Wow --- New Lifestyle Diet looks wonderful. I looked at the puddings and the RTDs.
I found replacement RTDs at Fit RX
www.fitrx.com - brand name Labrada. Costco carried these for a while, and the vanilla ice cream tastes amazing. A 14 oz bottle has 180 calories, 7G fat, 5g carb, dietary fiber 4g, sugar 0g, protein 25g. For orders over $99 the shipping is free. Costs $28.95 for a case of 12.
While I am very pleased with the IP plan, the cost is starting to mount up, so it helps to find alternatives.
