I think it takes a long long time for your body to completely switch to fat burning, like 4 to 6 weeks of strict keto. I’d just be concious you’re signed up for long term.
One thing I did not like about it was spending every waking minute thinking about what I can and can’t eat, planning, reading labels. If you enjoy food then I can imagine it being even more of a challenge, but I mainly just eat to keep going and bread, pasta, rice are easy go-tos for everyone aren’t they?
The keto world is weird, there are blogs and blogs about creating pizza out of just meat and cheese. Which sounds incredible, but is very hard to do and will end up being a disappointment.
