The people who’ve been doing this for years - I’m seriously impressed!
I think I reached a milestone today. I ate a good sized breakfast at 9 am and then went off to work, with my lunch/dinner packed. At about 2:30ish I felt suddenly very nauseous to the point I thought I might throw up. I had some water and it passed but then, for the rest of the day, I never got hungry again.
It’s now 9 pm and I’m still not hungry. I must be successfully into ketosis now.
