How activity fits into your daily calorie needs
This tool adds the energy your selected activities use above rest. It can include everyday movement (NEAT) and planned workouts (EAT), but only the activities you enter. It does not measure every movement in a day.
Non-exercise activity thermogenesis (NEAT)
Walking around, standing, chores and commuting can contribute substantially to daily activity energy. The separate NEAT Calculator focuses on those non-exercise activities and includes a fuller guide to NEAT, EAT and PAL. [Source 1][Source 2]
Exercise activity thermogenesis (EAT)
EAT refers to structured exercise such as running, cycling or strength training. In Daily mode, enter the activities from one day. In Weekly mode, enter the minutes per session and how often each activity happens; the daily average then spreads that weekly total across seven days. Avoid entering overlapping activities twice.

Physical Activity Levels (PAL)
PAL is a shortcut that scales resting energy to estimate overall daily needs. It already includes ordinary movement and exercise, so adding these activity calories to a PAL-based TDEE would count movement twice. If you have a reasonably complete activity estimate, transfer its daily value to the TDEE Calculator’s manual activity mode and add any other activity there. Otherwise, the PAL mode provides a simpler starting estimate. [Source 1][Source 2]
