Looking for a Whitney Simmons calorie calculator?

If you follow Whitney Simmons and want to plan your nutrition alongside strength training, start with maintenance calories: total daily energy expenditure (TDEE). Eating around maintenance aims to keep weight stable; eating below or above it aims for weight loss or gain. Your first target is an estimate, not a measurement of exactly what your body burns.

For her associated workout app, see the official listing for Alive by Whitney Simmons. A training program and a daily calorie target serve different purposes. This is an independent guide, not an official Whitney Simmons calculator; MacroCodex is not affiliated with or endorsed by Whitney Simmons or Alive and does not reproduce their programs or nutrition methods.

Calculate a daily calorie target for free

  1. Open MacroCodex and enter your details to get an initial maintenance-calorie estimate.
  2. Choose maintenance, weight loss, or weight gain. The app turns your maintenance estimate into a daily calorie target for that goal.
  3. Record your calorie intake and body weight consistently. MacroCodex updates its maintenance estimate and targets as it learns from your trend.

MacroCodex free app continuously tracks maintenance calories using State Space Neural Network.

You do not need to pursue weight loss just because you start lifting. Choose your food target for your own goal, and consider strength, recovery, and how you feel alongside scale weight. If your goal is muscle gain, a lower number on the scale is not automatically a better outcome.

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. Judge progress across weeks rather than adjusting your target after one weigh-in.
