Answer:
- Affecting digestion.
Step-by-step explanation:
Based on the excerpt given in the question, the speaker is pointing out the effects of having fast food regularly in our daily lives. Aside from the physiological effects, it can also have psychological impacts in the individual. When the body is purged of fast food after it's already used to it, it becomes healthier and more better. But that is not something that happens smoothly. The person may develop a serious reluctance to adapt to the new eating regime, affecting the body both psychologically and physically. This kind of remission will make it harder for the person to feel normal, like a drug addict unable to stop himself. The use of the word physiological means the effects on the digestive manner of the person.
