About 1-2 hours after running yesterday evening, I was cooking some salsa in my kitchen.
When adding some lemon juice to the salsa I suddenly had a craving for the lemon and basically ate half a lemon.
Is this craving caused by the running? If so, does it indicate that my body was missing some kind of nutrition, that it was hoping to get from the lemon?
According to a random internet chart that I'm not entirely sure I trust, craving acidic things is a sign of a magnesium deficiency.
If you're low on magnesium, it's likely you're low on other electrolytes. It's one of those things you'll sweat out and need to replace. You might want to consider drinking some sort of electrolyte mixture instead of water, or taking electrolyte tablets.
My personal (anecdotal) experience is that after an hour or more of sweaty exercise, I'll tend to crave water, salt and sour, and that drinking electrolyte-laced water during exercise helps significantly.
