Macros very different in Cronometer than in other App calculators?

Why are my macros in Cronometer so different from Keto Buddy (KB) Calculator or Carb Manager with the Dynamic numbers? Especially Protein. KB has me needing 88g and Cronometer at 45g. And, my fat seems low. I can’t find how to manually change this, but wonder which macro is correct (used same body information input for both). Getting message to override Cronometer with “fixed” figures, but no where can I find to change...seems videos are an older version of Cronometer. Thanks for any explanation.

    Hi Flamingo91,

    High Fat/Ketogenic targets are calculated based on the settings you have chosen in the Profile tab.

    Your protein is calculated based on your kg lean body mass (we will calculate this from your body fat %, so be sure to update your body fat biometric).
    Carbs will be limited to the value in grams shown and the rest of your energy target will go towards fat.

    If the preset strictness levels don't match the targets you would like to set, you can also choose custom and enter in your own values for protein per kg lean body mass and grams of net carbs.

    The High Fat/Ketogenic setting is a dynamic calculation, meaning that your targets can change day-to-day based on the amount of activity you have entered in your diary. If you have entered a weight loss goal, this will affect your targets as well. By reducing your calorie intake, you will also reduce the value of your fat target.
    Keep in mind, Cronometer calculates your energy target based on your basal metabolic rate (BMR), the activity level you chosen in the Profile tab. These are calculated using your age, height, weight and sex. This may account for the differences you are seeing using other calculators.

    Fixed Targets for Macronutrient Targets
    If you choose fixed targets, you will be able to define each macronutrient target in grams. This is a good option if you have calculated your macro targets elsewhere, and would like to use these instead.
    Once you have selected fixed macronutrient targets, on the mobile app, update your macronutrient targets below to the gram amounts you have chosen.
    On the website, navigate to the Nutritional Targets section to edit each macronutrient target. Click on each target, tick the box to use a custom value, enter your value and apply your changes.
