It could simply involve how you're measuring progress. Sounds like you're just using scale weight, which doesn't account for muscle gain, fluid fluctuations, the amount of poop in your gut, water in your belly, etc. Scale weight can fluctuate around 6 pounds over the course of a single day, so...
1) Scale weight is a poor way to judge progress -- better to use tape measurements, photos, the mirror, and body comp tests. You say you're looking more defined, so it sounds like the mirror is telling you a different story than the scale.
If you must use a scale, always follow the "rules" -- weigh only in the morning, after bathroom, before eating or drinking, same scale every time placed in the same spot, naked or underwear only, and only weigh once per week on same day of the week. Weigh any other way -- too often, different scales, different times of the day etc. -- and you'll drive yourself nuts.
2) You've only been at this two weeks. Yes, I'd expect some fat loss too, and maybe you are losing fat, we don't know, but two weeks into a plan isn't really much time. And by the way, with that peri-workout plan, I would not be surprised at all if you're gaining muscle. Gain two pounds of muscle, lose 2 pounds of fat and the scale shows.... nothing. Yet that's great progress.
3) You may need to bust out the food log and track calories per day. I don't see anything wrong with what you're doing (no idea what "animal cuts" is though) and I can only assume your protein powder isn't packed with sugar, but what we don't know is total calorie count. Logging that could tell you if anything is slipping by, though your food choices look fine to me.
My guess is that you're seeing muscle gain (killer training program + good peri-workout nutrition) and relying too much on the scale rather than other, more accurate forms of measurement. What I'd suggest is getting out the tape measure and using it around the fattest part of your middle. Tracking just that measurement can tell you a lot. There's also a larger guide to tape measuring in the V-Diet plan if you want to check that out.
