Every fast food restaurant is now aware of the problem that every nation is currently encountering. In fact, the tendency to consume healthy products with a low level of fatty acids and cholesterol is growing. Therefore, major fast food industries, such as McDonalds, Subway and Jack in the Box, adhere to new international standards to gain a competitive advantage. Although fast food is not out of fashion, people still try to buy a quick but healthy breakfast due to the peculiarities of leading a working life. At this point, all restaurants begin to pay attention to food quality, healthy diet and nutrition to address the problem of obesity and excess weight. To understand the differences and similarities between the identified initiatives, it is worth paying attention to aspects such as food quality, service delivery and pricing cost. So, a quick look at restaurant policy reveals that all businesses pay attention to healthy eating policy by promoting nutrition plans and taking care of customers' calorie intake.

The restaurant also takes care of those who care about calorie intake and, for this reason, some of the dishes offered correspond to the needs of a healthy diet. Jack in the Box lags behind the other two restaurants in terms of service due to the absence of some features, such as Wi-Fi zones, a lack of waiters and huge queues. However, it is compensated by high-quality food and drinks. Since the restaurant adheres to an innovative growth strategy, its pricing strategies are also sophisticated.

Overall, the pricing strategy is not as distinct compared to other restaurants.
