Diet

I'm liking the "sleep" field, though I haven't got around to shifting my template to it. Clearly that's a big factor. But the other biggie is diet, which presents some complexities but maybe not insurmountable ones. It would be cool for example to have a simple quantative scale capturing the type, quality and frequency of food intake. Have a column for meals and a column for snacks, each with a multiplier that describes quality (e.g. for meals fish or chicken, whole grain and vegetable/greens is 1; beef or pork and prepared grain is 0.75; TV dinner is 0.25, etc). Then by holding training constant over a period one could track the relationship between performance and dietary changes.

If one really wanted to get fancy a calorie counter with drop-down lists for various foods would be neat, but maybe that's too much work.
