Rice crackers and cheese? Rice noodles with cheese or in a super salty broth with meat? GF pizza? Mashed potatoes made with cream, sour cream, or butter and cheese? Cheesy rice with tomato sauce? Cheese quesadillas on corn tortillas? Cornmeal porridge with butter/cream and honey/maple syrup? Rice pudding?
Ok like, I ate zero carb for 14.5 months. And when I started eating carbs again I experienced a lot of the symptoms you’re describing: fatigue, super fun mood swings, digestive issues, did I mention fatigue etc. They lasted for months. Like 6 months sounds right. Was it worth it? Absolutely yes.
You mentioned you’ve been following Matt’s protocols for 5 days. I mean, I’m assuming you’ve been eating carbs again for longer than that but even so, this shit takes time.
One thing that helped me was just sticking to mostly starch at the beginning. It was a while before I could eat sugar without it making me feel crappy.
