The trouble high fat and protein foods in general is the amount of sodium. I'm limiting that also (my blood pressure is just fine unless I eat too much salt). It looks like Keto diets say to aim at 30 grams of carbs while back in the day (decades ago) 60 grams of carbohydrate was the goal of low-carb diets. Before phone apps we kept track of carbohydrates with books that listed foods and various nutrient levels. Some foods I don't want to give up, but I will keep the amounts moderate (potatoes, for example, and oranges). I'll split the difference and aim at 45 grams per day. I'm learning about ADHD, but it does explain some of the sugar binges and the love of caffeine. I hope the focus on protein will short circuit the craving for sweets, I think that is something Dr. Amen says can happen (I heard it in the lecture on PBS but haven't read the details in the book yet).
