The fast food meals with the biggest calorie counts

Whether it's a Friday treat, a drunken craving, or you're addicted to the deliciousness, everyone knows fast food is rarely a healthy option. But even within this broad church of gluttony, these foods are the worst offenders.

McDonald's, KFC and Domino's are among the best-known companies which offered the food with the highest calories to UK customers.

The good people of News.com.au went through some of the most popular meals. Here's a break down of all the badness within the tasty goodness, in ascending order of calorific content:
