Calorie Cycling Calculator

Weekly total = average × 7. Training-day calories = average × (1 + boost). Rest-day calories = (weekly total − training-day total) ÷ rest days. The extra energy is routed through carbohydrate.

Calorie-cycling / carb-cycling energy accounting.

The weekly average drives weight change; day-to-day swings help training and adherence, not the total. Keep the average honest.

People who find variable targets harder to adhere to — a flat daily intake works just as well for body composition.

Calorie cycling means varying your intake day to day while keeping the weekly total on target. Typically you eat more on training days and less on rest days, so the average — the thing that actually drives weight change — stays where you want it.

No. Over a week, the average is what matters for weight change, and cycling doesn't change the average. Its benefits are practical: better training-day fuelling, easier adherence, and more food on the days you want it most.

Start from your maintenance or goal calories — get that from the TDEE calculator — then let this tool split the weekly total into higher and lower days. The average always equals the number you enter.

Protein stays roughly constant to protect muscle, and fat needs don't swing much day to day. Carbohydrate is the flexible fuel, so it makes sense to add it on training days when you'll use it and pull it back on rest days.

Commonly 10–20% above the average, balanced by lower rest days. Bigger swings fuel hard sessions but demand tighter discipline on rest days; start modest and adjust to what you can sustain.
