Energy balance

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.

Focus on increasing your daily non-exercise movement. This includes standing, walking to work, fidgeting, and doing chores. These activities collectively burn significantly more calories than structured exercise for most people. To manage weight, ensure your daily environment encourages movement rather than sedentary convenience.

GoodSupportsHIGH confidence
It appears that changes in NEAT subtly accompany experimentally induced changes in energy balance and are important in the physiology of weight change. ... Those individuals who increased their NEAT the most gained the least fat with overfeeding, and those individuals who failed to increase their NEAT with overfeeding gained the most fat.

Why this rating

Based on controlled overfeeding studies in humans (twins and lean subjects) showing strong correlations between NEAT modulation and fat gain.
