Looking for a Kayla Itsines calorie calculator?
If you follow Kayla Itsines and want a daily calorie target alongside your workouts, start with maintenance calories, also called total daily energy expenditure (TDEE). Eat around that amount for maintenance, below it for weight loss, or above it for weight gain. The first estimate is a starting point to check against your actual intake and weight trend over the following weeks.
Kayla Itsines' official website identifies her as Sweat's co-founder and head trainer and links to her programs in the Sweat app. Visit it for her own workout resources. This is an independent guide, not an official Kayla Itsines calculator; MacroCodex is not affiliated with or endorsed by Kayla Itsines or Sweat and does not reproduce their programs or nutrition methods.
Our claim: See measurable weight gain or weight loss results within 2–3 weeks of using MacroCodex. Many users start seeing results as early as the first week.

Calculate a daily calorie target for free
- Open MacroCodex and enter your details to get an initial maintenance-calorie estimate.
- Choose maintenance, weight loss, or weight gain. The app turns your maintenance estimate into a daily calorie target for that goal.
- Record your calorie intake and body weight consistently. MacroCodex updates its maintenance estimate and targets as it learns from your trend.
Workout frequency is only part of your activity level. A few weekly sessions do not describe the rest of your day: a desk job, walking, and physical work also affect your energy needs. Avoid assuming the same food target fits everyone following a particular program. Use your longer-term trend to assess your starting estimate.
MacroCodex is free and has no ads or subscription. It asks you to enter daily calorie totals; if you want a food diary, you can use a separate logger such as CalorieCodex. This general adult guide is not a pregnancy or breastfeeding calorie plan; seek individualized advice from your clinician or a registered dietitian in those situations.
