Decoding MyFitnessPal's Activity Level System
MyFitnessPal uses your profile information, including your age, sex, height, weight, and weekly goal, to calculate your daily calorie target. The activity level you select is a critical component of this equation. It determines your estimated Total Daily Energy Expenditure (TDEE), which is the total number of calories your body burns in a day. Unlike some other calculators, MyFitnessPal's activity level is based on your non-exercise daily routine, such as your job and daily movement, not your workouts. Those are added separately, so it's vital to choose a level that reflects your baseline lifestyle accurately.
The Four MyFitnessPal Activity Levels Explained
- Sedentary (Not Very Active): This level is for individuals who spend most of their day sitting. A classic example is a person with a desk job who gets very little physical activity outside of their desk. It accounts for the minimum movement required for daily life, like walking to and from the car or house. It is generally the safest baseline for most people to avoid overestimating calorie needs and then adding exercise as an extra.
- Lightly Active: This level applies to those who spend a good part of the day on their feet. Occupations like teachers, salespeople, or waitstaff who are constantly moving fit into this category. It accounts for more movement than the sedentary level but does not include strenuous or intense exercise sessions.
- Active: The active category is for individuals who spend a significant portion of their day doing physical activity. This might include nurses, postal workers, or servers who have physically demanding shifts. It factors in a higher level of non-exercise activity than the previous two levels.
- Very Active: This is the highest level, reserved for those who perform heavy physical activity for most of the day. Examples include bike messengers, construction workers, or competitive athletes whose jobs or lifestyles are highly physically demanding. This should not be selected by individuals with desk jobs, even if they exercise intensely.
How to Choose the Right Level
Selecting the correct activity level is crucial for the success of your nutrition plan. An overestimation can lead to a daily calorie goal that is too high, preventing weight loss, while underestimation can leave you with too few calories, potentially causing fatigue or hunger.
Here are some tips for making the right choice:
- Be Honest: Most people tend to overestimate their activity. If you have a sedentary job, choose that as your baseline. Log your exercise separately to increase your daily calorie goal for the day.
- Consider Your Typical Day: Think about what an average day looks like for you. Do you sit at a desk for eight hours or are you on your feet moving most of the time? Your job and daily routine are the primary factors.
- Listen to Your Body: The app's calculation is a starting point. Your actual TDEE may vary based on factors like genetics, body composition, and more. Monitor your progress over time. If you're not seeing the expected results, you may need to adjust your calorie intake or activity level.
- Connect Your Devices: For more accurate tracking, link a fitness tracker or a step counter to MyFitnessPal. This will allow the app to give you calorie adjustments based on your specific activity for the day, which is more accurate than relying on a static activity level.
Comparison of MyFitnessPal Activity Levels
| Activity Level | Description | Common Job Examples |
|---|---|---|
| Sedentary | Spends most of the day sitting with very little movement. | Desk job, video editor, receptionist. |
| Lightly Active | Spends a good portion of the day on their feet, with moderate movement. | Teacher, retail worker, salesperson. |
| Active | Spends a significant amount of the day engaged in physical activity. | Server, postal worker, nurse. |
| Very Active | Spends most of the day doing heavy physical activity. | Bike messenger, carpenter, construction worker. |
The Logic Behind Separating Exercise
MyFitnessPal's model, where you select a base activity level and log exercise separately, is intentional. The base level accounts for your basic metabolic rate (the calories your body burns at rest) and your regular non-exercise activity thermogenesis (NEAT), which is the energy expended for everything we do that is not sleeping, eating, or sports-like exercise. The calories you burn during dedicated workouts are logged separately as a caloric adjustment, allowing you to consume more food on days you exercise more. This prevents you from 'double-counting' calories burned and ensures a more accurate reflection of your energy balance.
Conclusion
Understanding what are the different activity levels on MyFitnessPal is fundamental to correctly setting up your profile and getting accurate calorie and macro recommendations. By honestly assessing your daily routine and choosing the appropriate baseline level, you can avoid common pitfalls that lead to stalled progress. Remember that your activity level represents your average day without structured exercise, and your workouts are factored in separately to adjust your daily goals. This system allows for flexibility and accuracy, helping you build a sustainable and effective nutrition plan for reaching your health and fitness goals.
