My fasting is quite mild. I only eat two meals in a day for more than a year now. I don't really exercise in a daily basis. I just cook for two hours every meals because we're 7 here in the house. And I walk about 15 minutes a day. That's it! But its really a struggle, it won't work on a one night stand and suddenly you're already eating twice in a day continuously. Takes time and effort and discipline.
