My big sister says any container of ice cream is a single serving
I don't think we should compare keto foods to the non-keto foods they represent.
Keto ice cream isn't as good as regular ice cream, keto bread isn't as good as regular bread, keto macaroni isn't as good as regular macaroni, keto cookies aren't as good as regular cookies. We just have to accept them for what they are and either like them on their own terms or not.
On the other hand vegan burgers aren't as good as regular burgers, vegan sausage isn't as good as regular sausage, and so forth.
When we adopt a WOE we simply have to find what we like and what we don't like in that WOE. Forget about ultra creamy ice cream loaded with insulin spiking cane sugar or high fructose corn poison. Either you like keto ice cream or you don't. Period.
I eat keto ice cream, keto bread, and other low carb-high fat foods that taste different from their traditional counterparts.
But I also get to eat bacon (m-m-m-m-m-m-m-m-m!), butter, and heavy whipping cream in my coffee.
Some things about keto are better!
