Nope. Other than accidentally buying the wrong peanut butter (PB here generally doesn't have sugar in it, but I picked up a tub of Skippy at Costco forgetting that most American PB has sugar in it), it's been going okay. Another modification I am making is that I am going to be eating the lower carb Quorn products (such as the deli slices and mince). I can't eat too much soy because of a history of breast cancer in my family (including my sister). I am not sure if it would be included or not in the SB plan if Quorn was more popular in the States. It's a good source of protein, low in fat, and I like it. It's not carb free, and I think even the lowest carb ones have small amounts of things like barley or pea fibre in them, but I want to have another option for protein.
