Food that burns fat is a hit on Internet. Find your own resources by searching with google.
I found this one : "So though certain foods help you to burn a greater number of calories than the calorie value of the food itself, thus resulting in a possible weight loss"
Or this one: "Fat burning foods are foods that burn more calories than the calorie content of the foods itself. "
Or read another approach to fat burning food here: "Yes, some foods have been shown to help people lose fat, but it is typically because the food is either low in calories or satiates their appetite. "
