It's been a tough few years for the fast food industry, with the growing concern to pursue healthy eating and the rising popularity of fast casual restaurants such as Chipotle or Shake Shack, and this has seen traditional chains like McDonald's, Burger King and KFC losing customers - but it seems like Burger King's chicken fries and other strategies have boosted the company's chances.

Months after the company rolled out the classic Burger King chicken fries once again, the company's rolling out its third-quarter numbers to the world and the results are staggering, as a series of good decisions have placed the royal-themed chain back in the top.

According to CNBC, the sales boost is partly due to the return of Burger King's chicken fries, with a 6.2 percent rise in comparable sales growth, after same-sale store sales had been forecast to rise 3.2 percent and 3.3 percent for its newer addition, Canadian Tim Hortons, which allowed the chain to move its HQ to the northern neighbor.

Business Insider lists a few more reasons besides the Burger King chicken fries for the new rise of the chain (including another spicy addition, the Extra Long Jalapeno Cheeseburger) such as its efforts to simplify their menu by focusing on fewer items that create a bigger impact and expanding the franchise (besides Tim Hortons, BK is currently in talks to buy European chain Quick, which would lead to massive expansion in the Old Continent).

Still, in spite of all the Burger King chicken fries-related outcomes, the chain's still down by quite a bit from last year, with their $1.02 billion revenue declining - due to its base currency, the Canadian dollar.

According to Reuters, BK shares went up 4.4 percent as well, as the company continues to be on a roll.

With news of McDonald's getting its best quarter in years and Burger King chicken fries helping its top competitor, it seems there's still hope for the fast food industry.
