Body Intelligence
Know Your Body, Not Just Your Weight
Clinical-grade body composition scanning paired with nutrition correlation intelligence. See exactly how what you eat shapes how your body changes — lean mass, body fat, visceral fat, and segmental balance, all connected to your daily nutrition.
Composition
Body Composition Analysis
Your scanner captures the raw data. NutriJourney turns it into a living profile — tracking every compartment of your body over time so you can see what is actually changing, and why.
- Segmental lean mass tracking across arms, legs, and trunk — spot imbalances before they become injuries *
- Body fat percentage trends with rolling averages that cut through day-to-day noise
- Visceral fat level monitoring — the metric that matters most for long-term metabolic health *
- Left-right muscle imbalance detection so you can correct asymmetries early *
Cause & Effect
Nutrition and Body Correlation
This is where numbers become strategy. JUNA correlates your nutrition intake with your body composition changes over weeks and months — showing you the cause behind every result.
- Your protein increase over the last 4 weeks mapped directly to lean mass gains — proof your plan is working
- Higher fiber intake correlated with visceral fat reduction — JUNA shows you the trend before you feel it
- Macro ratio changes connected to body fat shifts — see which adjustments actually moved the needle
- JUNA synthesizes scan data + nutrition logs into personalized insights that no result sheet can provide
Energy Intelligence
Energy Impact Analysis
Understand how every meal affects your energy, focus, and performance. NutriJourney scores your meals by their energy response impact and helps you optimize timing for sustained performance.
- Glycemic Impact Score for every meal — know which foods deliver steady energy versus a crash
- Thermic effect analysis: see which meals cost more energy to digest, amplifying your deficit without eating less
- Meal timing optimization based on your training schedule and energy response patterns
- Energy stability scoring across your day — JUNA identifies the meals that fuel you and the ones that stall you
Cycle Intelligence
Cycle-Aware Nutrition
Your metabolism, cravings, and recovery shift across your cycle — but most apps ignore it entirely. JUNA detects your phase from wearable skin temperature and eating pattern changes, then adjusts your nutrition targets automatically.
- Phase detection from Polar skin temperature trends and eating pattern shifts — no manual logging required *
- Iron, magnesium, and B6 targets auto-adjust per phase to match your body's changing demands
- Water retention noise filtered from your real body composition trends — see actual fat and muscle changes, not cycle fluctuations *
- Calorie targets shift with your metabolic rate — the luteal phase burns more energy, and JUNA accounts for it *
Luteal Phase
Day 18 of 28 — detected from Polar
Adjusted Targets
JUNA Insight
Your weight is up 1.2 lbs this week — this is water retention typical of your luteal phase, not fat gain. Your actual body comp trend is still declining.
Cycle Overview
Your Body, Fully Understood
Understand what's changing, why it's changing, and what to do next.
Weight Trend Intelligence
Noise-filtered weight tracking that separates real body composition changes from daily fluctuations caused by water retention, sodium intake, and meal timing.
Segmental Analysis
Left versus right, upper versus lower — detailed segmental breakdowns reveal muscle imbalances and guide targeted training and nutrition adjustments.
Daily Metabolism Adjustment
Your targets aren't static. JUNA recalculates daily based on what you actually ate, your training load, sleep quality, and metabolic adaptation — so tomorrow's plan always reflects today's reality.
*Certain features deliver the highest precision when paired with compatible hardware (InBody scanner, Polar wearable, or similar devices).
Without hardware, JUNA estimates these metrics using your nutrition logs, weight trends, and self-reported data — still useful, but less precise. Hardware integrations are optional and enhance accuracy over time.
