Hi Grant, (& David)
I would also love to hear how you go.
I'm also a runner, training for my third marathon this September. I cut out fructose completely from my diet (after reading Sweet Poison) from January of this year through to March and instantly felt completely empowered to make good food choices (the urge to overindulge vanished!). I was amazed at how easily it became after a while to resist the white stuff and my appetite came under control. I felt the slimmest I've ever been and as a result running was easier (less impact).
In March I competed in a trail marathon where the only foods on offer were the usual fructose-laden isotonic drinks, powerbars and gels. It gave me a HUGE energy hit (after being off it for so long) that it was a bit of a slippery slide back to thinking that fructose was ok for me and I've been allowing it (in varying degrees) back into my diet.
I'm back at the stage where I'm feeling utterly lousy and out of control when it comes to eating so I have ordered book#2 and vowed once again to cut it out completely. It really was the best health decision I've made in a long time and I look forward to feeling as great as I did in the first three months of the year.
I love this forum as we can all encourage each other and hold each other accountable.
All the best & I look forward to hearing about your progress.
