The weight gains were 180 vs 280 grams. While that is a significant difference, I still think calorie counting gives a useful estimate, since people eat many foods and the error reduces in aggregate, as some are overestimated and others are underestimated. In addition, people are not rabbits and may have evolved digestive systems better adapted to reheated fats since the invention of cooking (evidence of campfires 1-2 My ago).
