My diet is very rich in protein and good fats, and carbs post workout.  I definitely eat very good.  Lots of seafood, chicken and steak.  However, my body doesn't seem to like to burn all this fat I have around the belly, chest, and mid body.  My legs are starting to look like olympic lifters, but I have so much fat stored up in upper body. 
The problem is, the second I start to eat on a calorie deficit, my strength goes down.  For example, I was able to do 5 x 255 x 3 full paused 2 sec squats.  Then, I lost 3 lb in a week, and I could barely do 1 set of that now... on the 2nd set or 3rd set, I'd fail at rep 4 or 5 and get pinned.
