Our purpose

Carb Cycling is a free planning tool for people who want to organize carbohydrate, protein, fat, and meal targets around their own routine. It turns a chosen plan into a practical day-by-day schedule, with optional AI assistance for meal ideas and adjustments.

What the tool provides

  • Macro and carb-cycle target calculations.
  • Meal planning, food logging, and progress tracking.
  • Public meal-plan inspiration and community discussion.
  • Optional AI tools that require your review before any plan is changed.

Our approach

We aim to make planning transparent: you can see targets, food quantities, and the changes proposed for a plan. Core planning features do not require AI.

Important health information

Carb Cycling provides educational and organizational tools, not medical, nutritional, or mental-health treatment. Individual energy needs and dietary restrictions vary. Consult a qualified healthcare professional before changing your diet if you have a health condition, take medication, are pregnant, or have a history of disordered eating.
