1. A study found that when people eat a wide variety of foods, they eat more, and fast food companies make it cheaper to buy "meals" than to buy them on a single basis. In other words, if you have French fries and chicken chips, you may burn more calories than simply eating more chicken chips. They lick it with their fingers - good words. Believe it or not, some words will make us drool. According to time magazine, a study found that 28% of consumers were more willing to buy beef labeled "high quality"; another study found that fast food companies are increasingly using the word "snack" on their menus to let people eat beef during non dinner time. Dr. Brian Wansink, author of slim by design: unconscious diet solutions in daily life, is an authoritative expert in diet behavior and food marketing. He told men's health magazine that using descriptive keywords has a significant impact on how we think about eating experience. Three. They put up billboards and other advertisements everywhere to attract your attention. A 2013 UCLA study found a correlation between fast food advertising and obesity. " Previous research has found that fast food advertising is more common in low-income, ethnic minority areas, and laboratory research has shown that marketing can make people eat more, "said Leonard leser, M.D., a research doctor at the Palo Alto Medical Foundation Institute in California. The study shows that there's a special relationship between outdoor advertising (an annoying billboard with pictures of your favorite Mexican pancakes) and obesity. According to the Huffington Post, these companies spend the second largest amount of money on outdoor advertising after TV advertising. The smell of fresh bread in the air? It's totally artificial. There is nothing more appetizing than the smell of chips or cinnabar in the air. When we are hungry, our body's sense of smell increases. It's obviously a two-way street. According to a study published in the journal Obesity, external stimuli such as smell can increase our ghrelin production, a hormone that controls our hunger. Cinnabar uses this phenomenon to heat cinnamon slices in an oven near the store to produce a drooling smell, the Huffington Post reported. Panera bread also adopted a similar strategy, baking bread during the peak consumption period.

5. Fast food should be convenient. When Americans decide what they want for dinner, convenience takes a high place in their priority list. A 2010 study by the National Center for health statistics found that obesity rates were similar across all income and education levels. In fact, fast food is most popular among middle-income people. This means that contrary to popular opinion, people usually don't turn to fast food because of the low price. Instead, Americans are looking for convenience. And, as Stanford University writes, one reporter estimates that nearly 20% of American meals are eaten in cars. KFC and other chain stores take advantage of this to launch products such as "go Cup", which is specially designed for cupholders.

6. When you think of fast food, you feel in a hurry. There is a reason why I always feel in a hurry to go to McDonald's. A series of psychological studies reported by the new york times show that when people think of fast food, they will feel more hurried, less likely to taste an experience, and less likely to leave the leftovers for tomorrow. Another study shows that when you feel rushed and eat fast, you are more likely to become obese. According to Ian MacDonald, a professor of metabolic physiology at the University of Nottingham, eating too fast can damage the sense of fullness in the brain. And about 20 minutes after you start eating, your stomach tells your brain it's full. At that time, as long as you can eat the number of crispy chips, this possibility is too terrible.

7. Fast food companies target children.

fast food companies don't just think about the present and the present. A Yale Rudd Center study found that in 2013, children watched an average of 13 food ads a day, 23% of which were for fast food restaurants. That's important, according to the Huffington Post, because a 2012 study concluded that teenagers familiar with fast-food television advertising are more likely to be obese. In addition, according to a report on Fox 31 in Denver, another study shows that "fast food advertising for children is more likely to include toys and gifts", attracting children. By contacting children in their early lives, these companies will instigate habits that may continue.
