How Cronometer changed my nutrition practice (and can change yours too!)

I’m Susan Macfarlane and I’m a Registered Dietitian Nutritionist running a busy private practice in Canada’s capital of Ottawa, Ontario. I’m also a nutrition contributor at Cronometer, where I answer all your nutrition and health-related questions in the forums.

In my practice, I am an expert consultant on vegan and vegetarian diets, and specialize in weight management and eating disorder recovery. As such, I spend much of my day conducting food recalls and analyzing dietary records. Although this provides me with valuable information about my clients’ dietary patterns and nutrient intakes, the process is quite tedious and time-consuming. And despite feeling knowledgeable and competent in my role, it is difficult to determine the dietary adequacy for all essential forty-ish nutrients from memory. Consequently, I often feel as though I only have a snapshot of my clients’ true dietary intake.


One-of-a-kind nutrition software

I have dabbled with various nutrition apps in the past, but am usually underwhelmed by the nutrients analyzed and the databases used. On the advice of a friend, I decided to test out Cronometer for a few days using my own diet and was impressed with the results. Not only did Cronometer accurately predict my calorie and protein requirements, it also looked at essential amino acids, fatty acids, vitamins, and minerals, alerting me to those that were low in my diet. As a result of this feedback, I started adding almonds to bump up my vitamin E intake, and a tablespoon of hemp seeds to bring my ratio of omega 3 to 6 into the desirable range.


How Cronometer can enhance your nutrition practice

Given the benefit I derived from Cronometer, I decided to use the nutrition software in my practice and quickly realized that not only was it saving me time and energy, it was also empowering my clients to make more informed food decisions. Below is a summary of how I am using Cronometer as a dietitian and the ways in which it has added value to my practice.


Visual comparison of energy intake relative to energy expenditure

Cronometer uses the Mifflin St. Jeor equation, with relevant activity factors, to predict estimated energy requirements. In addition, there is the option to track daily and weekly calorie expenditure from structured activity through Cronometer’s exercise database derived from the 2011 Compendium of Physical Activities.

A visual depiction of energy intake relative to expenditure can be found beneath the food diary, providing a quick, at-a-glance reference of energy balance.

Comprehensive vitamin and mineral assessment

When my clients come to me, they want to know if they are missing any vitamins or minerals from their diet, and if so, how they can add them in. Using Cronometer, I can determine if my clients are at risk of a nutrient deficiency/excess by comparing their intake of essential nutrients to the Dietary Reference Intakes (DRIs). Hovering your mouse over a nutrient allows you to take your analysis one step further and see where the nutrient is coming from in your clients’ diets.

Provides features for special populations

All nutrient targets in Cronometer can be individualized, which is incredibly beneficial when working with clients with unique nutritional requirements. One of my favourite features is the ability to track “Net Carbs” or total carbohydrates minus fibre. This feature has simplified carb counting for my clients with diabetes, helping them to better understand how food influences their blood sugars.

Cronometer also offers the option of tracking as a pregnant or breastfeeding female, with nutrient targets reflecting the increased needs of this population.


Monitoring of biometric values

Cronometer allows for the monitoring and evaluation of important anthropometric and biochemical measures that inform you, as the clinician, if your nutrition intervention is achieving its intended goal. Gold members also have the option of tracking additional biometric values that are relevant to their area of practice.



The Professional account takes your practice to the next level

Cronometer recently released their “Pro Account”, which has been a game-changer in my practice. As a pro member, I can view my clients’ diaries prior to their appointment, generate detailed nutrition reports, and share recipes and foods that I have created in my own diary. Additionally, I have the option of creating accounts that only I can see, which I use for my clients with eating disorders to track their weight progress, biochemical values, and dietary intake.

Your pro account also gives you access to the professional database where you can advertise your services, skills, and areas of expertise to prospective clientele.

Cronometer empowers your clients

By far the greatest benefit I have seen since using Cronometer in my practice is the change in my clients’ eating habits. Knowledge truly is power and my clients report that Cronometer has been an asset in helping them lose weight and improve the quality of their diets.

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.
