I don't think junk food has the same psychological or physical grip on individuals as alcohol, cigarettes, or other substances do. I haven't observed anyone going through the DTs on quitting french fries. However, we must also accept personal responsibility, which includes acknowledging that missing junk food is not a serious addiction.
Compared to fruits or veggies, junk food is more affordable. You can get a whole lunch of junk food for a few bucks. Junk food is often used as a comfort or calming substance by many individuals. Junk food is also helpful for the human brain's reward system.
People who don't get enough sleep choose to consume unhealthy meals to junk food. Lack of sleep weakens people's willpower and makes them more likely to pick unhealthy foods. We might become fatigued from a lack of physical activity and ongoing idleness. We all turn to junk food around this time, especially sweet snacks.
Drinking is said to improve the brain's sensitivity to the aroma of food. It might be difficult to resist the temptation since junk food always has the appearance and aroma of something nice. You'll just want to consume junk food more and more after you become addicted to it.
