What it does

Research from global health institutions like the World Health Organization highlights rising sugar consumption and increasing rates of Type 2 diabetes among younger populations.

However, most nutrition apps:

Count calories

Track weight

Ignore metabolic modeling

CarbHEALTH shifts the focus from calories to metabolic impact.

How we built it

CarbHEALTH is an interactive youth-focused metabolic intelligence platform that:

Tracks carbonated drinks and traditional carbohydrates

Classifies carbs by glycemic impact

Simulates energy spikes and crashes

Projects long-term metabolic strain

Gamifies learning with trivia and Carb IQ scoring

⚙️ How We Built It

The system is structured around a predictive metabolic modeling engine.

1️⃣ Sugar & Carb Load Calculation

For each logged food or drink, we compute total carbohydrate exposure:

Carb Load

Carbs (g) × Frequency Carb Load=Carbs (g)×Frequency

For sugar-sweetened beverages:

Annual Sugar Load

Weekly Sugar × 52 Annual Sugar Load=Weekly Sugar×52

This allows us to quantify cumulative exposure over time.

2️⃣ Insulin Strain Index (ISI)

We designed a simplified metabolic stress estimator:

ISI

( Sugar Intake × Absorption Factor ) ( Activity Level Modifier × Body Weight Modifier ) ISI= (Activity Level Modifier×Body Weight Modifier) (Sugar Intake×Absorption Factor) ​

This models how liquid sugar (which absorbs faster than solid carbs) places strain on insulin response.

3️⃣ Five-Year Risk Projection

We implemented a weighted risk model based on epidemiological dose-response logic:

Projected Risk

𝑅 0 + 𝛼 ( Carb Exposure ) + 𝛽 ( BMI ) + 𝛾 ( Age ) − 𝛿 ( Activity ) Projected Risk=R 0 ​

+α(Carb Exposure)+β(BMI)+γ(Age)−δ(Activity)

Where:

𝑅 0 R 0 ​

= baseline metabolic risk

𝛼 , 𝛽 , 𝛾 , 𝛿 α,β,γ,δ = weighting coefficients

This produces a relative metabolic risk projection, not a diagnosis.

4️⃣ Engagement & Gamification

To ensure youth engagement, we added:

“Did You Know?” carb trivia

Carb IQ Score

Streak system

Sugar accumulation counter (e.g., “You will consume 18kg of sugar in 1 year at this rate.”)

This transforms learning into interaction.

Challenges we ran into

Accomplishments that we're proud of

What we learned

While building CarbHEALTH, we learned:

Liquid sugar causes faster glucose spikes than solid carbohydrates.

Many “healthy” foods contain significant carbohydrate loads.

Fiber dramatically changes glycemic response.

Small daily habits create large cumulative metabolic effects.

We also learned that data visualization can make invisible health risks tangible.

When users see a 5-year projection curve rising, the impact becomes real.

What's next for CarbHEALTH

CarbHEALTH is more than a tracker.

It is a platform that:

Translates public health research into youth-friendly intelligence

Encourages preventive metabolic awareness

Bridges fitness, education, and predictive analytics

Turns everyday carb choices into measurable future impact

Our goal is simple:

Help young people understand that small daily carb decisions shape long-term metabolic outcomes.
