Are you also thinking of taking the help of new medicines to lose weight without putting in much effort? If yes, then wait a moment. A recent study found that new oral medications used to treat obesity don’t just suppress your appetite; In fact, they may even change a specific part of your brain that is responsible for generating feelings of happiness, inspiration, or pleasure.
Journey from diabetes medicine to weight loss
These drugs – known as ‘GLP-1 receptor agonists’ – were originally designed for type 2 diabetes patients to help their bodies use insulin more effectively. Initially, weight loss was considered an ‘additional benefit’ of this treatment. Scientists previously believed that these drugs affected only lower parts of the brain, causing feelings of fullness or nausea; But, researchers from Virginia University of America have made an important new discovery through experiments conducted on rats.
New drugs that reach deep into the brain
Research shows that recently approved oral medications – such as denuglipron and orforglipron – reach deep into the brain. These medicines create direct connections between the lower part of the brain (brain stem) and the ‘central amygdala’ (the center of the brain that works to understand emotions). Additionally, they also affect the neurons that are responsible for producing ‘dopamine’ (a hormone associated with happiness). This complex neural circuit determines exactly how much pleasure we get from high-calorie, tasty food or any other pleasurable thing.
These medicines not only eliminate hunger but also eliminate cravings for tasty food.
The lead researcher of this study and neuroscientist, Ali D. Guler, explains this entire process in very simple words. He says, “What we’re showing is that these drugs don’t just suppress appetite; they actually eliminate your urge to eat a delicious piece of cake. They work on the system that triggers cravings – the system that makes you want to eat the cake – rather than just the system that signals hunger.” The study, published in the renowned scientific journal *Nature*, also sheds light on why some weight loss drugs make some people feel extremely nauseous, while newer drugs in this class act directly on the brain without causing any physical discomfort – and simply eliminate the desire to eat.
Will the fun of life end? In the current situation, pharmaceutical companies are giving more importance to making oral tablets rather than injectable drugs, because tablets are easier and cheaper to make, and they do not spoil for a long time. This makes it easier for millions of people around the world to access these medicines. However, the researchers also issued an important warning. If these drugs are indeed affecting the brain’s “reward system,” their effects may not be limited to just weight loss. This can have a profound impact on human behavior:
Potential benefits: Early evidence suggests that these drugs may help some people overcome addictions, such as cigarette smoking, or binge eating habits. This can prove to be a major breakthrough in the field of drug addiction treatment.
Potential Risks: On the other hand, some people may feel that all the joy or fun has been taken away from their lives. This can affect a person’s sense of self-control and their ability to feel happy.
Gular is confident that these medicines are very effective. As people begin to incorporate these into their everyday lives, it will be important to keep a close eye on them so we can fully understand how they are affecting both our bodies and our minds.
