I think I know why cycling has been a bit hard the last few weeks. I went to give blood today and my haemoglobin level is too low. Not by much, and I'm only borderline anaemic, but it explains a lot.
Well, I think I might always have had a tendency to a low level of iron in my blood. I recognise how I feel, and it's what I sometimes used to feel like when I was thinner. The only times I've actually been diagnosed anaemic, though, were when I was pregnant and then I used to feel awful and iron tablets, given out routinely in those days, were not enough and I used to have to have beastly iron injections and then follow up with double iron rations, if you see what I mean, to keep my iron level up to an acceptable amount - which for me is over 12. At present, it's 11.4. If it were about 10, I'd feel awful, so I don't want to get worse.
I suspect that generally eating a bit more has kept me going over the past few years. Mind you, I have been aware of iron levels, which is one reason I've been eating more red meat than I would have if I'd been trying to lose weight quickly.
However, I've been eating less meat in the last couple of months or so, largely because I've been eating more fish. I still have lots of vegetables, wholemeal bread and a generally good diet, but it's evidently not enough. So it'll be steak for dinner tomorrow and I'll up my consumption of eggs, dark green vegetables and such things. I will also take an iron supplement - Weeza recommends Floradix - until I feel right. I'll know when I am.
I haven't lost any weight recently, but then I haven't been trying to. As long as I don't put any on, I don't mind for a month or two.
