Three day Diet plan

Weight now is 65.8kg, cannot reduce with my current lifestyle. Zi An already over three years old, I should use the three day diet plan to kick start the diet control and calary watching activity. This plan will lose 2-3kg within three days, what is more important is it will be able to let me feel light and happy. Best is to reminded of the food intake daily is actually way more than required calaries. It is just to satisfied the crave of food.... Jia Yu.
