This is not how we recommend doing the program. During the first phase you will need the three shakes a day to keep your body nourished and satisfied.
For best results we do recommend trying to achieve some form of physical activity and if this is not possible we would still recommend consuming three shakes a day and a protein meal. Weight loss may be a little slower than if you were doing physical activity but your body does need a certain amount of energy to function.
