Bagels come in different sizes, and depending on the size, a bagel can amount to a significant portion of your daily caloric intake. If you add a serving of peanut butter to a bagel, the calorie content increases dramatically.
There are 190 calories in one 2-½ ounce bagel. A 2-½ ounce bagel with 2 tablespoons of creamy peanut butter on it contains 380 calories. A 4-ounce bagel with 2 tablespoons of creamy peanut butter contains 479 calories, and a large bagel with 2 tablespoons of creamy peanut butter contains 550 calories. Two tablespoons of creamy peanut butter contains 140 fat calories.
An average size 100 percent whole-wheat bagel contains 277 calories. An average size bagel that is not 100 percent whole wheat contains 300 calories. There are 288 calories in an average size raisin bagel.
To decrease your caloric intake, eat only half a bagel and use less peanut butter. Since half of a 4-ounce whole-wheat bagel contains 138 calories, eat only that half and put one tablespoon of peanut butter on it for a total of 233 calories. For fewer calories, spread ½ of a tablespoon of peanut butter on your bagel.
