How was your BF% checked?  I have one of those handheld units that measures impedance or something like that.  It is not very accurate but I figure if I use it to track any reduction it would be relative.  I hear calipers are better and water tank may be the best...  You must be building muscle to have the different look. 

I had my body fat done at a gym using one of those impedance machines. At the time I weighed about 159 @ 5'8". My reading was 21%.  Wow.   Many years later, do to going to meetings, potlucks and social gatherings several times a month that always included desert, I was up to 180. When I weighed 180 a nutritionist measured my body fat percentage in her office just prior to putting me on her weight loss program. I measured 19.5% although I was 21 pounds heavier.  I can attest that cupcakes, ice cream and pie do not build muscle so I know it wasn't muscle gain. (especially since I hadn't been to the gym in a couple of years).

For most guys, the legs and butt are the first to thin out.  The last place it the torso and gut.  My legs are getting bird thin and I have no butt but my torso is still not where I want it.  While it is looking better, it still holds plenty of unwanted body fat.  We just need to keep at it.  Perhaps I will post a picture after the new year and see where I am with progress...

Congratulations!

Actually, thinking about it, you lost fat in the first 8 weeks, too.  If you stayed at 16.8% body fat but lost 8 kg, then you must have lost 16.8% of 8kg, or about 1.3kg, of fat during that time.  Sorry I didn't notice that before.

I've never had mine checked, but I doubt mine's higher than 15%, possibly as low as 9%. I'm 6'0 and 165 lbs.
