How calculations work

A plain-language guide to the estimates and measurements shown in Limvia.

Important medical disclaimer

Limvia is not a medical device or medical tool.

Limvia does not provide medical advice, diagnosis, treatment, emergency support, or professional health guidance.

All calculations and estimates are for personal tracking only. They may be inaccurate or incomplete and must not be used for medical decisions.

Activity calorie burn

If you enter measured calories from a watch, fitness device, or another source, Limvia uses the value you entered.

If you click Estimate calories, Limvia estimates calories from MET values, your latest saved body weight, and the activity duration.

estimated kcal = MET x body weight in kg x duration in hours

MET means metabolic equivalent of task. It is a general way to describe how much energy an activity uses compared with rest.

When height, latest weight/BMI, age, and sex are available, Limvia uses corrected MET logic to adjust the standard MET value for personal characteristics. If those details are missing, Limvia uses the standard MET value.

MET estimates are general approximations. They are not individual measurements and can differ from your real energy use.

BJJ and strength sessions

For BJJ, Limvia estimates practice time and live rolling time separately. Total session duration is treated as the whole session. Roll time uses the roll intensity when you enter it.

For strength sessions, Limvia uses the estimated calories saved on logged sets and adds those set estimates to the activity.

Other measurements

  • Weight and body metrics are values you enter yourself.
  • Steps are values you enter yourself and can be used for movement estimates.
  • Food and drink calories are entered by you or filled from app defaults where available.
  • Dashboard burned calories combine estimated base energy, movement or steps, and logged activity calories when enough profile data exists.

Sources used for calorie estimates

Limvia uses MET values based on the 2024 Adult Compendium of Physical Activities and the Compendium corrected MET explanation for personal adjustment.

These sources help standardize estimates. They do not make the result medically precise for an individual person.
