Although organizations such as the American Heart Association recommend pursuing a healthy lifestyle rather than using a diet to lose weight, a diet can help you shed a few pounds -- provided your doctor indicates it's safe to try. It's impossible to say whether eating bread will harm your diet, given the wide range of diet parameters, but this everyday food might not be as healthy as you think.
Watch for Calories and Cravings
If your diet requires you to eat a specific number of calories per day, one or more pieces of bread might put you at risk of exceeding your calorie guideline. Bread is often high in calories. One slice of white or wheat bread has between 70 and 80 calories, which means the bread in a sandwich can account for around 150 calories. White bread doesn't provide much nutritional value and can cause a rise and fall in your blood sugar that often leads to a craving for more food. This craving, in turn, can lead to overeating. If you do decide to include bread in your diet, choose whole-grain breads rich in fiber and stick to the recommended one-slice serving size.
