B-OK turns thirty years of clinical practice into a 44-lesson journey you actually finish — your own eating plan, your own activity plan, and a way to track what's really changing.
Free to start. No account required to begin your first lesson.
Your day, your journey, your progress — one screen, always where you left it.
Meals, activity, and lessons laid out on a single 24-hour clock — always know what's next.
The book, walked one video at a time. Quiz after each one — never a gate, always a check-in.
The Action Center gathers anything you've missed, sorted by what matters most, one tap to catch up.
You choose the ratio. You choose the intensity. B-OK never picks for you — it makes sure you're choosing with real information.
A carb-to-protein ratio that fits how you're approaching things right now — 2:1 or 1:1, your call.
Switch Training at your level — A, B, or C — with a week that flexes as you progress.
How you feel, how you look, how you live — tracked together, not just a number on a scale.
