For some people, keeping track of food and calorie intake can be helpful for promoting weight loss.

Research shows that people who log calories lose more weight and are more likely to keep the weight off in the long run (1, 2).

These days, counting calories is very easy. There are many useful websites and apps that help you log your meals and track your intake.

Most are accessible online, and signing up takes less than a minute. All these apps are available for:

Plus, most offer at least a basic version for free.

This article reviews the 8 best calorie counters available today.

While logging calories can be a helpful weight loss tool for some, it’s important to note that tracking food and calories can lead to unhealthy behaviors such as food obsession and disordered eating patterns.

Tracking foods and logging calories are not always necessary for healthy weight loss. If you’re trying to gain or lose weight, it’s important to find methods that are effective and don’t have a negative impact on your physical or mental health (3, 4).

Here’s what we took into account to select the best calorie counter apps:

MyFitnessPal is one of the most popular calorie counters right now.

It tracks your weight and calculates a recommended daily calorie intake. It also has a well-designed food diary and an exercise log.

The home page provides a clear picture of how many calories you’ve consumed during the day. In addition, it shows your remaining recommended intake and how many calories you’ve burned by exercising.

If you’re using a fitness tracking device, MyFitnessPal can likely sync with it to include its data in the exercise log.

The app tracks your progress toward your goals and offers chat forums with fellow users. The forums include:

MyFitnessPal’s nutrition database is extensive, containing more than 11 million foods. You can also download recipes from the internet or create custom foods and dishes.

The app even saves your favorite meals for convenient logging.

Additionally, MyFitnessPal’s barcode scanner allows you to enter the nutritional information of some packaged foods instantly.

Each day is presented as a pie chart, showing your breakdown of carbs, protein, and fat. You can also write a note for each day, recording how things went or how you were feeling.

MyFitnessPal does offer a free version. However, some features are available only in the premium version, such as:

Noom is not only a calorie counter but also an app designed to help you lose weight and sustain weight loss using psychological approaches such as cognitive behavioral therapy.

The app asks for specific information, such as your:

It uses this information to create a calorie budget — an estimate of the number of calories you should consume each day. It then uses your calorie budget to help you reach a calorie deficit.

Noom encourages you to track the number of calories you consume each day and to check your weight at least once a day.

It also helps you create diet plans without limiting or restricting certain food items. Instead, the app focuses on calories and nutrients as a way to promote weight loss.

Noom’s price varies depending on the length of the suggested plan. No free version is available, but it does offer a free trial.

Lifesum is a calorie counter app that focuses on teaching you how to lead a healthier lifestyle.

Aside from tracking your calories and macros, Lifesum provides a food and meal rating system that explains whether a food is nutritious and whether your meal is healthy or unbalanced.

However, no food is off-limits, and the app uses constructive language that does not categorize foods as “good” or “bad.”

In addition, Lifesum tracks:

It adjusts your daily calorie goal based on calories burned during physical activity.

The app provides:

MyNetDiary even allows you to import recipes and calculate their nutrition information.

The premium version also tracks micronutrients and grants you access to:

If you’re looking for the simplest calorie tracker app, then Calory may be just the one for you.

With Calory, you can log either calories or foods, but it tracks only your calorie intake.

The home page displays a bar chart with the percentage of calories consumed and remaining calories for the day, which the app calculates when you set your goals. However, you can also manually customize your calorie target.

The history tab shows a breakdown of the foods and calories consumed per meal, along with weekly, monthly, and yearly charts of your total calorie intake and weight changes.

Calory’s food database is linked to the U.S. Department of Agriculture (USDA) food database. Logging your food is relatively easy, although the database may be tricky to use.

Additionally, the app saves your most recent food logs and provides a list of common foods to make future entries easier.

Upgrading to premium unlocks macro and water tracking, a barcode scanner, recipes, and access to a premium food database.

Trying to “do it right” when it comes to nutrition may feel tempting, but it can backfire.

If you are preoccupied with food or your weight, feel guilt surrounding your food choices, or routinely engage in restrictive diets, consider reaching out for support. These behaviors may indicate a disordered relationship with food or an eating disorder.

Disordered eating and eating disorders can affect anyone, regardless of:

They can be caused by any combination of biological, social, cultural, and environmental factors — not just by exposure to diet culture.

Feel empowered to talk with a qualified healthcare professional, such as a registered dietitian, if you’re having a hard time.

You can also chat, call, or text anonymously with trained volunteers at the National Eating Disorders Association helpline for free or explore the organization’s free and low cost resources.

Calorie-counting apps and other self-monitoring technologies are great tools that allow users to monitor their food intake and dietary choices.

While most research on the impact of calorie counter apps and body weight centers on their beneficial effects for weight loss, some studies also point out other highly valuable benefits.

For instance, food logging may also encourage behavior changes that help modify unhealthy habits — one of the main goals of nutrition interventions (5).

In addition, just as it recommends a maximum number of calories to consume to reach your target weight, a calorie monitor can help you find out whether you’re eating too little, which could cause your resting metabolic rate (RMR) to slow down after weight loss (6).

Your RMR is the number of calories your body burns at rest. A slowing of this rate helps prevents excessive weight loss, which may lead to weight regain (6).

Lastly, some apps also provide accountability, which is key when aiming for consistency, a determining factor for weight loss success (7).

Aside from helping you reach your weight goals, calorie-counting apps are a great tool to help you modify unhealthy habits and find out whether you’re eating too little or too much. They also provide accountability, which helps with consistency.

Here are some important factors to consider when choosing a calorie counter app:

Most people have a negative perception of the word “calorie,” but a calorie is simply a unit of measure for energy.

A splash of milk in your coffee might have 5 calories — that’s 5 energies, in other words. If you consume enough energy, your body uses it as fuel. If you consume more energy than your body needs, your body stores the extra.

Scientifically, a calorie is an estimate of the amount of energy required to raise the temperature of 1 gram of water by 1 degree Celsius. You consume calories through food, and they provide you with energy to maintain life and fuel physical work (8, 9).

The calories you consume each day make up your calorie intake, while the ones your body burns through physical activity, digestion, or basal metabolic rate are your calorie expenditure (10).

“Energy balance” is a term used to indicate that your calorie intake matches your expenditure. According to the “calories in, calories out” paradigm, energy balance helps maintain your body weight (9, 10).

But weight loss is sometimes difficult because your body has mechanisms to protect you from losing weight.

A calorie deficit can lead to weight loss, while a calorie excess or surplus leads to weight gain (9, 10).

You can reach a calorie deficit by reducing your calorie intake or increasing your expenditure — or both. In contrast, you can create a calorie surplus by increasing intake, reducing expenditure, or both.

Research shows that calorie counting by logging your food intake may be a helpful weight loss strategy because it helps increase awareness of current and desired eating behaviors (1).

However, studies also note that people who use apps to self-monitor diet and physical activity are more likely to engage in disordered eating behaviors (11, 12, 13).

Counting calories may be especially unsafe for people with a history of disordered eating.

In fact, one study found that calorie-counting apps may increase the desire to be underweight, and some users even acknowledge the apps’ role in worsening their disordered eating behaviors (12).

If you’re concerned about safety, shifting the focus from counting calories for weight loss to eating intuitively to improve well-being may be a healthier and more beneficial approach in the long run (14).

Among weight loss apps, one such as Noom may be preferred because it focuses on the psychology behind personal food consumption and making lifestyle changes.

Calorie counter apps often have millions of foods to choose from, with different available serving sizes to match what’s on your plate. But they are not 100% accurate for multiple reasons, which ultimately come down to human error.

Food logging requires time and effort. While technology has made it easier, the process still relies on users’ discipline — and even their memory, if they log their intake afterward.

Additionally, users may incorrectly track their food intake, either by inaccurately logging or estimating amounts or by neglecting to track some ingredients, which may add or subtract calories from their calorie budget.

Restaurant food preparation methods can vary greatly as well. Chain restaurants will often have calorie and nutrition information on their websites and on actual menus.

Before calorie counter apps existed, people used multiple techniques or tools to account for a day’s worth of calories. You may want to try one of these if you find calorie-counting apps too tedious or burdensome.

Common tools include (15):

Still, keep in mind that whether you rely on an app or not, calorie counting is more of an estimation than an exact measurement. In either case, it will take practice and patience to improve your estimates.

Calorie counting apps may be safe for some people but are not recommended for those with a history of disordered eating. They’re also not 100% accurate, primarily due to human error. You can always try other tools to estimate your calorie intake.

Calorie counters and nutrient trackers are incredibly useful if you’re trying to lose, maintain, or even gain weight.

They can also help you make specific changes to your diet, such as eating more protein or fewer carbs.

However, there is no need to track your intake constantly.

You can try tracking it occasionally or for a few days or weeks to get a more nuanced view of your diet.

That way, you’ll know exactly where to make adjustments to achieve your goals.
