You are making this far too complicated. Just simply giving up all the cereals, oatmeal, breads, grains, & legumes will make a HUGE difference in your life. One woman we know had lost 75 lbs in one year by simply not eating any more bread! Otherwise her diet was unchanged.
IMO, just focus on eating eggs, meat, chicken, fish, veggies, fruits & nuts. Don't count calories, don't count carbs, and keep it simple. The pounds & fat will slowly more or less fade away and your health will improve.
My suggestion: Stop being a perfectionist.
Best to you,
