01 · Brain energy

Mental illness is, at its core, an energetic dysfunction.

Metabolic psychiatry is an emerging field exploring how metabolic health, brain energetics and psychiatric symptoms are more deeply intertwined than conventional models suggest — and whether metabolic interventions can improve mental health outcomes.

The brain accounts for roughly 20% of the body's energy use at rest. Its function depends on the same metabolic systems involved in glucose regulation, insulin signaling and energy production throughout the body.

Research increasingly points to a bidirectional relationship between metabolic and mental health: insulin resistance and metabolic syndrome are associated with higher rates of depression, bipolar disorder and schizophrenia — and people living with serious mental illness show disproportionately high rates of metabolic dysfunction in return.

Metabolica brings this emerging field into your everyday life. By tracking the signals behind your metabolism, it helps you uncover the hidden patterns that shape how you experience reality.

02 · What we track

Seven signals, one story.

Track ketones, glucose, sleep patterns and more. Metabolica turns scattered health signals into a clearer picture of the factors influencing your mental health.

Core

Blood ketones

Log ketone readings in mmol/L and track your ketosis trend over time — not just a single snapshot. Understand what moves you in and out of ketosis and identify the patterns that work for you.

Paired

Blood glucose

Log glucose alongside ketones to get a clearer picture of your metabolic state. Together, they reveal how your body is shifting between glucose and fat-based fuel over time.

Derived

GKI

A single metric that combines glucose and ketones to give you a clearer view of your metabolic state. GKI is calculated automatically with every reading.

Live

Fasting

Track your current fasting window in real time and review your fasting history to see how consistency and duration evolve over time.

The point

Mood

Log how you feel each day and connect changes in mood with your metabolic state, sleep, fasting and daily habits.

Recovery

Sleep

Track bedtime, wake time and total sleep — and uncover how your sleep patterns affect recovery, resilience and daily performance.

Habits

Addiction & habit streaks

Track the habits you want to reduce or eliminate, and build a record of every streak over time — so progress is measured by consistency, not perfection.

03 · Your metabolic story

Connect the signals. Reveal the pattern.

Metabolica tracks your metabolic signals over time, bringing each measurement into context so you can identify the trends, shifts and patterns associated with cognitive performance, emotional regulation and mental well-being.

Ketones

Track ketone levels over time to understand how deeply and consistently your body is using fat for fuel.

See the trend, not the snapshot

Individual readings can fluctuate. Tracking each signal over time helps separate daily noise from meaningful patterns.

Connect the signals

Metabolica brings your metabolic, behavioral and mental-health data into one timeline, making relationships between signals easier to see.

Understand what changes with you

By comparing patterns across time, you can begin to identify what tends to shift alongside your metabolic state, sleep, mood and habits.
