“ In general, it seems that the more processed foods are the more they actually give us the number of calories we see on the box, bag or other sort of label. This applies not just to cooking and pounding but also to industrial processing. A new study this year found that in a lab experiment individual humans who ate 600 or 800 calorie portions of whole wheat bread (with nuts and seeds on it) and cheddar cheese actually expended twice as much energy, yes twice, in digesting that food as did individuals who consumed the same quantity of white bread and “processed cheese product.” As a consequence, the net number of calories the whole food eaters received was ten percent less than the number received by the processed food eaters (because they spent some of their calories during digestion). Similar work in pythons has shown that cooked and/or ground up meat also requires less energy to digest (at least for pythons). If you want more calories, whether or not you are a snake, cook, pound and otherwise predigest your food.
Fast food places could advertise the benefits of predigested foods. More calories per dollar compared to actual food.
