I want to sort this out and find out what to believe and what works/will work for me. Here are my issues:

Do we add fat or not? There is advice both ways and they both work for some.
Why doesn't IF seem to work for me?
Do extended fasts cause deficiencies?

The first one is the one that matters most to me. I will likely not eat in the morning when I'm not hungry, regardless of anything else. It's what I did w/o thinking about it when I was successful twenty years ago. Still, I need to figure out whether to eat fat to burn fat or limit fat so I will burn off what is stored. If I have a better handle on just what I am doing, maybe I can weather the stalls.
Thanks, Meme, for messaging me. I guess I'm back.
