Study Shows How Orexin Makes You Snack Instead of Sweat

The Struggle is Real: Why We Reach for the Wrong Foods

There are countless excuses as to why many of us reach for the wrong foods instead of prioritizing our fitness goals. The pressures of work, lack of downtime, and feelings of stress or anxiety often play havoc with our motivation levels. But how do some people manage to prioritize their fitness despite these challenges? Science may have finally found the answer, and it’s not just about willpower.

The Science Behind Orexin

A recent study published in Nature Neuroscience observed that levels of the brain chemical orexin may directly determine whether we indulge in unhealthy snacks or engage in physical activity. The study provided mice with a milkshake bar and a running wheel, and manipulated their orexin systems to see how this affected their behavior.

The Importance of Exercise

The World Health Organisation reports that more than 80% of adolescents and 27% of adults are failing to complete enough exercise. This is a significant concern, as regular physical activity is essential for our overall health and well-being. Finding out how to overcome these challenges is crucial for the survival of our species.

What is Orexin?

Orexin, also known as hypocretin, is a neuropeptide that regulates various bodily functions, including arousal, wakefulness, and appetite. While other chemicals like dopamine can influence our choices, dopamine doesn’t explain why we might choose snacks over exercise, as it is released by both activities.

The Study’s Findings

The study found that mice with blocked orexin systems spent twice as much time running and half as much time at the milkshake bar compared to those with intact orexin levels. In other words, reducing orexin levels in mice made them choose exercise over snacks when both options were available.

According to Denis Burdakov, Professor of Neuroscience at ETH Zurich, the results suggest that the primary role of the orexin system is not to control physical activity or food intake, but rather to make the decision between the two when both options are available.

Implications for Humans

For humans, the option to choose physical activity or snacks is usually available with a little planning. The good news is that scientists believe that restoring adequate orexin levels could help us make healthier choices. However, a miracle pill may not be needed. Experts also know that glucose is an orexin inhibitor, so reducing sugar intake can make it easier to choose workouts over eating out.

Conclusion

The study’s findings have significant implications for our understanding of the complex relationship between orexin and our choices. By recognizing the role of orexin in our decision-making process, we can take steps to optimize our brain chemistry and make healthier choices. Whether it’s reducing sugar intake or finding other ways to boost orexin levels, the key to success lies in understanding the science behind our behavior.
