guys does burning toast reduce the calories within it?

This is way more detail than you want, so buckle up pals:

I took AP Chemistry last year, and we did what was called a "Food Calorimetry" lab. Basically, we burned food to determine the caloric value. As we all know, a calorie is a unit of energy equal to the amount of joules required to raise the temperature of water by 1 degree C. In a calorimeter, a piece of food is burned underneath a container of water. Burning food breaks the chemical bonds holding it together, and breaking these bonds releases energy, which takes the form of the heat that eventually raises the water temperature. Unless you're really curious about the rest of the calorimetry details, I'll cut to the relevant part of that statement: breaking these bonds releases energy. So, yes, technically a burnt piece of toast would contain fewer calories than a non-burnt one because of the released energy. That said, it would be such a negligible amount that it's really not worth all the carcinogens as weiomoan pointed out (happy to go on another rant about that next time on ChemTangents™). Plus it'd taste like shit. Just stick to regular toast.
