The most common questions about how KEXBI works, what it needs, and who it’s for.
MacroFactor is an adaptive TDEE tool. It adjusts your daily calorie target based on weight trends. KEXBI already calculates adaptive TDEE. That is one function inside a much larger decision engine.
KEXBI does not stop at a daily number. Fuel, hydration, and recovery are timed to your biology. Sleep, strain, HRV, and environment are processed continuously. If your data changes, the plan can rebuild in around 3 minutes.
MacroFactor gives you a number. KEXBI orchestrates your entire day.
For a detailed comparison of KEXBI vs MyFitnessPal, Cronometer, and MacroFactor, see What Actually Changes Your Plan?
Yes, within biological limits.
KEXBI prevents aggressive deficits that damage metabolism or strip lean mass. If you want a crash diet, this is not it.
No, but it weakens the system.
KEXBI is strongest when it can read sleep, HRV, strain, and recovery signals. Without that data, it falls back to more static maths, which removes much of the advantage.
An iPhone 16+, a kitchen scale, and consistency.
A wearable is strongly recommended. Already logging food? Keep your current app. KEXBI reads from Apple Health.
Missing a day does not break anything.
The system falls back to your physiological data. When you return, it recalibrates.
No. Every meal is built around your targets, calories, macros, and timing.
Eat something different, log it, and the system accounts for it in your remaining day. If you build a consistent logging habit, the engine unlocks intra-day replanning, adjusting the rest of your meals around what you actually ate.
Energy and gut stability: 4 to 6 days.
Body composition: 3 to 4 weeks.
Biomarkers: 8 to 12 weeks.
Consistency determines speed.
Yes. Eight weeks. No card required.
The only requirement is that you use it properly. If you disappear for 7 days without warning, your seat goes to someone on the waitlist.
KEXBI relies on on-device processing and Apple Health integration.
Android follows once the core system is stable.
The TestFlight build expires.
Cohort 001 users who complete the protocol receive lifetime founder pricing.
We read the health and activity data needed to run your plan, including sleep, HRV, and energy expenditure through Apple Health.
Your data is never sold. It is never used to train public AI models. It exists only to run your system.
