Vzorec

▾
f(x)The fundamental principle of calorie cycling relies on managing your weekly energy budget. The Calkulon calculator employs the following core formulas to ensure your strategic allocation aligns with your overall objectives: `Weekly average calories = total weekly calories / 7` `Weekly energy surplus/deficit = (Baseline TDEE x 7) - total weekly intake` For instance: If your estimated Total Daily Energy Expenditure (TDEE) is 2,500 kcal, and your strategic plan incorporates five days at 2,100 kcal combined with two days at 2,500 kcal, your total weekly intake calculates to 15,500 kcal. This translates to an average daily intake of 15,500 / 7 = 2,214 kcal/day, allowing you to project your weekly energy balance with precision.
