When does ketosis start?

I think it's between 2-4 days usually.

According to Wikipedia, it kicks in "after about 48 hours".

To be honest, I didn't even notice it, the only difference I saw was that I was no longer feeling hunger.

I woke with a banging headache this morning and felt like I needed toast!! I did resist and now I'm not hungry at all even though I have a 200 cal meal and a tetra left! :)
I'm in ketosis by day one :)

I've got some stix so I will wait until tomorrow and find out. I think I must be because I feel different!

Thanks for the replies :)
