I’m not necessarily an “oldie” yet, but I think it’s important to point out that your personal Keto will evolve overtime between learning about yourself and doing research.
When I first started out I was still drinking Diet Coke and putting Splenda in my tea.
I’ve now evolved to using liquid stevia, but still haven’t managed to kick my artificial sweetener habit altogether yet. It’s a process and easier to maintain life long I think if it’s not necessarily all done at once.
The other thing I’ve stuck to is that If i’m going to “Cheat” per se, I have only been doing it with Keto foods. I’ve had a few weekends where my bacon and mixed nut consumption was out of control, and I didn’t feel great…but it could have been a whole lot worse if I had gone back to sugar. Not to mention how much harder it would have been to go back to keto the next day!
