While Big Macs certainly aren't caloric lightweights, the amounts of fat, saturated fat, trans fat, sodium and cholesterol they contain are actually of greater concern than their calorie content.
Calorie Breakdown
A Big Mac contains 563 calories, 43.98 g of carbohydrate, 32.76 g of total fat, 25.89 g of protein, 8.33 g of saturated fat, 3.5 g of fiber, 1.29 g of trans fat, 1,007 mg of sodium and 79 mg of cholesterol. The calorie composition is approximately 52 percent fat, 30 percent carbohydrate and 18 percent protein.
Vitamins and Minerals
A Big Mac supplies 80.4 percent of the dietary reference intake of vitamin b12, 46.3 percent of the DRI of niacin, 38 percent of the DRI of phosphorus, 35.2 percent of the DRI of riboflavin, 32 percent of the DRI of thiamin, 25.3 percent of the DRI of folate, 24.3 percent of the DRI of iron and smaller amounts of other vitamins and minerals.
