NEAT (Non-Exercise Activity Thermogenesis)
NEAT refers to calories burned through non-exercise physical activity – such as walking, standing, fidgeting, typing, household chores, and even talking. It accounts for all spontaneous daily movement outside of structured workouts.
Difference from Exercise and BMR
NEAT is distinct from:
- Basal Metabolic Rate (BMR): Energy required at complete rest
- Exercise: Deliberate physical activity like training or sports
NEAT levels can vary widely – from 100 to over 800 kcal per day – depending on:
- Daily habits & occupation
- Stress levels & autonomic nervous system activity
- Individual disposition & unconscious movement patterns
Importance
High NEAT can significantly affect energy balance over time – influencing both weight loss and the ability to gain lean mass or maintain body weight.
