I've been doing OMAD Keto for more than a week and I can see that it's pretty effevtive. How long should I do it?
This totally depends on what you are wanting to achieve with intermittent fasting and one meal per day. If you only want to lose a few lbs and then maintain that new weight, you can change to either a longer eating window, or allowing more foods in the eating window (or both), and do what works for you to maintain that weight.
Even though most of us stumble across the OMAD diet because we want to lose weight, there are so many superb health benefits that a whole lot of people eat this way just because they want their mind clear and their body as healthy as possible.
There are also some anti-aging benefits from eating only once a day, so this is actually a way of eating that some people will do indefinitely.
It really is up to each person.
For me, I am as excited and hopeful about the health benefits and anti-aging possibilities as I am about just losing the extra weight; so for me, this is going to be a lifetime eating plan, and modified as I need to for the most health benefits.
