I’d say everyone is different as far as losing fat from different parts of their bodies. Many personal trainers will tell you that you cannot “spot train” certain areas of the body to remove fat from them (I.e. Doing crunches will not remove fat from your stomach). Of course I couldn’t conceive of how to “spot train” your fat pad in the first place. Anyways, I’d say get a good cardio workout and eat right and you’ll be able to lose that weight in no time (especially given the motivation to lessen that fat pad).
I haven’t read anything specifically but I think one would see a similar reduction with fat pad as with abdominal fat since they are in the same “area”. I’d focus on building muscle in the “core” of your body (leg lifts, crunches, situps, etc) since those muscles also tend to burn fat when you’re not doing anything.
Ok, sorry this turned into a “how to workout” post. I’m not sure how much reduction you’d see, but I’d say you’ll definitely see a difference - 8-10% body fat is pretty low so I’d say depending on your build you’d only have a cm or two of fat pad left at most (depending on where your body stores it’s fat).
