In interpreting a research abstract that reports a 20% increase in NEAT, which interpretation is most precise?

A 20% increase in NEAT means non-exercise activity thermogenesis (standing, fidgeting, light walking) has increased by 20% relative to its baseline energy contribution, not that exercise sessions increased.

NEAT is an acronym for nutrient efficiency; therefore, a 20% increase means better absorption of calories from food.

NEAT increase implies the participant performed 20% more formal exercise sessions each week compared to baseline.

NEAT measures basal metabolic rate exactly, so a 20% increase indicates a 20% rise in BMR due to metabolic adaptation.
