How We Ranked

Weight loss can be achieved by making positive choices in nutrition and diet, and also through increases in physical activity. As such, we decided to include a variety of devices that helped improve diet adherence, food choices, and physical activity. Beachbody UK, One You Couch to 5k, and Polar Flow encourage users to combine healthy eating and exercise as a means of losing weight – with a larger focus on physical activity. These apps provide detailed instructions on how to incorporate and increase physical activity for a healthier lifestyle, which is why they made the list.

Apps that included recipes were also important. We ranked Yummly well because it provided recipes from seasoned chefs, as well as downloadable grocery lists. This helped exceptionally busy individuals make the right food choices without having to think.

The ability to scan foods was also important, as it allowed for easy tracking. My Fitness Pal and Edo were ranked highly because of the barcode scanner that allows for individuals to scan packaged foods before consuming them. This helped improved tracking as well as minimize human input error.

Competition can be a powerful motivator, which is why we included FitYou. FitYou encourages multiple users to share their efforts and motivations to stay healthy by creating fun exercises and challenges geared toward group participation.


Weight loss apps assist people in adopting healthy lifestyles. Most of us would prefer to live healthier lifestyles, but assistance is often needed in making the right choices. The use of a weight loss app is a convenient method of monitoring health-related choices. Regardless of other activities, users can monitor their health and the foods they consume at any point of the day. One 2015 study found that mobile phone weight loss apps can be a useful tool for weight loss (1).

Weight loss apps can be chosen based on an individual’s needs and wellness goals, so they offer flexibility and a level of personalization, which may improve adherence to a healthier lifestyle.

Weight loss apps are easy to access: Weight loss apps are available for download on pretty much all devices and are accessible 24/7. A 2017 study found that weight loss app users value simplicity, the availability of multiple features, data storage, and ease of function (2).

As long as you have your device, it is charged, and you have internet access, the weight loss app is ready to go.

Weight loss apps may help to improve health outcomes. Many individuals struggle with disease as a result of their weight and their lifestyle choices. By following a proper weight loss plan through an app, users can help improve dietary adherence and weight loss outcomes. 

Weight loss apps may help create positive changes in body composition. With most weight loss applications, users are able to improve health-related behaviors, such as monitoring the caloric content and nutritional value of foods. One study showed that mobile health interventions could serve as a way to improve healthy behaviors (3).

It is important to remember that weight is not necessarily the best indicator of health as it does not consider body composition, where the body fat is located, or any other health conditions that a user may have. Depending on a weight loss app’s features, there may be critical health information that is not being assessed.

Weight loss apps are affordable. In comparison to gym memberships and personal trainer sessions, weight loss apps are an affordable alternative to help people lose weight. 

Weight loss apps can help track food consumption. Weight gain may occur because most individuals don’t give much thought to how much food they consume every day, or how many calories may be contained within a particular food choice. Many weight loss apps allow users to record what food is eaten, which allows for daily calorie and nutrition information to be evaluated. By entering this nutritional data, users can readily see why they may be gaining weight because of their food choices. 

It is widely accepted that monitoring diet can lead to improved weight loss success. One study suggests that smartphone apps that monitor dietary choices can serve as a practical tool for individuals who want to achieve weight loss (4).

Weight loss apps can provide accurate nutritional information. The benefits of using a weight loss app is not just to assess the number of calories present in a food, but also to provide guidance on healthy food choices based on their nutritional value. A research study conducted in 2018 suggests that weight loss apps that include features on nutrition can complement the nutritional care delivered by dieticians and improve adherence to behavior changes (5).

A positive change in eating behavior, guided and reinforced by a weight loss app, may improve the user’s opportunities for weight loss. If your goal is to determine the nutritional appropriateness of your diet, ensure that the weight loss app you choose has the necessary features. If you have specific concerns or questions about the nutritional value of food, or if you require specialized guidance on nutrition choices, it may be appropriate for you to consult your healthcare provider, a registered dietician, or registered nutritionist.

Weight loss apps may make you more aware of the food you eat. By tracking your food in weight loss apps, you can become more aware about the nutritional and caloric contents of the food you eat. This can help you make better choices and help you asses any food intolerances you may have. 

Side Effects

Weight loss apps are not a quick fix. Many weight loss app users incorrectly think that the use of the app will result in weight loss, and in a short amount of time. However, this is not true as the weight loss app is only effective if the user adopts positive lifestyle changes. As a tool, weight loss apps do not cause users to lose weight without making better food choices, reducing caloric intake, and increasing physical activity.

In order for weight loss apps to have a positive effect, they require the conscious effort of the user, as well as time to create the desired change. A weight-loss app is not a substitute for better lifestyle choices but serves instead as a tool to guide and record positive lifestyle choices. Consideration should also be given to the user’s motivation to lose weight, the social support a user has in their weight loss journey, and their ability to adhere to positive lifestyle choices.

Weight loss apps may not be completely accurate. Weight loss apps are one tool that may be useful in tracking calories and food intake. But, there is no certainty that nutrition and caloric calculations are 100 percent accurate. A 2015 study showed that many weight management apps lack the quality required to provide completely accurate nutritional data and that more research is required to determine the effectiveness of weight loss apps in weight management (6).

Weight loss apps can be a distraction. Users may find that they are checking on their weight loss data more than is necessary, leading to distraction from other matters. Too much emphasis may be given to the app itself, and any potential changes in weight, rather than focusing on other more productive activities. Weight loss apps are but one tool that can be used in conjunction with many other tools to achieve weight loss. Further, in focusing solely on weight loss, other positive health changes that can be achieved through better nutrition and increased physical activity may be overlooked. 

Weight loss apps are not a sustainable long-term plan. While the apps may help to initiate and develop a healthier lifestyle, it may not be suitable for users to rely on as part of a long term plan, or to use throughout their lifetime. Realistically, it may be impossible to track every single food choice that is consumed daily or to adhere to exacting food choices at all times. 

Even with a concerted effort, it may prove difficult for even the most diligent person to maintain the eating habits suggested by a weight loss app. The conclusion of one research study found that many weight loss apps would be more helpful to users if the apps included more strategies on motivation and other behavioral change strategies (7). Similarly, adhering to a particular diet for an extended period of time may exclude foods that contain essential nutrients that are recommended for healthy living. This is partially why it is best to consult with your doctor or a dietitian.

Weight loss apps may have a negative psychological effect on an individual. Some individuals who make use of weight loss apps may set unrealistic or unhealthy weight loss goals for themselves, which may cause some health risks. One study set out to understand the potential impact of weight loss apps on disordered eating behaviors. The researchers found that some participants acknowledged that apps worsened some negative eating habits (8). 

Weight loss apps may emphasize weight over health, and calories over nutrition. While users of weight loss apps generally want to achieve some amount of weight loss, it is important that it is done in the appropriate manner and as part of a healthier lifestyle. Eating healthy involves enjoying nutrient-dense food in appropriate portions. Many individuals have specific and complex dietary needs, so a weight loss app may not be appropriate for their lifestyle.

Concentrating solely on numbers (weight or calories) should not substitute healthy eating and regular physical activity. This type of narrow focus may be detrimental to overall health, especially in special populations. There may be many situations where a weight loss app may not be appropriate, such as pregnancy, certain diseases, during medical treatment, and during childhood.

Weight loss apps may not provide accurate nutritional information on all foods. The nutritional information of every single food or meal is not contained within every weight loss app. There are simply too many foods and food combinations that would need to be contained with the app. Because of the limited data held within weight loss apps, their practicality while dining out may negatively impact the user’s ability to make sound food choices. However, some apps do offer the ability to input ingredients used. 

Recommended Usage

Weight loss apps can be used as often as one needs. You may need to consult a medical practitioner to ensure weight loss apps are an appropriate tool in weight management for your desired goals.

For the best results, you should use them every day to track food, calories and exercise. This will ensure you are sticking to the plan and tailor it to how your progress is going. Using weight loss apps intermittently will not yield the best results, especially if it’s for the purposes of weight loss.
