          When deciding which weight loss app is right for you, there are a few factors to keep in mind, such as:

          • Budget: Many weight loss apps have a free version as well as the option to access premium features for an additional cost. Others require a subscription or a one-time purchase for use.
          • Special features: It’s important to consider the features you want an app to have, such as one-on-one coaching, meal planning and recipes, food and activity logs, barcode scanners, or macro counting. Some apps can also sync to a wearable device, such as a fitness watch, to make activity tracking seamless and convenient.
          • Weight and wellness goals: Certain apps may be better suited for certain goals. For example, if your goal is to lose weight by increasing your activity level, it’s helpful to choose an app that offers recommended workouts and integrates with an activity tracker.
          • Your experience level: If you’re new to exercising and healthy eating, you’ll want an app that includes plenty of beginner-level resources or even one-on-one coaching.

          While research shows calorie counting is effective for weight loss, it’s important to note that it has also been linked to an increased risk of disordered eating in certain people. Therefore, it may not be appropriate for some people (2, 3).

          What is the best free weight loss app?

          Several of the apps on our list offer a free version as well as an option to subscribe for access to premium features.

          FatSecret’s free version is one of the best, as it allows users to access nearly all of the app’s available features. Currently, the only tools that require a subscription are the meal planner, custom meal headings, and water tracker.

          If you’re primarily interested in logging your food intake and exercise habits, the free versions of Lose It! and MyFitnessPal are also worth considering.

          What are motivating factors to lose weight?

          There are many reasons you might want to lose weight, and research suggests that these factors can change throughout your weight loss journey (15).

          That being said, research has found that physical appearance and self-esteem are two of the biggest driving factors for wanting to lose weight (15, 16).

          One small study also found that acknowledgment from a healthcare professional and comfort speaking with a doctor played a key role in participants’ desire to lose weight (17).

          Other motivating factors supported by research include:

          • health-related concerns
          • illnesses
          • societal pressure
          • body dissatisfaction (18)

          Do weight loss apps really work?

          Research suggests that weight loss apps can be effective for weight loss and may even help improve lab values, such as triglyceride levels (9, 19).

          Still, keep in mind that the research is limited and inconclusive, with some studies showing no benefit of mobile apps for weight loss (20).

          Furthermore, several studies note that the effectiveness of weight loss apps largely depends on the individual’s level of engagement with the app, which appears to be low in many instances (21, 22).

          For example, some factors have been shown to affect users’ level of engagement, such as:

          • age
          • health literacy
          • socioeconomic status
          • other disparities

          In turn, these factors could make weight loss apps less effective for certain populations (22).

          Finally, keep in mind that while calorie counting can be effective for weight loss, it can also increase the risk for disordered eating in some individuals (2, 3).


          Trying to “do it right” when it comes to nutrition may feel tempting, but it can backfire. If you’re 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 gender identity, race, age, socioeconomic status, or other identities.

          They can be caused by any combination of:

          • biological
          • social
          • cultural
          • environmental factors

          They’re not caused just by exposure to diet culture.

          You can feel empowered to talk with a qualified healthcare professional, such as a registered dietitian who specializes in disordered eating, if dieting is becoming obsessive or intense.

          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.
