2. explain the concept of neat. how does it impact calorie expenditure?

NEAT are the calories we burn through non-exercise related activity, things like fidgeting, walking up and down a flight of stairs. It’ a small percentage of your daily caloric total but is the portion that can be changed the most easily by modifying your behavior and being more active. The more conscious non exercise based activity you do throughout the day the more calories you will burn. Walking instead of sending emails or calling, taking stairs instead of elevators, parking further away, all help to burn extra calories, lose weight, and be healthier.
