The pics in which he's wearing the striped PJs(?) are obviously the newer ones, cause the other set is the one he posted before. As far as the fat loss itself is concerned, he hasn't lost anything visibly.
But he's doing this naturally and it takes time. Haven't checked his log and not sure if he's doing cardio or not, but what he's doing in the gym, what he's eating and what kind of cardio he's doing (if any at all) will all make a difference.
I wouldn't really take advice from FP (or anyone else for that matter) about dieting or lifting, but I always love having nerdy discussions about characters from DC and Marvel with him. FP, keep at it and hope you do get to where you want to be, physique-wise. Good luck.
