Since today is only day 10 for me, I don't have alot of experience, but I did lose 7 pounds the first week. I haven't weighed this week yet.
I purchased some Proti diet soup, drinks, and puddings from Nashua Nutrition @ $10.99 per box of 7. I needed some variety to what I was doing.
Been using Pure Protein bars (some have higher carbs and calories than others, so I just buy the lowest ones) and EAS RTD protein shakes.
I am only spending about $4.75 per day for my meals replacements vs. the $21 I would spend on IP products.
I know there are others on here that have been successful using alternate product. I can't wait to hear from them!
