I am older, 53, and suffered an injury that prevented lifting for a long time. I have since really only been doing cardio but due to poor diet for over a year, gained a lot of fat. I ran on a no carb/lo carb diet for about 6 months and lost only 15 lbs or so, but with a tiny bit of recomp.
6'0"
250lb
% body fat -- being 15-20% at a strong 215 I don't even want to check until I drop 30lb or so

I am so flabby that I had to do something so started on a strict cutting diet this week. I calculated my TDEE and requirements for going from 250 to 200lbs, and have been dialing in a diet with macros as per below.
I do 25-30 min of intense cardio 5-6 days per week, and will start adding body weight exercises this week.

My question is this--I have a crazy busy schedule, so some meals are on the fly. I also cannot eat the volume easily of the clean diet, so may want to skimp on some of the meals. If I need to skimp, would it be best to skimp on the carbs portion?
I started using a protein shake to decrease fullness.

Daily diet

Meal 1 90c, 45p, 10f
Meal 2 (Pre-w/o) 90c, 45p, 10f
Meal 3 (Post-w/o) 90c, 45p, 10f
Meal 4-6 45p, 10f

Food selection right now is off the macro list from the forum. No junk, no refined sugar. Lean chicken, fish, occasional ground sirloin, fresh fruit and veggies, milk/juice x pre/post workout only for protein shake and to decrease food volume.

Work-outs
Trail run in desert 3-4x per wk, slow steady pace x 25-30 min
Elliptical HIIT 1-3x per wk, x 25 min

Body wt exercises to be added

Supplements: test cyp 100-150 every 10-14 days

I must have been eating pure sh*t to have gained this much weight and not have been full all the time. Eating clean fills me up. Trying hard to cook meals on weekends and have for the week. I have a wife and two kids so hard to spend much time making meals every day, but not wanting to eat processed foods.

Any suggestions appreciated on making diet prep more efficient and aiding in fat burning with exercises.

Thanks for help!
