I have seen that in the Bredesen protocol, intermittent fasting is an important part of it. At least 12 hours of fasting per day are recommended, but for APOE4 people, I believe it is stated that it is best between 14 and 16 hours.
A question I have is: is coffee considered to break the fast? (I assume nothing is added to the black coffee). I have seen this question asked several times in youtube, and I believe Satchin Panda, interviewed by Rhonda Patrick, stated that it could be that black coffee breaks the fast, but other people believe coffee does not break the fast.
This is relevant to me since I am unfortunately hungry when I wake up. I usually have dinner at around 7:30pm. So, I should have breakfast not earlier than 7:30am, and probably it would be best to wait until 9:30am or even 11:30am.
I usually wake up at 4:30am, but as I have said in another thread in this forum, after taking a melatonin pill I woke up at 7am two days on a row.
So, I am wondering if I could try to get used to not having breakfast. It would be hard, but if I can take coffee, maybe it is doable. If taking coffee breaks the fast, then I see it unsustainable for me.
What I could do is then fast in the morning until noon, and then do one hour of exercise (I believe it is stated that doing exercise fasted is a good decision), and have lunch at around 1:30pm. In this way, I would fast 18 hours, which probably would be "good" (but Prof. Valter Longo states that people that skip breakfast have, epidemiologically, worse health outcomes).
Is anybody doing something similar to this? (not having breakfast, but drinking coffee, and exercising just before lunch, which becomes the first meal of the day).
