As long as it works for you, I am OK with it.
But, how will you know if it’s working for you?
We’ll, first, make sure that you’re not treating it like a religion.
Some people have a tendency to get into something (anything), and then if one day that thing has to change (like, say, you feel like eating earlier) they get stuck, upset, or worse.
I think that IF has merits for sure. Another phrase for it is ‘Time Restricted Eating’; TRE is similar, but not exactly the same.
Just remember that the concept comes from the idea that our caveperson ancestors probably went long periods of time without food, and therefore, we probably evolved that way, so it’s probably good for us today.
Guess what? That’s probably true, but our cavepeople ancestors did not also have jobs, alarm clocks, or diet books telling them to fast intermittently. They simply did it because they had to. They were not on a schedule. Their schedule was nature.
Your schedule is not nature (most likely). You may need to eat to get more energy because you have a long day of work ahead of you, or because you won’t be able to eat later.
So, go with the 2020 flow, not the 20,200 BC flow.
With all of that said, I do love the idea of giving your body, particularly your digestive system, a significant period of rest. Most people do not do that nearly enough.
You should be able to eat plenty of food for the day in a relatively smaller than ‘average’ window.
Translation: eating all day and night long is likely not great for you.
Think about it: doesn’t your liver need a break?
It goes much deeper than that as well; it’s not just your liver. If your digestive systems are always on, then your body is under a constantly elevated level of stress, and some important recovery processes will not take place.
