hi! on one side i think, its a good thing and a good pause for the body from all the unhealthy food and the body can loose all the "poison" which our industrial food is contaminated. drink enough water,my friend and dont take it too long! the body will need vitamins,minerals and good fat for the maintenance of your brain,hair,skin etc. when the body cant get this from food,he will take it from your body and then it starts to be bad. tip:after fasting,please dont eat much as you where eating early. you need to make it step by step with kcal,carbs etc . if not,you come to the jojo-effect pretty fast.
