Carb Cycling Calculator

Carb cycling itself does not cause fat loss - total weekly calories still determine fat loss. What it does is structure intake to fuel hard workouts and reduce calories on rest days, which can make maintaining a deficit more manageable. The practical benefit is that having planned high-carb days prevents the "all-or-nothing" thinking that often derails consistent low-calorie eating.

In this calculator, protein stays constant across all day types. The typical recommendation for carb cycling (aimed at muscle preservation during fat loss) is 1-1.2 g per pound of body weight (2.2-2.6 g/kg). Higher protein also increases satiety and has a higher thermic effect than carbohydrates or fat, supporting both weight management and lean mass retention.

Yes, by classifying each training day by intensity rather than by whether you trained at all. A heavy lower-body strength session might be a high-carb day; a 30-minute steady-state cardio session might be a low-carb day; an active recovery yoga session might be a no-carb day. Match the fuel to the demand.

No. A ketogenic diet restricts carbs severely every day (typically below 20-50 g) to maintain ketosis. Carb cycling intentionally includes high-carb days that exit ketosis. Some people attempt "cyclical ketogenic dieting" by re-entering ketosis on no-carb days, but this is a specific and demanding variant. Most carb cycling protocols keep carbs moderate to high on high-carb days and simply reduced on low and no-carb days.
