Adherence
Environmental factors, particularly occupation and urbanization, are the primary determinants of NEAT levels, with mechanization and sedentary environments drastically reducing energy expenditure.
Recognize that your environment dictates your baseline movement. If you have a sedentary job, you must consciously introduce movement (standing, walking) to counteract the environment. Urbanization and mechanization reduce NEAT, so intentional activity is required to maintain energy expenditure.
GoodSupportsHIGH confidence
The factors that impact a human’s NEAT are readily divisible into environmental factors, such as occupation or dwelling within a 'concrete jungle,' and biological factors... The combined impact of these factors explains the substantial variance in human NEAT.
Why this rating
Supported by comparative data between agricultural and urban populations, and twin studies.

More from this paper
- Nonexercise activity thermogenesis (NEAT) serves as a primary biological regulator of body weight by modulating energy expenditure in response to positive or negative energy balance, thereby counterbalancing fat gain or loss.Good
- Genetic factors contribute to individual differences in NEAT, including the efficiency of movement and the tendency to increase NEAT in response to overfeeding.Moderate
