Andrea, I have been on vacation so just catching up with your Journey.
Good luck with those meetings and happy hours with clients.
I think you are correct that using olive and avocado oils might help. Also ghee is a good thing, makes things taste so great.
ZC is not for everyone. Just like 80-100% carbs is not for everyone. We have to keep trying to see what works, bravo for you in tracking and reporting on your n=1 experiment. I am sure you will find the key. For me it was first switching to keto, then LCHF, then fasting. I stalled out here and there but did reach my goal, even exceeded it by a few lbs. If I can do it at my age, your 35 yr. old bod can do it too. Hang tough, you got this.
