Platform Features
Every module is physician-designed, evidence-graded, and calibrated to your biometrics — not population averages.
US Navy body fat formula (±3%), weekly progress photo tracking with Claude AI vision analysis, adaptive calorie and cardio recommendations based on your weekly weight trend.
Personalized meal plans for omnivore, vegetarian, vegan, ketogenic, and low-carb preferences. Protein targets calculated at 1.8 g/kg lean mass. Food-drug interaction screening for current medications.
Evidence-graded tiers (Core, Performance, Longevity) with third-party certification verification (NSF, USP, IFOS, Creapure). Real-time drug interaction screening against current medications.
Periodized strength programs for beginner, intermediate, and advanced levels. Zone 2, HIIT, and VO₂ max interval protocols. Cardio prescriptions calibrated to your Garmin VO₂ max and heart rate data.
Lab results tracker for HbA1c, lipid panel, inflammatory markers, hormones, and vitamins. HRV monitoring, sleep stage analysis, and evidence-reviewed longevity protocols (NMN, rapamycin, senolytics).
Garmin Health API integration syncs steps, resting HR, HRV, active calories, sleep score, and VO₂ max in real time — feeding every recommendation engine across all five pillars.
Garmin Health API
Generic wellness apps guess at your needs. Leanthletic uses your Garmin data to know them — updating every recommendation in real time as your body responds.

Resting HR & HRV
Recovery & autonomic nervous system status
VO₂ Max
Strongest single predictor of all-cause mortality
Sleep Score & Stages
Deep sleep, REM, light — and total duration
Active Calories
Exercise energy expenditure
Stress Score
Derived from HRV variability throughout the day

About Leanthletic
Leanthletic was built because most wellness apps optimize for engagement — not outcomes. They use population averages instead of your actual data, recommend supplements without checking your medications, and provide generic calorie targets that ignore your real activity.
Every feature in Leanthletic is derived from peer-reviewed literature and clinical practice. The nutrition targets are validated at 1.8 g/kg lean mass by meta-analyses. The body fat formula is the same used by the US military. The cardio protocols follow the Seiler polarized training model endorsed by leading sports scientists.
When Garmin wearable data is integrated, Leanthletic stops estimating and starts knowing — adjusting every recommendation in real time based on how your body actually responded.
"The goal is not more data — it is the right data, interpreted correctly, and acted upon immediately."
— Founding Physician, Board-Certified Internal Medicine
All protocols, targets, and recommendations reviewed by a practicing Internal Medicine physician. Safety checks built into every module.
Each recommendation links to the clinical literature that supports it — from TDEE formulas to supplement certification standards to longevity biomarker targets.
No health data is sold. Wearable data is stored encrypted and used only to power your personal recommendations. Users can delete all data at any time.
Monthly evidence brief reviews the latest clinical research. Recommendations update as the science evolves — not locked to a static algorithm.
Privacy & Data
We collect the minimum data necessary and handle it with the same standard of care we apply to clinical recommendations.
When users opt in to AI body composition analysis, photos are sent to the Anthropic Claude API for analysis. Photos are processed in real time and are not retained by Anthropic beyond the API request. API keys are stored in session memory only and cleared when the browser tab closes. Users are informed before any photo is transmitted.
Garmin data is accessed only with explicit user authorization via the OAuth 2.0 flow. Data is encrypted at rest and in transit using AES-256 and TLS 1.3. Only the specific data points necessary for recommendations are requested. Users can disconnect their Garmin account at any time, which immediately revokes access and removes stored data.
