Energy balance

Non-exercise activity thermogenesis (NEAT), defined as the energy cost of spontaneous physical activity, fidgeting, and posture maintenance, constitutes the most variable component of total daily energy expenditure and accounts for the remainder of energy needs after basal metabolic rate and thermic effect of food.

Focus on increasing your daily spontaneous movement (NEAT) like fidgeting, standing, and walking, as this variable component often outweighs structured exercise in total calorie burn for sedentary individuals. You do not need to exercise to significantly impact your daily energy expenditure.

GoodSupportsHIGH confidence
NEAT or the ‘energy expenditure of spontaneous physical activity’ encompasses the combined energy costs of the physical activities of daily living, fidgeting, spontaneous muscle contraction and maintaining posture when not recumbent, and accounts for the remainder of the total daily energy expenditure for most individuals.

Why this rating

The paper is a comprehensive review of measurement methodologies, establishing the theoretical framework for NEAT, though it does not present new primary data on NEAT's magnitude itself.
