High-Impact Clinical Research
Active Focus vs. Background Intelligence
Nutrition science demonstrates that tracking 20+ variables simultaneously causes decision fatigue and logging burnout. BunnyCal's dual-architecture separates daily behavioral focus from comprehensive metabolic scanning.
Default Core View (8 Nutrients)
Kept front-and-center on your home dashboard to prevent logging burnout: Fiber, Sugar, Sodium, Potassium, Calcium, Iron, Vitamin C, and Vitamin D. These 8 biomarkers provide 90% of actionable daily feedback for energy, cardiovascular health, and bone density.
Background AI Vision (20 Nutrients)
Whenever you snap a meal photo, BunnyCal's neural vision models calculate all 3 macronutrients and all 20 micronutrients silently in the background. You gain full clinical diagnostic depth without ever needing to manually search 20 different nutritional values.
Customizable Dashboard
Promote any background nutrient to your active view or silence irrelevant metrics. Endurance athletes promote sodium & hydration; plant-based eaters surface B12, zinc & iron; heart-conscious users track saturated fat & cholesterol ceilings.
What You See vs. What BunnyCal Calculates
Clean daily dashboards for peace of mind ā accompanied by institutional-grade background telemetry.
Active Front-Facing View (Default 8)
Minimal Cognitive Overhead* Selected to provide maximum actionable impact on digestion, hydration, bone conservation, and glycemic stability without overwhelming daily routines.

AI Vision EngineMacronutrient Targets & Metabolic Science
BunnyCal eliminates guesswork by pairing gold-standard resting metabolic equations with large-scale clinical meta-analyses on resistance training and cardiovascular health.
Energy (BMR & TDEE)
Men: BMR = (10 Ć wt in kg) + (6.25 Ć ht in cm) - (5 Ć age) + 5 Women: BMR = (10 Ć wt in kg) + (6.25 Ć ht in cm) - (5 Ć age) - 161
- Proven 5% within indirect calorimetry limits in 82% of non-obese and 70% of obese individuals.
- Superior accuracy over older Harris-Benedict (1919) formulations.
- Activity multipliers prevent metabolic adaptation and excessive lean mass loss.
Dietary Protein
Scaled dynamically based on lean body mass, training frequency, and whether the user is in a hypocaloric deficit or hypertrophy surplus.
- Intakes beyond 1.62 g/kg show diminishing returns for fat-free mass accretion in eucaloric states.
- Intakes up to 2.2 g/kg provide critical muscle preservation during aggressive hypocaloric fat-loss deficits.
- Distributed evenly in 0.40 g/kg meal boluses to maximize muscle protein synthesis (MPS).
Dietary Fats & Lipids
Floor calculated at 0.7g/kg minimum to protect testosterone synthesis, steroidogenesis, and fat-soluble vitamin absorption (A, D, E, K).
- AMDR baseline of 20%ā35% prevents essential fatty acid deficiencies.
- Saturated fat is clinically constrained to <8% of total daily energy to optimize LDL cholesterol clearance.
- Focus is placed on monounsaturated (MUFA) and polyunsaturated (PUFA) marine omega-3 sources.
Dietary Carbohydrates
Carbohydrate Kcal = Total Caloric Target - (Protein Grams Ć 4) - (Fat Grams Ć 9); Carbs (g) = Carbohydrate Kcal Ć· 4.
- Tailored to glycogen replenishment based on workout volume and training intensity.
- Prioritizes unrefined, high-fiber complex carbohydrates with low glycemic variability.
- Flexibly accommodates low-carb or ketogenic goals (<50ā80g) when chosen by the user.

View Full Peer-Reviewed Academic CitationsDynamic Metabolic Adaptation Factors
Static RDAs assume an average 70kg male eating a standard omnivorous diet. BunnyCal dynamically scales biological requirements to reflect your bio-individuality, sex dimorphism, dietary matrix, and energy flux.
Age & Sex Dimorphism
Hormonal and Skeletal Calibrations
BunnyCal automatically scales micronutrient targets to match physiological realities, such as bone-density conservation in post-menopausal women and sex-specific iron losses.
Premenopausal women require 18mg iron vs. 8mg for adult men to offset menstrual losses. Women 51+ receive a +20% calcium increase (1,200mg) and magnesium scaling per IOM guidelines.
Plant-Based Bioavailability
Phytate & Non-Heme Adjustment Engine
Plant foods contain dietary phytates and oxalates that bind divalent minerals. BunnyCal automatically adjusts iron and zinc requirements when a vegan or vegetarian preference is selected.
Applies an evidence-based 1.8Ć multiplier to iron (increasing target to 24mg/14mg) and +50% to zinc (16.5mg/12mg), while elevating cobalamin (B12) to 4.0 mcg to bypass intrinsic factor saturability.
Calorie & Expenditure Scaling
Metabolic Throughput Proportionality
Static micronutrient targets fail high-energy athletes. BunnyCal scales hydration, fiber, and electrolytes proportionally with your daily caloric throughput and workout volume.
Fluid targets adjust using the validated Armstrong 1.15 ml per consumed kcal equation, plus sweat replacement offsets. Fiber scales dynamically at 14g per 1,000 kcal to maintain optimal GI motility.
Custom Overrides & Autonomy
Doctor & Dietitian Protocol Alignment
Every body is unique. BunnyCal provides full clinical sovereignty: you or your healthcare provider can override any target, set custom ceiling limits, or silence specific nutrients.
Whether managing chronic kidney disease (requiring potassium/sodium limits), hyperferritinemia (iron ceilings), or medical ketogenic therapy, BunnyCal puts precise boundary control in your hands.
