Energy balance

Nonexercise activity thermogenesis (NEAT) varies by up to 2000 kcal/day between individuals of similar size and is the primary driver of inter-individual differences in daily energy expenditure and body weight regulation.

Focus on increasing your daily non-exercise movement (NEAT) rather than just relying on gym workouts. Small changes like standing while working, walking during phone calls, or taking the stairs can add up to significant calorie expenditure (up to 2000 kcal/day difference between active and inactive people). If you have a sedentary job, try to incorporate more standing or walking into your routine, as this is a powerful lever for weight management.

ModerateSupportsMEDIUM confidence
Data support the central hypothesis that NEAT is pivotal in the regulation of human energy expenditure and body weight regulation and that NEAT is important for understanding the cause and effective treatment for obesity.

Why this rating

The paper is a review article citing observational data, twin studies, and animal models, but lacks large-scale randomized controlled trials of NEAT interventions in humans.
