On the Nutrisystem Diet, each and every meal is pre-packaged and sent to the client. This method makes the diet easy to stick to and relatively easy to maintain. Opponents of the diet say that Nutrisystem is effective in losing weight quickly, but may not help keep them off. Tori Spelling is one of many celebrities who has endorsed the product, using it to lose weight following the birth of her son, Liam. Dan Marino has also endorsed Nutrisystem and worked as their spokesman.
