Does burnt bread have fewer calories?

r/

Do we digest it if it’s burnt? Like, ash doesn’t have any calories right?

    Correct. Burned toast does have fewer. Basically the exact same energy used up when burning food is the same that you use from the food. You even produce the same waste products from burning the food as fire does. CO2 and water. Sure you make other stuff too as does the fire but those two chemicals are a product of all combustion of food.

    “In a lab, calories in food are typically measured using a calorimeter, a device that measures the heat released when food is burned. The basic principle is to burn a sample of the food and measure the resulting heat, which is then converted into a calorie value. “

    The more you burn your toast, the less calories it will contain.

    This doesn’t apply to bread due to it being simple carbs that are very easily accessible, but to foods in general: while there are technically less calories in cooked foods due to the chemical processes in cooking, more calories are available to your digestive system in a lot of foods that have been cooked
