It is likely that the change in diet is made to provide more zinc, vitamin D and calcium to the girl's body.
Explanation:
As shown in the question above, the girl was feeling tired and full of appetite due to her unbalanced diet. This makes a lot of sense, as an unbalanced diet does not provide the necessary nutrients for the body to function properly.
In addition, the lack of zinc in the body can trigger the lack of appetite and the lack of calcium and vitamin D, can trigger tiredness. So it is likely that the girl's diet needs to be modified so that she provides these nutrients in optimal concentrations to her body.
For this, she can add her diet foods such as: Peanuts, cashews, eggs, shrimp, flax seeds, white beans, sesame, corn, broccoli, dark vegetables, liver, cheeses and mushrooms.
