Concept
Total daily energy expenditure = resting metabolic rate + thermic effect of food + exercise + NEAT. NEAT typically dominates over exercise in absolute terms for non-athletes.
Evidence
- Sitting-time mortality signal: sitting > 8 hours/day associated with elevated all-cause mortality independent of leisure-time exercise.
- Pedometer studies: mortality falls with step count up to ~7,500–10,000 steps/day, with continuing gains at higher counts.
- Standing/walking desks: modest energy-expenditure increases; unclear whether independent mortality benefit.
Practical
- Break up prolonged sitting: stand, walk, or move every 30–60 minutes.
- Walking meetings, walking phone calls, and standing/walking desks integrate movement into work.
- Formal daily step target of 7,000–10,000 is a reasonable proxy for adequate NEAT.
Longevity relevance
Even ambitious structured exercise cannot fully compensate for 10+ hours/day of sitting. NEAT is the base-load on which formal exercise adds.
