Answer:
Certainly, external stimuli can trigger feelings of hunger even if you don't have a physiological need for food at that moment. Here are two common external stimuli that can do this:
1. **Sight and Smell of Food:** Simply seeing or smelling delicious food, whether it's a commercial on TV, someone cooking nearby, or passing by a bakery, can stimulate your appetite and make you feel hungry.
2. **Social Eating and Peer Pressure:** When you're in a social setting or at an event where others are eating, the act of seeing people around you enjoy a meal or snack can lead to a psychological desire to join in, even if you weren't hungry before.
These external cues can influence your eating habits and sometimes lead to eating when you may not actually need to satisfy hunger. It's important to be mindful of these triggers and differentiate between true hunger and the desire to eat prompted by external factors.
