Free  global business directory of restaurants and cafes and coffee shops across the world. The Global Fast Food Restaurants industry is expected to decline modestly over the five years to 2021, primarily as a result of a volatile global economy and consumers' increasing awareness of the health risks associated with a diet high in fat, salt and sugar. Despite these obstacles, the industry has experienced steady and growing demand from emerging economies. The industry's attempts to respond to changes in consumer preferences have also helped diminish the decline in industry revenue. Overall, industry revenue is estimated to decline at an annualized rate of 0.2% to $797.7 billion over the five years to 2021. In 2021 alone, revenue is forecast to grow 8.4% as demand is expected to return following the spread of COVID-19
