Sugar Alcohols, Vitamin D study, and Supplements

Sugar Alcohols

We’ve now added support to track total Sugar Alcohols (polyols) in the carbohydrate breakdown. Please note we only currently have data for this in some of our whole foods database. By default they are not tracked as a target in your diary, but you can enable this on the Profile tab.

GrassrootsHealth Vitamin D Study

You can now join and link to an ongoing long-term study on Vitamin D.  Through them you can order your at-home vitamin D blood test kit and have your vitamin D serum levels measured every 6 months. Linking your cronometer account with their system will allow sharing your diary data with the researchers. They hope to learn more about how your diet, exercise, and supplementation affects your vitamin D serum levels. If you want to enroll, visit the Profile tab in cronometer and enroll in the Sharing section.

Supplements Store

Need dietary supplements like protein powders, workout & recovery supplements, and vitamins? We’ve partnered with to bring our US customers a supplement store with a great selection of high quality supplements.  Get some great deals and help support cronometer at the same time by ordering through our supplement store.

Retiring unused Foods & Recipes

If you’re like me, you have a lot of older custom foods and recipes you no longer use. We’ve added an item to the food editor’s menu to ‘Retire’ a custom food. Instead of entirely deleting the food (and all the associated servings that used it), a retired food is not deleted from the system, but will no longer appear in your food lists and searches.

Your historical data using the retired food or recipe will remain unaffected.

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.

ketomodeKetogenic Mode

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

keto settingsIn 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.

What’s Up With Vitamin A?


What’s up with vitamin A and Cron-O-Meter? I have one lousy small carrot and I am at 278% of my daily requirement for vitamin A. Is that correct? And to add to it all, vitamin A is supposedly toxic at high doses. First, it is correct, and in this blog I will address what is going on and shed some light on what is up with vitamin A.

Carrots, spinach, kale, bell peppers, sweet potatoes, cantaloupe, apricots, broccoli, tomatoes, and asparagus are all excellent sources of vitamin A. Vitamin A will preserve and improve your eyesight and help you fight off viral infections. It is known as the “anti-viral vitamin”. It is also a fat-soluble vitamin and needs fat to dissolve it and transport it within the body. Deficiencies may be caused by a diet that is extremely low in fat.

There are two different types of vitamin A. The first type, preformed vitamin A (retinol), is found in meat, poultry, fish, and dairy products. The second type, provitamin A (carotenoids), is found in fruits, vegetables, and other plant-based products. The most common type of provitamin A in foods and dietary supplements is beta-carotene.   Preformed vitamin A and provitamin A is where the confusion comes in.

Toxicity can occur with excessive intakes of preformed vitamin A (retinol) and not necessarily with provitamin A (carotenoid) intake. The dosage levels that need to be obtained to cause toxicity are difficult to attain through food alone. Toxicity usually has been associated with prolonged supplement intake over a long period of time.

Symptoms of getting too much preformed vitamin A (retinol) can cause dizziness, nausea, headaches, coma, and even death according to the National Institute of Health (NIH).

Consuming high amounts of provitamin A can turn the skin yellow-orange in color, but this condition is harmless.

In Cron-O-Meter (CM) you can click on “vitamin A” and open a box that displays the daily recommended intakes (DRI), which are CM’s default settings. The range in the picture is for a fifty-year-old male.  These are also editable and you can put any range you desire into them.

Vitamin A

The DRI’s and tolerable upper limits (UL) for preformed vitamin A can be found on the site   There are no limits established for provitamin A (carotenoids, beta-carotene).

We get a lot of questions when one carrot reflects 278% of your daily value, but we here at Cron-O-Meter can’t tell you what amount to take or what ranges to use. That decision is left to you and your healthcare team. We hope this blog will help you understand why CM states what it does and what it means allowing you to be better informed and make the decision that is best for your health.

Live well!

Net carbs and total carbs are an option now.

On the diary page below where you put your foods eaten for the day, you will find the calorie summary box. By clicking on the gear icon on the top right of the box, you will get an expanded version of the calorie summary section. At the bottom right you will see the dynamic macronutrient targets area depicted below.

At the very bottom of this section, you will see the option to select ‘Total Carbs” or “Net Carbs”.  This selection will be the carbohydrate percentage format that is depicted on the blue carbohydrate macronutrient bar.

Dynamic Macronutrient Targets: What They Mean

In this blog we will discuss the new change to Cron-O-Meter, dynamic macronutrient targets and what the targets in the dropdown menu (zone, paleo, ketogenic, LFRV) mean and resources for you to learn more on their specifics.

On the diary page below where you put your foods eaten for the day, you will find the calorie summary box. By clicking on the gear icon on the top right of the box, you will get an expanded version of the calorie summary section. At the bottom right you will see the dynamic macronutrient targets area depicted below.

This area will allow you to select different macronutrient (protein:carb:fat) ratios to follow. The drop down menu has some popular built in ratios that you can select.   Here are what they are and what they designed to do according to the leaders in those areas:

  1. Default: This setting will set your targets to the RDA standards based on your age. Click here for the current RDA table.
  1. Even: This is an even ratio of 1:1:1 (protein:carb:fat) or 33.3% each.
  1. The Zone: The ratios in The Zone are 3:4:3 (30%/40%/30%). The primary ingredients are low-fat protein, colorful carbohydrates rich in polyphenols, and fat that is low in both saturated fat and omega-6 fats.
  1. Paleo: Paleo is the rage now and it is a ratio of 15:20:65. A Paleo dietshould be high in fat, moderate in animal protein and low to moderate in carbohydrates. Loren Cordain is one of the leading experts on the Paleo Diet. It does have some restrictions like no dairy, grains, legumes, refined sugars, and salt.
  1. LFRV: Is a high carb, low fat vegan approach with a 1:8:3 (8%/67%/25%). More can be found here:
  1. Low carb/Keto: This diet is a 5:1:5 (45.5%/9%/45.5%) ratio. The ketogenic diet was designed in 1924 by Dr. Russell Wilder at the Mayo Clinic. It has many claims, but also has some cautions. You can learn more at:
  1. Custom: Selecting custom will allow you to put whatever ratio combination you desire in the boxes. With this selection the boxes will become active to be edited.

These options we give you need to be considered carefully and with your health practitioners.

At the very bottom of this section, you will see the option to select ‘Total Carbs” or “Net Carbs”.  This selection will be the carbohydrate percentage format that is depicted on the blue carbohydrate macronutrient bar.

Once you have set a target to follow, you can select the top box “show full macronutrient breakdown” and four sets of bars will now be depicted in the calorie summary. Here is what will be added to your view:

Screen shot Calorie summary net:total carbs targets

The top bar is a depiction of your custom energy target for the day (Basal Metabolic Rate, BMR) based on the vitals you set up on the profile page.   You can customize your target calories by clicking this bar. The protein, carbs, and fat targets below will now automatically be adjusted based on BMR and the ratios you have selected in the targets area.

We hope this will help you use Cron-O-Meter more effectively to obtain your desired health goals. The selections in the macronutrient target area are informative and you must be careful on which ratio you desire to use. We strongly urge you to consult a health practitioner to help you choose the target range that best suits your needs and goals.

Please let us know if this post was helpful and if you have any questions. In our next blog I will discuss the “net” and “total” carbs bar in the calorie summary box.

Live well!
