what does she eat nowadays? amounts and timing of protein, fat, fiber/carbs?

My obese 8 yo grandson is hungry all the time but it can be explained by how much protein and starch he eats. His parents have not transformed the family diet the way you have. He had minimal antiobiotics but yes, regularly for ear infections.

But I'm wondering if your 10 year old has high insulin from something other than carbs. Protein, gut, inflammation,?
