She does play sports, but nothing too intense and only during the school year. Nothing this summer to speak of that would have affected the plots I posted. She has never been on a restricted carb diet. She eats whatever she wants to. We've eliminated certain foods from the house such as soda, glucose based candy, and we avoid hamburgers because the fat and/or protein content makes her BG hard to manage afterwards. She's never been interested in those kinds of food anyway. She's not the type to pig out on food even if give the opportunity. Sometimes if we're out to eat she may end up having a meal totaling 120 carbs or more. We just watch the CGM more often after such a meal to be sure it was bolused for correctly. If there is one thing she's had to adapt to, it's breakfast. Anything over 40 carbs will cause a big spike. So she eats breakfasts in the 30-40 carb range usually, with things like eggs or yogurt or milkshakes that are low in glycemic index, but once lunch comes she can eat whatever she wants to.
