Wearing a fitness tracker reduces body fat in adults.

the verdict
INSUFFICIENT LEANING
Recorded sources
0 sources for · 2 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that wearing a fitness tracker reduces body fat in adults?

Unclear. Two small trials involving children and older adults found no significant body-fat or body-composition benefit from activity trackers, and one thesis notes the specific efficacy of trackers for changing activity behaviour is unknown. No retrieved source directly tests whether wearing a fitness tracker reduces body fat in adults generally.
