Write a letter about brother/sister suggest not to eat junk food

Dear sister,

I am writing this letter to express my concern about the way you eat. I have observed that lately you are not eating a lot of healthy food and instead you only eat junk food.

You should know that this food is harmful to your health and that over time it can cause serious problems.

Like your brother, I ask you to please have a balanced diet and take good care of yourself.

I love you.

i don't really know the circumstances. i personally think not due to it not being fair for all parties and how hated i'd become if i thought it was a good thing.

there is no sentence to look at.
