information. You'll be in for a surprise. You cannot outrun a bad diet.
Diet is most of what needs to be controlled for metabolic health. Resistance training will build muscles, and they are a good buffer since they will eat simple carbs even when you are inactive. Add cardio for cardiovascular health. But, unless you are an athlete or you are active the whole day, you should go easy on the frosted flakes.
Proving correlation but not causation does NOT rule out causation.
If this is caused by the weight loss, it is a little disappointing that public health didn't act quicker - lots of people have been overweight for a century now, so literally 10's of millions of people could have been saved from dementia had action been taken 100 years ago.
I'm not great evidence because N=1 and all the confounders, but I found that it absolutely made me much healthier without weight loss. I then went on to increase the dose slowly and have lost a bunch of weight and my labs improved even more, which I attribute mostly to the body mass reduction.
With my labs at my current weight you can not tell that I am a type 2 diabetic. Previously, when I was at this very same weight in the past - all my labs indicated I was prediabetic.
At my weight, I'm not a candidate for going on a GLP-1. I'm sure I could find an unethical doctor to prescribe it if I looked hard enough, but I don't want to have the downsides hidden from me.
My weight has been steadily ratcheting up over the years, since I don't have as much room in my life as I used to for living with the discomfort of caloric deficit. If that continues, I will probably become a candidate for GLP-1s, like my immediate family members, just after a decade or so of possibly unneeded striving.
Lots of people are in situations far worse than mine, so I don't feel unlucky — but it would be nice if there were a clearer path forward. While lowering risk for Alzheimer's is not a priority for me, other effects of GLP-1s sound extremely enticing — especially reports of reduced food craving.
I got a concierge doctor who absolutely evaluates what I ask for skeptically, and pay for my GLP medications out of pocket, so I feel ethically totally comfortable with this position. The downsides are real and significant, it's not a "fun" medication, but just the change in how I feel is worth every penny, let alone the massive reduction in heart attack risk, liver enzyme numbers, and so on.
Edit: although, there are well-known links between overweight and a lot of negative outcomes, and yet people are still too fat.
Giving GLP-1s to normal weight people doesn’t work well because they can have to work harder to maintain their weight. That can be a real problem as people get older where maintaining muscle mass is important for quality of life and longevity. I remember how hard it was to keep some of my grandparents at a healthy weight, so adding a GLP-1 to a non-obese elderly group is a no-go for study purposes. Going to be hard to separate these effects out.
What does treat them like cigarettes mean? Tax them? Ban them within 15 feet of a building entrance? Put warning labels? Is giving or selling French fries to children a crime? Does this apply to food made at home?
Even today, a Soda with 'real sugar', at least for me, is far more satiating for thirst or a 'quick sweet treat' than the same brand/'flavor' using corn syrup, that includes both the big chains as well as the local names.
If I drink a soda with sugar in it, I usually wind up wanting water after. If I drink something with corn syrup, I usually just want more of whatever I just had.
Seriously though, it's a dogshit thing to consume whether it is sweetened with HFCS or sucrose.
"Even today, a Soda with 'real sugar', at least for me, is far more satiating"
Did you know that in the acidic environment of a cola, sucrose quickly degrades into fructose and glucose (and if it didn't, your enzymes literally immediately crack sucrose into them). You know, exactly the same fructose and glucose that would be added by HFCS. The proportions differ a tiny amount, but this notion that one is satiating and the other isn't should really send you down a path of self-discovery, where you determine how you fell for nonsense.
I think the former makes much more sense than the latter, since it is literally being funded by the govt. That's a reasonable first step, or possibly only step, especially considering that most people on food stamps are also on govt-funded/subsidized healthcare (meaning taxpayers will end up footing the bill when they require expensive treatments resulting in part from an unhealthy diet).
Proper sleep, eating less (including liquid calories), and exercising have been the mainstream medical advice for many decades.
Obviously, most people can’t accomplish that for whatever reason, so another solution was needed.
did western society engineer a junkfood-industrial-complex so addicting and so en-sickening that it ultimately required a sort of junk food methadone to wean itself off?
Lobbies and general government ineptitude have been a problem longer than obesity and that one needs to be solved first.
I imagine people hundred years in the future will think of our current society rightfully as dumbfucks. But should we be surprised? 50 years ago women didn't have voting rights; homosexuals were incarcerated in western societes; all because of moral and power implications of some powerful men. Not much different with Semaglutide.
Where are you? In the US, women have had full voting rights for over 100 years.
Many many times in US history we've said something is true, but put some big asterisks after them. Slavery is over (except it's definitely still permitted in the US), it's illegal to discriminate based on race (except we allowed redlining for generations and arguably are still fighting it), rape is illegal (unless it's your spouse, then it was legal until '93. And a lesser crime still in much of the country).
Voting is no different. Heck, one might argue we still don't have universal suffrage. People who want to vote but because we've put barriers like underfunding stations, long lines, not giving time off to vote, etc. we're clearly preventing some types of people.
When did all the voter suppression become illegal? 1965.
When I grew up relatively poor we never ate out or ate junk food because it is ridiculously expensive in comparison. We made our food from cheap ingredients. To save money.
Yes it takes more time and is far more work and is less convenient. US society has valued convenience over everything else for a few generations now. Cheaper it is not.
And it holds true today with my own grocery shopping. Cooking meals and being smart about grocery shopping is far cheaper per meal than buying premade junk. The few times I do have a cart full of products from the middle aisles I am astounded at how expensive it is.
If people are working crazy hours, sometimes it's a struggle to even get time to properly shop for groceries, let alone cook. There's varying degrees of that too;
i.e. I remember the 3-4$ frozen pizzas that could be used as a dinner and leftovers; And yes, at least back then, We could instead buy some chicken, rice, and a can or two of soup or stock to do something way healthier, at the same overall cost per meal...
But it would take an hour or so to properly prepare instead of just tossing that 3-4$ frozen pizza into the oven and letting it do it's thing.
Then throw into the mix where both partners due to work and/or school aren't even home till 8PM, and one of them has to wake up by 7AM to get to work the next morning [0]
I've lived that situation, although thankfully that wasn't every night and we could balance between the healthy self cooked option and the junkish-food-pizza.
But I've also lived the situation where both parties are working late, or the commute is so bad, you're glad you advanced enough you could afford the more expensive, but at least then managable 'taco bell' option.
But then there's the sort of 'generational passing on' where we now have multiple generations raised on carry out, fast food, or microwaved meals. Sometimes where they were never given the teaching or responsibility of cooking because (for reasons similar to above, including more affluent cases) the general concept of 'a home cooked meal' becomes the exception case rather than the norm [1]
[0] - You don't want to eat too late for other health reasons of course...
[1] - And yes, that group really does tend to be less healthy overall from my personal experiences, even if their dining tastes are 'expensive'.
Price out a bag of rice, a bag of beans, etc.

I lost 40 pounds in a year(230 to 190) at age 50. Great! I also went from being active and fat(weightlifting with some cardio) to basically having no energy. In the last year I've had arthritis appear in several joints. I'm awake several times a night to pee(yeah, prostate is acting up but I still void completely. The semaglutide is like a diuretic for me at night.). I get waves of hypoglycemia like feelings where I feel weak and spaced out. I'm afraid to get off of it because now my joints can't handle the extra weight. My doc recommended going to every other week now that my BMI is normal but as far as I can tell that advice isn't backed up by any research. Anyway, it's a powerful drug that works well but is not without side effects.
Also, do you cut pills? I had looked into this and only found info saying that it ruins the delivery mechanism. I was skeptical of this because it would benefit the pill makers to convince people that these special pills cannot be cut, even though they do not require extended delivery (quite the opposite).
Eating less can have positive effects (losing weight), but can also make you feel like shit (in a wide variety of ways), as your body is running on less energy intake than it has been accustomed to.
Depending on your activity level and the makeup of your diet, eating less can also lead to muscle loss and nutrient deficiencies.
This extra receptor is why Reta is a triple agonist unlike semaglutide (single glp1) or tirzepatide (glp1+gip double agonist).
It's something we found and started using to one specific problem, but it later turned out that it has lots of other, extremely wide-ranging consequences. Except that in this case, these consequences are positive.
Unpicking the exact chains of causation is likely going to be extremely complex, but the general picture continues to look good.
But if GLP-1 makes you more active, who am I to complain. There's the reason they approve stomach stapling surgeries on morbidly obese people. They are so compromised that anything that gives them a chance to be more active offsets some of the risks of surgery, and the risks of inaction.
