No! The idea is to stock up on nutrients without the extra calories. Not just for people that want to lose weight! You can consume our products outside of Challenges, to be in good health or to keep fit, without giving up pleasure. Low in calories, rich in nutrients, convenient and delicious: as food should always be. Example: Drinking a clever So Shape Brownie flavour meal in the morning, is much more nutritionally complete and healthy than a chocolate drink full of sugar!
