It is not reccomended during 1st week as you need to give your body chance to adjust to new feeding. If you want to ask specific question, you can contact Lipotrim helpline. They are very quick via email as well.
I do 6km walks (speed 5.8km/h) 3/4 times a week. This helps to tone your body, and I believe also help weight lose without killing yourself. It also gives you good background for the healthy way of living.
