Body changing

I'm starting to notice my body changing. I'm eating smaller portions (about 250-300) calories every 2 hours. The calories are nutrient dense (healthy foods) with good fats and absolutely no Trans fat and very little saturated fat. I'm focusing on the good fats like flax oil which contains omega 3-6-9. My current body fat % is 20. My goal is 15%.

I did a 10 min warmup on the elliptical then worked my biceps and triceps. Ended todays workout with 15 minutes on the stair master.
