According to the Daily Mail, Burger Kings Smoked Bacon and Cheddar Double Angus, which contains 966 calories, is the most fattening burger on the high street, with twice as many calories as a Big Mac from McDonalds. The snack is made up of 2 6.4oz beef patties, bacon, cheddar, lettuce, onion, tomato and mayonnaise, finished off with a steakhouse sauce. In calorific terms, thats worse than drinking 4 pints of lager, eating 5 chocolate bars or gorging on 13 digestive biscuits in one sitting. If you felt guilty afterwards, you would need to jog 5mph for at least 90 minutes in order to burn off the calories.
