From the first BMI calculation to daily coaching to provider routing — here's exactly how Sisu fits into your week.
You enter height, weight, age, sex. Sisu calculates BMI, BMR, TDEE, and an estimated body fat percentage in seconds. No signup needed for this step — the calculation runs in your browser.
A quick 8-condition checklist — diabetes, hypertension, sleep apnea, PCOS, and others. This step is what separates a one-time calculator from a coach: your conditions shape what Sisu will and won't suggest.
Clear, honest guidance based on what licensed providers typically consider — BMI thresholds and weight-related conditions: are you likely to meet the standard criteria, borderline, or is medication probably not the right path right now? The guidance explains the reasoning — no upsell, no false positives. A licensed provider makes the final determination.
If you create a free account, this is where Sisu introduces itself. A 90-second profile setup covers your goal, sleep, activity, lifestyle, and (optional) deeper data like blood group for future blood-insights features.
Sisu generates a plan: diet style (with cuisine preferences for Pro users — Indian, Mediterranean, East Asian, etc.), exercise rotation, daily habit anchors, and a realistic weekly trajectory. The plan adapts every Sunday based on what you logged the previous week.
One number, one tap. Sisu reacts to the delta and the trend — not a canned "great job" toast. Your streak builds, your data accumulates, your coaching improves as the model has more signal to work with.
If GLP-1, hair loss treatment, longevity peptides, or another prescription path is part of the right answer, Sisu routes you to a US-licensed partner clinic matched to your state and profile. You decide whether to engage. Inline affiliate disclosure on every routing screen.
Sisu notices patterns across categories — your sleep dropped before your weight stalled, your stress is spiking on weeks your hair routine slips. Coaching across categories is where Sisu earns its keep. No other wellness app integrates this way.
