I don't really understand the whole food argument, but maybe it is because it is the one areas of training I don't really give a f*** about.
I eat when I am hungry, I don't care if it's chocolate, red meat, butter full fat gold top jersey milk. I notice no difference in training. As long as there is sugar in my blood; I function. When I went out on a club run the other day, everyone pretty much bought a coffee and ate a couple of biscuits. I went and bought 2 mugs of tea and the biggest slice of chocolate tiffin ever and I got some very odd looks. To be honest I felt a bit guilty, but the way I saw it is that i'd already done 40 miles and burned 1600 calories. I'm not exercising to lose weight, at the moment i'm losing weight organically about a lb a week, so by summer I should be my ideal weight of 10 stone for climbing.
The only reason I can think of is that i'm pretty young? (22) Maybe as I get older what I eat will affect me more?
The only consumption which I feel really affects me is alcohol, but that is obvious. The only problem being I don't feel right exercising at all for about 2-3 days afterwards, which is why I am near enough tee-total now. Caffeine doesn't work with me either, makes my legs burn.
