Your entry diet and exercise program is just fine. You don't have to "jump in" becuase not everyone wants to, needs to, or should live in the deep end of the pool. You (like everyone else here) will figure out YOUR "best" course over time. The changes you are already making will provide great improvements. No offense to Griff (he's a wealth of fantastic information), but he's pretty black and white with his views (all carbs are the devil and sweating is nonsense) and there's many ways to live a healthy lifestyle.
I also love to cycle (and run long & lift heavy too) and support my exercise with good carbs (fruit/veg). Use your body, enjoy plants and animals , relax ,and live your life. Some here preach fear - don't fall for that crap...
