For most people, a daily diet containing 2000 calories of energy (actually 2000 kilocalories, but never mind) is about right. Many dieters survive on 1200 calories a day. You can get that from a single large Burger King Old Fashioned Ice Cream Shake -- which also contains more than two days' worth of the recommended intake of fat. That single drink also has more calories and fat (42 g) than a Double Whopper with cheese (1150 cal, 33 g of fat).
Pick a Double Whopper Value Meal, and you're up to 2100 calories, and approaching a week's worth of fat. And if you're wondering, a Venti Egg Nog Latté from Starbucks is a bit milder -- 810 calories, and 36 grams of fat, or only a little over a day's worth, but still more than the Double Whopper with cheese.
