Don't get depressed Bro... get aggressive, increase your workout intensity and that will help you burn more calories. I promise you 2 things, first, we have similar body types in the sense that we add muscle very easy, I mean just looking at your build, I know you do... second, you can and will still add mass with higher reps/lower weight workouts, if you don't believe me, just read some articles that Tony Freeman has written about his workouts and style of lifting... he is 6'2" and around 280+Lbs pre-contest... He's HUGE and he lifts very similar to the way I lift, maybe even higher reps and more intense!
Your Macros look excellent Bro, there is only one slight suggestion, if you really are serious about losing that last bit of hard to lose skin-chub, you are going to have to carb-cycle. You can still carb-cycle on LG, but it will probably lower your calories a bit, but I suggest eating a little more protein and more vegetables on those days. 3 days no carbs, 1 day of carbs (moderate/normal not going crazy) you do that for about 12-16 days and then report back to me what you think of carb-cycling... oh yeah, it is gonna suck in how you feel, but watch how good it works! Another beautiful thing about carb cycling is, while it can be tortuous when you are doing it, it does not come back as soon as you start eating carbs again, I have been eating carbs daily since Halloween and I have not gained a single Lb or % of BF, actually still losing, but way slower than when I car cycle! Anyway it is just a suggestion Bro, one that I know 100% for sure will work and work very, very well!!!
