External eating cues include which of the following?

• A. Smells
• B. Hunger From Energy Deficit
• C. Hormonal Changes Signaling Fullness
• D. Digestive Enzymes

Answer: (A)

External eating cues are environmental signals that nudge us to eat, such as the smell of food in the air. Smells can strongly influence appetite by activating brain reward pathways and triggering craving and salivation, even if you aren’t physically hungry. The other options describe internal processes: hunger from energy deficit is an internal cue signaling the body needs calories, hormonal changes signaling fullness are internal satiety signals, and digestive enzymes are part of digestion after eating. So the smell of food best fits the idea of an external cue.
