mate of mine and one of his friends publicly discussing whether toast has more calories than bread 
floored me man, not only that i'm loosely associated with one of them but just generally, in terms of what it means for the human race long term 
The process of cooking breaks chemical bonds. If you keep cooking bread, it will eventually turn to ash. This has very few, if any, calories. Energy is released from breaking bonds. We measure this in calories. If toasting has already broken some bonds before you eat it, then shouldn't there be theoretically fewer bonds to break during digestion than if you ate untoasted bread? The more you toast bread, the fewer calories?
