Food tracking is a valuable tool for anyone looking to improve their health. By tracking what you eat, you can get a better understanding of your dietary habits and make changes as needed. It can also provide insight into what foods work best for you and your body. 

But if you’ve never tracked your food intake before, it can be daunting and seem like a lot of work. Here are five tips to help you stay on track and make the most of food tracking.

Research Behind Food Tracking

Food tracking is an effective tool for weight loss and glucose management. In one study, participants who tracked their food intake lost twice as much weight<sup>1</sup> as those who didn’t track their food. Research also shows that individuals who track their food intake have experienced greater diet adherence<sup>2</sup> because food logging asks users to take a moment to think about their choices and creates a sense of responsibility.

There are a few reasons why food tracking can be so beneficial. It can help you become more aware of the foods you’re eating and give you a better understanding of your dietary habits. It allows you to see where changes can be made as well as recognize what foods work best for you. Recording your intake can also help keep you on track to make healthy changes. Seeing the progress you’ve made can give you the motivation to continue making healthy choices.


Food Tracking to Manage Glucose for Weight Loss

When it comes to weight loss, tracking food is especially important. Logging your food intake, as well as other lifestyle factors, can give you different insights into what can affect your health. You may find that you have to adjust your calorie intake, carbohydrate consumption, or even meal times to lose weight. 

A continuous glucose monitor that sends your glucose data to an app that includes a food log can show you how different foods affect your blood sugar in real-time. As you watch your glucose response and log the foods you eat, you’ll learn which foods, how much food, and how food eaten under certain circumstances (after exercise, for example, or when you’re sleep deprived) may impact your blood sugar levels.

How to Track Foods

Tracking your food can seem daunting at first, but it's pretty easy to learn how to do it. First,  you’ll need to track your food intake in some type of app or journal. There are several different tracking apps available, so find one that works best for you.

Then, simply enter the foods you ate and the amount you ate. Depending on the app’s features, you may also be able to track other information about how food affects your body. Things like bloating and even blood sugar responses can be assessed within specific apps. This information can help identify food triggers and trends.

The Best Food Tracking Apps in 2022

There are many different tracking apps available, and all of them have their strengths and weaknesses. Here are a few of the best food tracking apps available based on ratings and reviews in the App store:

Signos Logo


Signos members get access to a continuous glucose monitor (CGM) that sends their glucose data via bluetooth to the Signos app. Members can see their daily 24/7 glucose line graph and how what they eat, when they exercise, how they sleep, and more affect their glucose levels. 

The Signos app encourages users to track foods from a full database of ingredients and products. You’ll see the calorie content and macronutrient breakdown of all of the meals and snacks you log as well as your glucose response to the food (or combination of foods) so you can compare and contrast how different variables impact your blood sugar. This helps you make more informed decisions based on how your glucose reacts to certain foods and the app even gives you recommendations for how to stabilize your glucose if there’s a spike.

5 Helpful Tips to Stay on Top of Tracking

Food tracking can be a valuable tool for improving your health. By tracking what you eat, you can become more aware of your dietary habits and make changes as needed. It can also provide insight into what foods work best for you and your body. In the beginning, cataloging what you’re eating can be difficult. 

To help you get into the habit of food logging, Signos’ content director provides the following tips to make tracking more seamless.

1. Pre-log meals and recipes you eat often. We all have our favorite foods and go-to meals that work well to keep us sated and energized. When you aren’t running to a work meeting after a quick lunch or you aren’t helping wash the dishes and get the kids started on homework, take five or 10 minutes to pre-log meals or recipes you plan to eat this week. Or, plan your meals and snacks for the next day the night before and pre-log them when the house is quiet and before you wind down for bed. This will make it easier to track what you’re eating when you’re busy and more likely to skip logging.

2. Pre-log meals when you meal prep. Similar to the recommendation above, if you take an hour or two to prep lunches, dinners, and breakfasts, tack on an extra 10 minutes to that meal prep time to log what you made. That way you’ll remember how much arugula and roasted veggies you added to your prep-ahead mason jar salads, and you remember what you added to that chicken and veggie curry. If you take a weekend afternoon to meal prep, spend an extra 10 minutes logging the recipes you made, favorite them in the app, and then you can easily pull up what you ate during the week when you're busy (that's why you needed to meal prep, am I right?).

3. Keep an eye on the bigger picture. This means don't stress out about logging every single teaspoon of spices, fresh herbs used for garnish, or whether you used 4 Tbsp. or 2 Tbsp. of balsamic vinegar. It's awesome to be precise but if accounting for every bit of every bob you add to your homemade chili creates a roadblock to you logging the meal, strip it back to the ingredients you use in larger quantities—ground beef or turkey, beans, quinoa, chopped onions and mushrooms, canned tomatoes, etc. You’ll still likely land within 10–15 calories and around the same macronutrient breakdown for your overall meal.

4. Be reasonably accurate. The takeaway of food tracking is not to get lost in the weeds but to identify trends over time. What foods and food combinations helped you feel good and get closer to achieving your health goals? That said, accuracy matters too, when it comes to learning about portion sizes. The amount of food you eat can impact your overall health and goals. How can you be more accurate? Invest in a kitchen scale. Measuring cups and spoons work, too. How much homemade chili did you eat? How many grams of dark chocolate did you have for dessert? Approximating amounts of the main components of your meals or snacks can lead to inaccuracies that could impede your progress. If you know how much your chili bowl weighs (tip: weigh it without anything in it), then you can weigh the amount of chili you ladle into it (and subtract the weight of the bowl) and know more precisely how many portions of that homemade chili you ate.

5. Change your lens. Food logging is about gathering data and having a record to look back on. Not losing weight? Ask your doctor or a dietitian or health coach to review your food log with you to see where you might be able to make changes. Feeling lethargic? Consult your food log to see if you ate bigger portions or more high-glycemic carbs or perhaps drank more alcohol than usual. You can put more pep in your step by playing around with your macros (the amount of carbs, protein, and fat you eat) and by adding more energizing sources of whole foods (like fresh fruits and veggies, oatmeal, matcha, etc.) Yes, food logging can be tedious at times but it also lets you play food sleuth so you can start learning more about how your body responds to different foods and food combinations.

If you’re looking to improve your health, tracking your food intake is a great way to start. There are many different ways to track what you eat, and Signos offers a program that allows users to gather insights based on food tracking and glucose spikes. By understanding how different foods affect your body, you can make better choices about the foods you eat—which will help you reach your health goals.
