What it means
NEAT is the most variable part of daily calorie burn. Two people with the same body size can differ by hundreds of calories a day based on how much they move outside the gym.
NEAT tends to fall during dieting, often without people noticing. You may sit more, pace less and take fewer steps. That quiet drop is one reason weight loss slows over time.
Tracking steps is a simple way to keep NEAT up. A daily step goal is easier to stick to for many people than extra workouts.
On a GLP-1, low energy in the early weeks can cut NEAT without you noticing. A step counter or watch makes that drop visible so you can respond. Even short walks after meals add up over a week.
Why it matters
Keeping NEAT steady helps protect your deficit as appetite and energy shift during weight loss.
