What NEAT means
NEAT is the energy you burn doing things that aren’t structured exercise. Walking to the store, standing while talking, fidgeting at a desk, doing dishes, climbing stairs. For many people, NEAT is the single largest variable component of TDEE.
Levine’s 2002 study found NEAT varies between individuals by up to 2,000 kcal/day for people of similar age, sex, and structured activity. That’s a 50%+ swing in TDEE driven entirely by unstructured movement.
Why NEAT matters in cutting cycles
NEAT drops during a calorie deficit. The body conserves energy by reducing fidgeting, slowing movement, slumping more. Studies show 100-300 kcal/day reductions in NEAT after 2-4 weeks of sustained deficit, sometimes more.
This is one mechanism behind metabolic adaptation. The apparent “slowing metabolism” during a cut is largely NEAT compression, not BMR change. The fix isn’t necessarily eating more; it’s deliberately maintaining movement (step count target, standing desk, walks).
How to estimate NEAT
NEAT isn’t directly measurable without lab equipment. Practical proxies:
- Step count: 10,000+ steps/day = high NEAT, 4,000-7,000 = moderate, under 3,000 = low
- Activity multiplier: the “moderate” multiplier (1.55) bundles NEAT with structured training
- Daily routine description: desk job + commute = lower NEAT; teaching/nursing/parenting = higher
For coaches: ask clients about step count and standing/walking time, not just structured workouts. NEAT is where TDEE varies most.
In Coach Sheet
The Profile tab includes a Steps Per Day field that informs the activity multiplier suggestion. The Quick Stats tab notes “your TDEE estimate assumes ~X steps/day; if your real average is much higher or lower, adjust accordingly”. This makes the NEAT assumption visible rather than hidden.
