Well, I was very happy this morning, when my scale told me 69 kg. Also it thrilled me to hear that someone wanted to join, and another one considering it.
It's always nicer, more interesting and challeging to do things together.

This morning I had to run to the toilet three time, to do business, which made me think of : Better talk about dehydration. Also it is summer, ones get hot and sweaty.

So it is very important to give the body back essential fluid. Through sweating and a kind of diarrhoea the body looses not only water but also a lot of minerals. Those have to be replaced by drinking not only water but mineral water. There are mineral- and vitamin supplements available that can be deluted in water, or be bought directly as a drink. To be on the save side, it's good to include such a drink into the program every day ,or at least every other day and an extra little sprinkle of salt into your soup. 

What I like to mention to is that I'm not a medical person. I only can speak of my own experience and the few morsels of knowledge picked up here and there. But I surfed the internet this morning and there is heaps of material on fasting. Also Amazon offers various books on the subject.

Two sides I found kind of recommendable:

Sorry, if there is no link, I don't know how to create one.

It's one o'clock and I better have my lunch (but feel no great hunger) and my lie-down.
