As I mentioned 9 days ago; after an interesting tweet from @SportieDoc and reading the book she recommended (Taubes - Why We Get Fat and what to do about it), and another (The Art and Science of Low Carbohydrate Living), I've been trying very low carb nutrition. It's been interesting and weird and it feels like hacking my metabolism, which it pretty much is; I'm trying to flip a switch to get my body to use primarily fat as a fuel for most of what I do.
|Sunday morning breakfast|
The first day of this experiment felt like a normal day but with mind-bendingly tasty foods. Day two, was pretty similar and I felt no different. Days three and four I started to notice a change... I was feeling more alert and then increasingly full of pep to the point of almost irrepressible. Most interestingly I was eating three times a day and not feeling hungry at all in between, not feeling hungry when I woke up, not thinking about food aside from working out what to make at mealtimes as I'm not routinised into a set of recipes yet. I wasn't missing or craving breads, potato, rice, couscous, pasta etc. and didn't feel like I wanted anything sweet; moreover I was drinking much less tea and a cup or two of filter coffee a day.
I'm still reading lots of articles (like Joe Friel's one on becoming a better fat burner, and Dr Runyan - a diabetic Ironman finisher) and books and looking forward to cracking through The Art and Science of Low Carbohydrate Performance to get a bit more understanding about what I need to be doing and how I get to being a proper fat-fuelled athlete. What is still very clear is that the details an fine tuning are not well-known or understood, and in fact not known much at all, and that there is an appreciable amount of thinking that low-carbohydrate fuelling probably has a detrimental effect at the top-end exertion level; but then I'm not a 100m runner, or even a professional athlete at any sport and I'd rather be able to get through the bike leg of a 70.3 without needing to stuff my face with bars and gels than gain an extra 3-4 minutes off my time through top-end power (as I'll gain those 3-4 minutes back through not faffing about eating on the bike).
Oh, and I've incidentally lost 1.9kg since I started (OK, yes most of that will be glycogen and water, but still...)
The experiment continues!
