GUST-Good Food Good Mood

GUST - Good Food, Good Mood

Inspiration - Our Constant Gut Feeling

Humans often say, "trust your gut." Interestingly. modern research shows that this isn't just a saying. The gut and brain communicate continuously through the Gut-brain axis, where trillions of microbes influence mood, focus, and decision-making.

Still this communication remains invisible to us.

GUST explores how wearable technology can translate these internal signals into meaningful feedback, helping users better understand the dependency between what they eat, how they feel and how they perform.

What It Does

GUST introduces the concept of Neurobiotic Interoception - a new way of sensing internal biological states.

Using biometric data collected from Oura Ring Gen3, such as:

heart rate variability
body temperature
sleep patterns
stress indicators

GUST interprets patterns associated with gut-brain interaction.

The system then translates these signals into simple emotional and cognitive insights, helping users understand:

when their body is most focused
when decision-making take a toll
how food affects mood and productivity Instead of abstract biological data, users receive actionable awareness of their internal state.

How We Built It

Our design process involved three stages: 1. Exploring Human Senses We researched how humans perceive internal states and identified a gap in sensing the gut-brain relationship. 2. Studying Existing Technology We analyzed wearable sensors and selected the Oura Ring Gen3 as platform capable of capturing relevant physiological signals. 3. Designing Meaningful Feedback Instead of overwhelming users with raw biometric data, GUST translates signals into clear, minimal insights about mood, cognition, and timing of decisions.

Challenges We Ran Into

The biggest challenge was cognitive overload. Wearables generate huge amounts of data, but presenting too much information reduces usability.

We solved this by designing a simplified feedback system that focuses only on insights relevant to mood and decision-making.

What We Learned

Through this project we learned:

Designing for wearables requires extreme simplicity
Sensor data must be translated into meeningful human insights
Biological systems like the gut-brain axis require careful interpretation, not just raw data
