Don,
I used to be 250 lbs @ 6' 2" and have made changes over the years to where I am now 190 lbs or less. Throughout this journey I've experimented with almost every type of eating style and I firmly believe that learning what works with your individual system far outweighs meal timing, etc. I'd recommend purchasing either Paul Chek's "How to Eat, Move and be Healthy" or "The Metabolic Typing Diet" by William Wolcott. Metabolic typing will give you a much clearer perspective on what you personally should be eating and in what ratio.
Any struggles with eating can be attributed to something you're consuming that doesn't jive with your system. Identify and remove foods that cause inflammation, cravings, etc. and you'll start to figure out your optimal times to eat given your schedule.
