Which has more calories, a slice of regular bread or toast?

The calorie and nutrient content of bread is about the same whether it is toasted or not. Also, it does not differ significantly between white, rye or whole wheat bread or toasts. There are approximately 66 to 83 calories per slice of bread. There is diet bread on the market, which has slightly lower calorie values, but I do not recommend diet products. I encourage people to buy regular food and control portion sizes.
