Has your diet become customized?

Its getting difficult to "brand" my diet under any one program :-) ...hard to explain. I evolved and morphed my diet as I learned what works for me.

This is what I'm talking about...
- Eat kind of like South Beach phase 2 most of time... really phase 1.5 :-) No bread, pasta, potato, rice, and sweets...avoid simple carbs and high glycemic load foods
- avoid red meat (AHA preference for cardiac patients...me) ... sometimes I stumble into situations where I allow it to avoid questions... Steakhouse, BBQ...
- Latest change...eat on the odd hours... 9, 11, 1, 3, 5, 7, 9, and 11. So Breakfast is at 9 (300 cal) Lunch is at 1 (400 cal) and dinner is at 7 (500 cal). Everything in between is about 100 cal. liking this. no hunger, overeating...

Usually once a day
-- Eat....Greek yogurt, grilled skinless chicken and/or turkey, scrambled eggs, Canadian bacon, grilled tomatoes, huge salad, red beans (fiber), 1 oz low fat cheese, nuts (30 Pistachios, or 15 almonds)
-- Walk a 4 mile loop for breakfast and decaf coffee. This is just a mindless routine now... rain/snow or shine.

A few times per week
-- I eat fish, fruit, melon, cabbage, sauteed spinach, and other healthy foods...maybe skip meat altogether
-- I ride my bike aggressively for 20 miles or so (about 1:20 hours:min) This is fun for me.

I'm losing weight steadily... without any real hardships.
