Carb Manager - Keto Grades

A is Keto friendly. B is eat in moderation. And c is not at all 

I haven't received a C. I know A is very Keto and F is not at all. There's probably a breakdown somewhere

Missmayhem oh dear... 

Keto Grade C is Strictly Limit.  Lactaid whole milk is in that catagory.  Practically speaking, stick with Grades A and B on a daily basis and fit an occasional Grade C in.

A - Keto approved

B - limit

C - strictly limit

F - avoid entirely

Onions have carbs.  You can caramelize onions because of the sugar in them.  "F"
