Energy expenditure is the amount of energy (calories) your body uses throughout the day for basic functions like breathing and circulation, as well as for movement and exercise. In the app, it helps determine your daily calorie goal and how it’s calculated, depending on your selected settings:
If you like having a specific calorie goal number, use the Estimation mode, which sets your goal based on the answers you provided during the onboarding quiz. With this mode, you aim to eat the same fixed number of calories each day, regardless of how active you are, since you’ve already specified your activity level during the onboarding quiz.
If you prefer your calorie goal to adjust based on your workouts, use the Activity Tracking mode. In this mode, your calorie goal starts lower but increases each time you log an activity, meaning you’re encouraged to eat back the calories you burn through exercise. Because your activity level can change daily, your calorie goal will also vary from day to day. For example, if your goal is 1,200 calories and you burn 400 calories walking, your new goal will update to 1,600 calories after logging that activity.
To change the Energy Expenditure mode:
Tap your "Profile" in the upper-left corner.
Scroll down to "Energy Expenditure" and tap it.
Select the desired calculation mode.
Once enabled, the app will automatically adjust your daily calorie goal.
