Frequently Asked Questions:

1. Can a fitness tracker help me lose weight?

A fitness tracker can assist you in weight loss. The tracker does not help with weight loss if you do not include exercise and diet improvements

While the fitness tracker can remind you to get moving and help you track your food intake, it is up to you, the person wearing the tracker, to start making life changes to improve weight loss.

2. How to use a fitness tracker to lose weight?

A fitness tracker can improve weight loss by reminding you to improve your movement throughout the day, set goals, monitor your heart rate, and get accountable.

To lose weight using a fitness tracker, you need to make sure you have the right fitness tracker. Some trackers offer a large amount of data, while others focus on specific exercise styles. 

Do the research to make sure your fitness tracker is great for the type of exercise you prefer, like running, swimming, or biking. 

Once you have your tracker set up, customize your daily and weekly goals. Ensure you also turn on movement reminders and give the tracker a chance to be your accountability partner. 

Your tracker likely comes with a social community. Use it to add friends that will help you improve your daily movement. Use the community to motivate yourself. Even small movements throughout the day can improve your health.

3. Can a smartwatch/fitness tracker count calories? 

Each fitness tracker and smartwatch measures calories in a slightly different way. The trackers use an accelerator and gyroscope to measure the movement your body is making. The tracker then calculates calories based on the information you provide the system. 

The system uses your base metabolic rate (BMR), which is the calories to keep your body working at rest. The system needs your weight, height, age, and gender to calculate this rate. 

Once your BMR is calculated, the system has a specific calculation that puts your movements and base rate together to create a caloric output. One of the best fitness trackers for losing weight and having the most accurate calorie counters is Fitbit Sense. 

4. How accurate are calorie counts on fitness trackers?

Fitness trackers are not 100% accurate. Many studies done by different universities (Including Stanford) have proven that different trackers will overestimate and underestimate different activities. Many companies that make the products also state in fine print that their product is not 100% accurate. 

The heart rate monitor on most fitness trackers has been proven to be accurate. 

The Stanford study found that calorie counts, on average, were inaccurate by 25% or more.

5. What are fitness trackers missing? 

Fitness trackers are missing customization. Many fitness trackers have numerous data points for each person, including: sleep, exercise, periods, food, stress, and overall health.

The problem with fitness trackers (and their apps) is not every person needs each data point. At some point, the data can be overwhelming. 

As more data points are added, like meditation and stress relief, it becomes more critical for fitness trackers to allow the user to customize their experience within the apps and on their tracker.
