It's a Standard American Diet convention to worry about "getting enough protein." Now, coming OFF a meat diet can certainly cause discomfort, but make sure you read about common cleansing reactions (foggy brain certainly one of them)--you may be misreading "wacky brain" to be "so many carbs"--- it's far more likely that you're in the cleansing process and experiencing an adjustment.
Nothing better you can do, if you're prediabetic, than this detox. Eating meat is a BAD idea for diabetics and prediabetics, and carbohydrates have been 60-80 percent of humans' fuel source across cultures, forever.
