Your calories look very close to right. I would have suggested between 2496 to 3120. If you aren't making gains anywhere but around your middle, you may need to review your macronutrient profile.
Something along the lines of:
45% carbs, 35% protein, 20% fat. Adjust the balance slightly here and there until you start growing in the right places. More carbs before and after the workout, less carbs and more fat far, far away from your workout.
If you don't get enough carbs around the workout you don't get a nice insulin response. Insulin is the most anabolic hormone there is - moreso than testosterone. It is the real "growth hormone". If you have a nice hyperinsulin state around your workout you will put nutrients into the muscle and grow there. HST works perfectly for natural anabolic nutrition because of the full body workouts.
If you create a hyperinsulin state too far away from your workout then you will also store your nutrients - in your fat cells.
An example of this - and it's only an example of what works for me, not a guide since our weight is a lot different - I'm 200lbs at 9% body fat right now. But from it you can see how to time your foods better to get the results you want.
M1---2 cups skim milk, 2 scoops whey, 1 banana
WORKOUT
M2--2 cups skim milk, 2 scoops whey, 1 banana + 35g dextrose in koolaid + 10g creatine (immediately postworkout)
M3--2 cups skim milk, 2 scoops whey, 1 banana (1 hour post workout)
M4--1 chicken breast with kraft carbwell bbq sauce, 1 cup baked beans, 7.5 ounces whole kernel corn.(3 hours postworkout)
M5--1 chicken breast with kraft carbwell bbq sauce, 1 cup baked beans, 7.5 ounces whole kernel corn, 2 green vegetables (3 hours later)
M6---1 six ounce steak (usually a rib-eye or chuck eye (ground chuck works too and is cheaper), 1 medium plain (salt and black pepper only) baked potato, 2 green vegetables. (3 hours later)
Go to bed...unless I'm up late surfing the net.
Get up during the night and have peanut butter on 100% whole wheat...that's why I'm up posting this right now.
Since beginning this 2 months ago I've gained 27lbs and lowered my BF% from 13 o 9...that means only about a 2.5 pound fat gain on a bulker...and gaining more muscle+water than fat. Abs are better, visible vascularity is better. I owe it to the full body workouts and the nutrition plan, and a little TRT from the doc - just enough to raise my test to that of a normal 37 year old male instead of an 87 year old woman.
Good luck to you, now all you've got to do is to find the right nutrient profile for your body and get the timing right for your body.
