This has been the story of my life for 12 years. On the chart at like 12%, then off the chart, then back on the chart, but height has always remained steady at 25%. Mine's diet seems like yours. All the fats in our house our full fat, whole milk everything. I remind her to eat a snack when she comes home, I send snacks for sports practice, often she does not eat them. If I did not actively put food in front of her and we did not have sit down breakfast and dinner, I am not sure she would actually ever eat. Food is never on her radar.
After a very long nordic ski race, I did take her to a restaurant and she ate 2 adult dinners. I know she can.
I let her make "trail mix" She picked the nuts, and dried fruits from target and traders joes. It has all her favorites, so she is taking that and snacking all day.
I hear you and I have no answer for you, it seems to come and go with us, this winter was super tough, this summer we are doing awesome.
