Tracking Issues with Cron-o-meter and my Macros.

I'm starting off on Keto and want to ensure i'm tracking things properly so I know how i'm doing. I have chosen Cron-o-meter for it's great ability to display status, tracking of net carbs.

I am 37, 258 (fitbit scale says 37% BF) , 5'10 and I have a reasonably office lifestyle.

Once calculator says 1850 kcal Daily Calorie Intake 25 g Carbs (5%, 100 kcal) 120 g Protein (26%, 480 kcal) 141 g Fat (69%, 1270 kcal)

Another says 2086 calories 163 g fats 25 g carbs 129 g protein

Cron-o-Meter wants to calculate my protein based on lean weight, so it wants only 97G, but it wants my fats at 434.3g.

What's right? Also how can I get chronometer to display correctly because the calculation in it seems to be messed up no matter what.

    Hi Williamgomes,

    Cronometer has a couple of options that you can choose from to set your Macronutrients targets for your diet plan.

    1. In the Profile tab, select Macronutrient Targets, then choose High Fat/Ketogenic

    This will allow you to choose one of the preset calculations for your macros.
    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).
    Net carbs will be limited to the value in grams shown. 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.

    1. 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.
