People often recommend small changes for improving health outcomes such as taking the stairs instead of the escalator or intentionally parking further away from a store in a parking lot. These changes would most directly affect which of the following?

• A. EAT.
• B. NEAT.
• C. TEF.
• D. BMR.

Answer: (B)

Verified step by step guidance

1. Understand the terms provided in the options: NEAT, TEF, and BMR. NEAT stands for Non-Exercise Activity Thermogenesis, which refers to the energy expended for activities that are not formal exercise, such as walking, fidgeting, or taking the stairs. TEF stands for Thermic Effect of Food, which is the energy required to digest, absorb, and metabolize food. BMR stands for Basal Metabolic Rate, which is the energy expended to maintain basic physiological functions at rest, such as breathing and circulation.
2. Analyze the scenario described in the problem. The actions mentioned, such as taking the stairs or parking further away, involve small, everyday physical activities that are not part of structured exercise routines.
3. Determine which term best aligns with the described activities. Since these actions involve energy expenditure from non-exercise activities, they are most closely related to NEAT (Non-Exercise Activity Thermogenesis).
4. Eliminate the other options. TEF is related to food digestion and metabolism, which is not relevant to the described activities. BMR is related to resting energy expenditure, which also does not apply to these physical activities.
5. Conclude that the correct answer is NEAT, as it directly relates to the energy expended through small, non-exercise physical activities like those described in the problem.
