When eating flaky biscuits, watch your portions because the calories can quickly add up. Stick with only eating one biscuit to manage your calorie consumption, and make sure to use portion control when adding butter or other condiments.
The calorie in a biscuit depends on the size. A 4-inch diameter biscuit contains 357 calories, a 2 ½-inch diameter contains 212 calories and a 1 ½ -inch diameter contains 49 calories. Fifty percent of the calories come from carbohydrates, 8 percent from protein and 42 percent from fat.
