Macro Tracking Changes, Ketogenic Mode, & Body Snapshots

Today we have a few changes to the dynamic macronutrients feature. These changes are on the web version only, but will be rolled out in the mobile apps as well in their next updates.

We’ve had the dynamic macronutrient targets feature for a long time, which lets you set and display preferred macronutrient ratio target. However, the macro targets have always been computed off of a fixed calorie target (the yellow bar).

Today, we are changing this to also be dynamically derived from your energy expenditure (calories burned) and your weight goal. This is more in line with what people expect, and the old behaviour has caused a lot of confusion for people.

If you stubbornly prefer it the old way, we can help you override it if you email our support.

Ketogenic Mode

Ketogenic diets are becoming extremely popular. We’ve added some specific improvements for people following a nutritional ketosis diet.

In the macronutrient settings, if you select the ‘Ketogenic’ option, now, instead of the previous fixed ratios, we dynamically calculate your maximum ketogenic protein and carbohydrate limits based on your lean body mass and exercise levels. Anything remaining, gets assigned to fats. We offer three ketogenic diet presets: Rigorous, Moderate, and Relaxed, as well as an option to choose custom values.

You can now hover your cursor over the macronutrient bars to see the top contributors to that macronutrient in your diary. This is especially helpful on a strict ketogenic diet where it can be critical to figure out what foods might be tipping you over your carbohydrate and protein limits.

In ketogenic mode, we also add some buttons next to the targets for easy logging of blood glucose and ketone measurements.

Body Snapshots

Under the trends tab we have added a new ‘Snapshots’ section where you can upload photos of your body recomposition progress. Each snapshot can store a caption and your body composition for the date of the photograph.

Please let us know what you think, and if you notice any bugs, we’ll be standing by to address them!

For more details on these features, see our User Manual.

  • Is there a way to set 'Energy' to 'cals', instead of 'kcals', when adding foods that I can't find using 'Search'?
    I'm simply trying to enter data taken directly from the nutrition labels (which so far, is almost every package) that is only listed in 'cals'...
    Or due to my brain hurting... How do I convert, if there is no setting, so I'm entering in the correct "kcals", instead of "cals"?
    Or, should we just write a letter to all manufacturers in the US, to STOP with the "cals", do it all in "kcals"!?

    • Ed,

      I hit the forum with this same response. It is misunderstanding of what the nutrition fact labels and product labels in our databases and food manufacturers mean.

      Because 1 calorie represents a very small amount of energy, the energy content of foods is typically expressed in unites of 1,000 calories, or kcalories. This is often abbreviated "kcalories" or "kcal". In addition, a kilocalorie is sometimes referred to as a Calorie (note the capital "C"), as on food labels. Therefore, 1 Calorie is equivalent to 1,000 calories or 1 kilocalorie.

      Hope that clears things up.



      • Thanks Frank... It does...
        But in my case, after I posted the question (of course!)...
        I found out why the information was being displayed improperly.
        In Firefox, I needed to update the browser...
        Went back in to attempt to 'Create New Food'...
        Now the kcals are displaying properly and not changing other values, that were not making any sense or correlation.
        Got burned on that one!
        My only problem now is how to enter supplements properly!
        For example; Multiple B-vitamins and "serving size/measurement... Only info for data-entry, is "1 tablet".

          • When doing 'Create New Food', the equivalency of each serving size, was stated clearly on the label, for example; 1 cup = 245g, etc. With all of my supplements, as stated on the label, the serving size = 1 tablet... That's it!
            So is there any calculations being done, based on the serving size entered or created, then entered as "tablet"? Or is this simply my reference only, with no translation done for how big of a "tablet"?
            Not sure I'm correctly stating what I'm trying to understand.

  • I'm not understanding the new macronutrient tracking. It says on my blank log (no entries).... "For your weight goal you can eat 445 more calories today." It makes it look like I am only allowed 445 calories, 30 g protein, 20 carbs, and 27.2 fat grams. Maybe I could warm up to this if I could understand it.

    • It sounds like you have a weight-loss goal set to a very extreme rate (-2 lbs/week?) Since that requires such a large caloric deficit to sustain, it’s set your daily calories accordingly. I suggest choosing a slower weight loss rate.

      • Okay, I changed it to lose 1 lb per week and now I'm allowed a total of 944 calories a day. This just doesn't seem right to me. I want to be able to set my own calories to 1200.

  • Firstly, I've been using cronometer for well over a year and on the whole have found it very helpful. I like the new ketogenic diet macro including the new glucose/ketone feature on the main dash.

    However I am not sure if this meets my requirements. I am on a strict ketogenic diet to combat stage 4 cancer and the goal is to attain and maintain target blood glucose as well as ketone levels without suffering excessive weight loss. Fats are the only macro I need to vary dynamically to meet calorie requirements based on changing body weight. It is also important to be able to configure target calories to enable a calorie restricted ketogenic diet when appropriate.

    1. Can you confirm that my maximum net carb target is a concrete setting I can control myself and not subject to dynamic changes (based on weight or calorie intake)?

    2. Additionally can you confirm that protein requirements always correspond to body mass and do not vary dynamically based on calorie intake? This is recommended to avoid muscle wastage.

    3. Does the remaining fat target then change dynamically to correspond to weight goals/target calories or are macro targets set up to produce a particular macro profile?

    4. There appears to be a fault with the protein target calculation. Although I weigh approx 50-51 kilos, with a protein requirement set to 1g protein per kilo of body weight, my protein target has now been set to only 40-44g - which is far too low!

    5. I was on a custom macro previously and had set individual targets across the board (including vitamin and mineral targets) based on my own research. These seem to have been reset to standard RDA levels. Can they be restored?


    • 1) You can choose the ‘Custom’ option to set exactly your net-carb and protein targets if you don’t want any of our presets. It’s a hard limit, and if you untick ‘Athletic Bonus’ it won’t add any additional carbs allowance after logging exercises.
      2) Correct
      3) Correct, fat is dynamically filling out the remainder of your calorie budget
      4) Our formula uses your _lean body mass_, not total body mass.
      5) If you choose ‘Fixed Targets’ as your option you can set your macros to exact amounts, as you see fit

      • Many thanks for your reply on the new keto feature. That all sounds good. I hadn't noticed you were using 'lean' rather than ideal total body mass but can work with that :)

        The only problem I now have is in relation to point 5 (above).

        I'm happy with the macro settings but unfortunately the personal targets I had set for individual vitamins and minerals appear to have been wiped. They have all been reset to RDA values.

        Is there some way these can be restored from your database?

        Thanks in advance :)

  • What email address am I using for support? I need my account restored to the way it was before the update. I've lost the notebook I had my macro amounts written in and this website was the only place I had them listed after I calculated them.

    Sorry for being "stubborn", but I have no need for the new service and need my macros back!

    • Reanna, you should be able to just choose the ‘Fixed Targets’ option on the dynamic macro settings and then you can click each macro bar and customize as you see fit.

  • When I tried out the new ketogenic macro setting, using the "rigorous" option, I was getting about 35g protein per day. Can that be right? I saw it was calculating .8g per KG of lbm. Every calculator I've seen and every doc I've listened to suggests about .8g to 1.5 g per LB of lbm. I'm back to using my own figures for now.

    • Everyone who advises on any diet style will have a way to implement it. We have a very credible Doctor working with us and we are using the values his research recommends. We are not saying it is best for your or anyone, that is between you and your health care team to decide. We appreciate your feedback and will look at it with our team.

      Thanks and best regards,


  • Dear admin, I put on a couple of kilos and notice my lean body mass appears to have changed resulting in different protein requirements.

    I used to be able to set my body fat but can't see that option anymore - can you please advise?

    Many thanks!

    Your site is one of the few that I have actually adblock disabled on because it’s just so good.

  • Cronometer is as powerful tool to help implement a strict ketogenic diet. Using it to track and plan meals is critical to assure compliance to the strict protein and carbohydrate targets.
    Many doctors now are advocating a metabolic approach for cancer. This tool makes the implementation of these metabolic approaches a science, even fun, especially when your life is at stake.
