The Uncomfortable Truth About Ozempic

In the last few years, Ozempic or Monjaro managed to make millions of people lose massive amounts of weight with seemingly only mild side effects. More than one in eight US adults have tried the drugs, and for the first time in history, the country's obesity rate actually fell. At the end of 2025, The Who added GLP One drugs to its essential medicines list for diabetics and released guidelines on how to use it for obesity. For the first time ever, we have a medication that reliably, quickly and seemingly safely can make people lose weight, sometimes massive amounts of weight. But as with most things related to nutrition, health, and weight loss, these medications are controversial. There are many aspects to GLP Ones, but we'll focus on one today. The potential medical revolution. These drugs could mean for obesity, one of the most deadly chronic diseases of our time that over 1 billion people suffer from and that remains largely unsolved and underfunded. It turns out GLP One drugs are the first effective medical treatment for obesity in medical history. The obesity trap In 2025, more than 1/2 of Europeans were either overweight or obese, plus one in three children. And in many countries like the US, Mexico, Chile or Saudi Arabia, the numbers are even worse today. This kills almost 4 million people each year. And if trends continue, by 2051 in three adults on earth will be obese and half of humanity will be overweight. When hearing the word obese, most people think of the extreme ends of the spectrum, but this is not correct. It's not very helpful that the definition of obese is a bit vague because bodies are pretty different. So it can be ABMI of over 30, your waist to hip ratio, or a body fat percentage of over 25% for men and over 32% for women. In the end, obese is a medical term that doesn't judge how you look. But if you have an unhealthy amount of body fat, how did we get here? For most of our history, food was scarce, so when our ancestors found a calorie bomb, binging on it was the best of ideas. The more sugar, fat and salt, the better. Our brains are wired to love these foods. They bring pleasure, enjoyment and mental release. This helped us survive in a world where food was the most important thing to worry about each day. And then the world changed overnight and suddenly our modern food environment hijacked our biology. Food is a product now and has become cheap, calorie dense and hyper palatable which means it's been engineered with addictive levels of sugar, fat and salt, making our reward centres go ballistic with joy. About half of the products in AUS grocery store are ultra processed and many are labeled in ways that are deeply misleading, like the serving sizes on packs of chips. Marketing strategies like value pricing and constant food ads stimulate us to eat more, so most people overeat regularly, sometimes without even noticing, and this is very subtle. Most people don't get overweight because they massively lack self-control. They just eat a little bit too much over a long period of time. Just a small excess, like the equivalent of half a Snickers over your maintenance calories per day, compounds to almost 5 kilograms or 10 lbs of fat after a year. This is how most people get obese, slowly, bit by bit. Since being overweight is also shamed on top of being unhealthy, we try to fix our overeating behaviour with all sorts of, well, behavioural methods. The world is filled with diets and healthy habits campaigns, but if we look at the results just telling people to eat healthier foods and to move more, there's very little In the real world. Most people gain bad most weight they lose during a diet within a year or two and often gain more afterwards, often through little fault of their own. Because once you do lose weight, your body's also working against you by trying to bring you back to the fat baseline it was used to. Really the only reliable way to do it is a lifestyle change. Not a break from calorie dense food, but a lifestyle where you eat it only occasionally or not at all, which is not just very hard but also feels like saying no to some of the best things in life. Finally, there's simply hunger. A really strong and hard to ignore signal from your body How hungry you are is genetic, so just through bad luck you may experience a lot of food noise and think about eating a lot. And to make things worse, in many people who get overweight or obese, their hunger signal becomes dysregulated. Not necessarily permanently, but even after losing weight, it can take a long time before your hunger adjusts downwards again. And this is exactly where GLP One drugs interact with our biology. Before we get there, let's fix something easier first. How we engage with the news everyday. Our partner, Ground News is a website and app built to help you think critically about the information you consume, a mission we fully support. They curate news articles from across the globe and in context on political bias, reliability, ownership, and summaries that highlight what each side is leaving out. You can even compare headlines to see how bias shapes the narrative. The same weight loss drug story might be framed as a miracle by some outlets, while others warn about harmful trends. Ground News also reveals blind spots, stories that only one side is covering, showing you what your usual news feed is hiding. As information bubbles are becoming the norm, thinking critically about the news is no longer optional, and Ground News makes it easier to do just that.

Chocolate or vegetables are actually governed by an orchestra of hormones that are not within your control. You're not hungry in the evening because you decide to be, or because this is when your body needs energy, but because your body releases certain hormones and it turns out your fat is one of the major regulators of this orchestra. If you're overweight or obese, the excess fat is throwing your hormonal orchestra out of tune. This may make you more hungry or push you to overeat more. Create creating insulin resistance that causes type 2 diabetes and so on. We made a video if you want details, but there's one specific hormone that plays its tune quietly in the background even in obese people. The Glucagon. Like peptide One or GLP One, It's one of the hormones your body releases after a meal. It tells your pancreas to release more insulin to keep blood sugar in check and slows down your digestion to keep food in your stomach and in your brain. It increases your feeling of fullness and being satisfied, curbing your appetite. These effects are usually modest. Once in your bloodstream, GLP 1 disappears in barely 2 minutes. It's song quickly fading away. So one day, scientists had an idea. What have we made? Artificial copies of GLP One that play the same song but louder and much longer. A GLP 1 signal that stays in your body would boost insulin and silence appetite. The first artificial GLP One was approved in 2005 for diabetes and in 2014 for obesity. But the revolution came with semaglutide and tirzepatite, Ozempic and Manjaro. Really powerful GLP One agonists that play their songs in your bloodstream for up to a week. They send out a loud and steady signal that dars down your appetite 24/7. You still enjoy food, but you feel full and satisfied much sooner, making it easy to not overeat. And since the song never really switches off, you feel less hungry throughout your day, making you eat less often. How intensely you feel hunger is largely genetic, so especially people who suffer from food, noise, a constant urge to eat, feel a huge psychological relief from the drug. Finally, their body stopped screaming at them. Suddenly you're dieting without expending willpower, without really thinking about it. It feels magically effortless. By changing your biology, a drug changed your behaviour. But is this a good thing? Miracle drugs? On the weight loss side, these drugs are incredibly effective. In three months you can lose 10% of your initial weight. Three months later, over 15, and after a year you may reach more than 20%, a level of weight loss that used to only ready be achievable through bariatric surgery. In other words, GLP one drugs make excess weight melt away like nothing before. We can't stress enough how unhealthy obesity is, causing everything from diabetes to heart attacks and cancer, so the consequences for health are stunning. Treatment with semaglutide cuts your risk of stroke or heart attack by 20%. The 17 months of tirzepatide crashes your chances of developing diabetes by 66%. They also reduce sleep apnea, improved kidney and liver function, lower inflammation, cut cancer risk, and may potentially slow Alzheimer's. They might even boost fertility, as obesity often disrupts hormones and increases complications during pregnancy. And there may be more positive long term effects. Some of these benefits are a direct result of weight loss, but intriguingly, they sometimes occur regardless of how much weight has been lost, and some have been seen in patients who weren't obese to begin with. We don't know why yet, but it seems like turning up the GLP 1 signal is synchronizing the whole metabolic orchestra, restoring a balance between brain, gut and body. And as if that weren't enough, GLP one drugs may also quiet other cravings. They seem to reduce the use of alcohol, nicotine, cannabis, and opioids. Large trials are underway to confirm these effects. If the results hold, they could become something unprecedented. Real anti addiction drugs, but of course there are side effects, most commonly nausea, vomiting, diarrhoea and Constipation. Not fun, but usually harmless and fleeting for the vast majority of patients. More serious stuff like pancreatitis, kidney problems or gallbladder disease do happen, but for well under 5% of people. So it's pretty risky to take these drugs without medical supervision and in extreme cases, they can land you in the emergency room. While these drugs are not really that new since diabetics have been using them for decades, because now millions of people are using them, we might discover new side effects in the coming years. Apart from this, the main downside of GLP One drugs may come from their greatest strength and rapid weight loss. If you don't actively check what you eat, taking these drugs is just an unhealthy crash diet. Any steep calorie deficit requires resistance training and plenty of protein, or else you'll lose a lot of muscle along with the fat. That's harmful at any age, but especially after 40, when building muscle gets harder and the risk of falls starts to rise. So while these drugs change your biology, they don't do all the work for you. Staying healthy still requires you to adopt healthy habits in the end. The same is true for these drugs as is for any other diet. Without a lifestyle change, you either have to use the drugs forever or you'll probably gain the weight back. After about a year, the weight loss slows down and eventually stops in most people. At this point, you usually stop using the medication. If you use that time to change your eating habits, you have a really good chance of keeping the lost weight off. But about 25% regain a significant chunk and some 20% put back on all of it. So for many, maintaining the results may mean staying on the drug forever. Is this a bad idea? Well, we don't know. The newest generation of drugs is just too new, so there's no long term data. The first GLP ones from 2005 haven't shown major issues. Based on what we know today, it seems pretty clear that living with obesity is much unhealthier than living with drugs. And to be crystal clear, this doesn't mean that these drugs are for everyone. If you want to lose a couple of pounds but are otherwise healthy and have no chronic disease, these drugs were not made for you. But you really should go the traditional route first before you start injecting drugs. Using it to get to unhealthy amounts of low body fat is definitely not a great idea. In a nutshell, the best thing these drugs do is to remove the pressure of intense hunger and food noise to give you a time window where you can change your habits. You still need to change your habits though. No drug can fix that for you. Conclusion and opinion A recent study modelled what would happen if millions of US adults who are obese or overweight got GLP one drugs for life in just two years. About 50% of all obesity in the country would vanish. Over the years. It would prevent 26,000,000 cases of diabetes, 13 million cases of heart disease and 5.5 million premature deaths, which seems like a pretty good thing. And new drugs that are in final trials promise to work even better. Defeating obesity suddenly feels within reach. Right now, the biggest obstacles are actually supply shortages and high prices, which make these drugs inaccessible for many who actually need them. Patents for semaglutide and tis appetite will expire soon in many countries, and prices for them will collapse as a result. In the long run, increased production and plummeting costs seem almost guaranteed. So should we just inject obesity away? Well, for now at least, it seems that there are few downsides. Although please don't listen to Internet videos and talk to your doctor before you make any decisions for yourself. It's also important to remember that while these drugs are immensely helpful, they are not magic. They make a hard thing easier, but it still requires you to change your habits and put in some effort. They can gain us the time we need to fix the root causes of obesity.
