There are 56 calories in 1 thin slice of Roast Beef. Calorie breakdown: 60% fat, 0% carbs, 40% protein.
Fats have more than twice as many calories as protein -- 9 calories per gram. So for an 1,800-calorie diet, you can have a maximum of 180 calories from saturated fat, or 20 grams. Beef ribs are the worst offender. Four ounces have more than 13 grams of saturated fat. Beef chuck roast offers more than 11.5 grams of saturated fat, while round roast is much leaner, providing about 7 grams of saturated fat. If youâre making beef patties, opt for ground beef that is at least 80-percent lean. Four ounces of 80-percent lean beef provide 7.5 grams of saturated fat.
