Hi Einatbl
I think you got a lot of us thinking. If I may answer, this is how I see it.
The original diet is 5.2 on this forum. But it is evolving into something bigger and better. We all started on it, got initial results. The biggest and best result I would say is that great feeling the day after a fast, not only in the body, but mind too.
As people get stuck and not seeing changes on the scales, they ask why and what can they do to make this way of eating even better. Counting calories is one of these steps.
We adjust the eating around our social lives. And eat what we enjoy eating.
Once one have lost enough weight and feel the difference in clothes, that will be motivation enough to keep doing this. With or without counting calories.
Counting calories educate you for the rest of your life. No it will not be necessary to keep doing that. No you don't have to go as low as 1300 to get results, but it might be the next chapter for someone else to get to their goals quicker. Or break through a plateau. Without feeling deprived on days they want to eat more due to socials.
I won't say I love fast days, some days are easier than others. Some days I fast and did not plan it ahead. Other days, like today, I just can't do it. And that's allright on this eating plan, because I don't feel like a failure as I would have on other eating plans.
It is taking me longer to loose than what I thought, but I've gained much more in knowledge. Because I know it is possible for me to fast.
Some days I eat 1200 cal, other days I couldn't be bothered. And it is a sense of freedom I have. After many years of dieting myself.
In the end we are here to support each other, share our experience what works for us, and it is your decision what is YOUR next step. You build your ways of eating around your lifestyle.
I think in a year maybe less, they can write a new book based on everyone's experiences here, because the benefits are way more than just what you see on the scales. And we still enjoy all our food, even more than before! It seems we are more picky of what we do eat on feast days, the longer one have beenn following it.
All the best for you!
