You train for an hour and sit for twelve. The hour matters — but the twelve determine the outcome, and science has given them a name.
What is NEAT?
It is the energy expended on everything that is not sleeping, eating or sports-like exercise: walking to work, typing, housework and gardening, even fidgeting[1].
The striking number
NEAT varies between two people of similar size by up to 2,000 kcal a day — because of differing occupations and leisure activities[1]. It is the main variable component of total daily expenditure, particularly in people who don't exercise at all[2].

The observed difference between people
Mayo Clinic research showed that people with obesity have an innate tendency to sit 2.5 hours more per day than their lean sedentary counterparts, and that lean sedentary people stand and move for 152 additional minutes daily[2]. The evidence supports NEAT being pivotal in regulating human energy expenditure and body weight and important for understanding the cause and effective treatment of obesity[2].
Why this matters in our lives
Because our lifestyle kills NEAT: driving everywhere, desk work, delivery for everything, and heat that keeps us inside air conditioning. The result is inactivity ranging from 50–91% per systematic reviews (the numbers).
How to raise NEAT without a gym
- Stand every half hour for two minutes — set a phone reminder.
- Take work calls standing or walking — hundreds of calories a week without noticing.
- Park further, take the stairs — two simple rules that add thousands of steps (how many are enough).
- Shop for yourself: swap one delivery order a week for a trip to the store (the delivery trap).
- Housework counts: tidying, cleaning, laundry — all genuine NEAT.
